1. Surface material: it is the carrier of adhesive sticker label content. The back of the surface paper is coated with adhesive. The surface paper can be made of many materials, generally including coated paper, transparent PVC, static PVC, PET, holographic paper, heat-resistant paper, PP, PC, kraft paper, fluorescent paper, metallized paper, silver-plated paper, synthetic paper, aluminum-foil paper, fragile (security) paper, textured paper, Tyvek/nylon paper, iridescent paper, sandwiched coated paper, and thermal paper.

2. Film material: transparent PET, semitransparent PET, transparent OPP, semitransparent OPP, transparent PVC, gloss clear PVC, no-gloss clear PVC, synthetic paper, gloss gold (silver) PET, no-gloss gold (silver) PET.

3. Adhesive: general super adhesive, general strong adhesive, cold storage food super adhesive, general removable adhesive, fibre removable adhesive. It ensures the proper adhesion of the backing paper and the surface paper, and strong adhesion with the substance in contact after surface paper is removed.

4. Backing paper material: release paper, commonly known as "backing paper”, is not viscous on the surface with low surface energy. The backing paper has an isolation effect on the adhesive, so it is used as the adhesion of the surface paper, in order to ensure that the surface paper can be easily removed from the backing paper. Common backing papers include white, blue, yellow Glassine paper or onion paper, kraft paper, PET, coated paper, polyethylene (PE).

Self-adhesive printing is the process of transferring ink and other substances by the printing forme to the surface of the substrate precoated with adhesive at the back. Compared with ordinary printing, adhesive has the following characteristics:

It takes a small investment and it pays off quickly. Adhesive sticker printing materials are mostly trademark and sticker, with smaller size, fast printing speed, and less production waste.

It is printed in a flexible manner. Adhesive is not limited by the way of printing. Traditional printing houses can use offset or screen printing press for printing.

It has many functions. Adhesive sticker is widely used for barcode of food and cosmetics, and can also be used for labels of electronic products and mechanical products under special environment.
