Patent number: 11027523Abstract: 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.Type: GrantFiled: July 28, 2017Date of Patent: June 8, 2021Assignee: TORAY PLASTICS (AMERICA), INC.Inventors: Jan Moritz, Pat Andrews, Keunsuk P.

Patent number: 10596794Abstract: A carrier film of thermoplastic polyester has releasable metal adhesive properties suitable for a metal transfer in which the polyester film is metalized and the metal layer is subsequently transferred to a permanent adhesive-coated substrate. The metal layer is in direct contact with the polyester carrier film and no intermediate release layer is present. Desired metal adhesion is provided by dispersing an suitable surfactant, and optionally, a hydrocarbon wax, uniformly into the polyester film. Surfactant on the outer surface of the carrier film modifies metal adhesion to the polyester such that the metal can be removed in a metal transfer operation.Type: GrantFiled: January 19, 2018Date of Patent: March 24, 2020Assignee: Toray Plastics (America), Inc.Inventor: Jan Moritz
