Have different understanding of thermal paper, is thermal paper environmentally friendly? Is heat-sensitive paper harmful to human body? This kind of problem is everywhere on the network. Next, the manufacturer of SEN LIN ZHI PIN thermal paper will introduce it to you.

In the fields of film ticketing, ticketing, ATM, police paper, electronic scale, thermal label, thermal cash register paper, etc., it is also called thermal paper.

Thermal sensitive paper is made of ordinary paper sheets coated on the surface. Because of this coating, thermal sensitive paper can color when exposed to heat. According to the different coating materials, it can be waterproof, oil-proof, alcohol-proof, and friction-resistant. The storage life of color development can also vary from a few days to several decades.

The coating contains a substance called bisphenol A, which belongs to a low-toxic chemical, but its content is within the acceptable safety range of human beings. There is no poisoning phenomenon caused by the use of heat-sensitive paper in the world, but the harm caused by long-term and massive exposure is still unclear. Pregnant women and traumatic skin surfaces should try to avoid or reduce contact.

After reading so much, there must be many people who will ask, then, how can we judge that the thermosensitive paper contains bisphenol A? Next, I will teach you a simple method: bake the paper on the heat-sensitive surface with a lighter. If the paper is green, it does not contain BPA; If the paper is black and uneven in color, it contains bisphenol A.
