Acrylic or polycarbonate sheeting is the the first thing to come to mind.
If you attach a smaller piece of acrylic to a flexible arm then to a magnetic base, you could then simply position it in the path of the offensive, flying chips rather than having a relatively large sheet that you have to clean and store. Just a thought.
Oh - you do wear safety glasses, right?
