What are the practical uses of PP woven bags？
Ⅰ.Application of PP woven bag in agricultural field?
Food storage and transportation
Loaded grain, rice, wheat, etc., insect and mildew proof.
Case: Indian farmers use PP woven bags to store rice and reduce losses in the open air.
Fertilizer and feed packaging
Chemical resistance to prevent fertilizer from clumping or moisture.
Breathable design to prevent feed mildew.
Picking and packaging of agricultural products
Cotton, coffee beans and other temporary shipment, can be cleaned and reused.
Ⅱ. Application of PP woven bag in construction and industry
Building materials transportation
Sand, cement, gypsum, etc., bearing capacity up to 12 tons.
Anti-leak lining design reduces dust pollution.
Waste disposal
Construction waste, industrial waste temporary packaging, easy to centralized transportation.
Mining and chemical raw materials
Loaded ore powder, coal particles, wear resistance and fire retardant.
Ⅲ. The comparative advantages of PP woven bag and other packaging materials
vs Sack/cloth bag: more moisture resistant, long life, low cost.
vs Paper bags: Tear resistant, reusable and suitable for wet environments.
Cost advantage: PP woven bag raw material polypropylene price is relatively low, the production process is simple, the cost is lower than paper packaging, plastic film packaging, etc., the economy is prominent in large-scale packaging demand.
Physical properties: It has high strength, good toughness, wear resistance, tear resistance, can withstand heavier items, not easy to break, more durable than paper bags. At the same time, it has good moisture resistance and can resist a certain degree of water and moisture, which is better than the sack.
Chemical stability: It has good tolerance to many chemical substances, can safely package chemical raw materials, etc., and is not easy to chemically react with the loaded substances, and the performance is better than some non-corrosion resistant packaging materials.
Recyclability: PP woven bags can be recycled, in line with the concept of environmental protection, compared with some difficult to degrade packaging materials, more friendly to the environment.
Ⅳ. Precautions in the use of PP woven bag
Load limit: Avoid breaking the sling due to excess weight (use according to nominal load).
Environmental adaptability:
Long-term outdoor need to choose anti-UV coating model to prevent aging.
High temperature environments (>80 ° C) may cause deformation.
Recycling and Environmental Protection:
After sorting and recycling, melt and then granulate, reduce environmental pollution.
Some countries have introduced a "deposit system" to encourage the return of empty bags.
Ⅴ. Conclusion
In the vast world of packaging materials,
PP woven bags with outstanding advantages, steadily occupy an important place. Its biggest highlight is the low cost, its raw material sources are wide, the production process is not complex, which makes its cost is much lower than many of the same type of packaging products, for enterprises to effectively control the packaging cost. At the same time, PP woven bags also show amazing high adaptability, which makes it like a versatile player, in many fields such as industry and agriculture, as well as daily life.
In the industrial field, whether it is fine chemical raw materials, or rough building materials, PP woven bags can be properly packaged to protect products from the external environment. In agriculture, from full grain grains to all kinds of seeds and fertilizers, it can easily be qualified for dresse-up work, providing a reliable guarantee for the storage and transportation of agricultural products. In daily life, when people move, clothes, sundries, etc. can be safely packed into PP woven bags, which is convenient and practical.
Not only that, enterprises can also optimize and upgrade the functions of PP woven bags according to specific needs. For example, in some static-sensitive industries, add anti-static functions; In the field of food packaging, PP woven bags that meet food-grade safety standards have been developed to meet the strict requirements of food packaging. In the pursuit of functionality at the same time, the company has not ignored the responsibility of environmental protection, through continuous improvement of production technology, so that PP woven bags on the basis of ensuring practicality and economy, more in line with the concept of sustainable development, to meet the current packaging needs at the same time, to contribute to the future ecological environment.
