get tired of hearing POP POP POPPPOP all day long - there is a flat plastic sheet available for protecting items. I don't quite know what it's called but a stationery store might help out. It's somewhat opaque with a milky-white color. I looked around here to see if I could find a shred of it left (only had a small amount to begin with) so I could attach a scan - but think it's all gone.
