Yes, aluminum foil can be used in the oven. It is a common practice to use aluminum foil when cooking or baking certain foods in the oven. Aluminum foil helps to distribute heat evenly, prevent food from sticking to the pan, and can be used to cover dishes to prevent them from drying out.

Avšak, there are a few important considerations to keep in mind when using aluminum foil in the oven:

1. Check the manufacturer’s instructions: Ensure that the specific brand of hliníková fólia you are using is labeled as safe for use in the oven. Some types of foil may not be suitable for high-heat applications.
2. Use as a lining or covering: Aluminum foil is typically used as a lining on baking sheets, panvice, or as a covering for dishes. It can help with easy cleanup and prevent food from sticking. Avoid using aluminum foil as a cooking vessel by itself, as it may not be able to withstand the weight or may tear.
3. Avoid direct contact with heating elements: If you’re using aluminum foil to cover a dish or wrap food, ensure that it doesn’t come into direct contact with heating elements such as the oven’s heating coils or burners. Direct contact can cause the foil to melt or catch fire.
4. Be cautious with acidic or salty foods: Aluminum foil may react with certain acidic or salty foods, causing them to break down and potentially affect the taste or quality. To avoid this, you can place a layer of parchment paper between the food and the foil.

Remember to always follow safe usage guidelines and consult the specific instructions provided by the manufacturer of the aluminum foil you are using to ensure its suitability for oven use.
