Abstract

La presente descripción proporciona una película multicapa. La película multicapa incluye una primera capa exterior y una segunda capa exterior, en donde al menos una de la primera y la segunda capa exterior comprende un primer polietileno; una capa central entre la primera y la segunda capa exterior, en donde el espesor de la capa central es de 8 a 30 % del espesor total de la película multicapa. La capa central está formada por un polímero central que comprende de 20 a 0 % en peso de un segundo polietileno y de 80 a 100 % en peso de un elastómero a base de propileno que tiene una densidad de 0.855 g/cm3 a 0.877 g/cm3, el % en peso es en función de un peso total de la capa central. La película multicapa comprende de 8 a 30 % en peso del elastómero a base de propileno, en función de un % en peso total de la película multicapa. La película multicapa también incluye una primera y una segunda capa interior, en donde al menos una de la primera y la segunda capa interior comprende de 80 a 100 % en peso de un LLDPE que tiene una densidad de 0.870 g/cm3 a 0.912 g/cm3 y de 20 a 0 % en peso de un LDPE, en donde la capa central está situada entre la primera y la segunda capa interior.
