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)C...
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...
Laminating glue is currently a kind of strong glue widely used in the market, so what is the application processing process of laminating glue? The application processing technology of laminating glue is as follows: 1, the composite method is dry composite, that is, the coating machine should use a dry composite machine with curing furnace and composite roller heating. 2, curing furnace ambient te...
After the ink is stored for a period of time, the upper part of the ink appears thin in the container, the viscosity is small, and the color and concentration are relatively poor; The lower part is thick, the viscosity is large, and the color and concentration are also relatively good. Intaglio printing inks are thin and have a small viscosity, because the pigment is poorly dispersed in the connec...
What is a peelable resin? Strippable resin is a special resin material with strippable properties (also known as removable film resin). It is often used in the preparation of protective films for electronic products, packaging of semiconductor devices, etc., which can protect these products more intact, and it is easy to peel off when it needs to be replaced or disassembled. When prepari...
Protective film resin Automobile coating resin High resilience waterborne polyurethane resin 1.Typical properties Appearance： Milky white liquid Protective film resin Automobile coating resin Ph： 7.0-9.0 Automobile coating resin Solid content： 40±1% Charge： Anionic High resilience waterborne polyurethane resin Viscosity (25℃)： 300-800cP Elongation (%)： >200...
1.There are many formulations of coated glue, and different formulations need to be determined according to the specific use. It generally includes basic glue, thickener, curing agent, auxiliaries and other ingredients. 2.Basic glue is the most important component of laminating glue, it can be selected according to different use requirements of different types, such as water-based, oily, dilu...
The performance requirements of water-based varnish for printing paper glazing are as follows: 1.The film has good environmental resistance. Some of the printed matter after glazing is used to make all kinds of packaging cartons, in order to be able to play a good protective effect on the packaged products, the environmental resistance of the glazing film layer must be better. For example, the pac...
Ink scraping is not clean troubled many manufacturers, there are ten reasons for scraping is not clean, save it for use! 1.Ink viscosity is too high When the viscosity of the ink increases, the surface tension also increases correspondingly, and the force between them also increases, so that the scraper will increase the impact force of the ink on the scraper in the contact process with the ink, d...
Different processing methods will cause different fault manifestations, the following we mainly analyze the causes of paper thermit sealing delamination phenomenon under the gravure and solvent-free composite processing methods. The YBB paper aluminum-plastic composite film standard does not specify the composite strength index of the paper aluminum layer in the paper aluminum-plastic composite fi...

Du...
The OPP,PET film substrate | is an environmentally friendly coating using advanced material technology, which can significantly enhance the adhesion of EVA on difficult PET substrates and improve the product quality of PE card film. Card film, also known as plastic film, is a plastic film product coated with adhesive and OPP and PET as the substrate, which is widely used in the storage and protect...
First: the treatment of the substrate First, the substrate (aluminum, stainless steel or other metal substrate) is baked at high temperature (360℃×30 minutes ~380℃×10 minutes) to carbonize the grease or degreaser cleaning for the first step of degreasing. Step 2: Roughening the surface Available corundum sand 80#~120#, pressure 0.4~0.6mpa, sandblasting, so that the surface roughness of the substra...
In the face of different needs of different industries, rollers also need to do the corresponding coating treatment, so as to improve or compensate the relevant performance of the roller. So what are the surface coating technologies for rollers? 01 Coating treatment The coating treatment of the drum includes zinc plating, chromium plating, nickel plating, etc. The different coating treatment can i...
Teflon is the abbreviation of polytetrafluoroethylene, this material has the characteristics of acid and alkali resistance, resistance to various organic solvents, almost insoluble in all solvents, so it has the title of "non-stick coating". With the development of thermal spraying technology, Teflon coatings can be applied to stainless steel, copper, aluminum, magnesium and various alloy metal ma...
People often ask, how long can you spray Teflon paint on the mold? How many molds can you take off? To answer the question about the life of Teflon paint, it is necessary to first explain what factors affect the life of Teflon paint. There are three main factors that affect the service life of Teflon coatings. First: coating formula 1.The primer resin content is too low In popular terms, the ...
