Can I use pure aluminum foil to wrap food for storage purposes?

Yes, you can use pure aluminum foil to wrap food for storage purposes. Aluminum foil is widely used for its excellent barrier properties against air, moisture, and light, which helps to preserve food freshness and prevent spoilage. It's also heat resistant, making it suitable for both refrigeration and cooking applications. However, ensure the foil is food-grade and avoid using it with acidic or salty foods as these can cause a reaction with the aluminum. Always follow the manufacturer's guidelines for safe use.
