[0026] Thus, the accommodation groove 21 serves as a carrier for the water absorption block 22, providing a fixed position, and the water absorption block 22 can absorb moisture in the environment, and the connecting hole 24 on the isolation plate 23 allows moisture to be absorbed by the water absorption block 22 while preventing the water absorption block 22 from moving, forming an active moisture absorption system. The first sealing strip 41 and the second sealing strip 42 form a double seal, and the clamping block 43 and the clamping groove 44 are tightly engaged, ensuring the sealing reliability of the packaging bag. The Y-shaped easy-to-tear opening 6 and the semicircular easy-to-tear opening 5 provide a convenient opening method, and the special-shaped easy-to-tear opening can control the tearing direction to avoid accidental tearing. The outer packaging bag 1 is coated with a waterproof coating 11 on the surface, providing an additional waterproof protective layer. The water absorption block 22 actively absorbs moisture in the environment, reducing the humidity inside the packaging. The connecting hole 24 on the isolation plate 23 allows moisture to be absorbed while preventing the water absorption block 22 from sliding down, forming a moisture-proof system from the outside to the inside. The double sealing strips provide reliable sealing protection, and the clamping block 43 and the clamping groove 44 ensure firm sealing.

[0027] In some embodiments, referring to Figures 1 to 5 , the outer packaging bag 1 is provided with an anti-abrasion reinforcing seat 7 away from the semicircular easy-to-tear opening 5, and the anti-abrasion reinforcing seat 7 is provided with a bottom pad 8 away from the outer packaging bag 1. The outer packaging bag 1 is provided with a portable groove 9.

[0028] In this way, the anti-wear reinforcing seat 7 increases the strength and stability of the packaging bag, the bottom pad 8 can prevent the bottom of the packaging bag from being damaged due to friction or pressure, and the design of the portable groove 9 facilitates carrying and reduces the stress on the packaging bag caused by pulling. The anti-wear reinforcing seat 7 and the bottom pad 8 form a double protection, preventing the packaging bag from being damaged by external force, and the bottom pad 8 can distribute the weight to avoid the bottom of the packaging bag from being broken due to excessive load. The design of the portable groove 9 makes it easier to carry and reduces the risk of damage caused by improper handling. The anti-wear reinforcing seat 7 can effectively prevent the packaging bag from being worn during transportation and use. In this way, the anti-wear reinforcing seat 7 increases the strength and stability of the packaging bag, so that the packaging bag can better maintain its original shape when subjected to external forces, and is not easy to deform or break. This design not only improves the overall durability of the packaging bag, but also enhances its reliability in various use environments. The bottom pad 8 is designed to solve the problem of damage to the bottom of the packaging bag. Since the bottom pad 8 is usually made of wear-resistant material, it can effectively prevent the bottom of the packaging bag from being damaged due to frequent friction or excessive pressure, especially when the packaging bag needs to be placed on a rough surface or moved frequently. The effect of the bottom pad 8 is more obvious. The combination of the anti-wear reinforcing seat 7 and the bottom pad 8 forms a double protection mechanism.
