Plastic security seals fall into one of thee categories: adjustable length, fixed length or plastic padlock. Plastic seals are frequently referred to as “indicative seals” as they “indicate” tampering. They are designed to show evidence of tampering and are not a security device but rather a visual indicator of tampering and theft deterrent.

Adjustable length seals allow the user to adapt the seal according to specific size requirement and can fit many applications from securing neck of a bag or mail sack to sealing chemical drums, first aid kits and fire extinguishers. Fixed-length seals tend to be more tamper resistant than variable length as there are no sliding parts, they simply ‘click’ into place to lock, which can make them easier to fit than variable length seals. Plastic padlock seals are as the name implies, shaped like a padlock and are frequently used situations where a traditional padlock would be used. All plastic security seals can be branded, numbered and /or bar coded for extra security.

Typical applications include truck doors, trailer doors, totes, vales, airline catering carts, coin bags, inner drum bags, storage bags, and any container with a hasp or loops.
