Abstract

"PELìCULAS EM MULTICAMADAS TUBULARES, MéTODO E APARELHAGEM PARA PREPARAR AS MESMAS". Uma película em multicamadas tubular compreende uma camada-barreira central e um par de camadas adesivas em lados opostos da camada-barreira central. As camadas adesivas cobrem completamente a camada-barreira central. As bordas opostas da camada-barreira central recobrem longitudinalmente toda a extensão da película em multicamadas tubular. A espessura total da camada-barreira central na porção recoberta é substancialmente igual à espessura da camada-barreira central na porção não recoberta. A película em multicamadas tubular inclui também camadas superficiais interna e externa. A camada superficial interna estende-se completamente em torno do interior da película em multicamadas tubular, e a camada superficial externa estende-se completamente em torno do exterior da película em multicamadas tubular.
