A proprietary impact modifier is said to toughen PLA (polylactic acid) biopolymer without sacrificing clarity. Newly available from Rohm and Haas Corp., Philadelphia, Paraloid BMP-500 was developed to support the packaging industry's move toward renewable resources. According to Rohm and Haas, growth of PLA has been hampered because it is somewhat weaker and more brittle than standard materials. Previous attempts to strengthen PLA packaging reportedly have sacrificed transparency. BMP-500 utilizes dispersible nanoparticles that do not scatter light, allowing for production of PLA packaging that exhibits less than 10% haze at 5% additive loading, combined with greater impact and tear resistance. The additive also complies with food-contact requirements in Europe and with room-temperature food-contact requirements in the U.S. Tel: (215) 592-3000 . www.rohmhaas.com
