Cornstarch PLA

Compostable plastic made from renewable biomass and a synthetic binding agent.

Description


PLA is a bioplastic derived from renewable biomass, typically from fermented plant starch from corn, cassava, sugarcane or sugar beet pulp. When combined with PBAT (a fossil fuel derivative) it becomes strong and flexible enough to be used as a film for packaging applications.

Challenges


The shelf life of the cornstarch-based film is approximately nine months, and must be stored in a dark, dry place. The bags also use PBAT, a fossil fuel derivative, as a binding agent for more flexibility. Although derived from fossil fuels, PBAT is still compostable.
