One of the common issues with laser cut IR patches is that the laser cut layer can begin to separate and peel over time. This is especially true at the corners. Perroz Designs just introduced their Gen 3 IR Patches that use a folded edge to secure the edges and corners. This new edge treatment prevents the laser cut Cordura layers from delaminating from the luminous material layer below which in turns makes for a more durable patch.
