Iggesund Paperboard grades

Solid Bleached Board (SBB, GZ) multiply construction

SBB is made exclusively from bleached chemical pulp.

It usually has a pigment coated top surface and can also be pigment coated on the back.

Folding Box Board (FBB, GC1), white back, multiply construction

FBB, white back, is made from layers of mechanical pulp sandwiched between layers of bleached chemical pulp.

The top layer is pigment coated. The back is thicker than FBB, cream back, and can also be pigment coated.

Folding Box Board (FBB, GC2), cream back, multiply construction

FBB, cream back, is made from layers of mechanical pulp sandwiched between layers of bleached chemical pulp.

Test methods

General

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

  • Paperboard property tests
  • 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, 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.
