PVC Self-adhesive Sticker

PVC sticker ‘ structure

1. The surface material. Is the carrier of sticker content, tissue paper back coating is adhesive. Transparent polyvinyl chloride (PVC), electrostatic polyvinyl chloride (PVC),

2. Membrane material. Transparent polyester (PET), translucent polyester (PET), transparent directional stretched polypropylene (OPP), transparent polyvinyl chloride (PVC), white polyvinyl chloride (PVC), matt white polyvinyl chloride (PVC), synthetic paper, light gold (silver) polyester, matt gold (silver) polyester.

3. Adhesive. General super adhesion type, general strong adhesion type, frozen food strong adhesion type, general re-opening type, fiber re-opening type. On the one hand, it guarantees the proper adhesion between the bottom paper and the tissue paper, and on the other hand, it guarantees that the tissue paper is peeled off, and the paste has a strong paste.

4. Backing material. Release paper commonly known as "bottom paper", the surface is low surface energy of non-viscosity, the bottom paper has a separation effect on adhesive, so use it as the adhesive, to ensure that the surface paper can be easily peeled off from the bottom paper. Commonly used are white, blue, yellow glasine paper (glassine) or garlic paper (onion), kraft paper, polyester (PET), coated paper, polyethylene (PE).

Application

Common labels include drug labels, food labels, wine labels, battery labels, outer box labels, shampoo labels, bar codes, temporary labels of semi-finished products and so on.

1. It is mainly used for decorative decals on cars and motorcycles, logo text on trademark Windows, reflective film on highways and marks on containers, etc.

2. mainly paper and film, according to the application range of basic label and variable information label.

3. Variable information label: batch number, sequence code, bar code, production date, validity period, price, mailing process information processing, distribution, warehouse management, inventory data, etc.

Edit this section category by folding

Sticker can be divided into two categories: one is paper sticker, the other is film sticker.

1, paper sticker is mainly used for liquid washing products and popular personal care products;Thin film materials are mainly used in high - end chemical products. At present, popular personal care products and household liquid washing products occupy a large proportion in the market, so the corresponding paper materials are used more.

PVC adhesive material has transparent, bright milky white, matt milky white water resistance, oil resistance and chemical products and other important properties of the product label, used for toilet supplies, cosmetics, electrical products, especially suitable for high-temperature products information label.

PVC shrink film sticker is suitable for battery label.

Chemical synthetic paper is used to label high grade products and environmental protection products.

The advantages of folding edit section

Compared with the traditional stickers, stickers with no brush glue, no paste, no dip in water, no pollution, save labeling time and other advantages, wide range of application, convenient and fast. All kinds of self-adhesive label can be used in a normal paper label is not up to the material, it can be said that the non-drying label is a kind of universal label, the non-drying label printing compared with the traditional printed matter printing has the very big difference, the non-drying label is usually on the labeling linkage machine printing processing, process one more time to complete, such as graphic printing, die cutting, waste, cutting Zhang Hefu volume, etc. It can be seen that sticker on the printing process and printing equipment has higher requirements, so choose sticker should pay attention to:

According to the type, grade, quality, paste surface characteristics, use environment and user requirements, etc. If you want to use transparent polypropylene sticker made of stickers on the transparent bottle body can produce a sense of fashion without labels, can improve the level of goods, stimulate consumers' desire to buy. And PVC film flexibility, shrinkage, light impermeability, processing characteristics and labeling characteristics are very good, and bright colors, contrast, can attract people's attention, has the role of promotional goods.

The film sticker surface must be smooth and dense, uniform density, color consistent, good light transmission, to ensure that the film ink uniform, with a batch of printing color difference.

The adhesive sticker thickness should be uniform, strength indicators to be qualified. The printing pressure applied in the printing process is related to the adhesive thickness, if the thickness is not uniform, then the printing pressure is not uniform, will lead to the label print writing or ink color is deep and light. If the film strength is too poor, printing process film tension is difficult to control, will have a great impact on die cutting and exhaust.

In addition, adhesive labels should be smooth and roll tension even. Flatness is good, when printing can be correct delivery, operation, alignment and winding. Film rewinding tension should be uniform and appropriate, such as the tension is too small, film substrate relaxation, vertical and horizontal overprinter is not allowed; If the tension is too large, the base material transverse contraction, color registration is not stable, it is difficult to print.

5] film type adhesive label also has the characteristics of corrosion resistance, aging resistance, color proof, small shrinkage and expansion ratio. If corrosion resistance is poor, easy to aging, fading, then made of the label is not durable, will affect the sale and use of goods. If the contraction, expansion ratio is large, it will not only affect the printing accuracy, but also make the label in the use of deformation, affecting the sale and use of goods. In particular, the label of high-end goods, should try to avoid the product has not expired, and the label has aging embarrassing situation (including aging plastic and ink fading reasons). When necessary, aging resistance test should be carried out on plastics or labels to test their performance.

6 choose and sticker also want to be in effect, maintain a good viscosity.
