Big bag is a commonly used packaging woven bag, which is widely used. We know that after one use, the strength of the big bag will decrease and oxidation will occur.
Big bags are made of polypropylene by drawing, weaving, sewing or pasting, and the loading weight is generally 200kg-3T. In the natural environment, that is, under the condition of direct sunlight, the strength of plastic container bags will be reduced to 25% after one week, and will be reduced by 40% after two weeks, which is basically unsafe. Therefore, the storage and storage of large bags is very critical.
Big bags should be stored in a cool and clean room. During transportation, avoid sunlight and rain, and should not be near heat sources. The deposit period shall not exceed 18 months. In fact, the plastic tonnage maybe 18 months old, so the validity period of the tonnage should be shortened, try to be within 12 months.
Big bags should be stored out of direct sunlight. The packaging material of the ton bag is woven with ordinary woven cloth, which is often referred to as 10X10 low denier flat wire; in the production of ton bags, it is mainly divided into: (wrapping cloth), upper and lower bottom cloth, feeding and discharging outlet tube cloth three parts.
In addition, when the big bag is transported, for the convenience of stacking, no matter what the shape is, the upper and lower bottoms are sewn to hide the inlet and outlet. However, it should be noted that the lower base fabric is also woven with 14X14 high-denier flat wire due to its large force, and the upper base fabric can be woven with ordinary woven bags. However, because the upper and lower base fabrics are of the same size, it is convenient for production and reduces the process flow. Most manufacturers use 14X14 high denier flat wire to weave the upper and lower bottom. The use of ton bags is different from other products. It can be recycled, and coupled with its convenience in transportation, more and more industries will choose ton bags for packaging.
