After the cement is packed in woven bags and exposed to direct light in the open air, the intensity will drop sharply. During storage and transportation, excessive temperature or exposure to rain can reduce the strength and may not meet the quality requirements to protect the contents.
Warehouse conditions for transportation of woven bags are very important. Woven bags should be stored in a cool and clean room. During transportation, sunlight and rain should be avoided, and they should not be close to heat sources. The storage time should not exceed 18 months. In fact, the woven bag will age in 18 months, so the validity period of the woven bag packaging should be shortened by 12 months.
Regarding the issue of recycled materials for woven bags, in order to ensure the quality of woven bags, we must attach great importance to the aging of plastic woven bags. For this reason, the competent department of the building materials industry requires that the raw materials for bag making must strictly limit the mixing amount of recycled materials, return materials, and filling materials to be less than 5%, and at the same time, strictly control the peritoneal temperature to prevent accelerated aging caused by process problems. Excessive amount of recycled materials Addition is also one of the reasons for the aging of plastic bags.
