Application of container bags in logistics industry

Container bags, also known as flexible container bags, ton bags, space bags, etc., have many English translations. Container bag is a kind of container unit equipment. The transportation of container units can be realized by using cranes or forklifts. It is applicable to the transportation of bulk powder and granular materials. Container bag is a kind of flexible transportation packaging container, which is widely used for the transportation and packaging of powder, granular and blocky items such as food, grain, chemical industry, minerals, etc.

In fact, in the field of express logistics, transit container bags are also one of the logistics container bags. However, because the specifications of delivery containers are messy, express container bags do not look as unified as logistics container bags. Implementation is not a standard for container bags.

Container bag

The container bag is made of polypropylene as the main raw material. After a small amount of stable seasoning is added, the plastic film is melted and extruded through an extruder, cut into filaments, stretched, and then heat set to high strength and low elongation. Knit and coat high speed PP yarn to make a base cloth of plastic woven fabric, and then sew it together with slings and other accessories to make a bag. In the past, the collection bags in the express field used to be container bags. At present, environmental protection cloth bags are gradually replacing container bags and vigorously promoting green packaging. Even if container bags are used in express department, they are also express packages with high recovery rate.

The "safety factor" is the ratio between the carrying capacity of the container bag and the rated design load. This mainly depends on whether the contents and main body of the container are abnormal, and whether the connection is damaged. In similar standards at home and abroad, the safety factor is generally set as 5-6 times. The five times safety factor of container bag products can be safely used for a longer time. If anti ultraviolet additives are added, the application scope of container bags will be wider and wider.

The container bag is mainly filled with blocky, granular or powdery articles. The physical density and porosity of the contents have significantly different effects on the overall effect. As for the basis for judging the performance of container bags, it is necessary to test at the position as close as possible to the product to be loaded by the customer. This is the "standard filler for testing" written in the standard. Technical standards should be used as far as possible to meet the challenges of the market economy.
