Abstract

An apparatus for manufacturing a vacuum packaging film and a film manufactured by the same are provided to solve problems of inconvenience due to separate operation and complexity of processes. An apparatus for manufacturing a vacuum packaging film includes a T-die(12), a cooling roller(13), and an embossing cooling roller(14). The apparatus extrudes a resin layer formed of a gas blocking resin, a thermal adhesive resin, and an adhesive resin for adhering them. The resin layer passes through the T-die(12), and then, cooled by the cooling roller. Next, the resin layer passes through the embossing cooling roller to be formed as a patterned layer having an embossed or depressed pattern.
