Security bag

Bags or envelopes can be made to be tamper resistant to make it difficult for unauthorized entry.

It is often more important for these to be tamper evident so that an unauthorized entry is easily detected to have occurred.

The removal of a release liner allows 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.

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