Although aluminium foil is an effective option for freezing food for long durations, there are some aspects that you need to consider.

First of all, the quality and properties of the foil itself determine how well it will perform inside the freezer.

As an outcome, the food will spoil even after you pack them well. So, it is better to go for other storage options such as Ziploc bags, airtight glass containers, etc.

Acidic foods like tomatoes, tomato sauce, and tart fruits can interact with the foil. After a few days, you might notice that the foil is eroded and punctured by the acids. For such foods, use plastic wraps or glass containers and not foil.
