Practical application of self-adhesive labels

self adhesive labels are also called self-adhesive labels, timely stickers, instant stickers, pressure-sensitive paper, etc. they are a composite material with paper, film or special materials as the fabric, adhesive coated on the back, and silicon coated paper as the protective paper, and become finished labels after printing, die cutting and other processing. When applied, just peel it off from the backing paper and press it gently to stick it to the surface of various substrates, or use the labeling machine to automatically label it on the production line

compared with traditional labels, self-adhesive labels have the advantages of no glue, no paste, no dipping in water, no pollution, saving labeling time and so on. They have a wide range of applications and are convenient and fast. All kinds of self-adhesive labels can be applied to materials that general paper labels are not competent for. It can be said that self-adhesive labels are a universal label. The printing of self-adhesive labels is very different from the printing of traditional printed materials. Self-adhesive labels are usually printed and processed on label linkage machines, and multiple processes are completed at one time, such as graphic printing, die cutting, waste discharge, sheet cutting and rewinding. It can be seen that self-adhesive labels have high requirements for printing technology and printing equipment

self adhesive labels are widely used:

bar code labels are commonly used in drug labels, food labels, wine labels, battery labels, outer box labels, shampoo labels, bar code labels, temporary labels of semi-finished products, etc. Mainly film, mainly used for decorative decals on cars and motorcycles, logo words on trademark windows, reflective films on highways, marks on containers, etc. Based on paper and film, it is divided into basic labels and variable information labels according to the scope of application. Variable information labels: batch number, sequence code, bar code, production date, expiration date, price, information processing during mailing, distribution, warehouse management, inventory data, etc

application field:

1, daily chemical industry

non thousand glue labels have been widely used in daily chemical industry. It is understood that at present, more than 30% of domestic household chemical products use self-adhesive labels as labels. According to statistics, at present, self-adhesive labels in the domestic market still maintain a rapid growth momentum in the household chemical industry, and are more widely used. Label materials will also develop to a high-level and diversified direction

2, the sales volume of medicine in December 2017 was 69 million euros. The pharmaceutical industry

with the promulgation of GMP certification standards, the pharmaceutical industry has higher requirements for the standardization of drug packaging, and is making further requirements for both the hygiene and aesthetics of packaging. On the premise that the adhesive materials meet the hygienic standards, self-adhesive labels can well meet the needs of drug packaging. On the one hand, the production requirements of the pharmaceutical industry are relatively high, and the flow operation speed is fast. Many drug bottles need to be automatically labeled to meet the requirements when labeling; On the other hand, self-adhesive materials are suitable for various printing methods, with clear graphics and text, neat and strong adhesive effect, so that self-adhesive labels can meet the requirements of the market for drug packaging. During the booming period of OTC, consumers' requirements for drug packaging must be higher and higher. They hope that the label is not only a description, but also a brand logo. 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, etc

3, the electronic industry

electronic devices have now spread all over every corner of people's lives. The further popularization of household appliances and communication tools has made the development of the electronic industry unprecedented

sticker is very popular in this field, not only because it can be pasted, printed and designed, but also because electronic products need to use labels to achieve some specific effects. For example, the label has a strong texture and can be well matched with electrical appliances, or the label can resist the corrosion and high temperature of the external environment. Energy conservation and emission reduction are often achieved in different parts of an electrical product, which requires several forms of label materials. The huge development of the electronic industry, especially in South and East China, accounts for a large proportion of exports, which is the main area driving the consumption of self-adhesive label materials. Like other fields, label materials used in the electronic industry generally have high requirements. Many multinational companies have their own strict testing methods, such as measuring viscosity, scratch resistance, temperature resistance, etc. But generally speaking, many enterprises have put forward requirements for label materials to have UL certification. The classification of

self-adhesive labels:

self-adhesive labels are roughly divided into two types: one is paper self-adhesive labels, and the other is film self-adhesive labels

1, paper self-adhesive labels are mainly used for liquid washing products and popular personal care products; Thin film materials are mainly used in medium and high-end daily chemical products

2, PE, PP, PVC and other synthetic materials are commonly used for film self-adhesive labels. Film materials mainly include white, matte and transparent, so as to confirm whether the bits converted into numbers are 1 or 0 bit by bit. Since the printability of thin film materials is not very good, corona treatment or coating on its surface are generally used to enhance its printability. In order to avoid the deformation or tearing of some film materials in the process of printing and labeling, some materials will be directionally treated and subjected to unidirectional stretching or biaxial stretching. For example, BOPP materials subjected to biaxial stretching are widely used

introduction of self-adhesive:

self adhesive is a kind of material, also known as self-adhesive label material. It 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 base paper

sticker is a general term for materials with this nature. In China, many people confuse sticker with label/label. In fact, they are essentially different. In English, there is no word sticker, only label and labeling. Generally speaking, the appellation labels of foreigners are diverse, and the more common ones are: sticker, label, label, sticker, Self adhesive sticker, etc
