Pull tight security seals – Variable length plastic seals that provides a solution for an adjustable closing according to the need for security purpose sealing. The scope is very wide, namely sealing solutions of fire extinguishers, the tanks with various fluids, any kind of doors access control, fashion items sold online for return reasons, cargo trucks, concrete mixers trucks, and generally any necessity of security sealing and access control. Pull tight security seals can fit many applications from securing the neck of a bag or mail sack to sealing chemical drums, first aid kits, and fire extinguishers. They have an adjustable length much like cable seals but offer a much higher security level and an audit trail due to sequential numbering and the ability on some seals to be bar-coded and have a company name and logo printed or laser etched on.
A pull-tight security seal (or pull-up security seal) is a disposable tamper-evident seal which restricts access to closed objects for those who do not have access. The tightening security seal is needed in cases where the use of more sophisticated security measures are impossible or impractical. The security seal is not established for the physical protection of the object which is sealed, but for indicating attempts to interfere.
Layers of security
The tightening security seal (pull tight security seals) uses multiple layers of security:
an individual number;
an individual logo and barcode;
protection for the latching mechanism against direct access;
the ability to control of a condition of the locking mechanism (collet);
Any attempt to circumvent one of these protections must be visible easily and immediately.
The security seal gives users the opportunity to provide access control to objects such as warehouses, vehicles (trucks or commercial), containers, gas stations, offices, vault cash in banks, cash collection bags, slot machines, lockers, luggage, and many other objects. Also food (fish, meat, honey) and fur animals can be protected from forgery.
The design of the pull-tight security seal is configured of plastic in the form of arrows or rectangles. They have a surface for marking an individual number and latching mechanism on the one hand, and a plastic cable on the other. Like a zip tie, the cable forms a loop during mill threading into the collet, which can not be separated without damaging the cable or the locking mechanism. Its integrity is monitored through a transparent cover.
Advantages of pull tight security seals:
the possibility of visual control of integrity;
easy to install;
can not be opened without damage;
unique numbering, barcode and logo;
Disadvantages of pull tight security seals:
plastic security seal’s material is easily broken and can not serve as a fastening (lock) element.
