Composite hoses are a very special type of packaging container and hold an important position in the packaging field. A composite hose is a "cylindrical packaging container made of flexible materials, sealed after folding, forming a tube with a nozzle at one end; when squeezed, the contents are dispensed through the nozzle."

Types of Composite Hoses:

1. Multi-purpose oil-resistant composite hose: widely used for transporting liquid and gaseous fuels such as gasoline, diesel, kerosene, crude oil, and other hydrocarbon products.

2. Multi-purpose chemical transport hose: widely used for transporting corrosive chemical liquids and gases, with chemical-resistant properties.

3. Automotive hose: specially designed for use with tank trucks. It is soft, lightweight, suitable for frequent bending and movement, designed for long service life, and is a general-purpose tank truck hose.

4. Dock and ship loading/unloading hose: specifically for dock and ship use, with reinforced structure, heavy-duty design, chemical-resistant properties, and able to bend frequently without cracking.

5. Paint and coating transport hose: specially designed for paint and coating products, with solvent resistance, wear resistance, and anti-oxidation performance.

6. Low-temperature hose: used in low-temperature environments or for transporting low-temperature products such as ethylene, LPG, LNG, propane, dry ice, etc.

7. High-temperature hose: used for transporting high-temperature products such as hot water and hot oil.
