Effective Tips for Storing Flour in Mylar Bags for the Long-Term

If you are a person who enjoys cooking and baking, then you must know the importance of having flour in your pantry. Flour is one of those essential ingredients without which most baked goods cannot be made. However, if you buy too much flour at once or want to store it for an extended period, then storing it can become a problem. The solution to this problem is using mylar bags.

Mylar bags are a popular choice for food storage because they protect food from moisture, light, and oxygen. They are also durable and puncture-resistant, making them ideal for long-term storage of dry foods such as flour.

In this blog post, we will discuss how to store flour long term in mylar bags.

Step 1: Choosing the Right Mylar Bag

Before storing your flour in mylar bags, make sure that the bag is suitable for food storage. Not all mylar bags are created equal; some may not meet FDA regulations or have not been designed specifically for storing food items like grains or flours.

Make sure that the bag has a thickness of at least 5 mils (0.005 inches) so that it can provide adequate protection against air and moisture. Additionally, ensure that the bag has an oxygen absorber included with it or purchase separately as removing oxygen from inside the bag prevents spoilage due to oxidation.

Step 2: Preparing Your Flour

Once you’ve chosen your mylar bag(s), make sure your flour is bone-dry by oven-drying before packing into Mylar Bags otherwise trapped moistures may lead to mold growth within few days ruining all efforts put into proper packaging..

Step 3: Filling Your Mylar Bag

After prepping your dry ingredients , pour them into each myarla bag ensuring there’s enough space left over at top about two-thirds empty. This will allow for proper sealing of the bag. Additionally, adding an oxygen absorber to each bag can help increase storage life.

Step 4: Sealing Your Mylar Bag

The final step is to seal your mylar bag using a heat sealer preferably with double seals and cut off excess plastic (about 1-2 inches) strategically placed too close to the top of the contents while leaving enough space beneath it so that you have a good grip on it when opening. Make sure there are no air pockets or holes in the seal because this could expose your flour to moisture, light or air which would reduce its shelf life.


In conclusion, storing flour long-term in mylar bags is an excellent way to ensure that your flour stays fresh for a long period without compromising quality and flavor. However, following these guidelines carefully should be taken as improper sealing or packing may lead spoilage within weeks instead of months due exposure of stored items from moisture/air/oxygen/light sources hence negating all benefits offered by Mylar Bags.
