Storing Copper Foil

What is the best way to store copper foil?
Answer
Store it in a zip lock bag. Keep it away from high heat. Some people store it in a refrigerator if it's going to be stored for a long period of time.
The zip lock bag keeps air, which causes oxidation, away from the foil. High heat, over a period of time, deteriorates the adhesive.
