Plastic Security Seals
Plastic seals are used to mechanically secure a variety of containers. Typical applications include truck doors, trailer doors, railcar doors, totes, valves, coin bags, inner drum bags, crime scene evidence storage bags, and any container with a hasp or loops.

Choosing A Plastic Seal
All seals are suitable for indoor or outdoor applications.
All seals have unique serial numbers. Record the serial number for added security.
Some seals have bar codes for added convenience in recording the serial number. Bar codes improve productivity and accuracy for larger projects.
Some apertures and hasp openings have small openings. Confirm the opening size and compare to the 'minimum hasp opening' for the selected seal.
Seals with shorter strap lengths cost less. Use the shortest length possible to reduce cost.
When a longer strap length is needed, reference the 'usable' length for each seal. The maximum usable length for our plastic seals is 17 inches. For longer lengths, please see our cable seals, which are available in lengths up to 54 inches.
Some seals have a higher break strength to prevent accidental breakage.
Seals with a low break strength (50 lb or less) can often be removed manually without special tools. If needed, a household scissors or wire cutter can cut the seal.
Some seals include a tear off tab for ease in removing the seal. The tear off tab also self destructs the seal so it cannot be re-used.
Some seals have 'nail grips' to help secure the top opening of a bag.
Custom imprinted seals offer more security.
Adjustable plastic seals are intended to indicate tampering for low and medium security applications. For higher security projects requiring a barrier seal, please see our selection of cable seals.
Installation Instructions
- Thread the plastic strap into the self-locking mechanism.
- Pull the strap end for a snug fit (minimize slack in the strap)
Removal Instructions
Removing the seals can be accomplished with any of the following methods:
- Use scissors or a wire cutter to cut the strap
- Firmly tug on strap (if break strength is 50lbs or less)
- Use the easy-removal tab (if included) to open the seal.
Adjustable plastic seals are a one-time use product, which can be recycled.
For Improved Security
To discourage attempted tampering, use scissors or a wire cutter to trim the excess plastic strap flush with the tab.
To minimize unauthorized reuse, snug the seal tightly initially (no slack); when later removed, use the tear tab or cut the strap near the tab bottom to assure the seal cannot be reused.
Adjustable Plastic Security Seals
All seals are in stock and ready for immediate shipment. Seals are usually sold in bags of 100 seals, unless noted otherwise.
Each bag contains seals with consecutive serial numbers. If purchasing multiple bags, we cannot guarantee the packages will be consecutive. A full case contains 1000 adjustable seals, which will be consecutive. But multiple cases may not be consecutive.
For other features and customizations not shown, please call for more information.
