Yes, you can use aluminum foil to wrap food in the freezer. Aluminum foil is a good insulator and can help protect food from freezer burn. It also prevents cross-contamination and keeps odors from affecting other foods. Ensure the foil is tightly wrapped around the food to maintain freshness and quality. However, for long-term storage, it's recommended to use airtight containers or freezer-safe plastic bags in addition to or instead of foil, as they can provide better protection against freezer burn and moisture loss.
