Fixed Length Plastic Seals

Fixed length plastic seals are designed for applications where sealing points remain consistent and installation speed is a priority.

Unlike pull-tight security seals, fixed length seals lock at a predetermined position. Operators simply insert the locking stem into the seal body until it clicks into place, creating a consistent loop size for every application.
This design makes fixed length seals particularly suitable for operations involving large numbers of repetitive sealing tasks where fast application and visual inspection are important.
As a direct manufacturer, we supply OEM and private label fixed length security seals to distributors, logistics providers, utility companies, retailers, and industrial users worldwide.

Many industries process thousands of sealed assets each day.
In these environments, consistency and installation speed can be as important as tamper indication.
Because fixed length seals lock at a predefined position, operators can install them quickly without adjusting strap tension or removing excess material.
This can help improve installation consistency across multiple shifts and operating locations.
Applications involving repetitive sealing procedures often benefit from:

The locking system determines both pull resistance and tamper evidence performance. Depending on application requirements, fixed length seals may incorporate:
Acetal (POM) Locking Inserts
Acetal inserts provide good dimensional stability and fatigue resistance, making them suitable for many utility and distribution applications.
Stainless Steel Locking Inserts
Metal locking inserts generally offer higher pull resistance and improved performance in applications exposed to vibration or repeated handling during transportation.
Integrated Plastic Locks
Integrated locking structures provide an economical option for lower-security applications where visual indication is the primary objective.

Security seals increasingly serve as identification tools as well as tamper indicators.
To support audit procedures and asset tracking, fixed length seals can be supplied with:

Laser marking provides improved durability compared with conventional surface printing in environments involving moisture, abrasion, or outdoor exposure. Numbering sequences are monitored during production to maintain traceability within individual production batches.

Transportation and outdoor applications expose security seals to changing temperatures, humidity, and physical handling.
Our seals are manufactured using industrial-grade polymers selected for:
Impact resistance during transportation
Dimensional stability during storage
Moisture resistance
Reliable locking performance during normal operation
For outdoor installations, UV-resistant materials are available.
Low-temperature formulations can also be supplied for refrigerated transport and cold-chain logistics applications.

Fixed length seals are most effective where locking points are standardized and repeatable. Typical applications include:

We support distributors and security product brands with flexible manufacturing options. Available customization includes:

Custom tooling projects can also be developed for exclusive products or market-specific requirements.
