Can Aluminum Foil Be Used in the Freezer?

Aluminum foil is a great solution for storing things in the freezer. Properly used, aluminum foil stores food for the maximum duration possible for the type of food wrapped.

Heavy-Duty

Use heavy-duty aluminum foil for the freezer. The other kinds of foil don't stand up to low temperatures, becoming brittle.

Long-Term Storage

When storing food for the long term, the North Dakota Extension Service advises removing the original wrap before using foil.

Dry-Food Storage

Aluminum foil should only be used to freeze dry or low-moisture foods. Foods that include liquids should be stored in freezer containers instead.

Barrier

Air and moisture are enemies of long-term freezer storage. Heavy-duty aluminum foil creates a barrier against air and moisture.

Acidic Foods

Acidic foods frozen in foil may taste bitter or metallic later, according to the University of Missouri Extension. Additionally, food may undergo color changes and the foil may begin to corrode.

Thickness

If the aluminum foil isn't labeled "freezer" or "heavy-duty," see if thickness is listed. You'll need a thickness of at least .0015 inches.
