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.

摘要： A multi-layer packaging film comprising a bio-based layer and method for making the same. An outer layer comprising a bio-based film is adhered to a product side layer comprising a bio-based film having barrier properties. A non-compostable sealant layer is pattern applied to a portion of the product side layer. Because a portion of the bio-based product side layer is exposed, upon opening of the package the product side layer is susceptible to moisture. This allows for subsequent biodegradation or compostability of the films. In another embodiment the sealant layer comprises a water permeable material. Upon opening of the package moisture can subsequently contact the product side layer and initiate biodegradation.
