What are the structural characteristics of self-adhesive mat

　　First, the structure

　　1. Face material: It is the carrier of the self-adhesive label content, and the back of the paper is coated with adhesive. The surface material can be used in a wide variety of materials, generally divided into coated paper, transparent polyvinyl chloride (PVC), electrostatic polyvinyl chloride (PVC), polyester (PET), laser paper, temperature resistant paper, polypropylene (PP), Polycarbonate (PC), kraft paper, fluorescent paper, gold-plated paper, silver-plated paper, synthetic paper, aluminum foil paper, fragile (anti-counterfeit) paper, textured paper, cloth label (Tevek/nylon) paper, pearl paper, Sandwich coated paper, thermal paper.

　　2, film material: transparent polyester (PET), translucent polyester (PET), transparent oriented stretch polypropylene (OPP), translucent oriented stretch polypropylene (OPP), transparent polyvinyl chloride (PVC), There are light white polyvinyl chloride (PVC), matt white polyvinyl chloride (PVC), synthetic paper, polished gold (silver) polyester, matt gold (silver) polyester.

　　3, adhesive: general super-adhesive, general-purpose strong-adhesive, refrigerated food strong adhesive type, universal re-opening type, fiber re-opening type. On the one hand, it ensures the proper adhesion of the base paper and the facial tissue, on the other hand, it ensures that the facial tissue is peeled off and has a firm adhesiveness with the sticker.

　　4, the bottom paper material: release paper commonly known as "bottom paper", the surface is low surface energy non-sticky, the bottom paper has a barrier effect on the adhesive, so use it as the attachment of the paper to ensure that the paper can be very Easy to peel off from the liner. Commonly used are white, blue, yellow glassine or onion, kraft paper, polyester (PET), coated paper, polyethylene (PE).

　　Second, the characteristics

　　The so-called self-adhesive printing is a process of transferring ink and the like through a printing plate to a surface of a printing material on which a backing layer is pre-coated under a certain pressure. Compared with ordinary printing, stickers have the following characteristics:

　　The investment is small and the effect is quick. Self-adhesive prints are mostly trademarks and stickers, which have a small format, fast printing speed and less waste.

　　Flexible printing method. Stickers are not limited by the printing method, and traditional printing houses can be printed by offset presses or screen printers.

　　It has many functions, and its self-adhesive is widely used in food, cosmetics, and barcodes. It can also be used as a signage in special environments such as electronic products and mechanical products.
