Self-adhesive label, is an important embodiment of the company's image and brand, plays an important role in reflecting product quality and arousing consumers' desire to buy. 1, The structure of the sticker The surface material The surface material is the carrier of the content of the self-adhesive label, and the back of the surface paper is coated with adhesive. Surface material can be used in a very large number of materials, General component is coated paper, transparent polyvinyl chloride (PVC), static polyvinyl chloride (PVC), polyester (PET), laser paper, thermal paper, polypropylene (PP), polycarbonate (PC), kraft paper, fluorescent paper, gold paper, silver paper, synthetic paper, aluminum foil paper, fragile (security) paper, crepe paper, woven lable (tyvek/nylon) paper, pearl paper, copper layer Edition paper, thermal paper. Membrane material The film material is transparent polyester (PET), translucent polyester (PET), transparent directional tensile polypropylene (OPP), translucent directional tensile polypropylene (OPP), transparent polyvinyl chloride (PVC), light white polyvinyl chloride (PVC), matte white polyvinyl chloride (PVC), synthetic paper, light gold (silver) polyester, matte gold (silver) polyester. adhesive Adhesives include general super adhesive type, general strong adhesive type, refrigerated food strong adhesive type, general re-opening type, fiber re-opening type. Adhesives on the one hand to ensure that the base paper and the surface paper moderate adhesion, on the other hand to ensure that the surface paper is peeled off, but also with the paste has a strong adhesion. The bottom paper material Release paper is commonly known as the "base paper", the base paper has an isolation effect on adhesives, so it is used as the adhesive of the surface paper, to ensure that the surface paper can be easily peeled off the base paper. Commonly used are white, blue, yellow glassine paper or onion, kraft paper, polyester (PET), coated paper, polyethylene (PE).2, The material selection of adhesive Small self-adhesive, in many cases, is an important reflection of the company's image and brand, which plays an important role in reflecting product quality and arousing consumers' purchase desire. So choose the label, or sticker label, what are the matters needing attention? Matters needing attention when choosing sticker label materials: (1) For cylindrical bottles, especially those with a diameter less than 30MM, choose the materials carefully. (2) if the label size is too large or too small, attention should be paid to the actual test. (3) if the paste is irregular surface or even spherical, there are specific considerations for the type of label material, thickness and adhesive. (4) some rough surfaces such as corrugated boxes will affect the labeling, corrugated box surface varnish will also have an impact. (5) Automatic labeling machine label, labeling test can be carried out if necessary. (6) even if the label is labeled at room temperature, we should pay attention to whether high temperature is experienced during export transportation and use. (7) water or oil environment will affect the characteristics of adhesives, should pay attention to the label of the environment and temperature. (8) soft PVC surface sometimes have plasticizer seepage, special attention should be paid to the selection of appropriate adhesive.Packing Details Pack twice for double protection.
