Abstract

La presente invención se refiere a un laminado que se puede desgarrar transversalmente, caracterizado porque consiste de una película de polietileno lineal de baja densidad orientada en la dirección de la máquina laminada adhesivamente en por lo menos un lado a una película sellante, la película sellante tiene un desgarramiento Elmendorf en la dirección de la máquina de por lo menos aproximadamente 2 g/micra, y la selección de la película orientada y la película sellante se hace sobre la base de que; K.X(1-Y), en donde K es un factor que se determina empíricamente el cual depende de las propiedades de la película orientada y la película sellante, X es el espesor de todas las capas de película sellante en micras, Y (MDc)/(TDc) MDc es la resistencia el desgarramiento Elmendorf, en la dirección de la máquina de la película orientada, medida en gramos y TDc es la resistencia al desgarramiento Elmendorf, en la dirección transversal, de la película orientada, medida en gramos.
