Mylar food storage bags are an integral component of any good food storage systems and has been used for many years. Food grade metalized mylar bags are used for lining food storage pails. Mylar bags create an oxygen barrier to protect food during extended long-term food storage. Mylar bags for food storage can be sealed with a standard heat sealing unit or with an ordinary clothes iron. All of our bags are designed to be heat sealed including our ziplock bags and stand-up pouch bags which are great for getting into and out of the bags more frequently. We have specifically designed our ziplock bags so that there is still room above the ziplock to heat seal them for long-term storage.
All of our mylar bags are a minimum of 5.0 mils thick (compare to other manufacturers at 3.5-4.3mils), for better long-term storage of emergency supplies with an FDA approved sealant layer. Important Note: All of our mylar bags have a complete middle aluminum foil layer (.00035) and are NOT simply metalized polyester that other manufacturers produce. If you can see through the bag it is not aluminum foil and the food can be affected by light and oxygen, which are major reasons for using mylar bags.
