Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, specifically a double-space moisture-proof packaging bag. Background Technology

[0002] Packaging bags are an important technology in flexible packaging, and the materials used in these bags possess high toughness, tensile strength, and abrasion resistance. Generally, packaging bags have a simple tubular structure, with one end pre-sealed and the other end sealed after packaging is complete, typically using a filling process. Packaging bags are widely used in transport packaging, commercial packaging, inner packaging, and outer packaging.

[0003] Existing packaging bags are generally single-space storage bags, while multi-space packaging bags are usually made as one piece, which is inconvenient to adjust according to usage needs. They are also prone to deformation and damage when storing fragile items. In addition, they are easily affected by moisture, which affects the normal use of the packaging bags. Therefore, we have proposed a dual-space moisture-proof 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 dual-space moisture-proof packaging bag includes a main bag body and a self-sealing strip disposed at the opening of the main bag body. The main bag body has a vertically arranged support frame and a partition frame inside. The middle part of the support frame has a concave strip for the partition frame to be inserted. An air-permeable barrier film is fixed on the inner side of the partition frame.

[0007] In a preferred embodiment, the present invention can be further configured such that: a moisture-proof pad is fixed on the inner side, and the moisture-proof pad is an aluminum foil composite PE film.

[0008] In a preferred embodiment, the present invention can be further configured such that the breathable barrier membrane is an ePTFE microporous membrane with a pore size of 0.1-5μm.

[0009] In a preferred embodiment, the present invention can be further configured such that: a storage block is fixed in the middle of the breathable barrier membrane, and storage slots are provided on both sides of the storage block, with a desiccant placed inside the storage slots.

[0010] In a preferred embodiment, the present invention can be further configured such that the storage block has a honeycomb plate structure.

[0011] In a preferred embodiment, the present invention can be further configured such that: the top two sides of the separator frame are fixed with inverted V-shaped positioning strips.

[0012] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0013] 1. This utility model effectively improves the overall structural strength of the packaging bag by inserting the dividing frame into the concave strip to form a support frame perpendicular to the supporting frame. At the same time, the dividing frame, together with the breathable barrier film, separates the internal space of the packaging bag, realizing the adjustability of the usable space and making it highly practical.

[0014] 2. This utility model can achieve both internal and external moisture protection by using a moisture-proof pad and a desiccant placed inside the storage block. Furthermore, the desiccant is positioned in the middle, which not only ensures good drying effect but also prevents it from mixing with the items, making the design more reasonable.

[0020] 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.

[0021] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0022] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a dual-space moisture-proof packaging bag.

[0023] Combination Figure 1-3 As shown, the present invention provides a dual-space moisture-proof packaging bag, including a main bag body 1 and a self-sealing strip 2 disposed at the opening of the main bag body 1;

[0024] The main bag body 1 has a vertically arranged support frame 3 and a partition frame 4 inside. The support frame 3 has a concave strip 5 in the middle for the partition frame 4 to be inserted. The inner side of the partition frame 4 is fixed with a breathable barrier film 6. By inserting the partition frame 4 into the concave strip 5, a support frame perpendicular to the support frame 3 is formed, which can effectively improve the overall structural strength of the packaging bag. At the same time, the partition frame 4, together with the breathable barrier film 6, divides the space inside the packaging bag, realizing the adjustment of the usable space and making it highly practical.

[0025] Furthermore, a moisture-proof pad 7 is fixed to the inner side of the support frame 3. The moisture-proof pad 7 is an aluminum foil composite PE film. A storage block 8 is fixed in the middle of the breathable barrier film 6. Placement slots 9 are opened on both sides of the storage block 8. Desiccant is placed inside the placement slots 9. Through the moisture-proof pad 7 and the desiccant placed in the storage block 8, the internal and external moisture-proof effect can be achieved. Moreover, the desiccant is positioned in the middle, which not only has a good drying effect, but also avoids mixing with the items, making the design more reasonable.

[0026] Specifically, the breathable barrier membrane 6 is an ePTFE microporous membrane with a pore size of 0.1-5μm. The ePTFE microporous membrane has the effect of breathability and barrier, allowing water molecules to pass through but blocking the migration of solid particles, which can facilitate the rapid desiccant removal.

[0027] Furthermore, the storage block 8 has a honeycomb structure, which does not affect the dehumidification process.

[0028] Furthermore, the top two sides of the separator frame 4 are fixed with inverted V-shaped positioning strips 10, which can be positioned inside the opening of the packaging bag, ensuring not only the stability of the separator frame 4 itself, but also improving the overall structural strength of the main bag body 1.

[0029] The working principle and usage process of this utility model are as follows: First, place the support frame 3 at the bottom of the main bag body 1, then insert the divider frame 4 into the concave strip 5 as needed, then put the desiccant into the placement slot 9, and finally place the items into the spaces on both sides of the divider frame 4 and then seal it.

[0030] The terms "fixed," "installed," "connected," "set up," "open," "equipped with," "embedded," and "assembled" used in this manual to describe the position or relationship of components all refer to conventional physical connections or spatial configurations that can be understood and implemented by those skilled in the art based on the function of the relevant components, the context, and common knowledge. These relationships encompass, but are not limited to, specific forms such as welding, bonding, threaded fastening, snap-fit, interference fit, plug-in, sliding fit, hinge, integral molding, adjacent arrangement, and opening or slot accommodating. Their purpose is to clearly describe the relative positions, mating methods, and functional implementation paths between components, rather than limiting a single specific structural detail. To ensure a smooth and concise reading experience and ease of understanding, no separate explanation is provided after each term.

[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.
