WHAT IS BIO-BASED ACETATE? An eco-friendly and certified biodegradable alternative to traditional plastics, bio-acetate is formulated with natural, non-toxic, plasticisers and either a base of cotton or wood pulp fibres. Offering similar performance characteristics to conventional plastics, bio-acetates do not pose such a long-term toxic and physical hazard for land or sea life.
