Top-lifting bulk bags are flexible intermediate bulk containers (FIBCs) designed for the packaging, storage and transportation of bulk materials. They are mainly made of high-strength PP woven fabric and can be rapidly lifted and moved by equipment such as forklifts and cranes via top lifting belts or lifting loops. These products are suitable for powdery, granular and lumpy materials including chemical powders, plastic pellets, mineral products, building materials, grains, feeds and fertilizers. Customizations covering bag dimensions, lifting belt structures, inlet and outlet spouts, inner liners, moisture-proof coatings and printing contents are available based on loading weight, material properties as well as filling and discharging methods. Featuring stable load-bearing capacity, convenient loading and unloading, neat stacking and high efficiency in mass transportation, top-lifting bulk bags serve as a commonly used large-capacity packaging solution for factory circulation, export packaging and container shipping.
