摘要：
Embodiments herein relates to a Bisphenol A-free multi-layer biaxially oriented polyester (BOPET) film. The BOPET film has a release layer, which aids in the release of food. The BOPET film can be laminated to metals used in the manufacture of food containers with the outer release layer being exposed to allow a direct food contact between the surface of the outer release layer and food. More particularly, the invention relates to a novel outer release layer resin composition comprising an ultra-high molecular weight siloxane polymer and a polyethylene trephthalate resin; and an alkali-metal phosphate and a phosphoric acid compound added, during polymerization of the outer release layer resin composition, as a catalyst/additive package to the ingredients forming the outer release layer resin composition. A wax component is added in the outer release layer, for more robust release performance.
