SELF ADHESIVE LABEL
Compared with the traditional label, the self-adhesive label has the advantages of no need to brush glue, no need to paste, no need to dip in water, no pollution, saving labeling time, wide application range, convenience and quickness. Sticker is a kind of material, also known as self-adhesive label material, which is a composite material with paper, film or other special materials as the fabric, adhesive coated on the back, and silicon-coated protective paper as the backing paper. After printing, die-cutting and other processing, it becomes a finished label.
1. Paper Substrate
Paper Substrate are divided into: offset paper, coated paper, glass cardboard, laser paper, kraft paper, fluorescent paper, gold-plated paper, aluminum foil paper, fragile (anti-counterfeiting) paper, silver-plated paper, masking paper, cloth label (Tyvek/nylon) paper, pearlescent paper, sandwich coated paper, and variable information paper.
2. Film Substrate
Film substrates are divided into: transparent polyvinyl chloride (PVC), polyester (PET), polypropylene (PP), polycarbonate (PC), synthetic paper, PS, PE, shape memory anti-counterfeiting materials (SMP) and so on.
☀How to use
Just peel it from the backing paper and press it lightly to stick it on the surface of various substrates, or use the labeling machine to label automatically on the production line.

☀Adhesive Universal Super Viscous,
Universal Strong Viscous, Refrigerated Food Strong Viscous, Universal Uncover, Fiber Uncover. On the one hand, it ensures the proper adhesion between the bottom paper and the surface paper, and on the other hand, it ensures that the surface paper can have strong adhesion with the adhesive after being peeled off.
☀Bottom material Release paper
commonly known as "bottom paper", has a non-adhesive surface with low surface energy, and the bottom paper has an isolation effect on the adhesive, so it is used as the attachment of the surface paper to ensure that the surface paper can be easily peeled off from the bottom paper. Commonly used are white, blue, yellow glassine or onion, kraft paper, polyester (PET), coated paper, polyethylene (PE).
It is mainly used in liquid washing products and popular personal care products. Film materials are mainly used in medium and high-grade daily chemical products. At present, popular personal care products and household liquid washing products account for a large proportion in the market, so the corresponding paper materials are used more.
ommonly used PE, PP, PVC and other synthetic materials, film materials are mainly white, matte, transparent three. Because that printability of the film material is not very good, the film material is generally subject to corona treatment or a coating is added to the surface to enhance the printability. In order to avoid deformation or tearing of some film materials in the process of printing and labeling, some materials will also undergo directional treatment for unidirectional stretching or bidirectional stretching. For example, BOPP materials with bidirectional stretching are widely used in calendering writing paper, offset paper label and multi-purpose label paper, which are used for information labels and bar code printing labels, especially for high-speed laser printing. It is also suitable for inkjet printing

█Features and advantages
Has the advantages of no need of brushing glue, no need of paste, no need of dipping in water, no pollution, labeling time saving, wide application range, convenience and quickness. All kinds of self-adhesive labels can be applied to materials that ordinary paper labels are not competent for. It can be said that self-adhesive labels are universal labels. Compared with the printing of traditional printed matter, self-adhesive label printing is very different. Self-adhesive labels are usually printed and processed on the label linkage machine, and many processes are completed at one time, such as graphic printing, die-cutting, waste discharge, sheet cutting and rewinding.
(1) According to the type, grade and quality of the labeling object, the characteristics of the pasting surface, the use environment and the requirements of the user. If the label made of polypropylene self-adhesive label with good transparency is pasted on the transparent bottle body, the fashion feeling of no label can be produced, the grade of the commodity can be improved, and the purchase desire of consumers can be stimulated. The flexibility, shrinkage, opacity, processing characteristics and labeling characteristics of PVC film are very good, and the color is bright, which has the function of propaganda and promotion of commodities.
(2) The surface of film self-adhesive labels must be smooth and dense, with uniform density, consistent color and good light transmittance, so as to ensure that the film absorbs ink evenly and the color difference of the same batch of prints is small.
(3) The thickness of the self-adhesive label should be uniform and the strength index should be qualified. The printing pressure applied in the printing process is related to the thickness of the sticker. If the thickness is uneven, the printing pressure is also uneven, which will cause the handwriting or ink color of the label print to be different. If the film strength is too poor, the tension of the film in the printing process is difficult to control, which will have a great impact on die-cutting and waste discharge.
(4) The self-adhesive label should be flat and the rewinding tension should be uniform. Good flatness enables correct conveying, running, registration and winding during printing. The rewinding tension of the film should be uniform and appropriate, if the tension is too small, the film substrate is loose, and the vertical and horizontal overprint is not accurate; If the tension is too large, the substrate will shrink horizontally, the color register will be unstable, and it will be difficult to print normally.
(5) Film self-adhesive labels should also have the characteristics of corrosion resistance, aging resistance, no fading, small shrinkage and expansion ratio. If the corrosion resistance is poor, it is easy to age and fade, the label made is not durable, and it will also affect the sale and use of goods. If the shrinkage and expansion ratio is large, it will not only affect the overprint accuracy during printing, but also deform the label during use, affecting the sale and use of goods. Especially for the labels of high-end goods, we should try our best to avoid the embarrassing situation that the goods are not expired and the labels are aging (label aging includes plastic aging and ink fading). If necessary, the aging resistance test shall be carried out on the plastic or label to test its service performance.
(6) The self-adhesive labels purchased should also maintain good stickiness within the validity period.
█Field of application
☀Daily chemical industry
Sticker labels are now widely used in the daily chemical industry. It is understood that at present, more than 30% of domestic daily chemical products use self-adhesive labels as labels. According to statistics, self-adhesive labels in the domestic market are still growing rapidly in the daily chemical industry and are more widely used. Label materials will also develop in a high-level and diversified direction.
Daily chemical products have high added value, so there are many brands and fierce competition. Consumers choose a commodity in a dazzling array of commodities, product packaging is the key factor to attract consumers, and the most important part of the packaging of daily chemical products is the label, which shows that the delicacy of the label plays a key role. The self-adhesive label can perfectly reflect the requirements of the labe
With the promulgation of GMP certification standards, the pharmaceutical industry has higher requirements for the standardization of drug packaging, whether for the hygiene or aesthetics of packaging, are making further requirements. On the premise that the adhesive material meets the hygienic standard, the self-adhesive label can well meet the needs of drug packaging. On the one hand, the production requirements of the pharmaceutical industry are relatively high, the flow operation speed is fast, many bottles need automatic labeling to meet the requirements; On the other hand, the self-adhesive material is suitable for various printing methods, and has the effects of clear pictures and texts, neatness and strong adhesion, so that the self-adhesive label can meet the requirements of the market for drug packaging. In the period of vigorous development of OTC, consumers must have higher and higher requirements for drug packaging. They hope that the label is not only a description, but also a brand symbol. At the same time, pharmaceutical products also attach great importance to anti-counterfeiting, self-adhesive labels have a variety of materials to choose from, such as fragile paper, font anti-counterfeiting labels and so on.
Nowadays, electronic appliances have spread to every corner of people's lives, and the further popularization of household appliances and communication tools has made the development of the electronic industry unprecedented.
☀Supermarket and logistics industry
With the development of market economy and the acceleration of commodity circulation, China's retail industry is developing at an extraordinary speed. According to the statistics of the National Bureau of Statistics, there are 1232 chain enterprises above designated size in China's commercial retail and catering industries, with a total of 34551stores. In the future, the market demand for variable information printing labels will be more and more, such as fresh food in supermarkets, because of its fast circulation and huge profits, has always been a "battleground", so thermal labels have a lot of room for development.For example, luggage labels, supermarket price labels, storage and transportation labels, etc., are now widely used. In some logistics developed countries in Europe, self-adhesive labels for variable information printing have accounted for more than 40% of the total market demand for self-adhesive labels. In China, this market has just started, and the annual per capita consumption is very small. Foreign retail giants and local private enterprises all want to become bigger and stronger as the future development direction. Logistics industry is a new industry, and many large and medium-sized cities in China hope to play the role of logistics center. Bar code is used for production management and logistics management, and bar code self-adhesive label is the most basic requirement. While more enterprises taste the benefits of bar code management, it will also bring unlimited business opportunities to the self-adhesive industry. With the rapid development of the logistics industry, there will be a huge demand for variable information self-adhesive labels in the market.
The characteristics of self-adhesive labels have the application conditions in the anti-counterfeiting industry. The earliest anti-counterfeiting label in China appeared in the mid-1980s, and its application fields include wine, food, medicine, health care products, cosmetics, children's products, toys, clothing tags, shoe labels, computer software and hardware products, sports goods, automotive parts, agricultural materials, etc. The use of self-adhesive anti-counterfeiting labels on commodities has a broad market development space in China.
