General technical information

How is paperboard tested? Which EU regulations apply to paperboard material?
What kind of pallets can the paperboard be delivered on?

General Technical Information is a collection of technical information designed to give customers a general picture about everything from testing to delivery forms, information that can ultimately affect the end result both in terms of productivity and function.

The information includes an overview of various kinds of paperboard and advice about how the paperboard material should be handled before it is used. We hope that these recommendations and advice will make it easier to use Invercote and Incada.

At we are gradually making our information material “The Iggesund Anchor Material” available and searchable for everyone who would like even more detailed information about both the technical and aesthetic aspects of paperboard.

Paperboard handling

The correct handling of paperboard is very important for achieving the best results in printing, conversion and use. To ensure this Iggesund Paperboard recommends the following procedures to printers, converters and users.

Recommendations to printers/converters

Before printing

The paperboard is identified by the order number and the pallet or reel number. It is essential that these numbers are recorded to provide identity and traceability throughout printing, conversion and use, or that you keep the labels until the job is finished. In the case of doubt about the performance of the paperboard or its compliance with specifications, it is a requirement to provide this information and relevant samples to Iggesund Paperboard.

During printing/converting

The moisture-proof wrapping must not be removed until the board has attained the temperature of the environment concerned (printing room etc), see table 1.

Pallet or reel weight (kg) Temperature differences board - printing room (print room temp. about 20°C)
  10°C 20°C 30°C
400 2 days 2 days 3 days
800 2 days 3 days 4 days
1200 2 days 4 days 5 days


When cold paperboard is exposed to a warm environment the air adjacent to the board can be cooled below its dew point (point of condensation) and this moisture is then absorbed by the board. The time for temperature equilibrium to be established varies depending on the temperature difference and the weight of the board (pallet or reel). Therefore the wrapper should never be removed before the board has reached the temperature in the printing room.

Recommended climate in the printing/converting room to prevent curl and/or misregister is 45-60 % relative humidity and a temperature of 20-23°C.

The moisture content of paperboard can rise as a result of its exposure to air at high relative humidities, during periods of wet weather. It can also occur as a result of the condensation effect in cold weather discussed above. The result of moisture absorption can be waviness at the edges of the sheets and a general tendency for upcurl i.e. curl towards the print surface. If wavy sheets of board are printed creases may occur at the back edges of the sheets as they pass through the offset press, misregister may occur, together with press misfeeding, wasted sheets and loss of output and efficiency. A paperboard which has a high moisture content also becomes tough and difficult to cut.

The moisture content of paperboard can fall as a result of its exposure to air at low relative humidity. This can occur during very dry weather and also occur in centrally heated buildings when the external air is very dry and very cold. A paperboard which is too dry may also become wavy, develop downcurl i.e. curl towards reverse side of the board and become brittle. These features can cause misfeeding and the board will be difficult to crease satisfactorily.

Avoid rubbing or touching the surface of extruded/ laminated board because the corona treatment is easily damaged.

After printing/converting

Paperboard in sheet form should be rewrapped with moisture-proof material after printing.

Rewrapping is particularly important in order to ensure good register when board is printed in two or more passes through the printing press. It is also important to wrap in this way to achieve good register between the print and the next process e.g. cutting and creasing, guillotining or bookbinding.

Paperboard products should be wrapped in moisture resistant material after conversion and prior to shipment to the customer (end-user) or to further conversion operations.

Recommendations to end users

Before use

The supplier´s order number identifies the material. For the purpose of subsequent traceability, should this be necessary, we recommend that you should record this number and maintain the identification of the material.


The end user should also observe the precautions regarding the achievement of temperature equilibrium prior to unwrapping and use, see warming up time table 1 previously presented. Unused material should be rewrapped.

The end user should rewrap any unused material which would otherwise be exposed to the atmosphere of the work environment for an extended period. Some end users, as a consequence of their process, may have environments which are either excessively damp or excessively dry compared with the range of 45-60% relative humidity, and in such conditions there would be a tendency for the board to either gain or lose moisture with a consequent change in shape or loss of flatness.

Recommendation of time limit for board in store

Iggesund Paperboard has chosen raw material, chemicals and processes which will support stable and long life-time of the manufactured products, without deterioration of the board properties.

However, even if the board is correctly handled optical as well as physical properties may change with time.

Iggesund Paperboard recommend a maximum of 1 (one) year time limit, from delivery, for board in store.

For plastic coatings and laminations see specific recommendations, in sections "Plastic coatings" and "Foil and film laminates".

When uncertain whether to use board or not beyond the recommended maximum year time limit which is often possible, please contact your Technical Service representative for advice.

It is not always possible to deliver certain sheet sizes as single pallets. The option will be twin pallets with the new codes 2CDL, 2CDS, 2DFL and 2DFS.

Transport packaging

Transport packaging is used to maintain the quality of the delivered paperboard and to protect it during handling, transport and storage.

Reels have cores made from recycled paper and core plugs from particle wood. The reels are either packed with end protecting corrugated kraft board coated with a water barrier (polyethylene 15 g/m²) and stretch wrap or only stretch wrapped. The stretch film is low-density polyethylene. The labels are made of bleached kraft paper, occasionally plastic labels are used.

Pallet packs consist of pallets of 100% wood covered with a protective polyethylene sheet. The paperboard pile is protected on top by a sheet of polyethylene and from the Swedish units also by a thick back-to-back laminated sheet of paperboard. The whole pallet is then shrink-wrapped with medium-density polyethylene. Labels are made of bleached kraft paper.

Ream packs are made from bleached kraft paper coated with a water barrier (polyethylene 10 g/m²). Labels are made of bleached kraft paper.

The materials used for the transport packaging meet the requirements in the EU Directive EC 94/62.

Test methods


This section contains an alphabetical list of the tests by which paperboard is evaluated during manufacture. The list is divided into two parts

  1. Basic board property tests
  2. Extrusion/lamination property tests

These test methods evaluate the board properties which influence the appearance and performance. Important test values (technical data) for the individual board products are quoted on the board data sheets in the sections Paperboard products and Plastic coatings and Foil and film laminates.

The board making process is described in the document Paperboard – the Iggesund Way, which also explains which aspects of the process are responsible for specific board properties.

The Paperboard Reference Manual deals in further detail with the board properties in terms of appearance and performance, and how they influence the printing, converting and use of the board.

Basic board property tests

All tests and measurements related to the paperboard products are made after conditioning to 50 ±2% relative humidity and 23 ±1°C. Board performance properties are measured on samples taken ex machine.

Bending Bending stiffness, bending resistance and bending moment, see Stiffness.

Brightness See Optical properties.

Caliper See Thickness.

Cobb test See Water absorption.

Colour See Optical properties.

Gloss The gloss of the paperboard surface is measured in accordance with ISO 8254-11). The gloss is expressed in % units. The surface of the board is illuminated at an angle of 75° and the reflection from the surface is recorded by a photo-electric cell.

Within Iggesund Paperboard a surface having a measured value < 40% board gloss is regarded as matt. A medium gloss board is in the range ≥ 40% to < 70%, and a high gloss board has a value of ≥ 70%.

Grammage The grammage of the paperboard is assessed in accordance with ISO 5361). Grammage expresses weight per unit area and is measured in g/m².

Ink absorption Ink absorption is measured using an internal test method. The ink absorption is expressed in % units. A specific ink is applied to the paperboard surface. The amount of ink absorbed in a given time is assessed by % reflectance compared with the unprinted surface. Porométrique ink No. 3809 from Lorilleux is used for the testing of ink absorption.

Interlayer strength See Ply bond.

Moisture content The absolute moisture content is measured in accordance with ISO 2871). It is expressed in % of the paperboard weight. The moisture content of the board is measured continuously on line on the board machine and recorded.

Opacity The opacity of the paperboard is assessed in accordance with ISO 24711). The measuring principle is based on comparison of reflectance for a single paperboard sheet over a black background compared to an opaque pack of paperboard samples. Opacity is expressed in % units and readings close to 100 mean no show through.

Optical properties The term whiteness is often used as a comprehensive expression for some of the optical properties of the surface of paperboard, although whiteness is also a specific value that is measured today. The properties quoted here are CIE-whiteness, Brightness and Colour.

Where paperboards include fluorescent whitening agents or FWA’s (sometimes referred to as optical brightening agents or OBA’s) measurements are made using an illuminant that contains a controlled element of ultra violet (UV) light.

All values are measured at both Iggesunds Bruk and Workington using Datacolor Elrepho instruments.

Optical properties, CIE-whiteness CIE-whiteness (W) is a comprehensive term used to express the visual impact of near white surfaces by means of a single value. This value, based on CIE (Commission Internationale de l’Eclairage) tristimulus values, describes perceived whiteness in outdoor UV-rich illumination. A large number of equations have been developed to calculate whiteness, but CIE-whiteness is perhaps the most commonly used. CIE-whiteness is measured in accordance with ISO 114751).

Optical properties, ISO Brightness This is the diffuse blue reflectance factor measured at an effective wavelength of 457 nm. As the measurement is only carried out in the blue region of the spectrum it is of limited usefulness. ISO Brightness is measured in accordance with ISO 24701).

Optical properties, Colour To quantify the impression of colour to the human eye of a nearly white surface, the CIE colour space can be used. Three reflectance figures L*, a* and b* known as the CIELAB co-ordinates are measured using a standard light source. The coordinates a* and b* measure colour. Positive figures for a* express redness, negative figures greenness, and positive figures for b* express yellowness, negative figures blueness. L* is a percentage which measures luminance on a scale where black is zero and pure white is usually 100%. Colour is measured in accordance with ISO 5631-21).

Ply bond The interply or interlayer strength of the paperboard is measured in accordance with TAPPI 5691). Ply bond is measured using a Scott Bond type tester and is expressed in J/m2.

Smoothness See Surface roughness.

Stiffness A number of methods of measuring stiffness are recognised. Values for the following methods are quoted in this catalogue

  • Bending stiffness L & W 5°
  • Bending resistance L & W 15°
  • Bending moment Taber 15°

1) DIN = Deutsche Industrie-Norm: ISO = International Organization for Standardization: TAPPI = Technical Association of the Pulp and Paper Industry: BS = British Standard: SCAN = Scandinavian Pulp, Paper and Board Testing Committee.

Since the stiffness is related to the orientation of fibres in the sheet during manufacture, two values are given: for the machine direction (MD) and the cross direction (CD).

Stiffness, Bending stiffness L & W 5° Bending stiffness L & W 5° is measured in accordance with ISO 56281), DIN 53 1211). The bending stiffness is expressed in mNm.

Stiffness, Bending resistance L & W 15° Bending resistance is measured in accordance with ISO 24931). The bending resistance is expressed in mN.

Stiffness, Bending moment Taber 15° Bending moment is measured in accordance with ISO 24931). If the bending moment is expressed in mNm, the following relationships apply: Bending moment (Taber 15°) = Bending resistance (L & W 15°) x 0.0483

Bending resistance (L & W 15°) = Bending moment (Taber 15°) x 20.70

Note: If Taber is expressed in gcm the following conversion applies Taber: in mNm = Taber in gcm x 0.0981


The pH scale. Click to enlarge. 

Surface pH
Surface pH is measured on a water extract. It is expressed in pH units on a scale of 0-14.



Surface roughness Surface roughness is measured in accordance with ISO 8791-4, using the Parker Print Surf Roughness (PPS) tester at 1000 kPa using a soft backing (S10). The surface roughness is expressed in µm. Lower results indicate smoother surfaces.

Uncoated surfaces are measured using the Bendtsen method and the roughness is expressed in ml/min. Lower results indicate smoother surfaces.

Surface strength
The surface strength is measured in accordance with ISO 37831). The strength is expressed in m/s. This test evaluates the ability of the surface to withstand picking and blistering and is carried out using an IGT Printability Tester using a medium viscosity oil. Where strength is expressed in N/m the following correlation applies.

Surface water absorption See Water absorption.

1) DIN = Deutsche Industrie-Norm: ISO = International Organization for Standardization: TAPPI = Technical Association of the Pulp and Paper Industry: BS = British Standard: SCAN = Scandinavian Pulp, Paper and Board Testing Committee.

Taint and odour Taint and odour is assessed by members of trained panels assigning numerical ratings and recording their impressions of tainting flavours or volatile smells experienced. All our paperboard products are tested by the Robinson taint test based on DIN 10 9551). As the Robinson test is based on a comparative assessment using a panel, the results between laboratories, and even within laboratories, may not necessarily be reproducible.

GC (Gas Chromatographic) and Mass Spectrometer methods are used for assessing and identifying paperboard components and those arising from printing and conversion processes.

Our laboratory for sensory and chemical analyses is accredited for sensory analyses with the accreditation number 1740. Accredited laboratories are appointed by the Swedish Board for Technical Accreditation (SWEDAC). The Swedish accredited laboratories meet the requirements laid down in the European standards EN 45001, and EN 45002 as well as their international equivalent ISO/IEC Guide 25.

Tearing resistance The measured force required to tear a paperboard sheet is given for machine direction (MD) and cross direction (CD) respectively. Tearing resistance is measured in accordance with ISO 19741) and is expressed in mN.

Tensile strength The tensile strength is the force required to rupture a strip of paperboard. Values are given for machine direction (MD) and cross direction (CD) respectively. The tensile strength is measured in accordance with ISO 1924-21) and is expressed in kN/m.

Thickness The paperboard thickness is measured in accordance with ISO 5341). The thickness is expressed in µm. Caliper (pts) is also recorded for reference on specification sheets, where pts are inches/1000.

Water absorption, Cobb test The surface water absorption is measured using the Cobb test in accordance with ISO 5351). The water absorption is expressed in g/m².

Water absorption, Wick test Water absorption at the paperboard edge is measured using a Wick test. The paperboard surface is sealed with waterproof tape on both sides. The sample is weighed, placed in water at 80°C for 20 minutes and reweighed. The amount of water absorbed by wicking is expressed in kg/m².

Whiteness See Optical properties.

Wick test See Water absorption.

Extrusion/lamination property tests

Adhesion See Surface strength.

Grammage Coat weight is measured continuously along and across the board web. It is expressed in g/m2 and can be used for calculating the coating thickness.

Pin holes Pin holes are microscopic holes that might appear in the plastic film during the coating process. These are very small; they are not visible to the human eye. A limited number of pin holes are of no importance in most cases. Pin holes are determined by exposing the plastic coating to dyed alcohol for a certain period of time and counting the number of coloured specks. The presence of pin holes is expressed in number/m2.

Surface roughness Surface roughness is measured using the Parker Print Surf Roughness Tester. The surface roughness is expressed in µm. Lower results indicate smoother surfaces.

Surface tension See Wettability.

Surface strength Plastic adhesion (surface strength) is a dimensionless property defining the relation between adhesive and cohesive strength in the board surface. The internal method involves pulling a strip off the coating of the board and determining the degree of failure in the interlayer. Adhesion is also measured as peel strength at 125° angle and is expressed as N/cm width.

Wettability The wettability of a surface decides whether a printing ink or a glue will stay on and adhere to a surface. It is measured as the surface tension of a standard liquid which just wets the plastic surface. Surface tension is expressed in dynes/cm. The surface tension of a plastic surface is usually too low for printing or glueing. The surface is therefore treated to improve the wettability.

Products and use

Product performance

Demands for promotion and protection define the performance characteristics of paperboard, as do the requirements during conversion and distribution. The overall demand for minimum use, resource efficiency, competitive products and efficient systems requires paperboard with high performance combined with good fitness for use.

Iggesund Paperboard products are developed to provide high performance for the specific uses. In marketing, sales and technical service fitness for use and performance requirements are matched to ensure efficient solutions for each use. More information is found in the Paperboard Reference Manual.

Standard product specification and traceability

All products are manufactured to meet the specifications as described in the sections Paperboard Products and Plastic coatings and Foil and film laminaties in the Product Catalogue. Review of the specifications is documented and performed according to the procedures in the Quality Management Systems within Iggesund Paperboard.

The correct application of specification tolerances provides the printer, converter and ultimately the end-user with the assurance that the paperboard supplied has been produced under carefully controlled conditions in order to meet market quality requirements. In the manufacture of its products Iggesund Paperboard continuously strives to minimise deviations from specified target values. To meet our customers' demands for quality and consistency we also specify upper and lower tolerances as appropriate. In the control of product quality Iggesund Paperboard uses on-line as well as laboratory measurements to monitor on at least a minute by minute and also hourly basis, according to documented procedures.

Our guarantee

Iggesund Paperboard guarantees that the material our customers receive has been assessed by sampling using both on-line and laboratory techniques. Quality parameters and all sample measurements are based on samples taken ex board machine and have been found to be within the published and agreed tolerances as detailed in the current edition of the Paperboard Product Catalogue or approved amendment. Iggesund strongly recommend the full testing of the product at every stage through the supply chain before going into full production. Your local Technical Service contact should be involved to achieve maximum product performance.

In situations where there are doubts about the performance of the paperboard or compliance with the specifications, tools are available to trace information related to the product and/or order.

The Iggesund Paperboard document Terms and Conditions of Trade 2015 constitutes the whole agreement between Iggesund Paperboard (Seller) and the Buyer and here it is stressed that in the case of a claim, the clear identification of the goods is a requirement. This is to enable above mentioned traceability to relevant product data.

For the customer, the key to traceable information is the order number and package number as this information is the link to all product data and laboratory and machine records. Retrievable data are stored for a minimum of two years.

Procedures and systems are in place to achieve the necessary traceability back to Iggesund Paperboard´s suppliers.

Taint and odour neutrality

The Swedish Board for Technical Accreditation has accredited our laboratory for sensory and chemical analyses. Measurements are made under the auspices of a government agency and with the obligation to be impartial, making this the most stringent form of quality assurance. Most countries in the world accept test results that have been carried out at accredited laboratories and these can therefore be compared.

To ensure that our paperboard meets the demands for taint and odour neutrality, we regularly monitor production using organoleptic test procedures and our own fully trained assessment panel. We guarantee that our baseboard products Incada and Invercote register Robinson taint values according to EN1230 and DIN 10955 that are below the detection limit 0.6.

As an integral part of our product quality assurance policy, Iggesund Paperboard accepts responsibility for taint and odour problems proven to have been caused by our products.

Purity and hygiene

For end uses such as food, confectionery and pharmaceuticals, purity and hygiene are of critical importance. In order to maintain correct product performance Iggesund Paperboard only uses approved raw materials and additives, and carries out the production process according to good manufacturing practices that incorporate the use of risk assessment methods. Every chemical additive is assessed according to occupational health and safety, environmental impact and product safety before it is allowed to be used. Strömsbruk, supplying barrier-coated paperboard for many food end-uses, has a complete hygiene system in operation.

Product Labelling

Presently there are several labelling schemes on the market that claim to communicate representative facts about products´ performance and environmental acceptability (eco-labels). Iggesund Paperboard considers these schemes and labels too incomplete and subjective to provide a relevant assessment of paperboard products and their use. The international development of Environmental Product Declarations seems promising, but until these are developed and become an accepted standard, reference is made to the environmental fact sheets in Holmen and its World at

Product safety and liability

The essence of packaging is to ensure the quality, hygiene and safety of the packed product. To ensure these a number of national and international rules and regulations must be met. In addition, company and product specific measures are usually added. The final goal is to secure fitness for the intended use. It is important to protect the packed product against contamination from the outside and sometimes from direct contact with the paperboard surface. Iggesund Paperboard products are therefore made only from high quality primary fibres and functional additives which ensures safety, hygiene and good organoleptic properties. Where necessary additional barrier materials can be used to ensure that the quality of a packed product can be safely maintained until it is used.

In many countries, the consumer safety is protected by product liability legislation with far reaching consequences for the supply chain. In the event of damage all actors along the chain are responsible to the consumer (joint and several responsibility). The only exception is when you can prove, for your own area of responsibility, the fulfilment of the relevant requirements. A key consequence is thus to ensure the complete understanding and verification between supplier and customer of all the relevant aspects.

Product Safety Certificate

Iggesund Paperboard will on request issue a product declaration to verify the fitness and safety for the intended use. The document is issued after having carefully checked that the intended use of a specific paperboard product, under specified conditions of use, will not endanger the quality and safety of the packed product. The specific statements in the declaration are integral parts of the Iggesund Paperboard Management Systems. The given information is valid for two years or until further notice.

Present rules and regulations

For certain geographic areas or specific end-uses additional requirements must be met or barrier functions are needed. Iggesund Paperboard will ensure that the appropriate product/barrier combinations fulfil the requirements for the intended use. Barrier functions are generally achieved by plastic coating. The plastic itself, in all plastic coatings, meets the requirements of the EC Plastics Implementation Measure (PIM) Regulation 10/2011/EC and its amendments. For plastic coating/lamination only raw materials which are suitable for the specific application are used. The status in this respect is updated every year. Analysis of total migration tests are regularly made to verify compliance. All Invercote and Incada products are in compliance with the EU Regulation 1907/2006/EC (REACH) guaranteeing that the content of SVCH (Substances of Very High Concern) is lower than the stipulated limit of 0.1% in accordance with article 57 in the regulation.

All Iggesund Paperboard products will, subject to application/intended use, fulfil the requirements listed below.

In the absence of harmonised legislation Iggesund Paperboard ensures that its products fulfil the relevant requirements in the countries where the products are used. The main set of rules and regulations and their applicability to Iggesund Paperboard products are outlined in the tables on pages 14 and 15.

Good manufacturing practice

In the Commission Regulation (EC) No 2023/2006 of 22 December 2006 on good manufacturing practise for materials and articles intended to come into contact with food lays down rules on good manufacturing practice. The main requirement in this regulation is that we as a manufacturer shall operate an effective quality management of their manufacturing operations. For printing inks applied to the non-food contact side of a material or article GMP should in particular ensure that substances are not transferred into food by set-off or transfer through the substrate. When the board is used for fatty or aqueous packaging applications a barrier between the board and the packed foodstuff is required.

Used products and waste management

Producer responsibility consequences

The EU Directive on Packaging and Packaging Waste, EC94/62 and subsequent amendments, defines common requirements on packaging and packaging waste within the EU. However, the Directive’s formal implementation and interpretation and the practical methods introduced by the member countries vary widely. As a consequence the requirements and methods differ between countries. In some countries producer responsibility has been introduced and has led to industry-owned organisations which manage used packaging. In other countries there are community or nationwide schemes more or less controlled by the authorities. The result is systems with very different approaches to how packaging is taken care of and the costs involved. Each country has its own systems and rules.

Waste generated during the manufacture of Iggesund Paperboard’s products is managed and reported according the permits given by the local authorities

The EU Directive on Packaging and Packaging Waste (EC 94/62)

The EU Directive (EC94/62) is aimed at minimising the environmental impact of packaging and packaging waste. It places an obligation on prevention by source reduction, re-use or recovery of used packaging and minimisation of heavy metal contamination. The EU Commission gave the European Standards Organisation, CEN, a mandate to develop standards to be used as EU harmonised standards to ensure the fulfilment of the essential requirements. During 2004 CEN adopted and published the following standards: EN 13427:2004, EN 13428:2004, EN 13429:2004, EN 13430:2004 and EN 13431:2004. EN 13432:2000 was already published.

Iggesund Paperboard will act to meet all the relevant requirements of the directive, and will use the above mentioned CEN packaging standards to assess and document compliance with the essential requirements.

In general the following is valid for Iggesund Paperboard products:

EN 13427:2004 is called "the umbrella standard" which guides users through the texts, indicating which standards are applicable to each type of pack.

EN 13428:2004 consists of two parts which the first covers "prevention by source reduction", and the second "qualitative prevention by minimizing presence of noxious and hazardous substances in the packaging material".

  • In the areas of product development, marketing, sales and technical service, fitness for intended use is given priority to ensure that the main purposes and functions are fulfilled with a minimum of material. In the area of transport packaging the demand for prevention by source reduction is applicable and fulfilled by supplier requirements as defined in the standard.
  • All products meet the requirements regarding determination and minimisation of noxious and hazardous substances. EN 13429:2004 regarding reusable packaging is not applicable for our products.

Product design and composition is such that material recycling (EN 13430:2004) or energy recovery (EN 13431:2004) can be done without limitation. Our baseboards are intrinsically biodegradable. For the quantification regarding composting, tests should be made on the final packaging after the converting process (EN 13432:2000).

Black figures are best grown from green assets

Our approach to sustainability is one of care – for the environment, for our people and the people we come in contact with.

We also relate sustainability to business; both to our own and to our customers'.

We believe that black figures are best grown from green assets and that sustainability only can be approached with a long term perspective and a holistic view.
