Two promising new developments in bioplastics for packaging

Two promising new developments in bioplastics for packaging
Perstorp’s Capa improves the functional properties of bioplastics such as PLA, PHA and starch.

These two news stories point to the continued expansion of bioplastics in conventional and atypical ways including a material from Sweden that provides added functionality to polymer blends across a broad range of biopolymers and a second for a polyamide formulation for use in food packaging from chilled temperatures and up to 100°C.

PlasticsToday has reported on two news developments related to biopolymers late last week worth noting:

Perstorp, a specialty chemical company headquartered in Malmö, Sweden, is increasing its activities in bioplastics through Capa brand polycaprolactone (PCL), a biodegradable plastic that’s highly miscible, blends easily with other plastics, melts easily and is non-toxic. Biopolymers with Capa added are improved due to its good mechanical properties, biodegradability and compatibility across a wide range of polymers.

Capa (shown) improves the functional properties, especially toughness and flexibility, of bioplastics such as PLA, PHA and starch, enabling these to be competitive in film and packaging applications. Its compostability offers end-of-life benefits in packaging, bags and film applications.

Evonik’s bio-based polyamide PA1010 FDA-approved for food contact

Evonik Industries has announced that it has received FDA approval for a food contact substance notification (FCN) for its family of PA1010 polyamides. Its VESTAMID Terra DS16 natural may be used as a basic polymer in the production of articles intended for food contact. In summary, the material may be come in contact with all types of food at chilled to elevated room temperatures for single use, as well as all types of food in repeated use applications of temperatures to 100°C.
