Xerox pre-die cut paper?

While working with a previous printing company with a Xerox IGen, we had access thru Xerox to some pre-die cut papers. They might have been synthetic papers. Now I can't find them anywhere and I don't remember how to get ahold of the contact at that company. Now working at a new company and have a customer inquiring about something I'm sure I could get before using these products from Xerox. New company hasn't heard about this stuff - anyone know whom to contact at Xerox about it? There were CD and DVD mailers, candy boxes and all sorts of stuff on 12 x 18 sheets that were pre-die cut. You'd image them, then punch them out and assemble them. Help??
