              Application Method of Water-based Dry Laminating Adhesive

              Application Method of Dry Laminating Adhesive

                         Dry laminating adhesive is a kind of new-type, economical&environment-friendly adhesives, which can be widely applicable to oil-type laminating machines. The operation method is basically similar to that of oil-type adhesive,&the following is only for your reference:

              1、Clean such parts as gluing roller&adhesive plate, etc before starting;

              2、During laminating, clean the foreign matters with towels&blades in case of grains&spots in the gluing roller for even laminating;

              3、It is suggested to use blade made from rubber;

              4、It is suggested to divide the drying groove into two parts, with the temperature of 50-80;

              5、The temperature of the gluing roller shall be 85-95&the pressure shall be above 15mpa. Control the real temperatures according to different products;

              6、In case of deep ink, gold&silver plates&large powder spraying quantity, adopt film through large roller so as to avoid paper blistering. Avoid expansion&contraction of films.

              7、Fix the quantity of adhesive according to printing matters, with the speed according to drying speed of adhesive on BOPP film.

              IV. Blistering of Composite Products

              1. Too much powder spraying quantity&too many additives;

              2. Too large temperature of laminating roller;

              3. Too much|too little adhesive.

              V. Wrinkling of Paper

              1. Damping|deformation of printed mattered;

              2. Unbalanced cold-pressing roller;

              3. Too large gluing quantity;

              4. Deformation of laminating roller;

              5. Too large temperature of roller.

              VI. Wrinkling of BOPP Film

              1. Unbalanced delivering roller;

              2. Too large temperature of drying groove; deformation of film; too small blowing quantity;

              3. Uneven BOPP film.
