Cereplast, Inc. (OTCBB: CERP), manufacturer of proprietary, bio-based, sustainable plastics, extended the range of applications for biodegradable, compostable plastic with the introduction of the first-ever freeze-tolerant resin, CP-INJ-13. The newest addition to the Cereplast Compostables resin family retains structural rigidity in freezing temperatures, ideal for frozen food applications, such as ice cream containers, and all applications requiring resistance to low temperature and/or high flexibility.

The new polylactic acid (PLA)-based resin exhibits superior flexibility compared to other PLA-based products, allowing it to withstand sub-zero environments. CP-INJ-13 provides structural integrity in temperatures as low as -35 C, compared to about 20 C for standard PLA-based plastic. In addition, tensile elongation is approximately 10x greater (284 per cent for CP-INJ-13 and typical 25 per cent or less for neat PLA as measured by ASTM D638) and the notched IZOD impact measures 2.5 lb-ft/in. at 23 C compared with 0.5 lb-ft/in with traditional PLA-based plastic.

“The new addition to our product lineup is a direct result of customer demand for freeze-capable bioplastic products,” said William Kelly, Cereplast Senior Vice President, Technology. “We are constantly working with our customers to find solutions to their needs, and therefore expanding the applications of biodegradable, compostable plastic.”

Cereplast Compostables resins are renewable, ecologically sound substitutes for petroleum-based plastic products, replacing nearly 100 per cent of the petroleum-based additives used in traditional plastics. Cereplast Compostables resins are starch-based, made from corn, wheat, tapioca and potato starches.

All Cereplast Compostables resins are certified as biodegradable and compostable in the United States and Europe, meeting BPI (Biodegradable Products Institute) standards for compostability (ASTM 6400 D99 and ASTM 6868), and European Bioplastics standards (EN 13432).
