Color printing packaging is light in weight, easy to carry, and the source of raw materials is wide, and it is widely used in food, traditional Chinese medicine, daily necessities and other industries. Do you know what are the common production processes of packaging? First, the film Laminating process is a kind of surface processing process, after printing is completed, this process is also called "plastic", "laminating", "laminating", through hot pressing on the surface of paper products with a layer of transparent plastic film, so that the surface of the printed matter more shiny, on the other hand, the printed matter also played a protective role, this is laminating, at present, The film coating process is often used for book covers, picture albums, postcards and maps. Two, hot stamping Hot stamping is to first make the pattern or text that needs to be hot stamped into a convex plate, and with the help of hot pressing method, a variety of aluminum foil sheets are printed on the substrate, showing a strong metallic light, so that the product has a good texture. It is often used for decoration of household appliances and electronic products. Three, die cutting indentation Die-cutting indentation is a process of post-printing processing, which will no longer limit the edge shape to right angles according to its own desired graphic specifications. The indentation process is to use a wire cutter or a wire die to press out line marks on the sheet material through the action of pressure, or use a rolling wheel to roll out line marks on the sheet material, so that the sheet material can be bent and formed according to a predetermined position. With the improvement of people's exquisite degree of product printing and environmental protection requirements, there are more and more production methods of printing and packaging, as long as one of the above processes is mastered, it will be able to better speed up the production process.

Water-based adhesives for printing are very common, which mainly include water-based pasting adhesive, laminating adhesive, water-based sealing adhesive and so on. Water-based laminating adhesive Water-based film adhesive has been widely used in recent years for its high brightness, low cost, easy operation and water-based environmental protection. Water-based film adhesive is mainly divided into cold paste composite and dry composite two kinds. The current market is mainly based on cold paste composite, but the development speed of dry composite is getting faster and faster. Water-based cold-paste coating machine covers less land, consumes less power and is easy to operate. The water-based dry film coating powder has strong ability, high stiffness of the finished product, strong adhesion, and good adaptability to ink. Water-based sealant Adhesive With the improvement of people's demand for packaging aesthetics, binding can no longer be met. Therefore, using adhesive to seal printed matter has become a good choice. The water-based sealant has become the mainstream of the market because of its water-based environmental protection, flexible film and good aging resistance. Water-based sealers are generally milky white to slightly yellow viscous liquid. The water-based sealers of different manufacturers have great differences in opening time, initial viscosity, durability, odor and appearance. It is suggested that when people in the industry choose, they should make full tests on the low temperature resistance, durability and peel strength of the bonded products before choosing, and try to choose manufacturers with large output and high quality control level. Sinograce Chemical produces all kinds of water-based glue, acrylic glue.It has strong adaptability to various printing surfaces, good initial adhesion, high bonding strength, good leveling properties, excellent film-forming speed, fast drying of composite products, good stiffness, and good pasting resistance. It is used for dry lamination of paper and PET/BOPP films. It has good adaptability to hot hot stamping products . It can adapt to a wide temperature range and has excellent cost performance. The process is simple, easy to operate and environmentally friendly.

Coated adhesive is generally used in the field of printing, processing the surface of the printed matter, so as to improve the gloss of the printed matter, and play a certain protective effect on the printed matter, coated adhesive refers to the BOPP film on the paper of a kind of glue. Divided into oil-based laminating glue and water-based laminating glue, water-based laminating glue is widely used in China's printing enterprises. Properties of film adhesive The coating adhesive has the advantages of fast drying speed, high brightness, high peeling strength, strong adhesion, resistance to rolling line, smashing and embossing, and good adaptability to hot stamping, gold printing and silver printing. Widely used in book covers, packaging boxes, handbags, exquisite albums and other processing. Characteristic ● Cost-effective, simple process. ● Easy to use, fast film formation speed. ● Strong adhesion, wrinkle-free film. ● Good comprehensive performance, composite drying fast. The use of film adhesive process and precautions: 1.The way of laminating is dry laminating, which means that the laminating machine should use a dry laminating machine that can be heated by a drying channel and a composite roll. 2.The compound pressure is about 8-20 kg. The drying temperature is about 60-90 ℃. The temperature of the composite pressure roller is about 50-90 ℃. 3.If conditions permit, the glue is baked to seven to 90% dry is appropriate, in this condition, the product after the film is high brightness, stiffness and fastness. In order to prevent bubbles from appearing in the film, the temperature of the composite pressure roller needs to be reduced to below 50 ° C to prevent the glue from being squeezed out. The pressure should be reduced slightly.  4.In order to prevent the discoloration of gold card paper and ink, the glue should be completely dried. 5.When the glue is completely dried, the temperature of the composite pressure roller is as high as possible without burning the film, and the greater the pressure, the better.
