The work aims to study the long-acting packaging technology for equipment protection in islands. The significance of long-acting packaging technology for the equipment protection in islands was clearly defined. A comparative study was carried out on the packaging technologies of equipment suitable for the islands, such as envelope sealing technology, dry packaging method, gas phase antirust packaging method, antirust oil packaging technology, nitrogen charging packaging technology and antistatic electromagnetic shielding packaging technology. The comprehensive application of long-acting packaging technology combined with multiple technologies and methods could play an excellent role in the protection of equipment in islands. The comprehensive application of long-acting packaging technology can effectively reduce the adverse impact of the island environment on the equipment, and is of great significance for ensuring the performance of equipment; therefore, it is necessary to increase investment for in-depth research.
