Crazing resistant can end stock

Abstract

Provided herein are an aluminum can end stock (CES) and methods for producing CES. The CES includes a laminated metal strip having a polymer film coating and beneficially exhibiting crazing resistance. In some cases, the crazing-resistant CES described herein also exhibit low feathering and high abrasion resistance. The laminated metal strip can include the laminated polymer coating on an interior-facing side of the metal strip. The laminated metal strip can further include a pretreatment coating between the polymer film coating and the metal strip. The CES is formed by laminating a polymer film to a side of the metal strip and annealing the laminated metal strip. In some cases, the polymer film laminated to the metal strip is a polyethylene terephthalate (PET) film.
