Charles Viancin Banana Leaf Lid

The silicone lid creates an airtight seal on any container with a smooth, flat rim, including glass, ceramic, stainless steel, and plastic. It will not work on textured or chipped rims, as the seal requires a completely flat surface to suction properly.

Yes, the lid is oven-safe up to 428°F. It is designed to handle high heat, making it perfect for covering dishes while they bake or keeping food warm before serving.

High-quality, food-grade silicone is generally non-porous and resistant to odors. However, if you store particularly pungent foods, a thorough wash in the dishwasher or a soak in hot, soapy water typically removes any lingering smells.

While the lid is rectangular, the flexible silicone material allows for some leeway on containers that are slightly smaller or have rounded corners. As long as the container rim is smooth and the lid can make full contact with the surface, it will create a secure seal.

For the strongest seal, ensure both the rim of your container and the underside of the lid are clean and dry. Once placed on top, simply press down gently on the center of the lid to release excess air and create the vacuum effect.
