MANUFACTURING METHODS OF VINYL RESIN FOR VACUUM PACK AND THE VINYL RESIN FOR VACUUM PACK THEREOF

摘要

PURPOSE: A method for manufacturing a vinyl fabric for a vacuum wrapping pack is provided to lower oxygen penetration rate and to enable fresh storage. CONSTITUTION: A method for manufacturing a vinyl fabric for a vacuum wrapping pack comprises: a step of adhering O-nylon film layer and LEPD(low density polyethylene) film layer with an adhesive; a step of inserting inner PE film layer(30) between the LDPE film layer and LLDPE(linear low density polyethylene) film layer; a step of laminating and performing thermalcompression to form embossing on the surface of the outer PE film layer to obtain air way.
