Self-adhesive labels, such as self-adhesive labels, timely stickers, pressure-sensitive paper, etc. , is a composite material with paper, film or special materials as the fabric, adhesive coated on the back, and silicon-coated protective paper as the backing paper, which is printed and die-cut to become the finished product label. In application, the backing paper can be attached to the surfaces of various materials with a single press, or it can be automatically labeled on the production line with a labeling machine. We can see all kinds of self-adhesive labels in the market, but we really don't know much about its classification. In fact, there are two kinds of self-adhesive labels on the market: one is paper and the other is film. ? Film category: there are also some packaging products that need high temperature and water resistance. Some car stickers, reflective films, etc. They have to be used outdoors, so they need to be made of film self-adhesive materials after a long period of wind and rain. Although film labels have a wide range of applications, paper labels also have characteristics that film labels do not have. For example, in terms of writing on labels, film labels can no longer be written on stickers, while paper labels can, so it is easy to distinguish. Different materials have different functions. Although the products used are different, the effect is roughly the same. No matter how classified, paper self-adhesive labels and film self-adhesive labels belong to one kind of self-adhesive. When we use them, we can apply them to different products according to different functions, so that they can achieve the best use effect. What are the advantages of film sticker over paper sticker? Structure and characteristics of thin film materials.

The structure of (1) structural membrane material is the same as that of paper material, the only difference is that the surface of the material needs to be treated.

(2) Surface characteristics and treatment methods? The principle of ink layer forming pattern on printed matter is infiltration, volatilization, conjunctiva and curing. Because of the high film density, the ink can only volatilize, conjunctiva. There is no infiltration during the curing process, so the surface of the film needs special treatment. The function of surface treatment is to improve the surface tension of film, which is greater than the surface tension of ink, so as to achieve the correct combination of ink and film materials.
