[0024] Embodiment 2:

[0025] Based on the first embodiment, Figure 1 and Figure 4As shown, a pressure-bearing layer 13 is provided inside the high-pressure bag body 1, an inner layer 14 is provided on the inner surface of the high-pressure bag body 1, a plurality of anti-slip grooves 5 are provided on the surface of the tear paper 4, the surface of the polypropylene layer 11 and the surface of the adhesive layer 12 are bonded to each other, and an adhesive layer 6 is bonded to one side of another compression strip 2. The utility model provides a high-pressure bag with high tensile strength. The polypropylene layer 11, the adhesive layer 12, the pressure-bearing layer 13 and the inner layer 14 are provided. The polypropylene layer 11 has high strength and good air permeability and waterproofness. The adhesive layer 12 is made of styrene-butadiene rubber and serves as an adhesive between the inner bag and the outer layer, thereby improving the sealing and durability of the high-pressure bag and enhancing the tensile strength of the high-pressure bag.

[0026] Working principle: High-pressure bag is a packaging bag with specific functions and characteristics. It is mainly used for packaging powdery and granular items. It is a bag that can withstand higher pressure and is usually made of polypropylene. The size and thickness of the bag can be customized according to specific needs to meet the packaging needs of different items. High-pressure bag can withstand higher pressure, which helps to reduce the crushing of granular items and the damage of packaging bags during transportation. High-pressure bag can store items, but the opening of existing high-pressure bag is not easy to seal. Incomplete sealing will cause the liquid inside the bag to leak out, thereby affecting the quality and shelf life of the items in the bag. Leakage may cause the items to become damp, deteriorate, or even contaminated. If the opening is not firm, it is easy to be torn and damaged during transportation, shortening the service life of the high-pressure bag. The tensile strength and corrosion resistance of the high-pressure bag need to be strengthened. Therefore, after the high-pressure bag body 1 stores the items, the anti-slip pattern 5 increases the friction between the finger and the tear paper 4, so that the tear paper 4 can be manipulated faster, and the tear paper 4 is torn off. The tear paper 4 is connected to the isolation film on the surface of the adhesive layer 3. The isolation film on the surface of the adhesive layer 3 can be torn off. After the isolation film is torn off, the sticky part of the adhesive layer 3 will be exposed. Then, the two pressing strips 2 are folded in half to make the sticky part of the adhesive layer 3 adhere to the surface of the adhesive layer 6. The two pressing strips 2 can achieve sealing, thereby sealing the opening of the high-pressure bag body 1. The four reinforcement strips 8 are relatively moved to make the four first magnet strips 9 and the four second magnet strips 10 magnetically connected, so that the two restraining strips 7 can continue to be closed, thereby enhancing the two pressing strips 2 on the high-pressure bag The stability of the airtight opening of the main body 1 avoids air leakage of the high-pressure bag body 1 and improves the quality of item storage. The polypropylene layer 11 has high strength and good air permeability and waterproofness. The adhesive layer 12 is made of styrene-butadiene rubber and serves as an adhesive between the inner bag and the outer layer, which improves the sealing and durability of the high-pressure bag and also enhances the tensile strength of the high-pressure bag. The pressure-bearing layer 13 is made of a fiber-reinforced layer material and can strengthen the strength of the high-pressure bag body 1 by weaving. The inner layer 14 is made of polyurethane and can directly contact the liquid, so it has excellent corrosion resistance.
