The Plastic Truck Seal is the strongest plastic fixed length seal in the Navacqs range. With a breaking strength of 28 kg, it provides a secure closure for truck doors, empty containers, and rail wagons. The seal has a fixed operating length and can be applied quickly and easily by hand. Designed to withstand various weather conditions, it ensures lasting protection. Each seal is supplied with the imprint “PTS SEALED” and a unique serial number. Custom printing with your own company name or logo is also available upon request.
Built for demanding applications, the Plastic Truck Seal combines strength with reliability. The wide 10 mm strap and reinforced body make it highly resistant to breakage. With its 28 kg breaking strength, it offers dependable sealing performance for heavy-duty transport operations where tamper evidence is essential.
The locking mechanism is equipped with a Delrin® (Acetal) insert, a high-performance engineering plastic often used as a substitute for metal. This insert enhances locking strength and ensures a tight, tamper-evident seal. Once closed, the Plastic Truck Seal cannot be reopened without visible damage.
Despite its robust construction, the Plastic Truck Seal is quick and easy to apply. The tapered end of the strap smoothly clicks into the locking chamber, providing an audible confirmation that the seal is securely fastened.
Manufactured from high-density polyethylene (HDPE), the Plastic Truck Seal offers outstanding resistance to chemicals, UV light, and temperatures ranging from -40°C to +80°C. This combination of stiffness and flexibility ensures long-lasting durability and ease of use, even in harsh outdoor environments.
The Plastic Truck Seal is designed specifically for securing truck and container doors. Its fixed length provides a consistent, safe fit without excessive tension, minimizing wear. Weather resistance makes it ideal for extended use in transport, logistics, and storage operations.
Each Plastic Truck Seal features a one-time printed serial number and imprint, guaranteeing traceability and preventing duplication or tampering. Customization options include company logos, text, or barcodes for enhanced identification and brand visibility.
You can make the Plastic Truck Seal even more distinctive by adding your own imprint. For example, you can include your company name, logo, or custom text. Below are the available customization options:

A Plastic Truck Seal is a plastic fixed length seal with a fixed length and a breaking strength of 28 kg. The seal has a wide 10 mm strap and a closure with a hard plastic core (acetal).
That core sits in the locking mechanism and clamps the strap in place as soon as you press it in. Small teeth on the inside block the strap, meaning the seal can't be pulled back out.
The seal is closed by hand and can then only be removed by cutting it or pulling it off with force.
Applications:
trucks
empty containers
train wagons
A Plastic Truck Seal is used to seal doors and closures that move or come under tension during transport.
On a truck door, for example, driving, braking and vibration create movement and slack. This puts pulling force on the closure. A thin or weak seal can then stretch or come loose.
The wider strap and strong closure of the Plastic Truck Seal keep the seal in place, even under force.
In practice:
you thread the strap through the door closure
you click the end into place
the seal stays in place despite movement and tension
opening is done by cutting or pulling off with force
The Plastic Truck Seal has a breaking strength of 28 kg. This means you can't open the seal by hand without effort.
The higher strength comes from two things:
the wide 10 mm strap, which deforms less easily
the hard plastic core in the closure, which clamps the strap and doesn't give
This keeps the seal in place under pulling force on the closure, such as doors that move during transport.
