By using grease resistant board coatings and PEFC sustainably sourced cellulose for windows, the company eliminates the need for plastic coatings and laminates.
The cellulose used is made from wood sourced from sustainably managed woodland, and carries the Vincotte OK Home compost accreditation, EN13432.
“We have achieved less than 5% bioplastic, meaning these packs are future proof in regards to recyclability and if too contaminated with food waste can be composted where facilities exist,” said Kate Berry, head, marketing & products, Colpac.
The 5% bioplastic content importantly is well within the OPRL guidelines published in January 2020.
Zest Heat Seal packaging will still be recyclable when the aspirational 5% plastic content comes into effect, extending its appeal internationally where some countries have already set the 5% goal.
The window can be easily removed should a consumer wish to compost it as it is both commercially compostable to E13432 and home compostable.
The Zest Heat Seal range also helps to tackle the major issue of food waste as it seals the pack and so extends food shelf life by two or three days.
WRAP chief executive, Marcus Gover, recently announced that the average family annually wastes £700 of worth of food – equating to 4.5 million tonnes, and Wrap have also declared that by extending product shelf life by just one day could save 250,000 tonnes of this waste.
