AI Technical Summary
The existing velvet-feel aluminum foil paper has poor anti-blocking properties of the velvet resin, which makes the aluminum foil paper sticky and the velvet effect is not obvious.
A velvety layer is set on one side of the varnish layer of the aluminum foil paper as a connecting layer between the velvety layer and the ink layer. It absorbs some of the velvety resin, improves the anti-blocking performance, and forms patterns and velvety effects through stencil printing and full-page printing techniques.
It improves the anti-blocking properties of aluminum foil, enhances the velvety printing effect and visual appeal, reduces aluminum foil sticking, and maintains gloss and printing effect.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary materials for tobacco products, and in particular to an anti-adhesion aluminum foil paper. Background Technology
[0002] Cigarette inner lining paper refers to paper made by bonding aluminum foil backing paper to aluminum foil. It is soft and easily deformed, like paper, and does not spring back after deformation; hence the common name "aluminum foil paper." In existing technology, velvety aluminum foil paper is usually printed with velvety varnish to give it a soft, velvety feel. However, the velvety resin has poor anti-blocking properties because aluminum foil has strong barrier properties, preventing the resin from penetrating and being absorbed by the backing paper. High resin content can cause the aluminum foil to become sticky; low resin content results in no noticeable velvety effect. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-adhesion aluminum foil paper.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: an anti-adhesion aluminum foil paper, comprising:
[0005] Aluminum foil layer;
[0006] One side of the aluminum foil layer is connected to the backing paper layer via an adhesive layer;
[0007] An ink layer is provided on the other side of the paper liner layer;
[0008] A varnish layer is provided on the other side of the ink layer;
[0009] A velvety layer is provided on the other side of the varnish layer.
[0010] As a further description of the above technical solution: the backing paper layer is double-sided glossy aluminum foil backing paper.
[0011] As a further description of the above technical solution: the thickness of the liner paper layer is 20-80μm.
[0012] As a further description of the above technical solution: the thickness of the ink layer is 1-3μm.
[0013] As a further description of the above technical solution: the thickness of the velvety layer is 1-3 μm.
[0014] As a further description of the above technical solution: the amount of adhesive applied to the adhesive layer is 0.5-1.0g.
[0015] As a further description of the above technical solution: the aluminum foil layer thickness is 55-65μm.
[0016] As a further description of the above technical solution: the thickness of the varnish layer is 1-10μm, and the gloss is 0-5.
[0017] As a further description of the above technical solution: the ink layer is stencil printed, forming a pattern on the backing paper layer.
[0018] As a further description of the above technical solution: the velvety layer is printed on the entire surface and is evenly distributed on the varnish layer.
[0019] The above technical solution has the following advantages or beneficial effects:
[0020] By setting a velvet layer on one side of the varnish layer as a connecting layer between the velvet layer and the ink layer, the printing effect of the ink in the velvet layer can be improved, and at the same time, some of the velvet resin can be absorbed to improve the anti-blocking performance of the aluminum foil paper.

[0023] 1. Aluminum foil layer; 2. Adhesive layer; 3. Backing paper layer; 4. Ink layer; 5. Varnish layer; 6. Velvet layer. Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figure 1 An embodiment of this utility model provides an anti-adhesion aluminum foil paper, comprising: an aluminum foil layer 1; one side of the aluminum foil layer 1 is connected to a backing paper layer 3 via an adhesive layer 2; an ink layer 4 is disposed on the other side of the backing paper layer 3; a varnish layer 5 is disposed on the other side of the ink layer 4; and a velvet layer 6 is disposed on the other side of the varnish layer 5.
[0026] In this embodiment, a velvet layer is provided on one side of the varnish layer as a connecting layer between the velvet layer and the ink layer; this can improve the printing effect of the ink in the velvet layer, and at the same time, it can absorb some of the velvet resin, thereby improving the anti-blocking performance of the aluminum foil paper.
[0027] The backing paper layer 3 is a double-sided glossy aluminum foil backing paper. The thickness of the backing paper layer 3 is 20-80μm.
[0028] In this embodiment, the backing paper layer 3 has good flatness and paper fibers on both sides, which can improve the surface flatness and printing effect, and eliminate the fiber burr problem of traditional single-sided glossy paper. When the finished aluminum foil paper is stored, it can also reduce the adhesion between the paper fibers of the backing paper layer 3 and the printed surface of the aluminum foil layer 1 caused by the stickiness of the velvety ink.
[0029] The thickness of ink layer 4 is 1-3 μm. Ink layer 4 is stencil printed, forming a pattern on the backing paper layer 3.
[0030] In this embodiment, the ink layer 4 is disposed on one side of the backing paper layer 3, filling the fine pores of the backing paper layer 3. The ink is a water-based ink, preferably a black water-based varnish, and a stencil pattern is printed on the backing paper layer 3 by gravure or flexographic printing, with the smooth surface of the backing paper layer 3 exposed in the non-printed areas.
[0031] The amount of adhesive applied to the adhesive layer 2 is 0.5-1.0g.
[0032] In this embodiment, the adhesive layer 2 is thin and uniform to prevent bubbles or wrinkles and to avoid penetrating to the surface of the aluminum foil layer 1 and affecting the gloss. The adhesive layer 2 is a water-based adhesive to ensure that the aluminum foil layer 1 and the backing paper layer 3 are tightly bonded and to avoid delamination.
[0033] The thickness of aluminum foil layer 1 is 55-65μm.
[0034] In this embodiment, the aluminum foil layer 1 serves as a barrier layer, possessing good shape retention, moisture resistance, and oxidation resistance.
[0035] The thickness of the varnish layer 5 is 1-10μm, and the gloss level is 0-5.
[0036] In this embodiment, the varnish layer 5 is a matte water-based ink with a gloss similar to that of the velvety ink, serving as a connecting layer between the velvety layer and the ink layer. It can improve the printing effect of the velvety ink, while also absorbing some of the velvety resin to improve the anti-blocking properties of the aluminum foil paper, filling the fine pores of the ink layer 4, and enhancing its abrasion resistance.
[0037] The varnish layer 5 can also effectively reduce the strong reflective properties of the aluminum foil layer 1, avoiding visual glare.
[0038] The velvet layer 6 is printed on the entire surface and is evenly distributed on the varnish layer 5. The thickness of the velvet layer 6 is 1-3μm.
[0039] In this embodiment, the ink of the velvet layer 6 is a fully matte ink, which enhances the appearance of the aluminum foil.
[0040] The combination of ink layer 4 and velvet layer 6, along with velvet matte ink, creates a distinct three-dimensional effect in the printing, resulting in a superior visual appeal.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
