Flour can be safely stored for up to a year in plastic storage containers, provided some basic steps are followed. When storing flour, you run the risk of it absorbing odours and moisture, so it's important to store it in an air tight, moisture proof container. You can prolong the shelf-life of flour by storing it in the refrigerator or freezer -- or a cool, dry location if that isn't an option.

  1. 1

    Choose a container large enough to hold all the flour you need to store. Consider buying more than one container if you have a significant amount of flour to store. Be sure that the container is moisture-proof and air tight.

  2. 2

    Transfer the flour into the plastic container. If the bag the flour came in is unopened, consider storing it unopened in the container for an added layer of protection.

  3. 3

    Attach the top of the plastic container tightly. Check that all the points of connection between the top and the base of the container are secure.

  4. 4

    Label the container with the date and type of flour for reference.

  5. 5

    Store the container in the refrigerator, freezer, or a cool, dry location. The colder the storage location, the longer the shelf-life of the flour.
