A new additive adds strength to polylactic acid

A new additive that broadens the usability of polylactic (PLA) has been introduced by Rohm and Haas. The new additive Paraloid BPM-500, uses dispersible nanoparticles that do not scatter light, and allows for the production of PLA packaging material that exhibits less than 10% haze at 5% loading. Visual transparency is maintained along with stronger impact and tear-resistance. Paraloid BPM-500 complies with food contact requirements in Europe and with room temperature food contact requirements in the US.
