The self-adhesive labels commonly used in bar code printers consist of three parts: bottom paper, face paper, and adhesives that are both bonded together. The surface of the bottom paper is oily and has an insulating effect on the adhesive, so it is used as an attachment to the tissue so that the tissue can be easily peeled off from the backing paper.
The bottom paper is divided into plain paper and GLASSINE backing paper. Ordinary bottom paper has rough texture, large thickness, yellow, white, etc., commonly used adhesive backing paper for the printing industry is an economical yellow bottom paper; GLASSINE bottom paper has a dense and uniform texture. Good internal strength and transparency are common materials used to make bar codes. Its commonly used white, blue.
Paste paper is the carrier of the label printing content, divided into coated paper, thermal paper, PET, PVC and other types according to the material. The back of the tissue paper is an adhesive, which on the one hand ensures the proper adhesion of the base paper and the tissue paper, and on the other hand ensures that the tissue paper has a strong adhesiveness to the adhesive material after peeling off.
PET Advanced Label Paper
PET is the English abbreviation of polyester film, in fact it is a kind of polymer material. PET has good hardness and brittleness, common colors are ADB, Asian white, bright white. Due to its excellent media properties, PET has good properties such as anti-fouling, scratch-resistance, and high-temperature resistance. It is widely used in many special occasions. Such as electronic components, mobile phone batteries, electrical products, automotive parts, chemicals, outdoor advertising, textile printing and other fields;
Coated (Snow Copper) Labels
Barcode printing commonly used materials, its thickness is generally about 80g. Widely used in supermarkets, retail, clothing tag, logistics labels, inventory management, railway tickets, pharmaceutical labels, product printing and other bar code printing applications;
PVC advanced label paper
PVC is the abbreviation of vinyl, it is also a kind of polymer material, common colors are white, pearl white. PVC and PET have similar properties. It has better flexibility than PET, and has a soft feel. It is often used in jewelry, jewelry, watches, electronics, and metal industries. However, the poor degradability of PVC has a negative impact on environmental protection. Some developed countries in the world have begun to develop alternative products in this area.
Thermal Paper
Thermal paper is a highly heat-sensitive coated paper. High-sensitivity surface materials can be applied to low-voltage print heads, resulting in minimal wear on the print head. Thermal paper is a kind of hot paper that is specially used in electronic scales and cash registers. The simplest method for testing thermal paper is to use a fingernail to force it across the paper and leave a black scratch. Thermal paper is suitable for cold storage, freezer and other shelves.
Washing water
Mainly used in the apparel industry.
