1 Quart 7-Mil Gusseted Zip Lock Mylar Bag plus 300 CC Oxygen Absorbers

This is by far my favorite Mylar bag for my freeze drying.  I like that I can open up the bag and expand the gusset.  This allows the bag to stand up while I fill it.  Then I can zip it shut with the zip lock and set it aside.  Once I have all the bags filled, I can cut open my oxygen absorber bag, pull out the number of packets I need and reseal the packet bag.  Then I can open the zip lock on each Mylar bag and drop in an absorber, press out the excess air and close the zip lock again.  Once all the bags have absorbers in them, I can use the impulse sealer to seal each one.  The zip lock allows me to keep moisture out while I work through the filling process and the gussets help keep the bags from falling over and spilling the contents.  It's also easier to seal the bag with the zip lock closed.  The zip lock holds the top of the bag together for an easy seal.  These are the only bags for me!
