These durable Mylar Pro EXTREME Zip-Lock Foil Barrier Bags are quite simply THE VERY BEST MYLAR BAG ON THE MARKET. Not only do they come with 5.25 mils of the Exclusive Mylar PRO material, but they also have a very convenient zip-lock feature built right into the bag. In other words, you can heat seal the top of the bag just like you would heat seal other Mylar bags for long term storage, BUT… when you are ready to open them up to use the food later on, you will be able to conveniently zip-lock seal the remaining contents so that it will continue to stay fresh even longer.
These zip-lock Mylar PRO Bags can also be used for just short term use too. With this method, you can avoid heat sealing them and just simply zip-lock seal them instead and it will keep your short term food fresher longer. (NOTE: the zip-lock method won’t keep a true vacuum seal for very long. Because since the oxygen molecules are so tiny, they will still be able to gradually permeate the manual zip lock seal. Hence, this is more a short term solution. Therefore, if you are looking for a “long term” solution, you will want to heat seal them for that.)
NOTE: When heat sealing, just seal the top 1/2 inch of the bag (making sure you do not get too close to the zip lock part). This way, you will then be able to re-use these bags several times, by just trimming off the top heat sealed portion of the bag with scissors each time.
