Can end formed from laminated metal sheet

A laminate and a process for making a laminate of aluminum or aluminum alloy and a polyester. The process includes forming a laminate by contacting an aluminum or aluminum alloy sheet or foil with a film of polyester at a temperature and pressure sufficient to adhere the film to the sheet or foil, reheating the laminate to a temperature above the crystalline melting point of the polyester, cooling the laminate at a cooling rate controlled to prevent crystallization of the polyester, and quenching in water such that the molecular weight of the polyester layers in the laminate is between 14,000 and 23,000.

Laminates of metal and polyester film

A laminated metal sheet, the metal sheet having adhered on at least one major surface thereof a film of a non-crystalline polyester, and a process for the preparation thereof. The laminated metal sheet is particularly useful for forming into drawn and wall ironed (DWI) cans. The laminate is also useful for forming other non-retorted packaging components.
