DuPont announced commercial availability of a petrochemical additive that increases the utility of bio-based, biodegradable polylactic acid (PLA) packaging.
PLA has held appeal within the packaging industry because it is biodegradable when composted industrially. It is considered a sustainable alternative to conventional plastics since 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.
The new product 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 this additive meets requirements for compostibility.
