1. Face material:
It is the carrier of the content of the self-adhesive label, and the back of the tissue is coated with adhesive. There are many materials that can be used for surface materials, generally divided into coated paper, transparent polyvinyl chloride (PVC), electrostatic polyvinyl chloride (PVC), polyester (PET), laser paper, heat-resistant paper, polypropylene (PP), Polycarbonate (PC), kraft paper, fluorescent paper, gold-plated paper, silver-plated paper, synthetic paper, aluminum foil paper, fragile (anti-counterfeiting) paper, textured paper, cloth label (Tyvik/nylon) paper, pearl paper, Sandwich art paper, thermal paper.
2. Membrane material:
Transparent polyester (PET), translucent polyester (PET), transparent oriented stretch polypropylene (OPP), translucent oriented stretch polypropylene (OPP), transparent polyvinyl chloride (PVC), bright white polyvinyl chloride (PVC), matte white polyvinyl chloride (PVC), synthetic paper, glossy gold (silver) polyester, matte gold (silver) polyester.
General super sticky type, general strong sticky type, refrigerated food strong sticky type, general reopening type, fiber reopening type. On the one hand, it guarantees the proper adhesion of the bottom paper and the facial paper; on the other hand, it guarantees that after the facial paper is peeled off, it also has a strong adhesive property with the sticker.
4. Backing material:
The release paper is commonly known as "backing paper", and the surface is non-sticky with low surface energy. The backing paper has an isolation effect on the adhesive, so it is used as an attachment to the top paper to ensure that the top paper can be easily peeled off the bottom paper Down. Commonly used are white, blue, yellow glassine or onion, kraft paper, polyester (PET), coated paper and polyethylene (PE).
