The chemical resistance of thermal label paper varies according to the specific type and production process. In general, thermal label paper has a certain amount of chemical resistance in the conventional use environment, but not all types of thermal paper have a high degree of chemical resistance.


Influencing factor

1.Thermal coating formula: The chemical formula of the thermal coating directly affects its chemical corrosion resistance. Some high-end thermal paper products may use special chemical formulations to improve their chemical resistance and printing stability.

2.Protective layer material: The main function of the protective layer is to protect the thermal sensitive coating from the erosion of the external environment, including chemical corrosion. Therefore, the material and thickness of the protective layer are also important factors affecting the chemical corrosion resistance of thermal paper.

3.Production process: Different production processes may lead to differences in chemical resistance of thermal paper. For example, some advanced production processes may improve the chemical resistance of thermal paper by optimizing the coating distribution and improving the coating uniformity.


Special types of thermal paper

Three heat-proof paper: This kind of heat-sensitive paper usually has waterproof, oil-proof and friction-resistant characteristics, and its chemical resistance is also relatively high. It is suitable for application scenarios that need to resist certain chemical corrosion.

Long-acting thermal paper: long-acting thermal paper can maintain a long storage time after printing, and some products also have good chemical corrosion resistance to adapt to a variety of complex use environments.


Matters needing attention

Although some thermal paper products have a certain resistance to chemical corrosion, it is still necessary to avoid long-term contact with corrosive substances such as strong acids and alkali during use, so as not to cause damage to the label.

When selecting thermal labels, select the appropriate product type and manufacturer based on the requirements of the specific application scenario to ensure that the chemical corrosion resistance of the labels meet the requirements.


In summary, the chemical corrosion resistance of thermal label paper varies according to the specific type and production process. In the process of selection and use, it is necessary to evaluate and select according to actual needs.
