If you’re applying a dusting of cinnamon or something similar to foam on a beverage through a laser cut stencil, I’d test Butcher’s Paper. It’s food grade,dark enough to respond to blue light consistently and thin enough to not drop much (if any) carbon into the coffee.
I recommend an abundance of caution when engraving paper especially with any kind of air assist or forced air smoke extraction. Some paper (and some types of cardboard) will suddenly catch fire. Do not leave the laser engraver unattended.
For a blue laser, white or semi-translucent plastics will pass the light until they start to char then suddenly change to absorb light quickly. This makes it fairly challenging to control and get a clean edge. If you’re going to test polypropylene, pick a dark color that blocks blue light.

to be honest: never heard of butcher paper… the literal translation would be Metzger Papier … since it is sold on rolls, I think it is too wobbly / floppy … actually I was thinking of something dishwasher safe
has anyone had experience with butcher paper?
Haven’t used butcher paper, although I’m familiar with it.
I cut targets out of watercolor paper… It’s rather thick and allows you to handle it… and it’s cheap. Probably be a one shot item.
