[0020] In one embodiment of the present invention, the base paper layer 10 is a plugging paper base paper, which is reinforced with nanocellulose and has high strength. The polyurethane layer 20 is a polymer coating, which provides viscosity as a bottom glue to adhere the ink layer 30. The mixed wear-resistant layer 400 is formed by melting polypropylene wax, mineral powder, and diluent, wherein the polypropylene wax can improve the wear resistance of the ink, overcome wiping, and improve the temperature resistance, and it also has a gravel touch; the mineral powder enhances moisture resistance, and the diluent is used for dilution and mixing to ensure adhesion after roller coating. The varnish layer 50 protects the bottom mixed wear-resistant layer 40 and facilitates hot stamping of the hot stamping layer 60.

[0021] In a preferred embodiment, the mineral powder includes one or more of calcium carbonate, dolomite, talc, silicon dioxide, silicon, mineral powder fiber or mica, which enhances wear resistance and increases the sense of touch, thereby improving anti-counterfeiting and tactile properties.

[0022] Furthermore, the weight ratio of the polypropylene wax to the mineral powder is 20:3, which is convenient for mixing into a gel.

[0023] In addition, the diluent is ethyl acetate or ethanol, which can dilute the polypropylene wax and mineral powder, reduce the excessively strong gravel touch, and improve the comfortable touch.

[0024] The ink layer 30 is set to 1-4 layers, and the ink content of a single layer is 0.1-2.0g / m2. The ink is clear and bright, and has high durability.

[0025] The thickness of the mixed wear-resistant layer 40 is 100-120 μm, the wear resistance is guaranteed, and the touch is moderate.

[0026] The present invention also discloses a manufacturing process of a gold-stamping type cigarette tipping paper, comprising: Step a. providing a fiber-reinforced base paper, and sequentially coating the base paper with a polyurethane layer, an ink layer, a mixed wear-resistant layer, and a varnish layer by a printing screen roller at a machine speed of 150-250 m / min, 60-80 lines / cm, and a depth of 40-55 μm; Step b. Maintain the machine speed at 150-250 m / min and dry with hot air at a temperature of 45-100 ° C; Step c. maintaining the machine speed at 150-250 m / min, and compounding the hot stamping layer to the surface of the varnish layer by hot pressing transfer to obtain a semi-finished product; Step d. The semi-finished product is cut into pieces and finally stored in a warehouse to obtain a gold-stamping cigarette transfer paper.

[0027] In summary, the present invention forms a mixed wear-resistant layer by melting polypropylene wax, mineral powder and diluent, thereby improving the touch of the tipping paper itself and enhancing the wear resistance of the ink layer, overcoming wiping, improving temperature resistance and avoiding the trouble of single tipping paper in the past.
