Description

Technical Field

[0001] The utility model relates to the field of cigarette packaging materials, in particular to moisture-proof cigarette packaging paper. Background Art

[0002] The materials of cigarette boxes mainly include paper, aluminum and tinplate, among which paper cigarette boxes are the most common type. This material is light and low in cost, suitable for mass production. Since cigarettes need to be stored in a dry environment, the moisture resistance of cigarette box packaging paper is very important. For example, a moisture-proof cigarette packaging paper disclosed on the China Patent Network (public announcement number CN209498548U) shows that this type of cigarette packaging paper is provided with a moisture-proof adsorption paper layer, and utilizes the adsorption cotton thread on its mesh to absorb moisture in the cigarettes, thereby achieving the effect of moisture-proof protection. For example, a multi-layer environmentally friendly cigarette box packaging paper disclosed on the China Patent Network (public announcement number CN205633581U) shows that this type of packaging paper achieves its moisture-proof adsorption ability by arranging deodorizing particles with adsorption capacity inside it.

[0003] However, the aforementioned patented and currently marketed cigarette packaging papers still have some shortcomings: the former utilizes absorbent cotton threads for moisture-proof absorption, resulting in a relatively low independent moisture-proof absorption capacity; while the latter utilizes granular absorbent materials, which are easily detached from the packaging paper during bending or subsequent use by the user, resulting in poor moisture-proof stability. Therefore, those skilled in the art have provided moisture-proof cigarette packaging paper to address the issues raised in the aforementioned background art. Utility Model Content

[0004] In view of the deficiencies of the prior art, the present invention provides moisture-proof cigarette packaging paper, which solves the problem of relatively low moisture-proof ability of the existing cigarette box packaging paper mentioned in the background art.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: Moisture-proof cigarette packaging paper, including cigarette wrapping paper;

[0006] The cigarette packing paper comprises a pattern-printed paper body, the outer surface of the pattern-printed paper body is provided with a waterproof film, and the inner surface of the pattern-printed paper body is provided with a moisture-proof inner lining paper;

[0007] The moisture-proof inner lining paper comprises a first moisture-proof layer, a second moisture-proof layer and a needle-punched inner lining layer which are sequentially connected.

[0008] As a further technical solution of the present invention: the first moisture-proof layer is made of high-density polyurethane soft foam material, the second moisture-proof layer is made of activated carbon fiber cloth material, and the needle-punched lining layer is made of cellophane material.

[0009] As a further technical solution of the present invention: the paper surface of the needle-punched liner layer is provided with needle-punched holes arranged in an array.

[0010] As a further technical solution of the present invention: a packaging coating is printed on the outside of the pattern-printed paper body, and the pattern-printed paper body is connected to the waterproof film by hot pressing.

[0011] As a further technical solution of the present invention: the waterproof membrane is made of BOPP polypropylene film material.

[0012] The utility model provides a moisture-proof cigarette packaging paper, which has the following beneficial effects compared with the prior art:

[0013] The cigarette packaging paper of the present invention has a moisture-proof inner padding paper, which uses its needle-punched inner lining layer to conduct with the air in the cigarette box, and then uses a double adsorption combination of a second moisture-proof layer of activated carbon fiber cloth material and a first moisture-proof layer of high-density polyurethane soft foam material to play a double moisture-proof adsorption role for the air inside the cigarette box, providing efficient moisture-proof protection for the cigarettes inside the cigarette box. The first moisture-proof layer of polyurethane soft foam material and the second moisture-proof layer of activated carbon fiber cloth material have good flexible bending properties. When bent into a cigarette box or subsequently carried, they can still have stable structural properties and play a long-lasting moisture-proof adsorption role. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In the figure: 1, cigarette wrapping paper; 11, pattern-printed paper; 12, waterproof membrane; 13, moisture-proof inner lining paper; 131, first moisture-proof layer; 132, second moisture-proof layer; 133, needle-punched inner lining layer. DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-3The utility model provides a technical solution for moisture-proof cigarette packaging paper: the moisture-proof cigarette packaging paper includes a cigarette paper 1, the cigarette paper 1 includes a pattern-printed paper body 11, a waterproof film 12 is provided on the outside of the pattern-printed paper body 11, a packaging coating is printed on the outside of the pattern-printed paper body 11, and the pattern-printed paper body 11 and the waterproof film 12 are connected by hot pressing. The waterproof film 12 is made of BOPP polypropylene film material. After the packaging pattern is printed on the pattern-printed paper body 11, the waterproof film 12 is hot-pressed and bonded to the pattern-printed paper body 11 by hot pressing. While isolating and protecting the printed pattern, the physical stability, mechanical strength and air tightness of the BOPP polypropylene film material waterproof film 12 can be utilized to provide good waterproof protection for the cigarette box packaging paper and enhance the tensile strength of the paper.

[0020] The inner surface of the pattern-printed paper body 11 is provided with a moisture-proof inner lining paper 13. The moisture-proof inner lining paper 13 includes a first moisture-proof layer 131, a second moisture-proof layer 132, and a needle-punched lining layer 133 which are arranged in sequence. The first moisture-proof layer 131 is made of high-density polyurethane soft foam material, and the second moisture-proof layer 132 is made of activated carbon fiber cloth material. The first moisture-proof layer 131 of high-density polyurethane soft foam material and the second moisture-proof layer 132 of activated carbon fiber cloth material both have good moisture absorption and drying capabilities, and can efficiently absorb moisture that may be generated inside the cigarette box, and both have good flexible bending properties. When the packaging paper is cut and bent into a cigarette box, it can still maintain stable structural characteristics after folding, has stronger anti-interference ability against the external environment, and can always maintain its stable moisture-proof adsorption performance.

[0021] The needle-punched lining layer 133 is made of cellophane material, and the paper surface of the needle-punched lining layer 133 is arranged in an array with needle-punched holes. By setting the needle-punched lining layer 133 as cellophane material, it has good profile bending performance, and by providing needle-punched holes on the needle-punched lining layer 133, it is beneficial to the circulation and diffusion of air inside the cigarette box, so that the first moisture-proof layer 131 and the second moisture-proof layer 132 can perform efficient moisture-proof adsorption work.

[0022] The working principle of the utility model is: when the cigarette packaging paper is processed into a cigarette box, the moisture-proof inner lining paper 13 is arranged inside the cigarette box in a built-in processing manner (as shown in the attached manual). Figure 3 As shown, when cigarettes are stored in the cigarette box, the microporous air permeability of the needle-punched inner lining layer 133 in the moisture-proof inner lining paper 13, as well as the double lining of the first moisture-proof layer 131 of high-density polyurethane soft foam material and the second moisture-proof layer 132 of activated carbon fiber cloth material, both of which have good moisture absorption and drying capabilities, can effectively absorb moisture that may be generated inside the cigarette box;

[0023] When the wrapping paper is cut and bent into a cigarette box, since the first moisture-proof layer 131 and the second moisture-proof layer 132 both have good flexible bending properties, they can still maintain stable structural characteristics after the cigarette box is folded, and have stronger resistance to interference from the external environment, and always maintain its stable moisture-proof adsorption performance.

[0024] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
