Description

Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to a self-moisture absorbing packaging bag. Background Art

[0002] Packaging bags refer to bags used to package various supplies, making it convenient to transport and store goods during the production and circulation process.

[0003] Nowadays, packaging bags are often sealed to achieve the moisture-proof effect. When the sealing structure fails, the packaging bag lacks a self-moisture absorption function and cannot handle the moisture inside the packaging bag, which easily causes the food and other materials inside the packaging bag to deteriorate and rot. The most common self-moisture absorption method of existing packaging bags is to add a desiccant to absorb moisture through the desiccant. However, since the desiccant is mixed with the goods and its position is not fixed, when the desiccant is located at the bottom of the packaging bag or mixed in the middle of the product, the moisture absorption effect of the desiccant will be greatly reduced. Since it is blocked by the product, it cannot achieve a good moisture absorption effect. A solution to the above problem is proposed below. Utility Model Content

[0004] The utility model aims to provide a self-moisture absorbing packaging bag, which solves the problems raised by the above-mentioned background technology.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A self-moisture absorbing packaging bag comprises a bag body, wherein the bag body comprises a wear-resistant outer layer, an antibacterial and antibacterial layer and a waterproof film, wherein the wear-resistant outer layer, the antibacterial and antibacterial layer and the waterproof film are compositely formed in sequence, a layer of the waterproof film away from the antibacterial and antibacterial layer is provided with a hygroscopic layer, a side of the hygroscopic layer away from the waterproof film is composited with an aluminum foil layer, a plurality of air holes are provided on the aluminum foil layer, each of the air holes corresponds to the internal hygroscopic layer, a storage bag is further installed on the inner wall of the packaging bag, a desiccant bag is placed inside the storage bag, the storage bag adopts a hollow structure, and a sealing component for sealing the bag body is further provided on the top of the bag body.

[0007] Preferably, the sealing assembly includes two sealing strips and two sealing grooves, the two sealing strips and the two sealing grooves are respectively installed on the two inner walls of the packaging bag body, the sealing strips and the sealing grooves are snap-fitted together, and the packaging bag body is sealed by the snap-fitting of the sealing strips and the sealing grooves, and the sealing strips and the sealing grooves both adopt a waterproof silicone structure.

[0008] Preferably, the moisture-absorbing layer is composed of a plurality of water-absorbing materials, and gaps are left between each of the water-absorbing materials for the water-absorbing materials to absorb moisture and expand. The water-absorbing materials may be highly absorbent resins.

[0009] Preferably, the sealing strip is a "convex"-shaped strip structure, and the sealing groove is a "convex"-shaped groove body.

[0010] Preferably, the top opening of the storage bag is fixed to the inner wall of the bag body using silicone-type letter buckles.

[0011] Beneficial effects: by installing a desiccant bag inside the bag body, the bag body can absorb moisture by itself, thus preventing the food or medicine placed in the bag body from spoiling and rotting. The desiccant bag is installed on the side wall of the bag body through the storage bag, so that the desiccant bag will not be mixed with the items, thus preventing the desiccant bag from failing to achieve a good moisture absorption effect. By installing a hygroscopic layer inside the bag body, the moisture entering the bag body can be adsorbed, thereby further improving the dehumidification effect of the packaging bag.

DETAILED DESCRIPTION

[0016] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0017] See Figures 1 to 3As shown, a self-moisture-absorbing packaging bag comprises a bag body 1. A sealing component 9 for sealing the bag body 1 is also provided on the top of the bag body 1. When the bag body 1 is in use, the sealing component 9 can seal the bag body 1 to prevent moisture from entering the bag body 1. The sealing component 9 comprises two sealing strips 10 and two sealing grooves 11. The two sealing strips 10 and the two sealing grooves 11 are respectively installed on the two inner side walls of the packaging bag body. The sealing strips 10 and the sealing grooves 11 are snap-fitted. The packaging bag body is sealed by the snap-fitting of the sealing strips 10 and the sealing grooves 11. Both the sealing strips 10 and the sealing grooves 11 adopt a waterproof silicone structure. The sealing strips 10 are in a "convex"-shaped strip structure, and the sealing grooves 11 are in a "convex"-shaped groove body. When sealing, the sealing effect is achieved by the concave-convex fit between the sealing strips 10 and the sealing grooves 11. Two groups of sealing strips 10 and sealing grooves 11 are provided to improve the sealing effect.

[0018] The bag body 1 includes a wear-resistant outer layer 2, an antibacterial and bacteriostatic layer 3 and a waterproof membrane 4. The wear-resistant outer layer 2, the antibacterial and bacteriostatic layer 3 and the waterproof membrane 4 are compositely formed in sequence. The design of the antibacterial and bacteriostatic layer 3 and the waterproof membrane 4 can achieve the effect of antibacterial and waterproofing.

[0019] A layer of the waterproof film 4 away from the antibacterial and antibacterial layer 3 is provided with a hygroscopic layer 5, and the side of the hygroscopic layer 5 away from the waterproof film 4 is compounded with an aluminum foil layer 6, and a plurality of air holes are opened on the aluminum foil layer 6, each of which corresponds to the internal hygroscopic layer 5. The hygroscopic layer 5 is composed of a plurality of water-absorbing materials, and gaps are left between each of the water-absorbing materials for the water-absorbing materials to absorb moisture and expand. The water-absorbing material can be a highly absorbent resin. When moisture enters the bag body 1, the hygroscopic layer 5 will absorb moisture in the air, thereby ensuring the dryness of the air and achieving the effect of self-absorption of moisture.

[0020] A storage bag 7 is also installed on the inner wall of the packaging bag, and a desiccant bag 8 is placed inside the storage bag 7. The storage bag 7 adopts a hollow structure. The desiccant bag 8 is installed inside the bag body 1 so that the bag body 1 can absorb moisture by itself to prevent the food or medicine placed in the bag body 1 from spoiling and corruption. The desiccant bag 8 is installed on the side wall of the bag body 1 through the storage bag 7, so that the desiccant bag 8 will not be mixed with the articles, preventing the desiccant bag 8 from failing to achieve a good moisture absorption effect. The top opening position of the storage bag 7 is fixed to the inner wall of the bag body 1 by a silicone-type letter buckle, and the silicone-type letter buckle is used to prevent the desiccant bag 8 from falling out of the storage bag 7 during shaking.

[0021] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.
