Description

Technical Field

[0001] The utility model belongs to the technical field of paper cards, in particular to a self-adhesive paper card. Background Art

[0002] When packaging a product, it is usually necessary to paste a paper card with printed pictures and texts on the surface of the product to achieve the purpose of advertising.

[0003] At present, pressure-sensitive adhesive is mainly used for paper card bonding. Since pressure-sensitive adhesive has good bonding performance and high peeling ability, it can ensure the bonding effect and no adhesive residue will be left on the product when the paper card is subsequently torn off. However, the current pressure-sensitive adhesive does not have waterproof properties. When the paper card is accidentally stained with water, the bonding performance of the pressure-sensitive adhesive will deteriorate, causing the paper card to easily fall off the product, affecting the overall use. Utility Model Content

[0005] The technical solution adopted by the utility model is as follows: a self-adhesive paper card, comprising a paper card body with a multi-layer structure, the paper card body comprising a paper substrate and an adhesive layer and a waterproof coating formed on the inner and outer surfaces of the paper substrate respectively, the surface of the waterproof coating being coated with a wear-resistant coating;

[0006] The adhesive layer comprises an outer adhesive surface coated on the edge of the bottom surface of the paper substrate, an inner coating area is formed between the outer adhesive surface and the paper substrate, and the inner coating area is coated with the inner adhesive surface.

[0007] In a preferred embodiment, the material of the outer adhesive surface is oil-based silk screen glue, and the material of the inner adhesive surface is water-based polyurethane pressure-sensitive glue.

[0008] In a preferred embodiment, the bottom of the adhesive layer is covered with a tearable protective layer, and the protective layer is a release film with silicone oil coated on the surface.

[0009] In a preferred embodiment, one end of the protective layer protrudes to form a convex surface that protrudes out of the paper substrate, and the width of the convex surface is 2 mm to 4 mm.

[0010] In a preferred embodiment, the material of the waterproof coating is PE coating, and the thickness of the waterproof coating is 0.01 mm to 0.02 mm.

[0011] In a preferred embodiment, the wear-resistant coating is made of silicon dioxide nanomaterial.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] 1. In the utility model, a regional bonding method is adopted, and oily silk screen glue is coated on the bottom edge of the paper card. Since the oily silk screen glue has excellent high and low temperature resistance and waterproof performance, the overall bonding performance can be guaranteed even after water enters the paper surface. Moreover, it is arranged at the edge of the paper card, and it is not easy to enter the inner bonding surface when it is stained with water, thereby ensuring the overall bonding effect;

[0014] 2. In the present invention, the surface of the paper card is designed with a wear-resistant and waterproof coating, thereby increasing the overall service life in a humid and abrasive environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] Reference Figure 1-3 A self-adhesive paper card comprises a paper card body 1 of a multi-layer structure, wherein the paper card body 1 comprises a paper substrate 13 and an adhesive layer 12 and a waterproof coating 11 respectively formed on the inner and outer surfaces of the paper substrate 13, wherein the surface of the waterproof coating 11 is coated with a wear-resistant coating 10, and the adhesive layer 12 comprises an outer adhesive surface 121 coated on the bottom edge of the paper substrate 13, wherein an inner coating area is formed between the outer adhesive surface 121 and the paper substrate 13, wherein the inner coating area is coated with an inner adhesive surface 122, and the outer adhesive surface 121 is coated on the inner coating area. The material of surface 121 is oily silk screen glue, and the material of inner bonding surface 122 is water-based polyurethane pressure-sensitive glue. The overall regional bonding method is adopted, and oily silk screen glue is coated on the bottom edge of paper substrate 13. Since oily silk screen glue has excellent high and low temperature resistance and waterproof performance, the overall bonding performance can be guaranteed even after water enters the paper surface. Moreover, it is arranged at the edge of paper substrate 13, and it is not easy to enter the inner bonding surface 122 when it is stained with water, thereby ensuring the overall bonding effect.

[0021] Wherein, a decorative layer is printed on the surface of the paper card body 1 .

[0022] Furthermore, the bottom of the adhesive layer 12 is covered with a tearable protective layer 14 , and the protective layer 14 is a release film with silicone oil coated on the surface. The protective layer 14 can prevent the adhesive layer 12 from being pre-adhered and contaminated.

[0023] Furthermore, one end of the protective layer 14 protrudes to form a convex surface 141 that protrudes out of the paper substrate 13, and the width of the convex surface 141 is 2 mm to 4 mm. The above design can facilitate tearing off the protective layer 14 when the paper card is used later.

[0024] Furthermore, the material of the waterproof coating 11 is PE coating, and the thickness of the waterproof coating 11 is 0.01mm~0.02mm. A layer of PE coating is coated on the paper, and the paper and the film are completely combined and cannot be separated, which can play a good moisture-proof and waterproof effect. It has the characteristics of good toughness, high burst resistance, good waterproof and oil resistance, and can be used in products in humid environments.

[0025] Furthermore, the material of the wear-resistant coating 10 is silicon dioxide nanomaterial, which has the advantages of being waterproof, hydrophobic, oil-proof, oleophobic, anti-penetration, anti-corrosion, acid and alkali resistant, hardening, brightening, etc., making it waterproof, oil-proof and wear-resistant, so that it can be used on worn products, and can make the printed pattern on paper brighter, which can be used as an additional selling point.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
