Product Information

The PlatSeal is an ideal pull-tight seal for applications that require long lengths. It is designed with a stainless steel jaw that ensures a smooth pulling action while maintaining high levels of security.

Given its length, this seal incorporates additional design features such as centimeter-spaced numerical markings along the stem, allowing for precise cutting of the strap once the number has been logged. Furthermore, a tail holder is included to enable the strap to be looped back, thereby preventing the tail from protruding.

In addition, the PlatSeal is equipped with spikes that provide an enhanced grip when sealing fabric bags, reducing the likelihood of the seal slipping off during transport.

The PlatSeal is a high security seal with design considerations for its long length.
Numerical markings at regular intervals along the strap allows for cutting of the strap without losing integrity.
Once pulled through, the marking the seal is stopped at should be recorded along with the seal's unique serial number, so that the seal cannot be cut and re-inserted without evidence showing.
A tail holder has been incorporated into the tag to allow excess lengths of the strap to be looped back. This is especially useful when cutting excess strap is not desired.
Spikes are moulded into the seal to facilitate extra grip on the neck of fabric bags, so they're less likely to slip off during transit.
The insertion point is clearly embossed next to the entry hole to lower chance of mistakes during application.
The PlatSeal is able to grip onto a smooth strap using an embedded stainless steel jaw which bites into the polypropylene plastic of the strap.
