Testing of soluble bio-digestible barriers for paper and board packaging
This whitepaper explores the considerations for process, product and environmental fate testing of soluble bio-digestible barriers for paper and board packaging. It was published in Published in Paper Technology International October 2021 and reproduced with their kind permission.
This new study commissioned by DS Smith and Aquapak shows that innovative, bio-digestible barrier coatings increase paper recycling rates and fibre yield, without compromising functionality, providing a viable new packaging alternative which is ready and available for use.
The independent research, ‘’Considerations for process, product and environmental fate testing of soluble bio-digestible barriers for paper and board packaging’, shows that new barrier technologies such as Hydropol provide an alternative to conventional plastic coatings used in paper packaging by promoting improved paper fibre separation and removing plastic waste from the recycling process, dramatically reducing the negative impact of paper packaging on the environment.
The work focused on Hydropol, a commercially available fully soluble, biodigestible barrier polymer, which can be adhesive or extrusion coated onto paper and brings a plurality of benefits to fibre-based packaging, including oil and grease resistance together with a high gas barrier.
