Abstract

IENTADAS"<D>. A invenção é uma película de multicamadas orientadas compreendendo pelo menos uma camada externa, constituído de 50 a 100% em peso da dita camada externa de um copolímero de etileno tendo uma densidade de 0,900-0,935 g/cm³ e umn CDBI de 50-95% da dita camada externa estando em contato com uma camada de núcleo de polipropileno, e a dita película tendo sido preparada pela coextrusão do dito copolímero de etileno e a dita camada de polextrudadas podem ser uniaxial e biaxialmente orientadas no equipamento estirador sem dificuldades, levadas pela presença de frações de polímero amorfo de baixo peso molecular inerentemente presentes no polietileno de baixa densidade linear de Zieglerculas de polietileno biazialmente orientadas podem ser retiradas, enquanto a temperatura de vedação é abaixada e a resistência da vedação a quente e ao aperfeiçoadas.
