Why Polypropylene is the preferred material used when manufacturing plastic security seals.
Polypropylene is a thermoplastic polymer and is an ideal material to use when manufacturing plastic seals. The main reason for this is that the material warps and burns easily when heated in contrast to other plastics such as Nylon. If an attempt is made to tamper with the security seal and reattach two parts of the tail via a heating method the tampering would be clearly visible.
Plastic Seal Installation Recommendations
Harcor plastic seals are serial numbered. These serial numbers serve as a unique identifier. Harcor recommend having a procedure in place to record the numbers prior to use and removal. The plastic security seals should be stored in a safe location when unused. The plastic security seals include tamper evident (sometimes arguably referred to as tamper proof) features. These features could include material blushing when manipulated. All seals should be inspected for tampering before removal.
