With the increasing demand for industrial production, more and more types of container bags are used in many industries. In the application, the container bags are not only loaded with heavy weight, but also of good quality.

The use of container bags in our country is expanding, and the export of special purpose bags such as calcium carbide and mineral products is also increasing. Therefore, the market potential of container bags is very large and the development prospect is very wide. As an export package, it is necessary to ensure the effective protection of the exported goods during loading and unloading, transportation and storage, and to deliver the goods to the destination in good condition. Therefore, the design of container bags must meet four points, that is, safety, storage, usability and tightness.

Multilayer container bag made of composite material,can be packaged like calcium carbide dangerous goods. Capacity of one ton, from the outside, in the bag, in three layers, the outer bag is composite film plastic, the inner bag is made of polyethylene film, the middle layer five to meet the special composite materials such as calcium carbide packaging.This kind of container bag has better sealing, higher strength and lower cost, compared with the traditional iron drum packaging, reducing the transportation cost more than 10%, the loss of powder is only 1/10, the economic efficiency is greatly improved.
