METHOD FOR LAMINATING THERMO-ADHENSIVE FILM

摘要

PURPOSE: A heat sealing film lamination method is provided to promote the adhesive property of a heat sealing film using a hydrophilic bonding method. CONSTITUTION: After hydrophilic polymer solution is coated on a first substrate, a polymer film is formed by eliminating a solvent by heating the first substrate(S100). A thermoplastic film is laminated using heat remained in the polymer film(S200). After the hydrophilic polymer solution is coated on the second substrate, the polymer film is formed by eliminating a solvent by heating a second substrate(S300). The first substrate is laminated on the second substrate(S400).
