Is thermal paper safe, and is it dangerous to contact skin?

The safety of thermal paper and whether it is harmful to contact the skin need to be considered from multiple aspects.

Basic characteristics of thermal paper

Thermal paper is a kind of paper printed by thermal coating, and most of its production materials are healthy and non-toxic. However, due to the particularity of its recording method, the material of thermal paper will be added to the substance bisphenol A (BPA). Bisphenol A is a low-toxicity chemical that is stable at room temperature and has little effect on the human body.

The harm of thermal paper in contact with skin

Bisphenol A permeability:

Studies have shown that bisphenol A on thermal paper can be absorbed by the body through the skin, especially after the use of disinfectants containing skin penetration enhancers, the amount of absorption will be greatly increased. This finding suggests that prolonged or heavy exposure to thermal paper may increase the accumulation of BPA in the body.

However, it is important to note that there is no definitive conclusion on the toxicity of bisphenol A to humans. However, it is prudent to reduce exposure to it, especially pregnant women and infants should try to avoid exposure.

Allergic reactions:

The quality of thermal paper varies, and if the quality of thermal paper used is not qualified, it may cause allergic reactions, such as skin redness, itching, pain and other uncomfortable symptoms, and may also lead to skin ulceration in serious cases.

Safety under normal use:

Under normal circumstances, proper contact with thermal paper by the human body will not have adverse effects. However, if exposed to too much or for a long time, it may increase the potential risk.

Use suggestion

Control the amount of contact: minimize prolonged or large amounts of contact with thermal paper, especially when handling a large number of receipts or labels, you can wear gloves to reduce skin contact.

Pay attention to personal hygiene: After contact with thermal paper, wash your hands promptly to avoid bringing residual BPA into your mouth or touching sensitive areas.

Choose qualified products: When purchasing and using thermal paper, you should choose products of qualified quality and good reputation to reduce the risk of allergic reactions.

In summary, thermal paper is relatively safe under normal use, but prolonged or large exposure may increase the potential risk. Therefore, when using thermal paper, it is necessary to pay attention to control the amount of contact, pay attention to personal hygiene and select qualified products.
