Plastic security seals are considered to be economy class seals because they are relatively cheaper than, for example, metal seals. However, using plastic seals, it is just as effective to control security and make sure that no unauthorized access, theft, etc., for example, of meters, cargo, fuel tanks, premises, etc. has occurred. Plastic seals are designed to be easy to put on and lock, as well as to quickly detect if the seal is damaged, attempted to be removed or replaced. In most cases, plastic seals can be easily removed without the use of additional tools.
