Definition: A container bag, also known as a flexible container bag, ton bag, space bag, etc., is a flexible and foldable packaging container, usually made of high-strength synthetic fiber materials such as polypropylene or polyethylene.
Usage: Widely used in the packaging and transportation of various bulk goods such as chemical, building materials, grain, mineral products, etc., it can effectively improve loading and unloading efficiency, reduce transportation costs, and protect the quality of goods.
structure and characteristics
Structure: Generally composed of bag body, sling, feeding port, discharging port, and other parts. The bag body is the main part for storing goods; The sling is used for lifting and transporting container bags; The inlet and outlet facilitate the loading and unloading of goods.
characteristic
Large capacity: It can usually accommodate 1-3 tons of goods, greatly improving transportation efficiency.
Good flexibility: Foldable for storage, occupying small space, easy to transport and store.
High strength: able to withstand significant weight and pressure, ensuring the safety of goods during transportation.
Good sealing: can effectively prevent cargo leakage, moisture, contamination, etc.
classification
Classified by shape: there are circular container bags, square container bags, U-shaped container bags, etc. Circular container bags are more common, while square container bags are more convenient for stacking and storage. U-shaped container bags are used in some special occasions, such as when side unloading is required.
Classified by purpose: It can be divided into ordinary container bags, anti-static container bags, anti radiation container bags, food grade container bags, etc. Anti static container bags are used to package goods that are sensitive to static electricity, such as flammable and explosive materials; Food grade container bags comply with food hygiene standards and are used for packaging food related goods.
Classified by unloading method: there are top unloading container bags, bottom unloading container bags, and side unloading container bags.
Production process
The production process of container bags mainly includes raw material selection, drawing, weaving, cutting, sewing, printing and other links. Firstly, raw materials such as polypropylene or polyethylene are extruded into silk through an extruder, and then the silk is woven into fabric. Then, according to design requirements, cutting and sewing are carried out to form components such as bags and straps. Finally, printing and other post-processing processes are carried out, such as adding anti-static agents, anti UV agents, etc.
use and maintenance
Precautions for use: When using container bags, it is important to choose the appropriate model and specifications to ensure that they can withstand the weight of the goods; When lifting, special lifting equipment should be used to avoid contact between the sling and sharp objects, and to prevent the sling from breaking; During loading, unloading, and transportation, it is necessary to avoid collisions, friction, and compression of the container bags to prevent damage to the bag body.
Maintenance: After use, the container bag should be cleaned in a timely manner to remove any remaining goods and impurities inside the bag; If the container bag is damaged, it should be repaired or replaced in a timely manner; When storing, the container bag should be placed in a dry and ventilated place, avoiding direct sunlight and rain to extend its service life.
