Abstract

a presente invenção fornece filmes multicamada e embalagens formadas a partir de tais filmes. em um aspecto, um filme multicamada compreende uma camada a, que é uma camada vedante que tem uma superfície facial superior e uma superfície facial inferior, sendo que a camada a compreende (a) um copolímero que compreende etileno e acrilato de alquila, em que o copolímero tem um índice de fusão (i2) de 2 a 30 g/10 minutos, e sendo que a quantidade total de acrilato de alquila no copolímero é de 5 a 30 por cento em peso com base no peso do copolímero, e (b) um elastômero de poliolefina que tem uma cristalinidade de 30% ou menos e índice de fusão (i2) de 1,0 g/10 minutos ou mais; e uma camada b que tem uma superfície facial superior e uma superfície facial inferior, sendo que a superfície facial superior da camada b está em contato aderente com uma superfície facial inferior da camada a.
