Abstract

estrutura de múltiplas camadas, saqueta que fica em pé, e, métodos para formar uma estrutura de múltiplas camadas e uma saqueta que fica em pé. uma estrutura de múltiplas camadas pode incluir uma película polimérica à base de polietileno que compreende: uma camada de vedação; pelo menos uma camada intermediária; e uma camada de impressão; e uma camada externa de ultravioleta ou tinta curável por feixe de elétrons ou verniz curado na camada de impressão do substrato polimérico à base de polietileno, em que a estrutura de múltiplas camadas tem uma resistência de superfície térmica de modo que quando as barras de vedação são aplicadas ao película polimérico à base de polietileno em ciclos de vedação não superiores a 2 segundos e a uma temperatura correspondente à temperatura de fusão do polietileno, as barras de vedação permanecem sem polímero.
