Abstract

"FILME POLIMéRICO TERMICAMENTE VEDáVEL, LAMINADO TERMICAMENTE VEDADO, E, EMBALAGEM TERMICAMENTE VEDADA". Filmes poliméricos vedáveis (A) tendo uma camada de vedação térmica externa (1) com uma viscosidade em suas temperaturas de vedação térmica, tal que ela irá fluir ao interior de espaços intersticiais entre as fibras de um material fibroso (B) e encapsular as fibras em tais temperaturas, uma camada polimérica intermediária (2) em contato com a camada de vedação térmica, a camada polimérica intermediária sendo capaz de se dividir coesivamente quando o filme termicamente vedado é destacado, e pelo menos uma camada polimérica adicional (3), a camada de vedação térmica sendo mais fácil de se romper do que a camada intermediária na temperatura em que o destacamento é efetuado, de tal modo que a camada de vedação térmica se rompe, preferivelmente a se destacar continuamente através da camada intermediária, uma vez que o destacamento tenha sido efetuado através da zona termicamente vedada, e embalagens produzidas a partir destes.
