Yes, you can use aluminum foil facing to wrap hot food. Aluminum foil is a safe and common material for food packaging, especially for wrapping and cooking food in the oven. It's important to ensure that the foil is food-grade and not damaged or punctured, as this could lead to contamination. Additionally, avoid wrapping acidic foods at high temperatures as this can cause the foil to react and potentially release aluminum into the food. When in doubt, check the manufacturer's guidelines for safe use with hot foods.
