Thermal paper adhesive material is a special coated processing paper, its appearance is similar to ordinary white paper. The surface layer of thermal paper is smooth, which is made of paper as a paper base, coated with a layer of thermal color layer, which is coated on the surface of the paper. The color layer is composed of adhesives, color developing agents, colorless dyes (or dark dyes), and is not separated by microcapsules.

The color layer is composed of adhesives, color developing agents, colorless dyes (or dark dyes), and is not separated by microcapsules. The chemical reaction is in a "latent" state. When the thermal paper meets the hot print head, the color developer at the print head and the colorless dye react chemically and change color to form an image and text. When the thermal paper is placed in an environment above 70 ° C, the thermal coating will begin to change color.
General thermal paper is only used for occasional transmission or issuance of information, and can not be stored for a long time. The preservation of sensitive paper is closely related to the preservation environment of thermal paper. If the sun is exposed and the temperature exceeds 30 ° C, it can only be stored for about ten days, therefore, the shelf life of thermal paper storage at different ambient temperatures is not the same.
Usually, the storage life of thermal paper is only 2 to 3 years, or even only a few months. Thermal paper with long storage life is a long-acting thermal paper. At present, its storage conditions are good (avoid high temperature and humidity, sun exposure, avoid contact with solvents, plasticizers, etc.) for more than 10 years.
The storage time of three thermosensitive paper is much longer than that of single thermosensitive paper, and the storage time of single thermosensitive paper is generally about half a year to half a month, but the storage time of three thermosensitive paper is as long as one year or even 2-3 years due to its own properties.
The difference between three thermosensitive paper materials and single thermosensitive paper materials:
Single heat-resistant paper label (waterproof) : generally use ordinary materials, clear printing, can be simple waterproof, basically meet the requirements of ordinary retail, bar code printing, logistics and transportation.
Three anti-thermal paper (waterproof, oil-proof, anti-wear) : the use of special surface material, with three anti-corrosion function (waterproof, oil-proof and anti-wear), the glue is also different, three anti-thermal paper is used hot melt adhesive, the initial viscosity is better, can apply to some surface is not very flat labeling base surface.
Thermal paper adhesive materials common glue is divided into, water glue, hot glue, frozen glue, movable glue.
1. Water glue: It is a universal adhesive suitable for paper surface material, with low initial viscosity and high final viscosity. Suitable for a variety of substrates (plastic, glass and metal containers).
2. Hot glue: universal permanent rubber-based adhesive, the initial viscosity and final viscosity are high, and it has excellent performance on many packaging materials.
3. Freeze glue: As the name suggests, it is an adhesive that can resist low temperature. Adhesive for use in low temperature and refrigerated environments. It has good performance on most substrates, such as paper, cartons, and films.
4. Removable adhesive: universal removable acrylic latex, suitable for various temperatures, good initial adhesion of removable adhesive, can be cleanly stripped from most of the substrate, no residual glue.
The collocation of glue is mainly selected according to the paste, the use environment and the use. Only the right is the best.

How to judge the thermal label material is good or bad, here to teach you three small methods:
1. Look at the appearance of the paper
First of all, we can judge its quality by looking at the appearance, when observing the appearance of thermal printing paper, we can first see whether its color is white, if the color is too white, it means that the paper adds a lot of phosphor, and it is to look at the finish of the paper, observe whether the whole paper looks uniform, if the surface is not uniform, It shows that when the heat sensitive layer and protective layer are not good enough, the quality of the paper is not good enough.
2. Grill it on fire
If you can't judge by observation, you can bake the back of the paper with fire, if the color of the paper is brown after heating, it means that the quality of the thermal paper is not good and the storage time is short. If the color is black and green, and the color is uniform, it indicates that the quality of the paper is good and can be stored for a long time.
3. Comparison and identification of sunlight exposure
The printed paper is daubed with a highlighter and placed in the sun (which can speed up the reaction of the heat-sensitive coating to light). Which paper turns black the fastest indicates the shorter time it can be stored.
Therefore, as long as the preservation method is proper, the quality of the purchased label paper is not too bad, and the basic preservation of a year or half is no problem, so there is no need to worry too much about such problems.
Thermal Paper Self Adhesive Material Suitable for milk tea shops, supermarkets, clothing, logistics, express, shops and other industries, waterproof, oil, alcohol and long storage time.
