Additives for Biopolymers

From compostable packaging to biodegradable plastic cutlery, biopolymers are on the rise. The only limits are technical performance and processability. VINNEX® are poly(vinyl acetate) based additives which allow the combination of several biopolymers and therefore improve performance and processing. With VINNEX®, biopolymers can be processed just like standard thermoplastics. The system makes materials such as starch, polylactic acid (PLA), polyhydroxyalkanoates (PHA), polybutylene succinate (PBS) or cellulose acetate (CA) compatible with each other. This makes it possible to precisely adjust physical properties as required. The biodegradability of the biopolymers blends is maintained. In addition, most VINNEX® grades are suitable for use in food-contact applications.
