Paper rolls are used in many applications such as card swiping machines, point of sale (POS) machines, cash register machines, thermal printer machines, billing machines, Peggy machines, parking ticket machines, hand-held machines, weighing machines, R&D Laboratories, etc.

Thermal paper is coated with a special heat-sensitive chemical that reacts to heat by changing color, which allows the printer to create text and images without the need for ink or toner. When the paper passes over the thermal print head, the heat from the print head causes the chemical to darken, producing a high-quality print that is resistant to fading and smudging.

2-ply thermal rolls are typically sold in various widths and lengths, depending on the specific requirements of the printer or machine. They are often used in retail environments, restaurants, and other businesses that require frequent printing of receipts, orders, and other types of transactional documents.
