The common post-processing technology of self-adhesive copper plate label paper mainly includes the following:
1.Laminating: This is a traditional post-processing technology, mainly through the base paper composite film composite on the self-adhesive label machine, so that the base paper composite film is coated under the action of the composite device. The film can increase the gloss of the label surface, and achieve the effect of anti-fouling, anti-moisture, and protection of the pattern. The coating process is mainly divided into bright film and dumb film, and the appropriate film is selected for covering according to the specific needs of the label.
2.Glazing: The glazing process is mainly to increase the gloss of the surface of the self-adhesive label, and it can also achieve the role of anti-fouling, anti-moisture and protection of the pattern. The glazing of self-adhesive label materials is divided into sheet paper glazing and web glazing, of which web is the method that most of the self-adhesive label printing processes will use. After glazing, a protective film is formed on the surface of the label to improve the durability and beauty of the label.
3.Gold/silver stamping: This is a method of using a printing adhesive to allow the metal foil to be transferred to achieve the effect of gold or silver stamping. This process can increase the visual effect of the label, making the label look more high-end and exquisite. Gold/silver stamping process is mainly used in key parts such as LOGO and product name to enhance the added value of products.
4.Die-cutting: Die-cutting is to use a die-cutting machine to cut the printed label according to the design draft, so that it becomes a single label shape. In the die cutting process, the selection and adjustment of the die cutting tool is very important, and it is necessary to make accurate adjustments according to the shape and size of the label to ensure the quality of the die cutting. The edge of the die-cut label is neat and free of burrs, which is convenient for subsequent use.
5.Slitting and discarding: Slitting is to cut the die-cut labels into small rolls or sheets according to the specified number. Pay attention to the slitting precision and the stacking mode of labels. Waste removal is to remove the waste generated during the die cutting process, leaving only the required label. These two steps are to improve the yield and efficiency of the label.
6.Other special processes: In addition to the above common post-processing processes, self-adhesive copper plate label paper can also use other special processes according to specific needs, such as embossing (printing a layer of bright and slightly embossed polish in the required area of the label), and embossing (pressing a bumpy pattern on the label). These special processes can further enhance the visual effect and texture of the label to meet different market needs.
It is important to note that different post-processing processes may vary depending on the specific production environment and customer needs. In practical applications, the appropriate post-processing process needs to be selected according to the specific requirements of the label and production conditions.
