DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] An anti-extrusion packaging bag, as Figures 1-4As shown in the figure, it includes a bag body 1. The bag body 1 includes an outer layer 2, a first compressive layer 3, an adhesive layer 4, a second compressive layer 5, and an inner layer 6 from the outside to the inside. The cross-sections of the first compressive layer 3 and the second compressive layer 5 are both in a "V" - shaped corrugated form. There is a first air cavity 7 between the first compressive layer 3 and the outer layer 2 and the adhesive layer 4, and a second air cavity 8 between the second compressive layer 5 and the inner layer 6 and the adhesive layer 4. Specifically, the edge of the bag body 1 is reinforced by a hot-melt technology to enhance the strength and durability of the edge of the packaging bag, preventing the leakage of the contents due to edge damage during use.

[0021] Practical effect: Through multiple layers of setting, the overall compressive performance of the packaging bag is enhanced. The first compressive layer 3 and the second compressive layer 5 with a cross-section in a "V" - shaped corrugated form effectively decompose the external pressure acting on the bag body 1, and through the first air cavity 7 and the second air cavity 8, the buffering ability of the packaging bag is enhanced.

[0022] As Figures 1-4 shown in the figure, a handle end 11 is fixedly arranged at the upper end of the bag body 1. An opening is arranged at a position of the bag body 1 close to the handle end 11. An easy - tear strip 9 is arranged at the opening, and an easy - tear ring 91 is arranged on the easy - tear strip 9. The handle end 11 facilitates the movement and carrying of the bag body 1, and the easy - tear strip 9 facilitates the operator to quickly open the bag body 1.

[0023] As Figures 1-4 shown in the figure, a repeated opening and closing component is fixedly arranged inside the bag body 1 close to the easy - tear strip 9. Specifically, the repeated opening and closing component includes sealing strips 10 symmetrically arranged on both sides of the bag body 1. A card slot 101 is fixedly arranged on one side of the sealing strip 10, and a bayonet 102 that is engaged with the card slot 101 is fixedly arranged on the other side of the sealing strip 10. Through the card slot 101 and the bayonet 102 on the sealing strip 10, the bag body 1 can be repeatedly opened and closed and sealed, making the packaging bag more practical.

[0024] As Figures 1-4 shown in the figure, a moisture - absorbing chamber 13 is fixedly arranged at the bottom of the bag body 1. A number of water - permeable holes 12 are evenly distributed between the moisture - absorbing chamber 13 and the middle of the bag body 1. Activated carbon is filled in the moisture - absorbing chamber 13. Through the activated carbon filled in the moisture - absorbing chamber 13 and through the water - permeable holes 12, the environment inside the bag body 1 is kept dry and odorless, making the bag body 1 more practical.

[0025] In this embodiment, the bag body 1 is bonded by a laminating machine. The outer layer 2, the adhesive layer 4, and the inner layer 6 are all made of polypropylene materials. The polypropylene materials have stable properties and are corrosion - resistant. The outer layer 2, the adhesive layer 4, and the inner layer 6 made therefrom have relatively stable structures and are not easily damaged. The first compressive layer 3 and the second compressive layer 5 are both made of thermoplastic polyurethane elastomer materials. Thermoplastic polyurethane elastomer has excellent elasticity and compressive resistance, making the first compressive layer 3 and the second compressive layer 5 made therefrom have strong compressive ability and ensuring the structural stability of the first air cavity 7 and the second air cavity 8.
