Water-based coating adhesive is a product based on water-based environmental protection emulsion system, which is mainly used in the field of packaging and printing, and can firmly bond film materials to paper and other surfaces. Characteristics of water-based coating adhesive Fast dry ：Under the appropriate temperature and pressure conditions, the water-based coating adhesive will dry quickly and improve production efficiency. Strong adhesion: It can effectively keep the material firmly bonded, withstand external forces such as stretching, twisting or shearing, and avoid problems such as detachment, spots or cracking. Good weather resistance:The film formed by water-based film adhesive after drying has good weather resistance, can resist the erosion of environmental factors such as sunlight and moisture, and increase the service life of the coated material. Application scenario of water-based coating adhesive Water-based film adhesive is usually used to compound paper with BOPET/BOPP film, and is widely used in print surface treatment. After composite, the gloss and color saturation of the printed product will be improved, while preventing scratches and stains on the surface of the printed matter, improving the durability and quality of the printed matter. The composite of paper and BOPET/BOPP film usually adopts the dry composite process of drying channel: the water-based coating adhesive is evenly coated on the surface of the film, and the water in the water-based coating adhesive begins to evaporate through heating and ventilation of the drying channel. At this time, the film and paper coated with glue are combined to form a stable composite structure. Sinograce waterborne film adhesive is widely used in the drying process of paper and BOPET/BOPP film. The product can dry quickly, has good leveling, initial viscosity and freeze-thaw stability, and has excellent bond strength to achieve a firm and flat film effect. Sinograce water-based film adhesive has a wide range of application, has good adaptability to gold and silver printing products, and has obvious reinforcement effect on the paper coating with a loose surface. Its process is simple, easy to operate, environmental protection, and is especially suitable for the use of medium and high speed automation equipment. In addition, the product also has excellent resistance to embossing and bump properties, which can meet a variety of complex post-processing requirements.

An important link in the production of color printing packaging is after color printing or paper-plastic film decoration, now the means of packaging products mainly rely on film or glazing, advertising instructions, books and notebook covers, commodity packaging and signs are all so. In terms of surface coating or glazing, there are now a variety of decorative methods to choose from, such as: (1)Cover BOPP, PE or PVC plastic film with water-based laminating glue; (2)With organic solvent-based coated plastic film; (3)Cover the plastic film with a plastic film pre-coated with adhesive; (4)Select the high-grade coated paper that has been coated with finishing agent directly, and no longer polish or laminate after printing; (5)After printing, the surface is coated with water-based polishing oil; (6)The surface is coated with organic solvent-based polishing oil; (7)With UV UV curing glazing oil and so on. Correct understanding of the advantages and disadvantages of these surface decoration methods, how their respective vitality, how the future development trend, not only for the packaging and printing industry is extremely important, the development and production of related adhesives, glazing oil, finishing agent, plastic film, laminating and glazing machinery and equipment manufacturers are also extremely important. First of all, let's talk about the performance and use characteristics of water-based film adhesive, it is a white emulsion adhesive composed of water as a dispersing agent and high molecular polymer as a dispersing phase. The real water-based film adhesive should not contain any organic solvent, the residual organic monomer should be less than 0.1%, and it smells no odor or slightly alcohol or ester fragrance. Good water-based coating adhesive can be used for water-based machine, can also be used for oil machine, water machine structure is simple, cheap (2.5 ~ 100,000 yuan/set), driving speed, is generally 2 times the speed of oil machine. Good water-based adhesive content is about 1 times higher than oil-based adhesive, and it is wet coated, and the adhesive is dry and transparent by the absorption and distribution of water by the paper fiber after coating, and firmly bonded with the plastic film. The product gloss and whiteness of water-based adhesive are better than that of organic solvent-based adhesive, and the adhesive force is equivalent to solvent-based adhesive. And water-based adhesive with water-based machine coating using cold bonding method, without heating drying, can save a lot of energy; Due to the high content of water-based adhesive, the coating area of water-based adhesive of the same weight is more than 50% larger than that of solvent adhesive, so the product cost of water-based adhesive coating is much lower than that of solvent adhesive; Because water-based adhesive does not contain toxic, flammable, explosive, environmental pollution of organic solvents, but also reduce the risk of fire, because water-based adhesi...

That is, metal foil printing adhesive, commonly known as hot stamping adhesive, is a special performance adhesive, but also the key to the success of metal foil printing. product presentation Hot stamping adhesive consists of a special adhesive composed of a suitable hot melt adhesive and a bonding resin, which is composed of two points: 1.There are polyamide series, polyester series, polyethylene series, polyurethane series of hot melt adhesive. 2.Bonding resins (adhesives) have PA series (containing acrylonitrile) and PU series The above two parts are reasonably combined to form a special adhesive with metal foil printing requirements of printing paste through the net and good movement performance, can get a uniform coating on the cloth can be appropriate to the base cloth without excessive penetration should also be low hot melting point, no shrinkage, washable, dry cleaning resistance is good, feel soft. Application range The application range is according to the product requirements pressing flat, round surface, copying surface. operational process The gold stamping silicone roller transfers the pattern of the object to the flat surface through the pressure of the rubber roller. The silicone roller can print a large area of the pattern can also print a flat pattern. Characteristics and requirements High temperature resistance, heat conduction, the higher the hardness of silica gel, the higher the hardness of hot stamping plate, the higher the high temperature resistance. Soft silica gel high temperature resistance, thermal conductivity will be poor.
