A process for the preparation of monolayer structure of a biaxially oriented Polyamide Film

摘要

Process for the preparation of monolayer structure of a biaxially oriented Polyamide Film, which is used conventionally in the preparation of monolayer Films of nylon film.Includes the following steps: First, MINGLE intimately from 1 to 50 parts by weight of a Random Copolymer of ethylene - ethylenically unsaturated carboxylic acid, 50 to 99 parts by weight of a Polyamide Resin; Second, takes the mixture formed in an extruder, where they are mixed. Uadamente components of the mixture; and finally,The mixture is Extruded through a nozzle to form the mixture into a blown film monolayer. Mixing in the Extruder is maintained at a temperature above the temperature of the mixture in the nozzle.
