Abstract:
A laminate includes the following substantially coextensive layers in the following order: (a) a non-sealable, self-supporting, thermoformable copolyester film layer having a first surface and a second surface, the second surface constituting an outermost, exposed surface of the laminate; (b) a laminating adhesive layer on the first surface of the thermoformable copolyester film layer; and (c) a self-supporting, thermoformable structural film layer having a first surface and a second surface, the first surface contacting the laminating adhesive layer. Polyethylene terephthalate constitutes at least 80% by weight of the self-supporting thermoformable copolyester film layer; the thermoformable structural film layer includes a polymer selected from the group consisting of polyamides, polypropylene, polyethylene, polyethylene terephthalate, ionomers, ethylene acrylic acid copolymers, ethylene vinyl acetate copolymers, polystyrene, ethylene vinyl alcohol copolymers and polyvinylidene chloride; the thermoformable copolyester film layer, the structural film layer and the laminate each shrink less than 5% in length and width upon exposure to boiling water for five seconds; and the laminate is thermoformable and its chloroform-soluble extractives meet the requirements of paragraph h(1) of 21 CFR § 177.1630 as defined herein.

Claim (Index 10):
A package comprising:\n a) a laminate thermoformed in a shape of a receptacle having a pocket with a flange and an opening, wherein the laminate comprises the following substantially coextensive layers in the following order:\n i) a self-supporting, biaxially oriented thermoformable copolyester film layer having a first surface and a second surface, said second surface constituting an outermost, exposed surface of the laminate and forming an inner surface of the pocket and a mating surface of the flange, wherein the copolyester in the thermoformable copolyester film layer comprises from 90 mol % to 97 mol % of at least one aromatic dicarboxylic acid and correspondingly from 10 mol % to 3 mol % of at least one aliphatic dicarboxylic acid; \n ii) a laminating adhesive layer on the first surface of the thermoformable copolyester film layer; and \n iii) a self-supporting, thermoformable structural film layer having a first surface and a second surface, said first surface contacting the laminating adhesive layer; \n wherein:\n polyethylene terephthalate constitutes at least 80% by weight of the self-supporting biaxially oriented thermoformable copolyester film layer, \n the thermoformable structural film layer comprises a polymer selected from the group consisting of polyamides, polypropylene, polyethylene, polyethylene terephthalate, ionomers, ethylene acrylic acid copolymers, ethylene vinyl acetate copolymers, polystyrene, ethylene vinyl alcohol copolymers and polyvinylidene chloride, \n the thermoformable copolyester film layer, the structural film layer and the laminate each shrink less than 5% in length and width upon exposure to boiling water at atmospheric pressure for five seconds; and \n \n b) a heat-sealable film, wherein the opening of the receptacle is closed by the heat-sealable film, said heat-sealable film comprising a self-supporting polymeric film having on a surface thereof a substantially coextensive heat-seal layer; wherein the heat-seal layer of the heat-sealable film is in contact with and bonded to the mating surface of the flange of the thermoformed receptacle; and wherein chloroform-soluble extractives of the laminate and the heat-sealable film meet the requirements of paragraph h(1) of 21 CFR \u00a7 177.1630 as defined herein.
