Patent number: 9561886Abstract: Multi-layer films suitable as sealable or peelable sheet that can be used for closing foodstuff containers are described. These multi-layer films includes a polymeric substrate layer and a seal or a peel-seal layer. The multilayer composite film preferably includes four component layers, namely in order, a polymeric base layer for mechanical strength, a thin organic barrier layer, an ethylene polymer-based adhesive layer, and a heat seal layer including an ethylene copolymer, such as ethylene vinyl acetate copolymer. The film is useful as a peelable heat sealable lid for containers of diverse polymer compositions storing various products such as foodstuffs and pharmaceuticals.Type: GrantFiled: September 13, 2012Date of Patent: February 7, 2017Assignee: TORAY PLASTICS (AMERICA), INC.Inventors: Tracy A.

Publication number: 20140329015Abstract: Described are antifog films useful for packaging food, and more particularly to antifog films that can be used as lidding films in trays made of amorphous polyester. The films may include at least one base layer or film, such as a polyester film, and a heat seal layer. The antifog layer is coated on the heat seal layer. The heat seal layer allows the antifog coating to more strongly adhere to the antifog film. The heat seal layer may be an amorphous polyester layer.Type: ApplicationFiled: June 9, 2014Publication date: November 6, 2014Inventors: Jon Ian MONTCRIEFF, Roberto SIU
