Thermal paper production raw material label large roll

Thermal paper is typically produced using a base paper stock that is then coated with a thermosensitive layer on one side. When labeling or describing large rolls of thermal paper used in production, you might see terms like these: 1. Base Paper: This is the uncoated paper that forms the core of the thermal paper. It's usually made from wood pulp and can vary in weight (measured in gsm - grams per square meter) and quality. 2. Coating Layer: The thermosensitive coating is applied to one side of the base paper. This layer contains a colorless chemical mixture that changes color when heat is applied. 3. Roll Size: Large rolls of thermal paper are often described by their diameter and width. For example, a roll might be labeled as "40 inch diameter, 24 inch width." 4. GSM (Grams per Square Meter): This indicates the weight of the base paper. Common GSM values for thermal paper range from about 50gsm to 120gsm, though some specialized papers may have higher or lower GSM ratings. 5. Core Diameter: The inner diameter of the roll, typically 3 inches (76mm) or 1 inch (25mm) for thermal paper rolls. 6. Length: The length of the paper on the roll, often specified in feet or meters. 7. Finish: Some thermal papers may be labeled with finish types such as matte or glossy, though this is less common than with traditional printing papers. 8. Adhesive Backing: If the thermal paper has an adhesive backing (often used for labels), it would be mentioned, such as "thermal transfer printa
