Does the long-lasting three proof thermal paper contain harmful substances to the human body?

Long term three proof thermal paper may contain harmful substances to the human body, which mainly depends on its production materials and processes.

Thermal paper is a type of paper that displays text or patterns through chemical reactions. Its main component is thermal sensitive coating, which is usually composed of colorless dyes, color developing agents, and adhesives. In long-term three proof thermal paper, some special chemicals may be added to enhance its waterproof, oil proof, alcohol proof and other properties.

Among them, bisphenol A is one of the commonly used colorants in thermal paper, which poses a certain risk to the human body. Bisphenol A is a low toxicity chemical substance that is relatively stable at room temperature. However, long-term exposure in large quantities may have adverse effects on human health, such as endocrine disorders and decreased immune function. Especially in high-temperature environments, bisphenol A may decompose into other toxic compounds and enter the human body through the skin or respiratory tract.

In addition to bisphenol A, thermal paper may also contain other harmful substances to the human body, such as benzophenone derivatives. These substances may cause allergic reactions after prolonged contact with the skin.

However, it should be pointed out that not all long-lasting three proof thermal paper contains these harmful substances. With the continuous advancement of technology and the improvement of environmental awareness, more and more manufacturers are adopting more environmentally friendly and healthy raw materials and production processes to produce thermal paper. Therefore, when choosing long-lasting three proof thermal paper, it is recommended that consumers choose legitimate channels to purchase and pay attention to the product's ingredient description and environmental certification.

To reduce the potential risks of thermal paper to human health, it is recommended to pay attention to the following points when using:

Avoid prolonged contact: Try to minimize prolonged skin contact with thermal paper, especially without protective measures.

Proper storage and use: Store thermal paper in a cool, dry, and ventilated place, avoiding high temperature, high humidity, and direct sunlight. When using, follow the correct operating procedures to avoid ingestion or inhalation of dust generated by thermal paper.

Timely cleaning: If accidentally in contact with thermal paper, the contact area should be cleaned immediately to reduce the residue of chemicals on the skin.

Pay attention to environmental certification: Choose long-lasting three proof thermal paper with environmental certification to reduce its potential risks to the environment and human health.

In summary, although long-acting thermal paper may contain harmful substances to the human body, its potential risks to human health can be minimized through proper selection and use.
