Abstract
Patente de Invenção: <B>"PELìCULA DE POLIETILENO DE MéDIA DENSIDADE COM DILACERAMENTO UNIDIRECIONAL"<D>. A presente invenção refere-se a películas poliméricas biaxialmente orientadas. De modo específico, a presente invenção refere-se a películas de polietileno biaxialmente orientadas, tendo características de rasgamento unidirecional na direção da máquina e métodos destes. A película da presente invenção compreende (1) uma camada interna de polietileno de média densidade (MDPE), e, opcionalmente um agente de cavitação, (2) pelo menos uma camada superficial em pelo menos uma superfície da camada interna. As camadas interna e superficial são aderidas co-extensivamente umas às outras e biaxialmente orientadas na direção, tanto da máquina, como transversal.
