| Sealing Mylar Bags
EARTHQUAKE......inquired if you can seal Mylar bags with your Foodsaver. The answer is YES and NO. If you compare the mylar bags to the foodsaver bags side by side, you will notice the foodsaver bags have "ribs" built into them. These "ribs" form a passage way for the air to escape when the vacuum is being applied. The Mylar bags, on the other hand, are perfectly smooth. If you put a Mylar bag in the Foodsaver, it will "pinch off" the airflow and no vacuum is formed.
You can deal with this in one of two ways, however. First, and most common, is to add Oxygen absorbers then use the heating element of the Foodsaver just to seal the bag...the O2 absorbers will do the rest.
If, on the other hand, you don't want to use the absorbers, you CAN vacuum seal with the foodsaver. Cut off about a one inch strip of ribbed foodsaver bag and put it across the opening of the mylar bag. Be certain that the strip doesn't come in contact with the Foodsaver heating element but DOES cover the lip of the vacuum chamber, then seal as usual. This will keep the airways open, allowing a vacuum to form and the heating element can still seal the Mylar bag. Takes a little practise but very doable.
Hope this helps?
