BOC are developing fiberbased, recyclable, ocean biodegradable closures. Simply said, paper screwcaps.
First generation are based on top (not cone) seal. Here we have developed a ocean biodegradable liner that, we think, could also be used for crown. The liner is a variant of PHA, low weight and ocean biodegradable. It has ok oxygen and water vapour barrier.
Production of the base material has been developed from side streems of Swedish forest industry waters with Karlstad university and research institutes of Sweeden but can also use already commersial raw materials.
The raw material today is significantly more expensive than standard polymers ($4-5/kg) and therefor lends itself to applications where small amounts are used.
We have not tested crown solutions but flat top screw on solutions.
The liner is a additional value from Blue Ocean Closures as the core of the production model are set up around the screw-caps. Any developed will however strengthen the concept and create adit...
