The work aims to verify the protective effect and service adaptability of airbag sealing-type envelope in the field sealing of military equipment, so as to explore solutions for the protection of field sealing of military equipment. Based on the high-barrier aluminum-plastic laminate material and the technology of airbag pressure sealing and according to the protection requirements of field training and field deployment of military equipment, the airbag sealing-type envelope was designed, and the troops in eight typical climatic environments were selected to organize the field actual sealing test for one year. The airbag sealing-type envelope was easy to be damaged. Even if the appearance of the envelope was intact, the sealing effect was quite different: some had a good anti-rust effect, while some accelerated the corrosion of equipment. The airbag sealing-type envelope is not suitable for the field sealing of military equipment due to its structural defects, higher requirements on the sealing site, inconvenient installation and operation, and susceptibility to temperature difference.
