How to Seal a Mylar Bag in a 5-gallon bucket


Fill and seal a Mylar bag to use inside of a cheap five gallon bucket for long term food storage.
Unless you are finding food grade five gallon buckets for free from your neighborhood bakeries, etc.., instead of spending the money on food grade buckets, spend the money on cheap five gallon buckets at your home improvement center and use the extra cash you save on that purchase to buy yourself some Mylar bags, Oxygen absorbers, and Gamma Screw Top Lids.
The Mylar bags will completely seal the food. The seal, along with an oxygen absorber will eliminate any buggies that may already be in the food, and keep the food fresh in the absence of oxygen.
The Gamma lids lids will make your life much easier when it comes time to break in to your five gallon buckets for usage. They also seal air tight with a rubber O-ring gasket on the ring and the screw top lid.

How to seal a Mylar bag for long term food storage

If using a Gamma Screw Top Lid, snap on the gamma ring to the top of the bucket.
Insert a Mylar bag designed to fit a five gallon bucket.
Dump the food stuff into the Mylar bag to keep for long term storage (e.g. long grain white rice). Be sure to leave about an inch space from the top of the bucket to ensure that the lid will screw on, and the excess Mylar bag material will stuff inside.


Add a 2,000 cc oxygen absorber to the filled bag. Oxygen absorbers come new in a sealed bag. When the bag is opened, the oxygen absorbers should be used immediately and any extras should immediately be stored in a glass mason jar.

Use a flat board or any flat smooth object to lie underneath and across the open end of the Mylar bag. This will assist making the seal.
Use a hot Iron to press and seal across the open seam of the Mylar, while stopping just short of the end, leaving an opening to burp out the excess air.
An Iron heat seating from three-quarters to full heat will work OK. The Iron will not melt the Mylar to goo, so don’t worry. My Iron has remained clean throughout. Run the Iron across the seam a few times while pressing mildly.
Burp out the remaining air that is inside the Mylar bag through the small open end that has not yet been sealed. The oxygen absorber will pull out the rest of the air afterward, so don’t worry about squeezing all the air out.

Position the open Mylar corner at an angle compared to the original ironed seam, place the flat board underneath and Iron across a few times to make the final seal.
Fold the excess of the Mylar bag into the five gallon bucket and wait 12 hours before checking back to be sure the oxygen absorber pulled the remaining air out of the bag. This will let you know that the Ironed seal is good to go. The bag should have a vacuum crumpled look.

I like to leave a nutrition note inside the bucket. Definitely be sure to label the outside of the five gallon bucket with the ingredient as well as the year and month. I like to use white artist’s tape, which sticks well to things and is perfect for labeling.
