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 low feathering, low hairing, and high abrasion resistance. The laminated metal strip can include the laminated polymer coating on an exterior-facing side and a lacquered coating on an interior-facing side. 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, which may be colored.
