摘要： A multi-layer PLA film with barrier properties having one or more additives. In one aspect the additive can lower the glass transition temperature of the PLA to enhance the span of environments in which the PLA film can degrade. In one aspect, a plasticizer can be added to lower the glass transition temperature to facilitate degradation at lower temperatures. In one aspect, calcium carbonate can be added to a PLA film layer.
