Heat sealing your mylar food storage bags effectively requires preparation and the right tools. This step-by-step guide will walk you through the process so you can enjoy the most effective food-storage tool in the industry – mylar bags!
Make Sure You Have Everything You Need Ready to Go
Ensure you have everything you need ahead of time, whether you're sealing one bag or setting up an assembly line. If you don't, you could waste time and potentially lower the effectiveness of your oxygen absorbers. Furthermore, the less organized you are, the more likely you will mislabel a long-term storage bag, which could be an unwelcome surprise 20 years down the road!
Here is a list of things to have ready to go before you start to seal your mylar bags –
· The food you want to store
· The mylar bags
· Oxygen absorbers in a sealed container
· Sharpie/Black marker
· The heat source for sealing mylar bags
· (Optional) Tape for making a label
· (Optional) 5-gallon bucket or plastic bin for long-term storage
· (Optional) Tupperware container to stand small bags in
· (Optional) Portable ironing board or timber wrapped in a towel
There are Several Common Tools for Heat Sealing
You seal mylar bags by fusing them closed with a heat source. If the temperature is not high enough, the mylar will not seal. If it is too high, the mylar will melt. Several tools typically provide the correct temperature naturally or have different settings to accommodate the project.
Here is a list of the most common tools for sealing mylar bags –
· Hair straightener
· Clothes iron
· Clamshell heat sealer
· Impulse heat sealer
· Vacuum sealer (perhaps least convenient)
8 Steps to Heat Seal Your Mylar Bags
Remember to arrange an assembly line if you plan to seal more than 1 bag. It will save time, reduce the likelihood of errors, and preserve the life of your oxygen absorbers.
