  • Publication number: 20170326842
    Abstract: Embodiments herein relates to a Bisphenol A-free multi-layer biaxially oriented polyester (BOPET) film, for lamination on metal sheets, which could be used for food containers. The BOPET film has at least one outer release layer, which aids in the release of food, such as a high protein food source, when food is cooked and sterilized in direct contact with the outer release layer. 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.

  • Publication number: 20160183544
    Abstract: An embodiment relates to a multi-layer, biaxially oriented polyester (BOPET) film comprising a food contact substance, wherein the BOPET has a percent release in a retort test after can lamination such that substantially all food contacting the BOPET during the retort test is released. Another embodiment relates to a method comprising applying a food contact material comprising a food contact substance to a multi-layer, biaxially oriented polyester (BOPET) film, wherein the food contact material is prepared at around room temperature without heating.
