[0013] This invention increases the contact area with the inner bag by setting up a symmetrical support frame and a wave-shaped sidewall design. The multi-point support is formed by heat fusion fixing of the crests and troughs, which effectively disperses the local stress caused by powdery or sharp objects, preventing the bag from sagging, deforming, and tearing. The hinged bottom plate can adaptively adjust its angle according to the shape of the contents of the inner bag. Combined with the elastic constraint of the elastic rope, it allows for flexible deformation while ensuring the rigidity of the support, thus improving stacking stability. The fixing frame penetrates the outer bag interlayer and is connected to a magnetic strip to realize the opening sealing and repeated opening and closing functions, reducing the risk of moisture to the contents. The magnetic strip is embedded in the interlayer to avoid damage from external forces and extend its service life. The polyester fiber buffer layer between the inner and outer bags reduces the impact of collisions during transportation and further prevents the bag from breaking. Attached Figure Description
