The bottom features a large flip opening structure fixed by dual fasteners of velcro and binding ties, ensuring tight sealing and easy opening.
After opening, the extra-large unobstructed outlet enables complete one-time discharge with no dead corners. Wall-adhered, residual or caked materials can be manually cleared rapidly for zero residue and zero waste.
When closed, it stays tightly sealed and load-bearing stable without interfering with regular transport and stacking.
The structure is tear-resistant and durable with long service life; it won’t deform or loosen after repeated opening and closing, specially designed to resolve the pain point of difficult discharging and material residue.
