Container bags are made of two materials: PP PE. Polyethylene (PE), abbreviated as PE, is a thermoplastic resin made by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefin. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (use temperature can reach -70 ~ -100 ℃), good chemical stability, can withstand the erosion of most acids and alkalis (not resistant to oxidizing properties) Acid), insoluble in common solvents at room temperature, low water absorption, excellent electrical insulation; but polyethylene is very sensitive to environmental stress (chemical and mechanical effects), poor heat aging resistance.
The film thickness of container bags per ton is small, the strength is improved, and the quality is good, which can reduce freight costs. In terms of storage effect, it can be stacked neatly and beautifully, and can be stacked higher, thereby reducing waste of space. In some special areas, tons of bags also have good applications, such as: geotechnical engineering, flood control materials. It is widely used in water conservancy, electric power, highway, railway, port, mine construction and military engineering construction. Plastic geotextile is one of geosynthetic materials.
The use of container bags and tons of bags can also save space in the warehouse. The standard ton bag is adjusted to handle more weight. When it is not intended to be practical, it will not occupy too much space, and it can be folded into a smaller size and stacked for storage. The materials used can be recycled, therefore. When it reaches the end of its life cycle, they can be recycled for reprocessing, which can save the use cost.
Tonnage bags are designed with a lifting ring for easy operation of mechanical lifts to move and store products and materials. Because the products have good strength, they can be stacked easily. If the goods to be handled are food or other hygienic storage environment, it is necessary to add inner bags or use related lining fabric materials to wrap the goods before using the bags.
Due to special factors, some industries need to use woven bags that are not normally used. Container bags have a stronger sunscreen capacity than ordinary woven bags, and ordinary woven bags cannot withstand long-term exposure to sunlight. It can be used in flood control. These products are indispensable materials for flood control and disaster relief, such as flood control woven bags, drought-resistant woven bags, flood control woven bags, etc. in the construction of dams, river banks, railways, and highways.
