Abstract:
This invention provides an economical process for extruding a PLA resin into a low density foam with a high closed cell content. Excellent quality, low density foam is produced easily and reproducibly. The PLA resin in the foam has a weight average molecular weight of at least 500,000 and an intrinsic viscosity of at least 1.4 deciliters/gram.
