Adhesive label is a kind of composite material which is made of paper, film or special material, adhesive on the back and silicon base paper as protection paper. It is finished label after printing and die cutting. When applied, only peel off the bottom paper, press gently, can be pasted to the surface of various substrates, or can use the labeling machine in the production line to automatically label.
The structure of self-adhesive label is shown in the figure above, which is mainly composed of surface material, glue, silicone oil and base material.
1、Surface material
It is the carrier of the content of the self-adhesive label, and the back of the face paper is coated with adhesive. There are many kinds of surface materials that can be used, including coated paper, transparent polyvinyl chloride (PVC), electrostatic polyvinyl chloride (PVC), polyester (PET), laser paper, heat-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 (tevick / nylon) paper, etc Pearlescent paper, sandwich coated paper, thermal paper.
2、Coating material
General super viscosity type, general strong viscosity type, refrigerated food strong viscosity type, general re uncovering type, fiber re uncovering type. On the one hand, it can ensure the proper adhesion between the base paper and the face paper, on the other hand, it can ensure that the face paper can be peeled off and have strong adhesiveness with the paste.
4、Backing material
Release paper is commonly known as "backing paper". The surface is non sticky with low surface energy. Backing paper has an isolation effect on adhesive, so it is used as the attachment of face paper to ensure that the face paper can be easily stripped from the backing paper. Commonly used are white, blue, yellow grazin paper (glassine) or garlic paper (onion), kraft paper, polyester (PET), coated paper, polyethylene (PE).
There are two kinds of self-adhesive labels: one is paper type, the other is film type.
1、Paper self-adhesive labels are mainly used in liquid washing products and popular personal care products; Film materials are mainly used in high-grade daily 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.
2、PE, PP, PVC and some other synthetic materials are commonly used for film self-adhesive labels. The film materials mainly include white, Matt and transparent. As the printability of thin film is not very good, it is usually enhanced by corona treatment or coating. In order to avoid the deformation or tearing of some film materials in the process of printing and labeling, some materials will also undergo directional treatment and be stretched unidirectionally or biaxially. For example, BOPP materials after biaxially stretching are widely used in calendered writing paper, offset paper and multi-purpose label, which are used for information label and bar code printing label, especially for high-speed laser printing, Also suitable for inkjet printing.
The common ones are drug label, food label, wine label, battery label, outer box label, shampoo label, bar code, temporary label of semi-finished products, etc.
1、The film is mainly used for decorative decals on automobiles and motorcycles, logo words on trademark windows, reflective film on expressways, marks on containers, etc.
2、Based on paper and film, it can be divided into basic label and variable information label.
3、Variable information labels: batch number, sequence code, bar code, production date, validity period, price, information processing of mailing process, distribution, warehouse management, inventory data, etc.

2、Coating material
Transparent polyester (PET), translucent polyester (PET), transparent oriented polypropylene (OPP), translucent oriented polypropylene (OPP), transparent polyvinyl chloride (PVC), bright white polyvinyl chloride (PVC), matte white polyvinyl chloride (PVC), synthetic paper, bright gold (silver) polyester, matte gold (silver) polyester.
General super viscosity type, general strong viscosity type, refrigerated food strong viscosity type, general re uncovering type, fiber re uncovering type.
