Described are methods for recycling biaxially oriented thermoplastic crystallizable films, such as polyester terephthalate (PET) films, that have been coated with various polymers or waxes that are immiscible in the primary molten thermoplastic. The resultant processed recycle can be used to make new biaxially oriented thermoplastic films while avoiding process instability and optical defects in the finished film associated with immiscible polymeric and/or wax coatings. |
