HIGH QUALITY DESIGN -they 't rip or tear while you are using them The silicone oil coating on both sides makes it much easier to separate food. The papers are also water-proof and oil-absorbing, and can be put into the microwave or oven. COMPATIBLE WITH MANY PRESSES - Used with a variety of pressing tools, our paper size is 4.5 inch round, which is suitable for a wide range of the most common burger pressing tools. You 't find yourself wasting time trying to peel sticky patties off the press when you use patty papers to the meat's direct contact with the press. This is also more sanitary and reduces contamination. MULTI PURPOSE - Don't limit your ideas to just separating hamburger patties. You can also use these papers with cheese, pre-cut meats, foods for the grill, cold cuts, and whatever else you can think of. SAVE PAPER - The small pre-cut papers make meat separation more efficient and the circular size means less waste. As an eco friendly bonus, these papers can also be used for composting. YOUR SAFTY IN MIND - We use double-layer protection and a safe and clean bag in our packaging to avoid moisture and dust. Wrinkles can be flattened with heavy objects.
