For increasing the security strength, on some models of plastic security seals has been inserted an metal component on the security lock mechanism.
So they are suitable as security sealing solution in any field of activity or any need for checking integrity control and evident tampering with of an security subject.
Security seals all plastic made are manufactured generally in two styles: with adjustable length and with fixed length.
Variable length plastic seals can fit many applications from securing the neck of a bag or mail sack to sealing chemical drums, first aid kits, online sold fashion items for wearing purpose before return, fire extinguishers, car fuel tank, and all objects surveilled for tamper evident access.
Fixed-length plastic seals tend to be more tamper resistant than variable length as there are no sliding parts, they simply ‘click‘ into place to lock, which can make them easier to fit than variable length seals. A fixed length tamper evident seal is often the choice of single use solution of security for transport applications.
Padlock seals are usually supplied as a completely plastic standard padlock seal look alike. Technically they can be classified as a fixed length security seal. The main use of this category of security seals will be the security sealing of the airline’s food carts and duty free carts for tamper evident action on protected items.
Pull-tight security seals description: a pull-tight seal (or pull-up seal) is a disposable tamper-evident security 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.
For adding an extra security layer most of the security seals will be laser engraved or thermal printed with company logo or text, unique serial number, and barcodes related to serial numbers when the security seal flag size will permitted and customer request this.
The plastic security seal is not established for the physical protection of the object which is sealed but for indicating attempts to interfere with.
