Abstract

''MéTODO PARA BIAXIALMENTE ESTIRAR UMA PELìCULA POLIMéRICA E UMA PELìCULA DE POLIPROPILENO, PELìCULA, E, FITA'' Um método de biaxialmente estirar uma película polimérica de acordo com um perfil de estiramento de sobrestiramento a um parâmetro de estiramento final de primeira direção e um parâmetro de estiramento na segunda direção final. O método compreendendo as etapas de: a) conferir uma temperatura suficientemente alta à película, para permitir um grau significativo de estiramento biaxial; b) estirar em esticador biaxial a película a um parâmetro de estiramento de primeira direção pico (48) que é pelo menos 1,2 vezes o parâmetro final de estiramento de primeira de direção (14), em que o parâmetro final de estiramento de primeira direção não é maior do que o parâmetro de estiramento na segunda direção final; e c) subseq³ente à etapa (b), retrair a película da primeira direção para o parâmetro final de estiramento de primeira direção.
