The Straplock security seal has been developed to secure polypropylene strapping where it crosses, to ensure pallets and cartons can be security sealed to provide tamper evidence during transport.


The bottom part of the Straplock security seal is placed under the crossed section of the strapping, and the top part placed over it. The Straplock tool is then used to secure the two pieces together. Each part of the seal carries the seal number, which are supplied sequentially in 7 digits, to prevent substitution.

Two versions of the Straplock are avaliable to cover different strapping widths.

We supply two tool options for the Straplock; Manual or electric. For more information on how each tool works, please see the videos below:
