A pull-tight seal (or pull-up seal) is a disposable tamper-evident seal which restricts access to closed objects for those who do not have access. The tightening seal is needed in cases where the use of more sophisticated security measures are impossible or impractical. The seal is not established for the physical protection of the object which is sealed, but for indicating attempts to interfere.
Layers of security
[edit]The tightening seal (Pull-up type) uses multiple layers of security:
- an individual number;
- an individual logo;
- 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 (pad printing or laser marking).
Any attempt to circumvent one of these protections must be visible easily and immediately.
Access control
[edit]The seal gives users the opportunity to provide access control to objects such as warehouses, vehicles, 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.
Design
[edit]The design of the pull-tight seal is configured of plastic in the form of arrows. 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 and disadvantages
[edit]Advantages:
- the possibility of visual control of integrity;
- easy to install;
- high quality;
- can not be opened without damage;
- unique numbering;
- favorable price.
Disadvantages:
- seal’s material is easily broken and can not serve as a fastening element.
Security
[edit]Tamper-Evident: Pull-tight seals are designed to provide visual evidence of tampering. Once they are properly secured, any attempt to remove or tamper with the seal will cause visible damage or indicate signs of interference.
Adjustable Length: Pull-tight seals offer adjustable lengths, allowing them to fit a variety of applications. They can be pulled tightly around the item being secured, preventing unauthorized access or tampering.
Unique Identification: Many pull-tight seals come with unique identification numbers or barcodes printed on them. This feature helps in tracking and verifying the seal's authenticity and can be useful for inventory management or security audits.
Secure Closure: Pull-tight seals use a locking mechanism that securely fastens the seal in place. Once tightened, they are difficult to open without breaking or damaging the seal, ensuring the integrity of the sealed item.
Versatile Application: Pull-tight seals can be used in various industries and applications, such as securing cargo containers, securing doors, locking storage units, sealing evidence bags, and more. They are widely used in logistics, transportation, healthcare, law enforcement, and other sectors that require tamper-proof security measures.
Durable Materials: Pull-tight seals are typically made of strong and durable materials like high-density polyethylene (HDPE) or metal, which are resistant to tampering attempts such as cutting or pulling.
One-Time Use: Pull-tight seals are generally designed for one-time use. Once they have been removed or broken, they cannot be resealed, providing an added layer of security by preventing reapplication or resealing attempts.
Customization Options: Pull-tight seals can be customized with specific colors, logos, or text to enhance branding or identification. This customization can help differentiate between different security levels or indicate ownership.
Compliance Standards: Pull-tight seals may comply with industry standards and regulations, such as ISO 17712 for high-security seals used in international shipping containers. Compliance with these standards ensures that the seals meet specific security requirements.
It's important to note that the effectiveness of pull-tight seals relies on proper application and careful monitoring. Regular inspection and verification of the seals are necessary to ensure the integrity of the secured items.
