Asecurity bagis a heavy duty bag used to contain high-value products, documents or legally sensitive items. Envelopes with security features are calledsecurity envelopesas well as security bags. Cash for deposit in a bank is often placed in a specialdeposit bagwith security features.[1][2]When they are used to contain items related to a crime, specialevidence bagsare used.[3]Authenticationof signatures andchain of custodyare often required.

Construction[edit]

Security bags orenvelopesmay be specially designedplastic bags,paper bags,or fabric bags. Bags or envelopes can be made to betamper resistantto make it difficult for unauthorized entry. It is often more important for these to betamper evidentso that an unauthorized entry is easily detected to have occurred.

Bags and envelopes are often closed by an integralpressure sensitive adhesiveon the closing flap. The removal of arelease linerallows convenient closing of the bag. Several types of security features can be included in the flap structure and are designed to indicate its opening irreversibly.[4][5][6][7][8][9][10]

Separatesecurity tapesare 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".[11]Layers of tamper-resistant and tamper-evident features, as well as the broader security systems are needed to provide better assurance of security. All security products can be foiled by a knowledgeable person with sufficient time and with access to specialized tools, solvents, extreme temperatures,[12]other security bags,security tapes,etc.
