Cereplast Inc. has developed a higher-temperature-resistant bioplastic in its Compostables lineup.
CP-TH-6000 is a thermoforming resin able to withstand 155° F, compared with a maximum 140° F resistance typical for biodegradable and compostable resins, according to the Hawthorne, Calif., company. Based on polylactic acid, the new material relies on nanotechnology and proprietary processes to achieve its temperature rating.
CP-TH-6000 also is fully compostable, meeting the ASTM 6400 standard, according to Cereplast. Also, it is marketed at a lower price than conventional thermoformable polystyrene grades.
