Abstract

a presente invenção refere-se a um método para produção de uma trama de película durante o qual uma trama de película inicial feita de material de polímero termoplástico com uma matriz de polietileno, onde 1 a 70 partes em peso de polipropileno, com relação a 100 partes em peso de matriz de polietileno, estão contidas, é, após ser aquecida, guiada através de um intervalo de rolo frio (7,8), com o que a trama de película inicial é aquecida apenas até que o material de matriz de polímero derreta mas não para uma temperatura na qual o polipropileno derreta.
