Compostable resin takes the deep freeze

A polylactic acid-based polymer (PLA), CP-INJ-13, offers biodegradability during composting of what is claimed to be the first-ever such bioresin that is freeze-tolerant. The material is said to retain structural rigidity in freezing temperatures as low as –35°C for frozen food applications such as injection molded ice cream containers. The producer says it features good flexibility compared to other PLA-based products, tensile elongation that is about 10-times greater than conventional PLA grades, and a notched IZOD impact measurement of 2.5 lb-ft/in.

It is certified as biodegradable and compostable in both the U.S. and Europe according to Biodegradable Products Institute, ASTM, and European Bioplastics (EN) standards.
