Abstract
Estructuras de película termoplástica que contienen una cantidad predominante de materiales resinosos de coste relativamente bajo utilizados comúnmente en la fabricación de bolsas de la técnica anterior tales como, por ejemplo, resina de polietileno de densidad baja para usos generales pueden transformarse en artículos tales como bolsas que tienen rigidez, es decir, módulo, y características de resistencia mejoradas sobre las bolsas de polietileno de la técnica anterior. En general, se ha encontrado que una estructura laminar que comprende al menos una capa de resina de polietileno de densidad baja para usos generales que tiene un espesor del orden de aproximadamente 50% a 90% y preferiblemente de aproximadamente 65% hasta aproximadamente 85% del espesor del estratificada total puede unirse a una segunda capa.
