Recently, we have received several questions asking why Food Insurance™ uses #10 metal cans for our long-term food supplies. Since there seems to be a lot of confusion regarding the different mediums used for long-term food storage, we would like to take a few minutes to address this question.
Why do you use #10 cans?
The simple answer is that sealed metal cans with an enclosed oxygen absorber will keep food fresh longer at room temperature than any other storage container.
There are 4 dangers when it comes to storing food, especially for extended periods of time. The dangers that present themselves are heat, moisture, oxygen and light. Sealed metal cans are one of the only storage methods that can protect from three of these for an extended period of time; moisture, oxygen and light. Heat is up to you. By placing your cans in a climate controlled environment at 72 degrees Fahrenheit or below, your food will last for 25+ years.
How do cans compare to other storage options?
Some companies choose to package their survival food in mylar bags and/or plastic containers. Mylar pouches are a great option for short-term food supplies and emergency backpacks. However, food stored in mylar bags generally only lasts 7-10 years, while the same food stored in #10 cans will last 25+ years.
There are some distinct differences between both types of storage material. Here is an illustration showing the pros and cons of each method.
