Product description

The bio coating is based on renewable resources and adapted for organic recovery through composting or anaerobic digestion. Combined with a selected number of Invercote grades, the material is suitable for packaging applications where biodegradability is desired. Both the baseboard and the coating conforms to the European Norm regarding compostability, EN 13432. The product also works well in existing packaging recycling systems.

Invercote Bio is particularly suitable as an alternative to PE as a barrier against grease and liquids, e.g. ice cream, cups for cold drinks and chilled food. The converting properties, such as die-cutting, heat sealing and creasing are comparable to those of PE, though its tensile strength is higher.

Additional properties

The Bio coating gives:

  • Heat sealing
  • Gluing
  • Fat barrier
  • Liquid water barrier from the inside
  • Neutral from a taint and odour perspective

The reverse side always has a glossy finish for improved surface and barrier characteristics.

An environmental choice of material

When the Swedish retail chain Coop decided to create new packaging for its own-brand frozen berries, it deliberately chose a higher-priced base material for environmental reasons.

Coop selected the paperboard material Invercote Bio, a virgin-fibre-based board coated with bioplastic.
