FIBC is typically made from polypropylene fiber, which itself is a widely used thermoplastic resin that is polymerized from propylene monomers. It has the characteristics of light weight, corrosion resistance, high temperature resistance, impact resistance, etc., and is widely used in industrial production. Polypropylene, whose molecular structure is mainly composed of carbon and hydrogen, is an alkane polymer with a high melting point and glass transition temperature, which can withstand high temperatures up to about 130°C. In addition, polypropylene has good impact resistance, so that it is not easy to break at low temperatures. Therefore, FIBC provides a convenient and powerful support role for many industries. In agricultural production, the packaging, storage and transportation of seeds, fertilizers, pesticides, fruits and other items need to have certain protective and moisture-proof properties, and FIBC can just meet these needs to extend the shelf life of agricultural products; In the construction industry, the application of FIBC is mainly reflected in its use as an effective packaging and transportation tool. For example, FIBC can be used to load bulk materials such as cement and sand, and protect the goods from the impact of the external environment such as collision and extrusion. FIBC can also simplify the operation during the transportation and storage of goods, improve the packaging efficiency, and reduce the consumption of natural resources such as wood. Contribute to environmental protection; In addition, FIBC can effectively package and transport bulk food ingredients such as flour, sugar, salt and animal feed, which helps to improve transportation efficiency, reduce material losses and reduce packaging costs, and has a significant impact on logistics and supply chain management in the food industry.
