The woven bag is dust-proof, moisture-proof, acid and alkali corrosion resistant, and it is light in weight and foldable, low in price, and convenient for storage. The woven bag manufacturer uses polypropylene as the main raw material, adds a small amount of stability accessories and mixes it evenly, then melts it through the extruder Plastic film is extruded, cut into filaments, and then stretched to produce high-strength and low-elongation PP strands by heat setting, and then made into a base fabric of plastic woven cloth by textile and laminating, and stitched with accessories such as slings production. It has the excellent properties of light weight, softness, high strength, acid and alkali corrosion resistance, moisture resistance and no leakage. In recent years, many companies have chosen woven bags as packaging for bulk bulk goods.

The specifications of woven bag manufacturers are not fixed, and the volume should be measured according to the specific gravity of the substance. It also depends on whether the loaded materials are sharp lumps. If so, choose a thicker base fabric when designing the woven bag, otherwise the fabric can be thinner. Some goods are placed outdoors, so the material selection should also consider adding anti-UV fabrics. Generally in the design of woven bags, the woven bag with a load of 500 kg, the base fabric is 150 g/㎡—170 g/㎡, the longitudinal tensile strength of the base fabric is 1470N/5cm—1700N/5cm, and the elongation is 20%—30 %. For woven bags with a load of more than 1000 kg, the base fabric generally chooses 170 g/㎡-210 g㎡, the longitudinal tensile strength of the base fabric is 1700N/5cm-2000N/5cm, and the elongation is 20%-30%. Due to the different tools used for loading and unloading, it is also necessary to consider whether to use a woven bag with four lifting lugs or a woven bag with two lifting lugs. The four-lug woven bag is suitable for forklift operations, and the two-lug woven bag is suitable for crane operations.
