A security bag is a heavy duty bag used to contain high-value products or documents or legally sensitive items. Envelopes with security features are called security envelopes as well as security bags. When used to contain items related to a crime, special evidence bags are used. Authentication of signatures and chain of custody are often required.

Construction[edit]

Security bags or envelopes may be specially designed plastic bags, paper bags, or fabric bags. Bags or envelopes can be made to be tamper resistant (TR); to make it difficult for unauthorized entry. Often it is more important for them to be tamper-evident (TE); to indicate when an unauthorized entry has occurred.

Bags and envelopes are often closed by an integral pressure sensitive adhesive on the closing flap; removal of a release liner allows convenient closing of the bag. Several types of security features can be included in the flap structure which are designed to irreversibly indicate opening.[1][2][3][4][5][6][7]

Separate security tapes are also used. Tamper-indicating security seals employ a variety of mechanisms for operation, each with its own advantages and disadvantages.

Documentation such as labels for certified signatures for custody and chain-of-custody labels are frequently included.

Use[edit]

No one security feature can be considered as "tamper proof".[8] Layers of TR and TE features, as well as the broader security systems are needed to provide better assurance of security. Most security products can be foiled by a knowledgeable person with sufficient time and with access to specialized tools, solvents, extreme temperatures, other security bags, security tapes, etc.
