What are the raw materials of three heat-sensitive labels?

The raw materials of three heat-sensitive labels mainly include the following parts:

First, thermal paper substrate

Composition: The thermal paper substrate is mainly composed of toner, fiber and glue. These components together form the basic structure of the thermal paper, so that it has the ability to sense the thermal coating, so as to ensure the clarity and stability of the printed result.

Second, the photosensitive layer

Material: The sensitive layer is a key factor in determining the environment and quality of the three heat-resistant label paper. It is usually formed from compounds such as PU (polyurethane), PVDC (polyvinylidene chloride), or PET (polyethylene terephthalate). These materials have good waterproof, anti-fouling and other characteristics, which can effectively improve the durability and protective performance of label paper.

Third, coating

Function: The coating is an important part of the three heat sensitive label paper, it can be customized according to different needs. On the premise of ensuring the characteristics of waterproof and anti-fouling, the coating can also increase the characteristics of high temperature and oil resistance of the label paper. This allows the three heat sensitive label paper to adapt to a wider range of use environments and conditions.

Fourth, other auxiliary materials

Hot melt adhesive: The three heat-sensitive self-adhesive label paper generally uses hot melt adhesive as its paste layer. The viscosity of this glue is much stronger than that of ordinary heat-proof paper, and it is more suitable for labeling base surfaces with uneven surfaces, ensuring that labels can be firmly pasted on various materials.

In summary, the raw materials of the three thermal label paper include thermal paper substrate (carbon powder, fiber, glue), sensitive layer (PU, PVDC, PET and other compounds), coating and hot melt adhesive and other auxiliary materials. These raw materials together constitute the high-quality printing media of the three heat-resistant label paper, so that it has excellent waterproof, oil resistance, high temperature resistance and other characteristics, suitable for outdoor, industrial and logistics and other occasions.

In addition, it is worth noting that with the promotion of environmental awareness, more and more heat-sensitive labels have begun to use degradable materials or add environmental protection ingredients to reduce pollution to the environment. Therefore, when choosing three heat-sensitive labels, you can also pay attention to its environmental performance and choose more environmentally friendly products.
