thermal paper raw material

Thermal paper is a type of paper that is coated with a chemical that changes color when exposed to heat. It is commonly used in thermal printers, which use heat to create images or text on the paper. The thermal paper is typically used for printing receipts, tickets, and other documents that require a temporary record. It is also used in fax machines, cash registers, and credit card terminals. The color change on the thermal paper is caused by a reaction between the heat and the chemical coating, which creates a visible image. The paper is sensitive to light, heat, and friction, and it can fade over time, so it is not suitable for long-term storage of important documents.
