Abstract

material para tampa de lata resistente à fissura. a presente invenção refere-se a material para tampa de lata de alumínio (ces) e aos métodos para produzir ces. a ces inclui uma tira metálica laminada que tem um revestimento de película polimérica e que exibe beneficamente resistência à fissura. em alguns casos, a ces resistente à fissura aqui descrita também apresenta baixo empenamento e alta resistência à abrasão. a tira metálica laminada pode incluir o revestimento de polímero laminado em um lado voltado para o interior da tira metálica. a tira metálica laminada pode incluir ainda um revestimento de pré-tratamento entre o revestimento de película polimérica e a tira metálica. a ces é formada pela laminação de uma película polimérica em um lado da tira metálica e pelo recozimento da tira metálica laminada. em alguns casos, a película polimérica laminada à tira metálica é uma película de tereftalato de polietileno (pet).
