film formation. You can improve the thermal adhesion, moisture resistance, gas barrier properties, UV-absorbing and antistatic properties of the film. For example, to improve the stretched polypropylene film (OPP) and the heat-adhesive gas barrier properties, vinylidene chloride resin solution is coated and dried, is the use of this method. Dry compound method: dry composite method is also called dry laminated composite, which process is: solvent-based adhesive coated on the basis of the film (greater intensity composite base material), and after thermal bake the adhesive an adhesive material layer, the solvent is completely evaporated, then the second layer on a substrate by heating pressure composite, the composite not only for composite
