Is thermal label paper harmful to the human body?

Whether thermal label paper is harmful to the human body mainly depends on its composition, usage method, and personal health condition. The following is a detailed analysis of this issue:

Composition of Thermal Label Paper

Thermal label paper is mainly composed of a high thermal sensitivity coating, paper substrate, and adhesive layer. High heat sensitive coatings contain components such as adhesives, colorants, and colorless dyes, which undergo chemical reactions and change color under the action of heated print heads, forming graphics and text. Paper is used as the supporting material, while adhesive layer is used for adhesive fixation.

Potential harm of thermal label paper to human body

The influence of chemical substances: Thermal paper may be added with some chemicals such as bisphenol A during the production process. Bisphenol A is a low toxicity chemical with estrogenic activity that can enter the human body through various pathways. Long term exposure or ingestion may have certain effects on human health, such as increasing the risk of cancer and causing endocrine disorders. However, the amount of thermal paper that ordinary people come into contact with in their daily lives is relatively small, and the dosage of chemicals in it is also relatively low, so it generally does not cause serious toxic reactions.

Allergic reactions: For people with allergies, using thermal paper may irritate the local skin, causing allergic reactions such as itching and redness.

Respiratory irritation: Chemical substances in thermal paper may enter the body through the respiratory tract, causing irritation to the respiratory mucosa and causing discomfort such as coughing and sputum production.

Other potential hazards: Improper handling or storage of thermal paper may lead to the growth of bacteria or mold, thereby increasing the risk of infection. In addition, for sensitive populations such as infants and pregnant women, special attention should be paid to controlling the amount and duration of contact with thermal paper.

How to reduce the harm of thermal label paper to the human body

Choose legitimate products: When purchasing thermal label paper, you should choose products produced by legitimate manufacturers to ensure that the product quality meets the standards.

Reduce contact: Try to minimize direct contact with thermal paper, especially avoiding placing it in the mouth or near the nose.

Pay attention to hygiene: Wash hands promptly after contact with thermal paper to reduce the possibility of chemical residues on the skin.

Proper ventilation: During the use of thermal paper, open windows for ventilation to reduce the concentration of chemicals in the air.

In summary, thermal label paper has certain potential hazards to the human body, but as long as it is used and handled correctly, these hazards can be controlled within a safe range. For most people, the normal use of thermal label paper does not have a serious impact on their physical health. However, for sensitive populations such as infants and pregnant women, special attention should be paid to controlling the amount and duration of contact with thermal paper.
