The plastic is heavier then a grocery bag. I would say it is similar to
a heavy duty plastic drop cloth. The mesh is used to make sure the
plastic is not over stressed from the pressure of the gas.

What kind of plastic membrane works the best? Can I just use a plastic
bag from the grocery store, or should I try something else? I'm not
sure I understand the role of the wire mesh, either.
