Bags and envelopes are often closed by an integral pressure sensitive adhesive
Pressure-sensitive adhesive (PSA, self-adhesive, self-stick adhesive) is a type of nonreactive adhesive which forms a bond when pressure is applied to bond the adhesive with a surface. No solvent, water, or heat is needed to activate the adhesive ...

Documentation such as labels for certified signatures for custody and chain-of-custody labels are frequently included.
Use
No one security feature can be considered as "tamper proof". Layers of TR and TE 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, other security bags,security tape
