Made of PET, ClearPac® SafeSeal™ containers are specifically designed to inhibit tampering, eliminating the need for shrink bands and wrap labels. The TamperAlert 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. ClearPac® SafeSeal™ containers function as an easy to re-close and re-open, leak resistant two-piece container once the hinge is torn. Features exceptional performance in cold temperatures and accommodates freezing down to -22°F. Domed lid.
