Abstract
Un saco para envió que tiene paredes formadas de una película mezclada de polietileno orientada en un sólo eje, en donde la película se produce soplando y estirando en frío la mezcla de polietileno con una proporción de tracción a la proporción de soplado menor que 2:1 preferentemente, entre 1:1 y 2:1. El saco puede usarse como un saco de envío tubular para un material ligero de peso y voluminoso o como saco para un carga pesada. Los sacos presentan propiedades físicas mejoradas.A mailing bag having walls formed of a single axis oriented polyethylene mixed film, where the film is produced by cold blowing and stretching the polyethylene mixture with a tensile to blowing ratio less than 2: 1 preferably between 1: 1 and 2: 1. The bag can be used as a tubular shipping bag for a light weight and bulky material or as a bag for a heavy load. The bags have improved physical properties.
