Self-adhesive labels have the advantages of no brushing, no paste, no drowning, no pollution, and saving labeling time compared with traditional labels. The application range is wide and convenient. All kinds of self-adhesive labels can be applied to materials that the general paper label can not be competent. It can be said that self-adhesive label is a kind of universal label. The printing of self-adhesive labels has a great deal compared with the printing of traditional prints. The big difference is that sticker labels are usually printed and processed on label-linked machines, and multiple processes are completed at once, such as graphic printing, die-cutting, waste disposal, cutting, and rewinding. Visible, self-adhesive labels have higher requirements for the printing process and printing equipment.
The label application field is quite extensive:
Commonly used barcode labels include drug labels, food labels, wine labels, battery labels, carton labels, shampoo labels, barcode labels, semi-finished product temporary labels, and the like. It is mainly used as a film and is mainly used for decorative decals on automobiles and motorcycles, logotypes on trademark windows, reflective films on highways, and marks on containers. Mainly paper and film, according to the scope of application is divided into basic labels and variable information labels. Variable information labels: lot number, order code, bar code, date of manufacture, expiry date, price, mailing process information processing, distribution, warehouse management, inventory data, etc.
Application area:
1, daily chemical industry
Non-stick labels are now widely used in the daily-use chemical industry. It is understood that at present, the proportion of domestic daily chemical products using self-adhesive labels as labels exceeds 30%. According to statistics, the current domestic market's self-adhesive labels are still maintaining a momentum of rapid growth in the daily chemical industry, and are getting better. For a wide range of applications, label materials will also develop in a high-level and diversified direction.
2, pharmaceutical industry
As the country promulgates GMP certification standards, the pharmaceutical industry has higher requirements on the standardization of pharmaceutical packaging. Whether it is for packaging hygiene or aesthetics, it is making further demands. Self-adhesive labels can meet the needs of pharmaceutical packaging well under the premise of achieving hygienic standards for adhesive materials. On the one hand, the pharmaceutical industry has relatively high production requirements, and the flow rate is fast. Many drug bottles need to be automatically labelled to meet the requirements when labeling; on the other hand, self-adhesive materials are suitable for various printing methods, with clear graphics and neat The strong sticking effect makes the self-adhesive labels meet the requirements of the market for pharmaceutical packaging. In the period of vigorous development of OTC, consumers are increasingly demanding the packaging of pharmaceuticals. They hope that the label is not only a description, but also a sign of a brand. At the same time, pharmaceutical products also attach great importance to anti-counterfeiting, there are a variety of stickers available for the selection of materials, such as easy shredding, fonts, anti-counterfeiting labels.
3, the electronics industry
Electronic devices have now spread to every corner of people's lives. The further popularization of household appliances and communication tools has made the development of the electronics industry unprecedented.
Adhesive labels are very popular in this area not only because they can be affixed, printed, and designed, but more importantly, electronic products need to use labels to achieve specific effects. For example, the texture of the label is firm and can be well matched with the electrical appliance, or the label can resist corrosion and high temperature resistance of the external environment. Often in different parts of an electrical product, several types of label materials are needed. The tremendous development of the electronics industry, especially in South China and East China, has a relatively large proportion of exports, and it also drives the consumption of self-adhesive label materials. The main area. As in other fields, label materials used in the electronics industry generally have relatively high requirements. Many multinational companies have their own stringent testing methods such as stickiness, scratch resistance, and temperature resistance. But in general, many companies have asked for UL certification for label materials.
The classification of stickers:
Stickers can be broadly divided into two types: one is a paper sticker, and the other is a film sticker.
1, paper stickers are mainly used for liquid washing products and popular personal care products; film materials are mainly used in high-end products on the day.
2, film adhesive labels commonly used PE, PP, PVC and other synthetic materials, film materials are mainly white, matt, transparent three. Because the printability of thin film materials is not very good, corona treatment is generally performed or a coating is added on its surface to enhance its printability. In order to prevent some film materials from being deformed or torn during the printing and labeling process, some of the materials will also undergo directional processing for uniaxial or biaxial stretching. For example, biaxially oriented BOPP materials are quite common.
With adhesive introduction:
Self-adhesive is a kind of material, also called self-adhesive label material. It is a kind of composite material with paper, film or other special materials as the fabric, adhesive on the back, and silicon-coated protective paper as the backing paper.
Self-adhesive is a general name for materials of this nature. In China, many people conflate stickers with labels/labels. In fact, they are essentially different. In English, there is no word “stickerâ€. Only the label and the labeling (labeling), the label of the general foreigner's appellation, the domestic appellations are varied, and the more common ones are: stickers, labels, labels, stickers. , self-paste and so on.
