With the rapid development of printing and packaging industry, the appearance design of products is becoming more and more high-end. The composite technology used in modern exquisite printing mainly includes: paper printing and plastic film composite and plastic printing and plastic film composite, that is, paper-plastic composite and plastic-plastic composite.As a new type of packaging material, ...
There are many factors affecting the quality of the film, in addition to paper, ink layer, film, adhesive and so on In addition to the objective factors, it is also affected by subjective factors such as temperature, pressure, speed, and glue amount. If these factors are not handled well, various laminating quality problems will occur. There are snowflakes on the product 1.The amount of glue is to...
In the actual operation of our manufacturer, whether the laminating products can normally complete the factory and meet the requirements of customers, in addition to the quality of the laminating glue itself, it is also related to the supporting factors such as paper, film, equipment accuracy, environment, and operating experience in the composite process. Often in some small details, it will caus...
Whether the water-based film adhesive meets the quality requirements of composite products, in addition to the quality of the glue itself, but also related to the paper, film, equipment accuracy, operating experience and other supporting factors in the film coating process, after long-term practice, we summarized the common problems in the application of water-based film adhesive, and put forward ...
Common problem Cause Solution The middle part of the compound bubbles Add dry oil when brushing Dry and then recombine The amount of glue is too small Increase glue Film or print surface contamination or excessive dusting Dedusting The overflow on the surface of the rubber roller is not removed, causing the mucous membrane to empty Cleaning glue roller The pressure is too small, and the ...
As a kind of widely used adhesive, coated adhesive has a variety of processes. Here are some of the common processes used: 1. Hot melt coating: hot melt coating is to place a layer of film on the surface of the print, and then through hot pressing the film and the print together.In this process, the laminating glue is heated to turn it into a liquid, which then forms a uniform coating between the ...
Brand :Sinograce Type: Water base adhesive Appearance:Milky white emulsion with blue light Performance and use:This product is suitable for the coating of BOPP film, PET film and printed color paper (dry coating process). High bonding q degree, large tension compound drying speed, good parallel flow; For gold and silver cardboard, single powder paper bonding q degree, tension q, to avoid the...
First, the choice of self-adhesive printing raw materials When selecting raw materials, we must choose high-quality self-adhesive materials with qualified physical and chemical indexes, rather than products with expired or unstable physical and chemical indexes. Although the latter price is low, but due to the unstable quality of such materials, large consumption in each process, and even lead to ...
Ink resin is the pigment carrier in the ink, is the core material of the ink, its quality is good or bad, will directly affect the performance of the ink, because the connection material to a large extent determines the viscosity of the ink, viscosity, dryness, fluidity and other properties. Color fastness The adhesion between the ink and the substrate mainly includes the chemical bond force ...
Organic pigment is the most basic material to provide color to the ink, but as the ink attached to the surface of the substrate, the color shown to the consumer often produces more or less deviations from the color of the pigment itself. The reason is that in the ink, the pigment particles do not exist alone, but are dispersed in the connecting material medium. Microcosmic, the best wetting disper...
Anti-viscosity is an important physical property index of printing ink.Gravure printing is a kind of printing method with high ink supply, good reproducibility and fast printing speed. Most of the inks used are solvent-based volatile drying inks.After the ink is transferred to the substrate through the printing plate, it passes through the drying channel, and the organic solvent is quickly volatil...
In gravure printing, ink resolubility is also a key indicator to test the performance of ink. Especially in the color ink printing, the moderate resolubility can not only make the color fully displayed, but also solve the problem of shallow plate mesh blocking and overprinting cross-color. In color ink printing, according to the different hue requirements, the depth of the ink hole mesh of the pri...
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...
In order to prevent ink delamination and pigment precipitation, users must be fully stirred before printing. The following summarizes the faults and elimination methods of screen printing ink in use for your reference. 1.Poor adhesion: the reason is improper selection of ink, insufficient pre-press treatment, impurities in the substrate, insufficient drying temperature, insufficient time, improper...
The resins that can be used for water-based gravure inks are acrylic resin, polyurethane resin, alkyd resin, etc. Each resin has different characteristics and application occasions, and needs to be selected according to the actual situation. First, water-based gravure ink overview Water-based gravure ink is an environmentally friendly ink, compared with traditional ink, its volatility is small, no...
With the development of the application of digital inkjet printing technology in the clothing industry, environmental monitoring is more stringent and the demand for small batch production and personalized customization is increasing. Therefore, the requirements for textile coating ink are becoming higher and higher, and the raw materials for the production of textile coating ink are bec...
