What is an Envopak?

Envopaks are re-usable carriers with an integral security chamber. A consumable seal is placed in the chamber for each journey to provide tamper evident protection. Originally developed in 1958, the Envopak was designed as a cost effective alternative to single use paper envelopes for the two-way transmission of mail. The environmental and cost benefits associated with using these traditional mailing Envopaks are as applicable today as they were 50 years ago.

Traditional Mailing Envopaks

Over the years the product has expanded from the mailroom environment into a variety of other applications. For example Envopak cash bags are used extensively by the banking and retail sector for handling cash and Envopak key wallets conform to British Standard BS 7499 Part 1 for key control. With an ever increasing requirement for audit trails and tamper evident protection, we have also seen the usage of Envopaks spread into the healthcare and cash in transit sectors.
