The embrittlement problem of large bags is actually a condition where many commodities exist. What should I do if I encounter embrittlement? Characteristic analysis of embrittlement status of plastic ton bags:
Under the geographical environment, that is, under the standard of sun exposure, the compressive strength of plastic ton bags will be reduced to 25% after one week, and will be reduced by 40% after half a month. Most of them cannot be used anymore. In other words, the storage and storage of plastic ton bags is very critical. The plastic ton bags produced by the ton bag manufacturers are made of high-pressure polyethylene, polypropylene, wire-drawing, hand-woven, stitched or pasted, and the loading volume is 25-50kg. Because of its excellent tensile strength, With high quality, low price and convenient transportation, it is commonly used for packaging of powdered raw materials such as concrete, chemical raw materials, organic fertilizers, mineral resources, grains, and edible sugar. This type of plastic ton bag packaging has gradually increased in recent years. .
In addition, after the concrete is packed in plastic ton bags, it is placed in the outdoor natural environment and exposed to the sun, which accelerates the reduction of its compressive strength. Excessive temperature (container shipping) or rain during the whole process of storage and transportation will also cause its compressive strength to decrease. Furthermore, the quality requirements for maintaining the interior items cannot be met. Therefore, the transportation, warehousing and logistics standards for plastic ton bags are very critical. Therefore, the ton bag manufacturers often stipulate in the storage and transportation standards for GB/T8946 and GB/T8947 that plastic ton bags should be stored in a cool and clean room. When transporting, they must be protected from wind and sun, and not close to the pyrogen. The period cannot exceed 18 months. In fact, plastic ton bags will become brittle in 18 months, so the effective period of plastic ton bags should be reduced, and 12 months should be appropriate.
Regarding the problem of recycled particles in plastic ton bags To ensure the packaging quality of plastic ton bags, attention should be paid to the embrittlement problem of plastic ton bags. Therefore, the national decoration industry authority has stipulated that no recycled particles and recycled materials are allowed in the raw materials for the production of plastic ton bags. The amount of filler masterbatch should be strictly limited to no more than 5%. In addition, the film temperature must be strictly controlled. Containers, why large bags and large bags will be embrittlement to prevent the problem of accelerating the embrittlement of plastic large bags due to processing technology problems. The excessive addition of recycled particles is also one of the reasons to promote the embrittlement of plastic ton bags.
