1. Function These disposable paper liners can help prevent food residues from adhering to the fryer. After use, you can simply throw away the air fryer parchment paper liner instead of cleaning the fryer again, leaving the fryer in a relatively clean state. 2. Parchment paper The baking paper is made of food - grade parchment paper. It is waterproof, oil - proof, non - stick, and has good heat resistance, able to withstand temperatures up to 428 degrees Fahrenheit. It generally does not affect the taste of the food. 【Note】: Avoid putting an empty parchment paper liner in the fryer during preheating and using too little food. Otherwise, the light - weight disposable paper liner may not be held down, and the hot air could blow the paper liner into the heat pipe, causing the paper tray to burn. 3. Unique design These non - stick disposable air fryer liners are designed in a round bowl shape. There's no need to tear, fold, cut, or bend them. They can be directly placed in the fryer when preparing to cook. The 4.5 - centimeter/1.8 - inch raised edge can help prevent food residues from splashing on the side of the fryer, and the food can be taken out relatively easily through the raised edge. 4. Does not interfere with internal air circulation Heat is generated through the air circulation in the pot wall. So, even without holes, using these air fryer parchment papers usually won't affect the air circulation. Compared with perforated air fryer papers, they can help prevent food residues from adhering to the bottom of the fryer. During baking, the oil will flow onto the paper liner, enabling you to enjoy relatively healthier food. 5. Packaging list The product comes with 50 or 100 disposable paper liners.
