Thermal paper can indeed contain harmful substances such as bisphenol A (BPA). Thermal paper is A kind of paper printed by thermal coating, which is made by coating a normal paper base with a fine powder, which consists of colorless dyes (such as phenols or other acidic substances) and a color developer, which may contain bisphenol A.
Characteristics and effects of bisphenol A
Low toxicity: Bisphenol A is a low-toxicity chemical that is stable at room temperature and has relatively little effect on the human body.
Potential harm: However, if heated or exposed for A long time, BPA may cause damage to the human body. Bpa is considered to be an endocrine disruptor that mimics the effects of estrogen, thereby interfering with the body's endocrine system. Long-term exposure to large amounts of BPA may increase the risk of cancer, cause endocrine disorders in those exposed, and may also affect the normal development of children and induce precocious puberty.
Bisphenol A content in thermal paper
The amount of BPA in thermal paper varies from product to product, but is usually lower. However, even at low levels, long-term high exposure may have adverse effects on human health.
Matters needing attention
For sensitive groups such as infants and pregnant women, special attention should be paid to controlling the amount and time of contact with thermal paper to avoid possible physical damage.
After using items such as receipts printed on thermal paper, it is recommended to wash your hands promptly to reduce the risk of absorption of harmful substances through the skin.
If you need to save the information on the thermal paper, it is recommended to place it in a cool, dry, and dark place to avoid the accelerated release of harmful substances caused by high temperature or direct sunlight.
conclusion
In summary, thermal paper may contain harmful substances such as bisphenol A, although its content is usually low, but in the case of long-term heavy exposure may still have adverse effects on human health. Therefore, when using thermal paper, it is necessary to pay attention to control the contact time and amount, and take appropriate protective measures. At the same time, for thermal paper information that needs to be stored for a long time, attention should also be paid to its storage environment to avoid the accelerated release of harmful substances.
