Why is double wrapping used when transmitting classified materials?

Double wrapping classified materials is primarily used to ensure that the material remains secure and protected, even in the event that the outer wrapper sustains damage. This method provides an additional layer of security, preventing unauthorized access to sensitive information. If the outer layer were to be compromised, the inner wrapping still protects the classified material, thereby minimizing the risk of exposure or loss.

This practice is crucial in safeguarding national security and maintaining the integrity of classified communications, as it mitigates the possibility of accidental or intentional disclosure of sensitive information. The redundancy of double wrapping serves as a critical control measure in the transport and transmission of materials that require heightened security protocols.
