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.
