The TFX Non-Stick! All-In-One Kitchen Sheet replaces parchment paper, foils and can also be used as an oven liner. It promotes healthy eating by eliminating non-stick sprays, butter and oils. The TFX Non-Stick! is made with glass fibre coated with 4 layers of PTFE (polytetrafluoroethylene, aka Teflon.) The PTFE coating will prevent anything, including bacteria, from sticking to the sheet. Simply place the item you want to cook or grill directly on the sheet. It is terrific for cooking pizza, eggs, chicken, steak, fish, vegetables and much more. TFX is excellent for baking cookies, cakes and breads. First knead the dough on the sheet then watch your goodies slide right off the sheet once they're baked. Place the TFX Non-Stick! at the bottom of your oven to use as a non-stick oven liner and your oven scrubbing days are a thing of the past. TFX is good for the environment with one sheet usable 1,000+ times at 260°C (500°F).
