1. Thermal paper is a paper that has a special layer that is sensitive to heat on one side. This kind of paper is used by entrepreneurs/business people. Currently, almost all restaurants, supermarkets, cafes, and various other types of businesses use thermal paper to print slips or receipts for proof of their transactions with customers. With a thermal printer, printing is easier, more effective, and efficient. The surface of the thermal paper is coated with a dye and matrix mixture. Even though it looks the same as plain paper, the thermal paper has chemical properties. Thermal paper uses the chemical bisphenol-A (BPA) for coatings because of its stability and heat resistance.
The BPA allows inkless printing of receipts from cash registers. Apart from containing BPA, the thermal paper also contains BPS. The coating on the surface of the thermal paper which is coated with a mixture of dye and matrix will react with acids and change color when heated above its melting point. Keeping thermal paper close to the body for a long time can harm your body. Try to touch the back and sides of the roll paper as it usually contains less BPA. There is a special way to find out whether the shopping receipt you receive contains BPA / BPS or not. Scratch the side of your shopping receipt. If there are dark marks, it could be that the truck contains BPA. Do not store thermal paper for too long. If you want to avoid the BPA and BPS toxins that are in the thermal paper cart, start throwing the paper in the trash as soon as you don’t need it.
