9Why should the surface of the tag be coated or oiled?

In the printing industry, hang tags, color cards, and packaging color boxes are common prints. I wonder if you have found that there is a layer of transparent film on the surface of these hang tags, such as clothing hang tags, jewelry hang tags, and so on. This film is called a "coating" of post press processing technology.

Laminating, also known as "superplastic", "pasting", "pasting", etc., refers to the use of transparent plastic film to protect and increase the gloss of printed materials by hot pressing. The covering film can be divided into "light film", "dumb film" and "tactile film".

Nowadays, many hangtags and packaging color boxes have a film on the surface. On the one hand, it can improve the quality of the product, and the overall color expression is good. On the other hand, it can effectively prevent water and moisture. Then why should the hangtag be surface treated?

In the printing industry, everyone knows that if the surface of the tag is not treated, the color card printing content is easy to scratch, fade or dirty, and the service life is greatly shortened. If the hangtag printed materials after surface treatment, such as "film covering", are glued together after the plastic film is heated and the hangtag printed materials are pressurized to form a paper plastic integrated elevator. Thus, a layer of transparent film is added to the surface of the elevator print, which not only becomes more smooth and bright; It also has the functions of moistureproof, waterproof, antifouling and wear-resisting, and it also extends the service life of hangtag printing.

In addition to film coating, the surface of the tag can also be treated with "grease", which can also prevent scratches, discoloration, dirt and prolong the service life of the tag printing.
