What is a sticker?

Self-adhesive is a composite material with paper, film or special material as the fabric, adhesive (self-adhesive) on the back, and silicon-coated protective paper as the base paper.

Self-adhesive structure

1. Face material: It is the carrier of the self-adhesive label content, and the back of the face paper is coated with adhesive. There are many materials that can be used for surface materials, generally divided into coated paper, transparent polyvinyl chloride (PVC), electrostatic polyvinyl chloride (PVC), polyester (PET), laser paper, temperature-resistant paper, polypropylene (PP), Polycarbonate (PC), kraft paper, fluorescent paper, gold-plated paper, silver-plated paper, synthetic paper, aluminum foil paper, fragile (anti-counterfeiting) paper, textured paper, cloth label (Tavic/nylon) paper, pearl paper, Sandwich coated paper, thermal paper.

2. Film material: transparent polyester (PET), translucent polyester (PET), transparent oriented stretched polypropylene (OPP), translucent oriented stretched polypropylene (OPP), transparent polyvinyl chloride (PVC), bright White polyvinyl chloride (PVC), matt white polyvinyl chloride (PVC), synthetic paper, shiny gold (silver) polyester, matt gold (silver) polyester.

3. Adhesives: general-purpose super-viscosity, general-purpose strong-viscosity, refrigerated food strong-viscosity, general-purpose re-opening type, and fiber-re-opening type. On the one hand, it ensures proper adhesion between the bottom paper and the face paper, and on the other hand, it ensures that the face paper is peeled off, and it can have strong adhesion to the paste.

4. Bottom paper material: Release paper is commonly known as "bottom paper". The surface is non-sticky with low surface energy. The bottom paper has an isolation effect on the adhesive. Therefore, it is used as the attachment of the facial paper to ensure that the facial paper can be easily removed from the surface. Peel off the bottom paper. Commonly used are white, blue, yellow glassine or onion, kraft paper, polyester (PET), coated paper, and polyethylene (PE).

3: Use glue type: general super sticky type, general strong sticky type, refrigerated food strong sticky type, general re-opening type, fiber re-opening type.

4: Use bottom paper: white, blue, yellow glassine paper (or garlic paper onion) kraft paper polyester PET coated paper polyethylene polyethylene.

Self-adhesive label category

There are two types of self-adhesive labels: one is paper-based self-adhesive labels, and the other is film-based self-adhesive labels.

1. Paper-based self-adhesive labels are mainly used for liquid washing products and popular personal care products; film materials are mainly used for medium and high-end daily chemical products. At present, the popular personal care products and household liquid washing products on the market occupy a large proportion, so the corresponding paper materials are used more.

2. Film type self-adhesive labels are commonly used in PE, PP, PVC and some other synthetic materials. The film materials are mainly white, matte, and transparent. Since the printability of the film material is not very good, it is generally treated with corona or by adding a coating on its surface to enhance its printability. In order to avoid deformation or tearing of some film materials during the printing and labeling process, some materials will also undergo directional treatment, uniaxial stretching or biaxial stretching, for example, the application of biaxially stretched BOPP materials is quite common.

Calendered writing paper, offset paper label Multi-purpose label paper, used for information label, barcode printing label, especially suitable for high-speed laser printing, but also suitable for inkjet printing.

The high-performance adhesive is suitable for a variety of surfaces. After processing and printing, it is used for product identification.

Application areas of self-adhesive labels

Packaging industry: mark labels, postal parcels, letter packaging, shipping goods labels, envelope address labels;

Commodity industry: price label, product description label, shelf label, barcode label, drug label;

Chemical industry: labeling of paint materials, packaging labeling of gasoline engine oil products, and labeling of various special solvent products;

Electronic and electrical labels for the electrical and electronic industry: There are many durable self-adhesive labels affixed to various electrical appliances. These labels have a large unit area and a large number. In addition, self-adhesive labels are also widely used as industrial products (computers, etc.) indicating signs, which has also driven the demand for self-adhesive labels.

Logistics labels in the logistics industry: In recent years, the logistics industry is emerging in my country, and modern logistics has more and more demands for variable information printing labels, such as storage and transportation labels, luggage labels, and supermarket labels.

Pharmaceutical labels for the pharmaceutical industry: Self-adhesive labels have been increasingly used in pharmaceutical packaging. With the over-the-counter sales of over-the-counter drugs, pharmaceutical manufacturers and consumers pay more attention to pharmaceutical packaging, which will, to a large extent, encourage pharmaceutical manufacturers Speed up the transition from traditional labels to self-adhesive labels.

Self-adhesive sticker is a kind of multi-way advertising material widely used in the advertising industry. It works best with the sticky sticker engraving machine. The products carved out are widely used in light boxes, signboard production (mounting), and body advertising. Production, permanent signs, signs, computer-cut patterns, window patterns, exhibition boards, etc.

The adhesive of this product is acrylic solvent-based pressure-sensitive adhesive with excellent adhesion. The polymer calendered polyethylene base rubber has the characteristics of multi-color, strong color retention and uniform color, and has good weather resistance and pollution resistance. It has good shrink resistance and a service life of more than three years. It is a cost-effective method for ordinary facade decoration.

Other industries: anti-counterfeiting labels, encryption labels, anti-theft labels.
