Self-adhesive labels have always been a common printing product. Today, printing technology is even more mature and the printing quality is getting better and better. 1. The surface material is the surface material, which is the material that accepts printed images on the front and accepts adhesives on the back and is finally applied to the adhered object. Generally speaking, all materials that can be flexibly deformed can be used as the fabric of self-adhesive materials, such as commonly used paper, film, composite foil, various textiles, thin metal sheets and rubber. The type of surface material depends on the final application and printing process. The surface material should be able to adapt to printing and have good ink absorption2. Surface coatingIt is used to change the surface properties of the surface material. Such as improving surface tension, changing color, adding a protective layer, etc., so that it can better accept ink and be easy to print, so as to prevent dirt, increase ink adhesion and prevent the printed images from falling off.3. AdhesiveThe adhesive is the medium between the label material and the bonding substrate, which plays a connecting role. According to its characteristics, it can be divided into two types: durability and removability. It has a variety of formulas, suitable for different surface materials and different occasions. Adhesive is the most important component in the technology of self-adhesive materials and the key to label application technology.
4. Back coating or back printingBack coating is a protective coating on the back of the base paper to prevent waste discharge. The adhesive around the rewound label is bonded to the base paper. Another function is to make multi-layer labels. The back printing function is to print the manufacturer's registered trademark or pattern on the back of the base paper to play a role in publicity and anti-counterfeiting.5. The bottom coating is the same as the surface coating, but it is applied on the back of the surface material. The main purpose of the bottom coating is: self-adhesive label①Protect the surface material and prevent the penetration of adhesive.②Increase the opacity of the fabric;③Increase the bonding force between the adhesive and the surface material;
