Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, specifically a cigar packaging bag. Background Technology

[0002] A cigar is a tobacco product made by rolling dried and fermented tobacco.

[0003] Existing cigar packaging mostly uses ordinary sealed bags, which cannot provide a stable humidity environment, easily leading to cigars drying out or becoming moldy. Although some products have tried to add humidifying components, there are problems such as humidifying liquid leakage and uneven humidity distribution. Therefore, we have proposed a new type of cigar packaging bag. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A cigar packaging bag includes: a first sheet and a second sheet, both the first sheet and the second sheet being composed of an outer OPP film and an inner first PE film; a second PE film is disposed between the first sheet and the second sheet, the edge of the second PE film being heat-sealed to the edge of the second sheet to form a closed first receiving space, the first receiving space being filled with a humectant; a second receiving space for placing cigars is formed between the second PE film and the first sheet.

[0007] The present invention can be further configured such that the thickness of the OPP film is 15-30μm, and the thickness of the first PE film and the second PE film are both 20-50μm.

[0008] The present invention can be further configured such that the heat-sealing width between the second PE film and the second sheet is 3-8mm and the heat-sealing temperature is 120-150℃.

[0009] This invention can be further configured such that the second PE membrane has breathable micropores for small molecule exchange.

[0010] The present invention can be further configured such that: the outer surface of the OPP film of the first sheet is coated with an anti-ultraviolet coating.

[0011] This utility model can be further configured such that: the openings of the first sheet and the second sheet are provided with a sealing structure.

[0012] This utility model can be further configured such that the sealing structure is a sealing strip.

[0013] This invention can be further configured such that the sealing structure is an adhesive sheet.

[0014] This utility model can be further configured such that the sealing structure is a PP zipper.

[0015] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0016] 1. This utility model uses a double-layer PE film composed of a first PE film and a second PE film to isolate the moisturizing liquid from the cigar, which can effectively prevent direct contact from causing mold growth.

[0017] 2. This invention can effectively extend the shelf life of cigars through breathable micropores and UV-resistant coating. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of a cigar packaging bag provided by this utility model.

[0024] Combination Figure 1 As shown, the present invention provides a cigar packaging bag, comprising: a first sheet 1 and a second sheet 2, both the first sheet 1 and the second sheet 2 being composited from an outer OPP film 11 and an inner first PE film 12; a second PE film 3 is disposed between the first sheet 1 and the second sheet 2, the edge of the second PE film 3 being heat-sealed to the edge of the second sheet 2 to form a closed first accommodating space 4, the first accommodating space 4 being filled with a moisturizing liquid 5; a second accommodating space 6 for placing cigars is formed between the second PE film 3 and the first sheet 1. The second PE film 3 is provided with breathable micropores for small molecule exchange.

[0025] Specifically, the second PE film 3 completely isolates the humectant 5 from the cigar, preventing the liquid from directly contacting the cigar and reducing the risk of mold. At the same time, the breathable micropores of the PE film allow the humectant to slowly release moisture into the second container space 6, ensuring uniform and stable humidity and achieving a moisturizing effect.

[0026] Furthermore, the OPP film 11 has a thickness of 15-30 μm, and the first PE film 12 and the second PE film 3 both have a thickness of 20-50 μm. The OPP film thickness range ensures the outer layer's abrasion resistance and barrier properties, while avoiding excessive thickness that could lead to increased brittleness. At the same time, the PE film thickness provides sufficient flexibility to facilitate folding and sealing of the packaging bag.

[0027] On the other hand, the heat-sealing width between the second PE film 3 and the second sheet 2 is 3-8mm, and the heat-sealing temperature is 120-150℃. The heat-sealing width ensures sufficient bonding area to avoid delamination due to uneven pressure. At the same time, this temperature range prevents insufficient heat melting or excessive carbonization of the PE film.

[0028] Furthermore, the moisturizing liquid 5 is a mixed solution of propylene glycol and deionized water in a ratio of 1:2 to 1:4. Propylene glycol has both hygroscopic and antibacterial properties; when mixed with deionized water, it can maintain humidity and inhibit the growth of microorganisms. Commercially available moisturizing liquids can also be used. During production, an injection port can be reserved at the end of the first accommodating space 4 furthest from the bag opening. After injecting the moisturizing liquid into the first accommodating space 4, the bottoms of the first sheet 1 and the second sheet 2 are heat-sealed.

[0029] Furthermore, the outer surface of the OPP film 11 of the first sheet 1 is coated with an anti-ultraviolet coating 7 to block ultraviolet radiation, prevent the photolysis and oxidation of oil and aroma components in cigars, extend shelf life, and at the same time, the coating can simultaneously improve the scratch resistance of the OPP film and keep the packaging bag clean.

[0030] It should be noted that the openings of the first sheet 1 and the second sheet 2 are provided with a sealing structure. The sealing structure is one of a sealing strip, an adhesive sheet, and a PP zipper, which allows the packaging bag to be reused and is applicable to more scenarios and needs.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
