- Upgraded design based on customer feedback We are a professional kitchenware producer focused on customer experience. We collect suggestions from customers on similar products sold on Amazon and upgrade our products based on data from negative reviews to provide better kitchenware. - 446 F heat resistance and safe materials The liner uses food-grade liquid silicone (the same material as baby nipples) to wrap fiberglass, improving heat resistance and preventing melting in the oven. It preserves aroma and avoids smells or smoke, addressing a common customer need. The inner fiberglass weave ensures even heat distribution, helping prevent uneven doneness whether you are roasting vegetables or baking cookies. - Durable edge treatment with twice glue-dipping After cutting to the required size, edges are coated to prevent peeling. We upgrade to a twice glue-dipping process for a sturdier edge that resists fraying. Edge thickness is 0.8 mm, balancing rigidity with flexibility. Suitable for cooking tasks such as chicken wings, fish, and roasted vegetables, as well as baking tasks like biscuits, macarons, churros, and icing practice. - Non-stick and non-slip performance The liner is non-stick, so nothing sticks and cleanup is easy. Cookies and macarons release cleanly when cooled, and the surface helps keep pans clean. It also stays in place during use and won’t slide around like paper sheets. - Use scenarios - Roast vegetables or bake cookies on the liner for even browning and easy release. - Bake delicate items such as macarons, biscuits, churros, or icing practice without sticking. - Use for general oven cooking of chicken wings or fish with easy cleanup and reliable heat distribution.
