WILMINGTON, Del., Aug. 31 -- DuPont (NYSE:DD) has announced commercial availability of DuPont(TM) Biomax(R) Strong, 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.

Biomax(R) 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(R) Strong additive meets requirements for compostibility.

The new additive expands DuPont Packaging's contribution to sustainable solutions in that it improves the performance of other sustainable offerings. DuPont is a world leader in the development and manufacturing of high- performance materials that provide environmentally sustainable solutions.

DuPont offers a complete line of high-performance polymers and additives to meet a wide range of packaging needs.
