I experimented with plastic bag welding just now, with my butane iron and largest bevel tip. started getting good seams after a few minutes. gonna give it a rest for now, but looks like a good option for making an ultralight $5 drysuit out of garbage bags. the parchment I got for $1/pack at Grocery Outlet isn't scorching, the tip is staying clean except for the one time I touched it directly to the plastic (oops!), and the square bump pattern on the cutting board underneath seems to help rather than hurt.
