Abstract

Composições poliolefinicas e filmes permeáveis obtidos a partir delas. O presente invento descreve filmes especialmente adequados para a embalagem de alimentos frescos, como saladas e verduras, devido à sua alta permeabilidade a oxigênio, dióxido de carbono e vapor d'água, os quais são obtidos a partir de uma composição poliolefinica compreendendo (percentagens em peso): A) de 5 a 80% de um polímero de buteno-1 ou composição polimérica contendo de 0 a 25% de um ou mais comonómeros escolhidos dentre etileno e a-olefinas diferentes de buteno-1, desde que, quando o etileno estiver presente somente como comonómero, a quantidade de etileno é maior que 4% e está presente uma fração copolimérica (i) contendo pelo menos 6,2% de etileno, dito polímero ou composição polimérica tendo um teor de fração solúvel em xileno a 0 °C de 50 a 100% e um módulo flexional (medido de acordo com a norma ISO 178) de 15 a 300 MPa; B) de 20 a 95% de um homopolímero ou copolímero de propileno tendo um teor de fração insolúvel em xileno à temperatura ambiente de 93% ou mais.
