How to prevent plastic roll static shocks?

How can I ground a large roll of plastic wrap to prevent static electric shocks when unrolling it?
At my place of work (a spa) we have a large roll of plastic, perforated into sheets that are used in some treatments. Every time a sheet is unrolled and torn off, the person doing so gets a good shock from the static electricity. Is there any way to prevent these shocks?
The plastic is wrapped around a cardboard tube, which is strung on a wooden dowel. The dowel sits into a painted metal frame which is mounted on a wood trim piece in the staff room. It's high up, so the girls stand on a metal-framed stepladder with plastic steps and with plastic feet on one side, a metal bar on the other. The ladder sits on the carpeted floor while it's used. We're up in the mountains at about 9000 feet above sea level, a very dry climate, which seems to contribute, especially during cold weather.
The whole apparatus is pretty close to plumbing and electrical boxes, conduits etc, if that helps for grounding points.
