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 2):
The container of  claim 1  which further comprises (c) a second multilayer film about 5 \u03bcm to about 75 \u03bcm thick and affixed to a second side of the metal sheet, in which the second multilayer film comprises a second base layer and a second skin layer coextensively adjacent and in direct contact with a side of the second base layer, in which at least 70 wt % of the second base layer and the second skin layer each independently consists of PET, the PET of the second 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 second multilayer film is positioned such that a side of the second base layer opposite the second skin layer is in direct contact with the second side of the metal sheet.
