Ensure security against tampering with our Standard-Duty Plastic Security Seals which are suited for multi-purpose sealing, shipping, and protecting valuable items. These plastic seals are single-use and are made from strong yet relatively light and easy-to-use polypropylene. Their self-locking feature makes them hold tight making them useful for locking containers, doors of trucks, cash bags, utility meters, and much more. These security seals are sold in increments of 1000 which is, in fact, one pack. For better management and control, these seals are marked in number order, so auditing does not become a challenge.
