A new ethylene copolymer is said to improve the toughness and reduce the brittleness of biodegradable polylactic acid (PLA) packaging. Biomax Strong from DuPont Packaging, Wilmington, Del., increases the impact strength, flexibility, and melt stability of PLA, particularly in rigid molded and thermoformed parts. At loadings of 1% to 5%, the additive is said to outperform competitive toughening products with minimal effect on transparency and no loss of compostability. The first grade, Biomax Strong 100, is available for non-food uses. A second grade, Biomax Strong 120, will be available in three to six months for food-contact applications.
