Considerations for process, product and environmental fate testing of soluble bio-digestible barriers for paper and board packaging

WHITE PAPER

This whitepaper explores how innovative, bio-digestible barrier coatings can increase paper recycling rates and fibre yield, without compromising functionality thus providing a viable new packaging alternative which is ready and available for use.

PITA (Paper International Technology Association) originally published this study commissioned by DS Smith and Aquapak. The results obtained in the study provide packaging designers with a clear route as to how to meet the Paperbased Packaging Recyclability Guideline set out by the European association representing the paper industry (Cepi), and which are there to:

  1. Ensure that the paper fraction of the packaging breaks down into single fibres when pulped within a specified timeframe
  2. Give preference to polymers and other sealing agents that can be dealt with efficiently by the papermill process and effluent treatment systems and do not compromise the finished product, the production process or the environment whilst being recycled.
