Bio-Flex® F2131

Bio-Flex® F2131 by FKur is a biodegradable polymer-blend based on polylactic acid (PLA), contains a copolyester and additives. It is derived from natural resource material but does not contain any starch or starch derivatives. The PLA used for the production of BIO-FLEX® is supplied by NatureWorks. Possesses high breathability and wide processing window. It is processable on standard extrusion machinery with a high throughput and is printable without corona treatment. Can easily be colored with masterbatches based on PLA. Bio-Flex® F2131 is a stiffer version of Bio-Flex® F1130 with nearly the same touch but with a tendency towards a "paper-like" feel. Used for mono and co-extrusion films. Suitable for waste bags.
