How to Seal Your Own Food with Mylar Bags

by Shawn Barrington 02 Jan 2024

Metalized bags, or Mylar bags, offer a great solution to sealing your own food. Mylar bags help keep moisture, sunlight, and oxygen out of your food – extending your food’s shelf-life! Here is a step-by-step tutorial on how to seal your own Mylar bags.

What you’ll need

First, be sure to round up all of your supplies. It’s recommended that you seal more than one Mylar bag in a sitting because the oxygen absorbers that you place in the bags can only stay out in the open for a few hours. So, you can’t really open the O2 absorber bag and then use the absorbers later.

Be sure to gather:

• Your food

• A bucket (doesn't need to be food-grade)

• A lid

• Mylar bags for each bucket

• An oxygen absorber for each bucket

• A heat source like a clothes iron or a hair straightener

 

Step 1 – Put the Mylar bags in the buckets

Be sure to spread the bag out along the bottom of the bucket as much as possible. This will help you food settle to the bottom as much as possible.

Step 2 – Pour the food into the Mylar bag

Step 3 – Lift the Mylar bag to settle

Take the Mylar bag and lift it up inside the bucket. Don’t take it out. Shake the bag to make sure that all the contents are settled to the bottom. This will help the food fill into the pockets of air in the bag so you can get more food into the bag.

Step 4 – Throw in an oxygen absorber

You don’t have to bury it or anything. You can just throw it on the top. You’ll want to press the sides of the bag so the part you’ll be sealing stands straight. This is a good time to push out the remaining air.

Step 5 – Seal the bag

Use a clothes iron or hair straightener to seal the top of the bag. If you use a clothes iron, make sure that it’s not on a steam setting. The heat source should be at a high setting to seal the bag correctly.

When using a clothes iron, it is sometimes helpful to use a piece of wood to iron against. You can wrap the top of the bag around the wood and push against it to iron. Start heating from the middle of the bag and move your way to the outside. This will help the seal lay more evenly.

We’ve seen a lot of videos where people leave a slot at the top of the seal, quickly vacuum out the remaining air and then seal the rest of the bag. This isn’t necessary. If you have a good oxygen absorber, it will take out the remaining oxygen from the bag.

You might notice there is still some space in the bag due to nitrogen in the air, which doesn’t harm the food. A 2000cc oxygen absorber is potent enough that if you were to inflate the entire Mylar bag with air and seal it with the absorber, it would take all the oxygen out, leaving only nitrogen and traces of other gases (less than 1 percent) that are not going to harm your food.

Step 6 – Place a lid on top

Fold over the Mylar bag and then place a lid on top. You’re done! What other tips do you have? What have you found to be effective for food storage? Comment below and let us know.
