The following are just some criteria you can use to decide which seal to buy:


SEAL TYPE

1. VARIABLE LENGTH / PULL-TIGHT

  • Like a belt that can be tightened

  • Used where seals must be snug onto the item to avoid pilfer

  • Example: cash / courier bags. bags, tanker valves, fire extinguishers, emergency device, atm cassette box

2. FIXED LENGTH - sometimes called LOOP SEAL

  • Forms a loop like a bracelet once locked.

  • Used where seals should have an allowance for movement

  • Example – truck doors. container vans doors, bonded warehouse.
