Pull tight security seals are variable length plastic seals that provides a solution for an adjustable locking according to the need for security purpose sealing.

The scope is very wide, namely control access or tampering evidence on fire extinguishers, the tanks with various fluids, chemical drums, security of the neck of a bag or mail sack, any kind of doors access control, first aid kits, fashion items sold online for return reasons, cargo trucks, concrete mixers trucks, and generally any necessity of security checking along the route and access control.

The adjustable closing length seals offer maximum security against tampering and ensures traceability of valuable goods at an very low price cost.

The pull tight plastic seals are disposable items in other words they are designed only for a single use.

Pull tight security seals 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.

Pull tight seal or adjustable closing length plastic seal

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.

Users can adjust these adjustable length plastic seals to the needed closing fit and tightness which is particularly useful for securing different types and sizes of items that have to be security protected and checked for tampering with on the transport routing.

The pull tight security seal is not established for the physical protection of the object which is sealed but for indicating attempts to interfere with.

For an superior endurance or security strength some pull tight security seals have an metallic insertion layer on the security locking mechanism.

1. 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);
• a material of collet production;
• labeling method (laser marking, pad printing or thermal transfer printing) which made your identification unique.

Any attempt to circumvent one of these protections must be visible easily and immediately. This is why they are often named anti tamper seals.

2. Access control

The anti tamper security seal gives users the opportunity to provide access control to objects and items 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 when they are stored in a security protected box with the variable length plastic security seal.

3. Design of anti tamper seals

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 can be monitored through a transparent cover or by the broken plastic cable. Some of the pull tight security seals have an added metallic locking mechanism for a high grade security level when this is requested by sensitive applications like Cash In Transit security of the bags, boxes or ATM cassettes.

Advantages of pull tight security seals:

• adjustable length of closing for various shapes and sizes of items to be sealed;
• the possibility of visual control of integrity;
• easy to install;
• high quality materials of seal body and locking elements;
• can not be opened without damage;
• unique numbering, barcode, and logo;
• favorable price.

Disadvantages of pull tight security seals:

• plastic security seal’s material is easily broken and can not serve as a fastening (lock) element;
• single use seals.
