If it is a poly vinyl it is probably PVC based which is a definite no no. The fumes creared will damage the laser.

We use Rayzist's LazerMask. We have a 40 watt laser and use a setting of 60 speed and 100 power which according to Rayzist is overkill but since it works for us that is what we use.

Hope this helps,
Dave
