Plastic security seal, we also call it indicative seal. They are intended to show evidence of theft, destruction, or tampering. Generally, plastic seals play an anti-cheating and anti-tampering role in the election to ensure fairness.

But this does not mean that all plastic seals can be prevented from being disassembled. In our tests, it is very easy to unpack and re-lock the seal without breaking the seal if the operator used it improperly. Our results show that the seal is easier to disassemble in the form of a round strip, and some flat strips, even if there has a metal piece in its keyhole.

Therefore, generally, we will recommend our SE-SLP001 plastic seal as a ballot box seal. So far we have not found that the plastic seal can be taken apart and re-locked without breaking the seal.

Plastic seals are generally classified into two kinds of lengths, the adjustable lengths and the fixable lengths. The fixable length seals tend to be more tamper resistant than variable lengths because there are no sliding parts,. They can be locked by simply "snap" in place, which it’s easily to install than variable length seals. However, the seal can only serve as a sign and a reminder, due to the fixed length seal cannot lock the ballot box tightly.

The users can adjust the length of the plastic seal which is adjustable according to their applications. They can use the seal from the locking of the neck of a fixed bag or pouch, to using it in the first aid kits and fire extinguishers. During the election, the seals must be locked tightly, so that the lid and the box can be fastened together completely. It can make ensure that anybody is prevented from illegally penalizing the ballot during the election.
