Abstract:
A composite includes a multilayer polyethylene terephthalate (PET) film having a base layer and an adjacent skin layer. The PET of the skin layer has inherent viscosity of about 0.70-0.90 and carboxyl endgroup concentration of less than 25 eq/T. The base layer can be affixed to a thin metal sheet. Optionally, the base layer of a second multilayer PET film with a skin layer inherent viscosity of about 0.70-0.90 and carboxyl endgroup concentration of less than 25 eq/T can be affixed to the opposite side of the metal sheet. The composite is suited for making food and chemical containers such as food storage cans that resist blush discoloration from steam contact during container formation and age degradation during extended storage of harsh chemical products.

Claim (Index 6):
A method of packaging a product in a container, comprising the steps of:\n (I) providing a layered composite comprising\n (a) a two-sided, metal sheet about 50 \u03bcm to about 1300 \u03bcm thick, \n (b) a first multilayer film about 5 \u03bcm to about 75 \u03bcm thick disposed on one side of the metal sheet, and optionally, \n (c) a second multilayer film about 5 \u03bcm to about 75 \u03bcm thick and disposed on the second side of the metal sheet, \n in which at least one of the first multilayer film and the second multilayer film each independently comprises a base layer and a skin layer coextensively adjacent and in direct contact with a side of the base layer, in which at least 70 wt % of the base layer and the skin layer each independently consists of polyethylene terephthalate (PET), the PET of the skin layer having intrinsic viscosity in the range of about 0.70 to about 0.90 and carboxyl end group concentration less than about 25 eq/T, and in which the first multilayer film and the second multilayer film are affixed to the metal sheet positioned such that a side of the base layer opposite the skin layer is in direct contact respectively with the first side and the second side of the metal sheet,\n (II) fabricating a container having a wall comprising the layered composite, \n (III) placing the product in the container, and \n (IV) sealing the container.
