MANUFACTURE OF LAMINATED DRAWN FILM

摘要

PURPOSE:To manufacture the laminated drawn film having excellent properties through a simple process by bonding a polyolefin layer to a polyester film through a denatured EVA copolymer and drawing the laminated film. CONSTITUTION:The polyolefin layer is bonded on at least one surface of the polyester film through the denatured ethylene-vinyl acetate copolymer, and the laminated film is drawn at a 4-20 times area drawing rate in the longitudinal direction and/ or the transverse direction at 80-150 deg.C. Accordingly, the laminated drawn film which can jointly display the excellent optical properties and mechanical properties of the polyester film and a heat seal property of a polyolefin film can be manufactured through the simple process.
