Abstract

"PROCESSOS PARA BIAXIALMENTE ESTIRAR UMA PELìCULA POLIMéRICA E UMA PELìCULA DE POLIPROPILENO, PELìCULA, E, FITA". Um processo para biaxialmente estirar uma película polimérica juntamente com uma sobrepolarização do perfil de estiramento. O processo compreende as etapas de: a) transmitir uma temperatura suficientemente elevada à película para permitir uma quantidade significativa de estiramento biaxial; e b) esticador biaxial estirando a película até um parâmetro final de estiramento da primeira direção e um parâmetro final de estiramento da segunda direção, em que pelo menos 75% do parâmetro final de estiramento da primeira direção é alcançado antes que não mais do que 50% do parâmetro final de estiramento da segunda direção seja alcançado, e em que o parâmetro final de estiramento da primeira direção não seja maior do que o parâmetro final de estiramento da segunda direção. Um processo alternativo compreende um processo para biaxialmente estirar uma película polimérica juntamente com uma sobrepolarização do perfil de estiramento. O processo compreendendo as etapas de: a) transmitir uma temperatura suficientemente elevada à película para permitir uma quantidade significativa de estiramento biaxial; e b) esticador biaxial estirando a película de acordo com um perfil de estiramento até um parâmetro final de estiramento da primeira direção e um parâmetro final de estiramento da segunda direção, em que o parâmetro final de estiramento da primeira direção não é maior do que o parâmetro final de estiramento da segunda direção. Em um tal processo: i) uma linha de estiramento entre o ponto que define o parâmetro zero de estiramento e o ponto que define os parâmetros finais de estiramento da primeira e segunda direção representa um perfil de estiramento proporcional e define uma área de estiramento proporcional; e ii) a curva que representa o perfil de estiramento entre o ponto que define o parâmetro de estiramento zero e o ponto que define os parâmetros finais de estiramento da primeira e segunda direção define uma área de pelo menos 1,4 vezes a área de estiramento proporcional.
