Choosing the right seal for the job
The first port of call is deciding whether to use a single use seal, or a reusable electronic seal. Once you've decided, follow the appropriate link to the left to see the products we offer. With single use seals, each type has its pros and cons, and it completely depends on the application as to which would be the best solution.
Factors that should be taken into consideration are:
The type of container that is to be secured
The temperature range and conditions where the seal will be used
The length of time the container will be sealed and whether it will be supervised
The value of the contents
The numbering system best suited for the application and process (sequential or random?)
The method of control; manual or electronic (bar-code or RFID)
The requirements for logistic management, colour or other coding
Does a third party need to approve the seal and/or procedure? (i.e. Customs)
A fixed length seal would be appropriate for sealing the doors of a truck or trailer, as in this application the seal isn't required to hold anything together, like tying a bag shut, it simply adds tamper evidence. Using a pull tight seal in this instance would put too much strain on the seal if it was pulled tight, as they are designed to be, and it could break. Not pulled tight enough, and there's a risk of tampering, as the seal would have enough length left to be able to re-thread the tail through the head, or to be glued back into place - which may not be immediately noticeable. A quick visual inspection of a fixed length seal would reveal any signs of tampering.
If a seal was required for an airline food or duty free trolley, then much like with the trailer seal example, the appropriate seal would be a fixed length seal.
However, due to the confined space on board, it would be better to use a plastic padlock seal, as these are more compact and offer single handed fastening. Unisto padlock seals are also designed to sit flush against the body of a trolley fixture, so that they are not risking being damaged during transit.
For duty free trolleys, an extra level of security is often required. The Targo seal pictured to the right is a high security padlock seal, so while having the benefits of the plastic padlock seals' easy single handed sealing, the Targo would require a thief to come equipped with cutters, which are rather difficult to carry onto a plane!
