3 Product classification
3.1 Generally, thermal paper is web paper. It can be divided into small roll thermal paper and large roll thermal paper according to specifications. For small roll thermal paper, the width is less than or equal to 300mm, the length is less than or equal to 1000m; for large roll thermal paper, the width is greater than 300mm or the length is greater than 1000m.
3.2 Thermal paper is divided into ordinary thermal paper and special thermal paper. Ordinary thermal paper refers to thermal paper with no protective coating on the surface; special thermal paper refers to a thermal paper with a protective coating on the surface and with certain specific requirements.
3.3 Thermal paper is divided into thermal fax paper, thermal cash register paper, thermal coupon paper, thermal label paper and thermal lottery paper according to its use.
