As an alternative to crude oil-based raw materials, bio-based materials are increasingly being used for the production of biaxially stretched packaging films – the most successful so far has been polylactic acid, PLA. Being discussed more and more are cellophane, bio-PE, PEF or PHA. Relevant points are always:
bio-based, renewable raw materials
reduction in consumption of fossil raw materials
biodegradability
starting point for many sustainable packaging solutions
