The temperature control of the laminating process of the pre-coating and pre-coating machine also affects and determines the hot-melt adhesive used for laminating to solve the changes when heated, and the resistance to the new heat. Therefore, strict temperature control is the primary key to the pre-coating film machine. According to the practical process, it is found that the quality of the pre-coating laminator is mainly affected by three factors: temperature, pressure, and speed. Therefore, the relationship between the three is correctly handled to ensure the quality of the pre-coating laminator and to the production process of the next process. The impact is very important. The paper-plastic coating will be the comprehensive result of the physical function of thermocompression. Temperature, pressure, and speed are the three basic factors for achieving this physical comprehensive effect. Correctly handling the relationship between the three is the process operation. The key to technology.

        Temperature is the first key to laminating. The adhesive used for pre-coating is hot-melt adhesive. Temperature determines the melting state of hot-melt adhesive, the leveling performance of hot-melt adhesive, and the molecules of hot-melt adhesive to the film. , The printing ink layer, the paper substrate and other three molecules of the diffusion capacity of molecules, but also determines the crystallinity of the hot melt adhesive, only the correct control of the temperature of the working area can make the pre-coated film on the film of solid hot melt adhesive The layer is completely melted into a viscous state, with suitable fluidity to achieve wetting and bonding to the surface of the printed matter, and at the same time to ensure immediate solidification after compounding, so that the laminated film product has a smooth appearance, bright enough, and the adhesive layer is melted well without folding mark. And can peel the ink.
