Vacuum sealers do heat seal mylar bags effortlessly while smoothly removing all the excessive air out of the bag, at the same time. This bit-specific sealing method removes all excessive oxygen from the heat-sealable food bags, keeping the edibles potent and safe for a longer period.

• Clothing Iron 

Sealing mylar bags with the help of a household clothing iron is a safe and doable way to seal the mylar bags. This essential electronic appliance is present in every other house, so this method is a piece of cake for everyone. It is much easier and less hectic than ironing a shirt. 

So, all you have to do is to just simply turn the iron on. Then pass it slowly over the bag opening end, not more than twice. A great seal is done on the heat-sealable Mylar bags. 

• Hair-Straightener 

Heat sealing the mylar bags via a hair-straightener is also a very easy-peasy way to seal the deal. A hair straightening iron of good quality simplifies the task for you. And trust me, this heat-sealing method requires much less effort and precision, as compared to when making your hair all prim and proper. 

All that is required is just carefully place the clamps of the hair iron on the topmost ends of the bag. Run the straightener back and forth on the heat-sealable mylar bags for a maximum of twice, and seal the meal bags. Go for the metallic straighteners instead of the ceramic ones. 

A clothing iron and a metallic hair straightener both can be considered the best heat sealers for mylar bags of 5-gallon capacity. 

• Food Saver

The term “food saver” is the first thing that is most likely to pop into many people’s minds when they think of sealing mylar bags. The reason being that this sealing approach is well-suited for small-sized mylar of gallons and quart bags. 

However, this sealing method is, at times, a bit tricky too. What happens is that often, the sealer seals the mylar bags even before completely vacuuming the whole air out. This makes this heat-sealing method less efficient. But it’s not even that big of a deal when you have oxygen absorbers incorporated in the heat-sealable food bags. Oxygen absorbers are here to your rescue. These are particularly imparted to the mylar bags, just to remove all the unwanted oxygen from the bag. 

Crucial Factors You Must Not Ignore:

• Temperature:

Setting the right temperatures of the sealers is very critical while heat sealing the mylar bags. In case of heat sealing the mylar bags having 7 Mil size, the recommended temperature to set is 375 to 425 F. This is also the same range to set the iron sealers temperature too.

• Seal Width:

Position the mylar bags on the sealing machines carefully. The bag must be placed in such a way that the topmost opening end of the mylar bag runs through the heat-sealing machine, less than 0.25 inches from the top. 

It is recommended to seal the bags above the tear notches to allow easy opening and easy access to the stored edible.
