Consortium launches PLA-based barrier films


In Spain, packaging maker Coexpan has partnered with bioplastic producer NatureWorks and Italian manufacturer of extrusion and thermoforming lines AMUT Group to develop biobased polylactic acid sheets for barrier packaging applications.

Coexpan says the PLA rigid sheets—dubbed CoexBioR—come in medium and high-barrier ranges and are suitable for dairy desserts, coffee and tea capsules, and fresh food trays. The sheets reduce oxygen, grease and water vapor transmission, all of which preserves food flavors.

The companies will be featuring demonstrations of COEXPAN’s PLA sheets at upcoming Chinaplas and K-show exhibitions.
