Teslin is a waterproof synthetic printing medium manufactured by PPG Industries. Teslin is a single-layer, uncoated film, and extremely strong. Its official website states that it is recyclable and non-toxic. The strength of the lamination peel of a Teslin sheet is 2-4 times stronger than other coated synthetic and coated papers. Available thicknesses run from 7 mil to 18 mil, though only sizes 10 mil and 14 mil are sized at 8.5" by 11" for printing with most consumer printers. Also available are perforated versions, specifically, 1up, 2up, 3up, 6up, and 8up.
