Description

Technical Field

[0001] The utility model relates to the technical field of thermal paper, in particular to an anti-static heat-insulating thermal paper. Background Art

[0002] Thermal paper, also known as thermal fax paper, thermal recording paper, or thermal copy paper, is a processed paper manufactured by coating high-quality base paper with a layer of "thermosensitive coating," also known as a thermochromic layer. When heated, the colorless dye in the thermal paper reacts with a developer to produce color. This allows images and text to appear when the thermal paper is used to receive and print signals on a fax machine or directly on a thermal printer.

[0003] The existing Chinese patent with announcement number CN201893071U discloses a multi-layer thermal paper self-adhesive label, comprising at least one layer of label substrate and at least two layers of label surface material respectively adhered to two opposite surfaces of the label substrate, which can print multiple labels at a time and improve printing efficiency. However, the above-mentioned existing technical solutions have the following defects: in dry climates, if the thermal paper frequently contacts and separates from foreign objects, static electricity will be generated. The energy released by static electricity may affect the quality of printing. At the same time, static electricity will cause the product to easily absorb dust and impurities, affecting the use of the product. Therefore, an anti-static heat-insulating thermal paper is proposed. Utility Model Content
