With oil prices high, compostable polylactic acid (PLA) from NatureWorks LLC in Minnetonka, Minn., doesn't look so expensive anymore. And foaming could reduce its cost even further. An Italian packaging company has launched the first foamed PLA trays for fresh carry-out foods like meat, fish, cheese, fruit, and prepared foods. Coopbox Europe SpA in Reggio, Emilia, won the 2005 Packaging Award from the Italian Packaging Institute for its Naturalbox thermoformed trays. The sheet is made on a standard tandem foam extruder using CO2 to reduce PLA's density by 68% from 1.25 g/cc to 0.40 g/cc. NatureWorks is now working with North American customers on foamed PLA trays.
