Abstract

"ESTRUTURAS DE PELìCULA POLIMéRICA PARA USO COMO SACOS ENCOLHìVEIS". A invenção refere-se a películas de encolhimento a quente, tendo uma mistura de cloreto de polivinilideno e acrilato metílico como camada barreira. Especificamente, esta invenção refere-se a estruturas de película tendo uma primeira camada-barreira composta de uma mistura de cloreto de polivinilideno e acril ato metílico, em que a referida camada barreira tem duas superfícies opostas; uma segunda camada que adere a uma das superfícies da primeira camada barreira, composta de uma mistura de copolímeros de etileno e acetato de vinila; uma terceira camada que adere à outra superfície da primeira camada barreira, composta de uma mistura de copolímeros de etileno e acetato de vinila; uma quarta camada que adere a uma das referidas segunda ou terceira camadas, composta de uma mistura de copolímeros de etileno e acetato em que os índices de fusão das referidas misturas das referidas segunda, terceira e quarta camadas são os mesmos; uma quinta camada que adere à outra das referidas segunda ou terceira camadas, composta de uma mistura de polietileno linear de baixa densidade e polietileno de baixa densidade. As referidas estruturas de película têm utilidade como sacos encolhíveis. A referida estrutura de película é orientada e pode, opcionalmente, ser irradiada.
