Symphony Environmental, a British developer of oxo-biodegradable plastics, claims to have achieved a world breakthrough with the first degradable, aluminium-coated multi-layered plastic packaging film, based on its d2w oxo-biodegradable additive.
Mexican snack food firm Barcel has adopted the film, which is based on Symphony's d2w oxy-biodegradable additive, for its Takis potato crisps that are distributed across Latin America.
Aluminium-coated film is used to maintain freshness and extend product life, but Symphony said that complete degradation was previously impossible.
The film combines three separate layers of d2w-treated plastic – two exterior layers of polypropylene and a polyethylene inside layer that acts as a bond. The fine aluminium coating will break down alongside the plastic and join the existing aluminium in the environment, Symphony said.
Barcel is a subsidiary of Bimbo Bakeries which appointed Symphony as its supplier of oxy-biodegradable additive supplier last year.
Symphony chief executive Michael Laurier described the aluminium-coated film as a major achievement for the firm.: - I am delighted to be able to announce this launch with Barcel, which is evidence of the excellent work that we have been doing with Bimbo. Bimbo has led the way in adopting degradable packaging in Latin America and this development will further strengthen the d2w brand on a Global scale. We look forward to working with Bimbo on further developments and also to sharing a successful future in the use of d2w eco-compatible products in many markets and applications.
