[0002] Thermal paper printing lamination refers to a transparent plastic film attached to the surface of thermal paper by heat pressing, which has the advantages of protection and increasing brightness. It is one of the more common processing technologies after thermal paper printing. The plastic film coated with adhesive is heated and pressed and bonded to the paper print to form a paper-plastic integrated product. Thermal paper is a processed paper. Its manufacturing principle is to apply a layer of "thermal coating" on high-quality base paper. However, when printing barcodes, QR codes, graphics, text and other image information on thermal paper, it is necessary to coat its exterior with a film to prevent natural oxidation in the later stage and friction during transportation, which will cause the printed image information to be blurred and unclear, which will affect the later identification information content.
