Abstract

Un artículo de empaque tiene iniciadores de desgarre para iniciar un desgarre manual que puede propagarse para abrir un empaque y permitir que un producto sea quitado prontamente del mismo, sin el uso de un cuchillo o tijeras o cualquier otro implemento. El artículo de empaque está hecho de una película de múltiples capas que se puede encoger con calor teniendo por lo menos una capa que contiene una mezcla de polímero incompatible y/o una capa que contiene un relleno inorgánico, y/o una capa teniendo un módulo de Young alto. La película también tiene una resistencia al impacto dé carga pico de por lo menos 50 Néwtones por milímetro. Los iniciadores de desgarre se pueden usar para generar un desgarre manual en dirección de la máquina para abrir el empaque, con el desgarre manual en dirección de la máquina siendo capaz de propagarse en la dirección de la máquina al borde opuesto del artículo de empaque. También se describe un proceso para hacer un empaque y abrir manualmente el empaque.
