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 3):
The container of  claim 2  in which the base layer of the first multilayer film comprises an adhesion layer about 0.1 \u03bcm to about 5 \u03bcm thick and a core layer, in which the adhesion layer is on the side of the base layer opposite the skin layer and consists essentially of a blend of about 2-19 wt % amorphous polyester copolymer and a complementary amount to total 100 wt % of PET.
