Abstract

See full text

Films and formulations that include recycled polylactic acid resin are described. The films and formulations include, for example, 1-10 wt% of an ethylene-acrylate copolymer. The use of the ethylene-acrylate compolymer in the polylactic acid formulations allows for recycling of PLA-based films and articles with minimum degradation, as exhibited by changes in intrinsic viscosity and color properties.
