Biomax Strong, a petrochemical additive that increases the utility of bio based, biodegradable polylactic acid (PLA) packaging, is now commercial availability from DuPont.
PLA has appeal within the packaging industry because it is biodegradable when composted industrially. It is considered a sustainable alternative to conventional plastics, as it is derived from fermentation of agricultural by products. However, adoption has been hindered by performance deficiencies compared to conventional plastics, including brittleness and decreased durability.
DuPont says Biomax Strong helps address these issues by providing improved toughness. Compared to other tougheners, it enables improved transparency of the final containers made from PLA – an important consideration for packaging appeal. PLA made with the Biomax Strong additive meets requirements for compostibility, the company confirms.
