We know that food does not last forever, but with the right tools, we can certainly prolong its shelf life. Using food sealers is a new way of doing just that. 

Vacuum sealing reduces the oxygen out of food packaging and extends the lifespan of your food sources significantly. This food storage method works by slowing down the deterioration of food sources by reducing atmospheric oxygen, and creates an anaerobic environment that limits the growth of aerobic bacteria or fungi, and prevents the evaporation of volatile components.  

Due to the lack of oxygen in the sealed package, dry, solid foods like brown sugar will not dry out, freshness in sealed dry herbs extended, foods that are high in fats and oils will not go rancid, and insect infestations in dry goods will not occur. This food storage method also conserves space for additional food storage. Also, you can also use the sealer to seal non-food items to protect against oxygen, corrosion, and moisture damage. For example, you can vacuum seal unused oxygen absorbers for future food storage, matches for camping trips, medication, emergency forms, etc. 

Pros and Cons of Mylar Food Storage

With all the seen advantages, there are some drawbacks to this food storage method. Most notably, the sealed bags are not completely impervious to air. There have been multiple accounts of users saying after a few years; the bags can begin to leak. When leaks occur, the opened seals allow oxygen, insects and other enemies of your food to enter. One way to reduce leakage is to ensure that the foods you seal are not overly bulky or have sharp edges.



I have sealed beans, rice, coffee beans and popcorn and have never had a break in the seal (this is years after sealing them). In my previous article, I outlined how to use a multi-barrier method for storing food. If you add sealed foods to a 5-gallon plastic bucket, this would protect against the concern for breaks in the packaging and introduce enemies of your food.
