New Technology to Help Boost PLA Resistance

8 September 2010

A new study has found a modifier that can raise bioplastic's heat-deflection temperature by at least 50°F, helping to expand the sphere of packaging applications.

Researchers at Agricultural Research Service (ARS), US, say they have devised a temperature deflection modifying mechanism that boosts heat resistance properties of bioplastic polylactic acid (PLA).

The modifier is more than 90% corn based and fully biodegradable, the team said.

The modifier will help the PLA, which could be used for food and beverage containers that are based on hot-filling technology, the team said.

Normal corn-based plastics have a lower heat tolerance than petroleum-based plastics, which exclude it from being used for packaging applications, according to foodproductiondaily.com.
