Inflatable bag material: the outer bag of the inflatable bag is composed of high-strength kraft paper, PP woven bag and PE film. Although only one layer of kraft paper is used for the outer bag of the inflatable bag, due to the use of special technology and high-quality raw materials, its strength is equivalent to that of foreign products made of 2-3 layers of kraft paper. Inflatable bag is the only manufacturer in China that uses five layer co extruded nylon film (PA) to make inner bag, while other similar products in China use LDPE to make inner bag, which is far inferior to nylon film in terms of strength, tightness and puncture resistance. The inflation nozzle of the inflation bag is a special one-way check valve, which can effectively prevent gas leakage after inflation, and its special design can protect the inflation bag from being damaged during inflation and reduce the possibility of injury to operators.

In addition, one kind of inflatable bag is simply made of single-layer LDPE or HDPE, and the LDPE air nozzle with simple air nozzle but treated by special envoy is used. This kind of inflatable bag has low production cost, but the pressure is not very high.
