Is sensitive paper harmful to human body? Such problems can be seen everywhere on the network. Today we will analyze this problem from various angles.
01
Thermal paper, also known as thermal paper, is widely used in film tickets, tickets, ATM, police general paper, electronic scale paper, thermal labels and thermal cash register paper.
02
It comes from ordinary paper through surface coating. Because of this coating, thermal paper can color when it meets heat. According to different coating raw materials, it can be waterproof, oil-proof, alcohol proof, friction resistant, and the color development storage life can range from a few days to decades.
03
There is a kind of substance called bisphenol A in the coating, which belongs to low toxic chemicals, but its content is within the acceptable range of human body. At present, there are no reports of poisoning due to the use of thermal paper in the world, but the harm of long-term large-scale exposure is unknown. We suggest that pregnant women and those with traumatic skin should avoid or reduce exposure as much as possible.
04
Seeing this, many people will ask, how to judge whether the thermal paper contains bisphenol A? Xiaobian teaches you a simple method: bake on the non heat sensitive surface with a lighter. If the paper is green, it does not contain bisphenol A. if the paper is black and the color block is uneven, it contains bisphenol A
