I need plastic sheeting for shelving in a wet environment. The typical application is 16" X 24" shelving -- supported only at each end (no center supports) -- which must support six evenly spaced 3 pound objects with no or insignficant flexing -- the shelving must maintain rigidity. It would also be preferable that the plastic material be FDA compliant, be available in a black or dark color, UV resistant and, of course, the lower the cost the better. In achieving compromise, the priorities would be rigidty, low cost, FDA compliancy, color, and lastly UV resistancy.
What plastic sheeting material(s) and thickness(s) would represent the best compromise of above priorities?
Thanks for any info.
