Abstract

APERFEIÇOAMENTO INTRODUZIDO EM LAMINADOS TERMOPLÁSTICOS MULTICAMADAS PARA EMBALAGENS E OS ARTIGOS FABRICADOS A PARTIR DESTES. Laminados de filmes para aplicações em embalagens possuindo ao menos duas camadas de polímeros as quais são formadas em conjunto como um filme coextrudado por sopro tal que a primeira camada de polímero seja uma camada de superfície relativa ao filme e compreenda um material selável por calor possuindo um índice de fusão de ao menos 2Og/ 10min. A presente invenção também fornece embalagens para alimentos formadas a partir destes filmes laminados.
