Question, which kind of mesh needed for a dry ice hash bag.

Hey all, I don't know if this is the right place to ask, but I wanted to build myself a dry ice bag. My question is if anyone knows what kind of Mesh I would be needing, Fine Silk Mesh? Stainless Steel Mesh? ect. and where I could purchase it.
Also, if anyone knows the difference between stainless steel mesh and Silk mesh when used to do dry ice extraction.
Sorry, if this was not in the right forum.
