We occasionally use plastic sheeting to wrap artworks for shipping. We normally get it in rolls ten feet wide by 50 or more long. The plastic sheeting we are getting now (from our local vendors) has a great deal of the white powder on it. This powder must be cleaned off before the plastic is useable for our purposes. I understand this white powder is used in the manufacture and packaging of the plastic to keep it from sticking to itself but the plastic we got in years past had much less (if any) of it. If you know a consistent source for plastic sheeting without this powder problem, please let me know.
