ProAmpac’s KeepSafe® tamper-evident security bags are known worldwide as the premier, established brand in the loss prevention industry. KeepSafe product technology prevents evidence from being compromised and supports good chain-of-custody procedures. These bags are made from durable polyethylene film and come preprinted with all information required for proper evidence submission. And our teams' expertise in coextruded films gives KeepSafe products the advantage of lighter and stronger plastic materials, contributing to the sustainability of our product while reducing freight costs.

With enhanced closure features, KeepSafe's tamper-evident properties are distinguished by three levels of security:

  • Ultra – For high-risk applications, protects from all known methods of attack
  • Premium – Designed for mid-level tamper evidence
  • Secure – For lower-risk applications

We also offer bags specifically designed for collecting and securing wet evidence. These bags feature a breathable material on one side that facilitates the drying of wet evidence and guards against the loss of crucial evidence due to deterioration.
