Why are people putting aluminium foil in their freezer? It has 5 surprising cleaning and storage uses

Aluminium foil can have several practical uses in the freezer beyond wrapping leftovers. It can separate individual portions, provide an extra barrier against air and freezer burn, organise homemade foods and help protect against strong odours. However, avoid covering freezer vents or airflow channels. Acidic and salty foods should not be stored in prolonged direct contact with foil. Airtight freezer-safe containers remain best for long-term storage.
