Made of pet, clear PAC safe seal containers are specifically designed to inhibit tampering, eliminating the need for shrink bands and wrap labels. The tamper alert hinge protrudes outward when torn, alerting the customer that the container has been opened. The hinge remains attached to the container, for no loose plastic pieces. Clear PAC safe seal containers function as an easy to re-close and re-open, leak resistant two piece container once the hinge is torn. Clear PAC safe seal has exceptional performance in cold temperatures and accommodates freezing down to -22°f.
