‘Security seals’, whose body and lock system are made of plastic, are called plastic seals. Plastic security seals indicate to the user that a breach has occurred, with traces of tampering, if the sealed product or load has been tampered with. When an undesired intervention occurs on the seal, there is a permanent deterioration in the seal structure and the integrity of the seal cannot be restored.
Some models of plastic security seals have metal components added to the locking mechanism for added security. These metals placed inside increase the resistance shown against destruction of the seal by creating resistance against tampering.
Plastic security seals protect the integrity of the seal by resisting tampering, do not allow any component of the used seal to be replaced with a seal of similar design, cannot be regenerated, and leave visible evidence of any attempt to open the seal once a correct seal has been achieved in the field of application.
Plastic Seal Types
Plastic security seals are generally produced in two types. These are plastic seals with adjustable length and fixed length.
Adjustable length plastic seals can be used in many applications, from securing the neck of a bag or mailbag to sealing chemical drums, first aid kits, fashion items sold online for wear before return, fire extinguishers, car fuel tanks and any tamper-evident objects.
Adjustable length tightened plastic seals are a disposable, tamper evident security seal that restricts access to closed objects for those without access.
Strap seals are in the category of adjustable-length plastic seals and are the most widely produced type of security seal. It has a wide range of designs. It is generally produced from polypropylene (PP). It has many applications such as airline and food service carts, fuel tankers, oil tankers, trailer doors, container doors, cash carrier, gaming machines, mail bags, fire doors, lockers, evidence boxes.
