Product Information
The PlatSeal is a premium pull-tight security seal designed for applications requiring extended lengths and flexible use. Built for strength, reliability, and precision, it features a robust stainless steel locking jaw that delivers a smooth yet firm pulling action, ensuring both ease of application and a high level of tamper resistance. This combination of functionality and security makes the PlatSeal suitable for a wide range of industries, from logistics and transport to cash handling, postal services, and air cargo.
Its extended strap length allows it to secure large or irregularly shaped items such as mailbags, tote boxes, courier sacks, and warehouse storage containers. For added practicality, the PlatSeal includes centimetre-spaced numerical markings along its stem, allowing users to measure and record exact lengths for consistent application and easy tracking. Once the seal number has been logged, the strap can be trimmed neatly to size, improving both presentation and safety.
A built-in tail holder ensures a tidy finish by allowing the excess strap to be looped back and locked in place, preventing any unwanted protrusion that could catch or snag during handling. Additionally, integrated spikes on the strap provide an enhanced grip when used with fabric or woven materials, minimising slippage during transport and ensuring the seal remains securely fastened.
Manufactured from high-quality, durable polymer materials, the PlatSeal is designed to perform reliably in demanding environments and under varying conditions. With options for custom colours, sequential numbering, barcodes, and branding, it provides an effective and professional sealing solution for businesses seeking both security and operational efficiency.
