The laminating machine manufacturer briefly analyzes the pre-coated film. This process does not require a binder heating and drying system, which greatly simplifies the laminating process, and the operation is very convenient. It can be turned on at any time, and the production flexibility is large, and there is no solvent odor. No environmental pollution, more importantly, it can completely avoid bubbles, delamination and other failures. Its finished products have extremely high transparency and have broad application prospects and promotion value.
        Brief analysis of the laminating machine manufacturers. The structure of the pre-coated film is composed of a substrate and an adhesive layer. The substrate is usually PET and BOPP film. From the perspective of material cost and processing technology, most pre-coated film substrates use BOPP film with a thickness of 12 -20 microns, the thickness of the glue layer is 5-15 microns. According to different processing equipment and process conditions, different thicknesses of adhesive layer are selected. The adhesive layer is divided into hot melt adhesive and organic polymer low temperature resin. The difference between the two is that hot-melt adhesives are made by blending and modifying several materials of the main tackifier resin, tackifier and modifier, while the organic polymer resin is a single polymer low-temperature copolymer.
        Laminating machine manufacturers stated that due to limitations in technology, production equipment, and raw materials, pre-coating films (mostly hot-melt adhesives) produced by domestic equipment still have quality defects. Because there are production processes that rely on a process similar to that of coating the film, the colloid is dissolved with an organic solvent, and the roller is coated on the substrate film with a concave anilox roller, so there is insufficient solvent evaporation, and an odor occurs during operation. After coating, the solvent evaporates and the surface is prone to blistering. At the same time, because the hot-melt adhesive is blended with several kinds of polymer materials, during use, poor temperature control will cause degradation and cross-linking of the polymer in the hot-melt adhesive, resulting in poor coating surface. Some pre-coated film colloids are easy to adhere to the outer surface of the substrate, resulting in poor winding. Since the adhesive layer is thin and the surface is not activated, defects such as insufficient adhesion to the printed matter are likely to occur. Since the hot-melt adhesive is composed of several materials, the transparency after coating is significantly worse than the low-temperature pure resin pre-coating film.

        Brief analysis of the laminating machine manufacturers The pre-coating laminating machine is a laminating equipment with the least investment and the best effect. It is because the pre-coating laminating machine uses an environmentally friendly laminating process, and the operation is simple and the investment is small. It is easy to use. Whether it is mass production or a small amount of laminating, it can be used conveniently. The laminating machine widely used on the market today is a small laminating machine. Therefore, the market potential of the small laminating machine is huge, and the products that use the laminating machine for post-printing processing must have strong market competitiveness. We developed and sold a series of small laminating machines to bring the most affordable, direct and convenient service to our customers.
