METHOD FOR MANUFACTURING ORIENTED POLYOLEFIN FILM AND ORIENTED POLYOLEFIN FILM MANUFACTURED THEREFROM

摘要

Disclosed are a method for manufacturing an oriented polyolefin film for thermal lamination and the oriented polyolefin film for thermal lamination manufactured therefrom. Since the method comprises additional extrusion and cooling steps after orientation in the longitudinal direction, a resin layer is laminated through the additional extrusion step and lamination through successive extrusion thereof is enabled if a resin has a low melting point. Therefore, the manufacturing process is simple and the manufacturing time is reduced, thereby reducing production costs for products and improving an interlayer adhesive force.
