I think you're mistaken about cutting boards. A 1/4" thick x 12" x 24" piece of PTFE (Teflon) costs $~200 (http://www.amazon.com/dp/B000ILHVXU/ref=biss_dp_t_asn), so the ~10 sqft the OP is looking for would cost ~$1000, assuming you could find a single piece that large. I suspect that's a little more than anyone wants to spend for a print bed to which parts won't stick. A quick perusal of these forums will demonstrate the myriad, much less expensive ways people have found to make beds to which parts won't stick. Generally speaking, parts need to stick to the bed in a 3D printer because when they don't, the print fails.
You're probably thinking of PE or HDPE. It's cheap stuff, often used to make cutting boards, and it's sort of white like teflon. It has a very low melting temperature (about 130C) that would make it unsuitable for use as a print bed material, even if parts could be made to stick to it.
