[0002] In modern industrial production and packaging, breathable aluminum foil gaskets are an important packaging material widely used in various industries such as food, pharmaceuticals, and daily chemical products. Their unique breathability and the barrier properties of aluminum foil provide effective protection for product preservation and transportation. However, with the continuous changes in market demand and the continuous progress of technology, existing breathable aluminum foil gaskets have revealed some shortcomings in their structure. These shortcomings not only affect the performance of the gaskets but also limit their application in a wider range of fields.

[0003] Breathable aluminum foil gaskets need to withstand certain pressure and friction during the packaging process. However, existing gaskets are still insufficient in terms of strength and durability, and are prone to damage and deformation during use, affecting the service life of the gaskets and potentially threatening the safety of the packaged products. Secondly, current breathable aluminum foil gaskets have uneven structure, mainly reflected in the uneven distribution of their pores. This results in the air permeability of certain areas not being fully utilized during use, and failing to provide good and uniform protection for the items. Utility Model Content

[0004] The present invention proposes a breathable aluminum foil gasket, which solves the problems of insufficient pressure resistance and durability, as well as uneven air permeability of existing breathable aluminum foil gaskets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A breathable aluminum foil gasket includes an aluminum foil layer, a pull tab on the outer side of the aluminum foil layer, an adhesive layer at the bottom of the aluminum foil layer, a groove on the upper part of the aluminum foil layer, a reinforcing rib inside the groove, a support layer matching the groove on the upper part of the reinforcing rib, multiple sets of breathable membrane layers on the top of the support layer, a uniform air permeability mechanism inside the breathable membrane layer, and a first protective layer on the outer side of the aluminum foil layer.

[0007] Preferably, the bottom of the support layer is provided with multiple sets of support blocks, and the support layer is provided with ventilation holes between the support blocks.

[0008] Preferably, the upper part of the support layer is provided with a fixing groove that matches the breathable membrane layer, and the breathable membrane layer is provided with multiple sets of honeycomb-shaped micropores.

[0009] Preferably, the uniform air-permeable mechanism includes a first through hole, a flow guide ring, and an air vent.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 This utility model provides a technical solution: a breathable aluminum foil gasket, including an aluminum foil layer 1, which serves as the main bearing layer of the gasket. The aluminum foil layer 1 is made of high-purity aluminum material through pressing and rolling. The aluminum foil layer 1 has good electrical conductivity, thermal conductivity, and a certain tensile strength. A pull tab 2 is provided on the outer side of the aluminum foil layer 1. The main function of the pull tab 2 is to facilitate users to open and reseal the packaging, improving convenience. An adhesive layer 3 is provided at the bottom of the aluminum foil layer 1. The adhesive layer 3 uses hot melt adhesive and acrylic adhesive, which has excellent adhesion and heat resistance, ensuring the stability and reliability of the gasket in different environments and ensuring the sealing performance of the aluminum foil gasket. A groove 4 is provided inside the upper part of the aluminum foil layer 1, and a reinforcing rib 5 is provided inside the groove 4. A support layer 6 matching the groove 4 is provided above the reinforcing rib 5. Multiple sets of breathable membrane layers 8 are provided on the top of the support layer 6. A uniform air-permeable mechanism is provided inside the breathable membrane layer 8. A first protective layer 7 is provided on the outer side of the aluminum foil layer 1.

[0024] Reference Figure 2 , Figure 4 The bottom of the support layer 6 is provided with multiple sets of support blocks 9, and the inside of the support layer 6 is provided with air holes 10 between the support blocks 9. The upper part of the inside of the support layer 6 is provided with a fixing groove 11 that matches the breathable membrane layer 8, and the inside of the breathable membrane layer 8 is provided with multiple sets of honeycomb-shaped micropores 12.

[0025] Reference Figure 1 , Figure 3 The uniform air-permeable mechanism includes a first through hole 13, a guide ring plate 14, and an air vent 15. The first through hole 13 is provided in the middle of the air-permeable membrane layer 8, and the guide ring plate 14 is provided on the inner wall of the first through hole 13. The guide ring plate 14 is provided with multiple sets of air vents 15 to form a uniform air-permeable structure. The air-permeable membrane layer 8 is composed of polyethylene and polypropylene polymer materials. The air-permeable membrane layer 8 and the support layer 6 are connected to the aluminum foil layer 1 by ultrasonic welding. A second protective layer 16 is provided on the outside of the air-permeable membrane layer 8. The protective layer is made of polyethylene and polypropylene materials, which have wear-resistant and corrosion-resistant properties, effectively preventing the gasket from being contaminated and damaged by the external environment during use. A second through hole 17 matching the first through hole 13 is provided in the middle of the second protective layer 16. The reinforcing rib 5 is woven from a mixture of aramid fiber, continuous basalt fiber, glass fiber and carbon fiber, which improves the compressive strength and durability of the aluminum foil gasket.

[0026] In practical implementation, when a user needs to open the packaging, they can simply pull the pull tab 2 to tear off a portion of the aluminum foil gasket, thus opening the packaging. The pull tab 2 design also prevents the gasket from being completely torn during opening, preserving a portion of the gasket as a resealing surface. During use, air flows through the ventilation holes 10 inside the support layer 6 and then through the tiny honeycomb-like micropores 12 in the breathable membrane layer 8, effectively dissipating heat and moisture, thus providing heat dissipation and moisture protection. Simultaneously, the guide ring 14 on the inner wall of the first through hole 13 guides the filling liquid or gas smoothly through the first through hole 13 and the second through hole 17, reducing resistance and air bubble generation during filling. The multiple sets of vents 15 inside the guide ring 14 increase the breathable area of ​​the breathable membrane layer 8. Through these operations, the stability and reliability of the aluminum foil gasket's breathability are improved, bringing more convenience and benefits to people's production and lives.

[0027] In specific implementation, a breathable aluminum foil gasket is provided, and because the groove 4 is provided with reinforcing ribs 5, which are made of aramid fiber, continuous basalt fiber, glass fiber and carbon fiber mixed and woven together, in conjunction with the layered structure of the breathable membrane layer 8, as well as the protection of the first protective layer 7 and the second protective layer 16, the pressure resistance and durability of the aluminum foil gasket are further improved through the above operations.
