I have just borrowed the foodsaver from my mother-in-law and can only get some of the bags to stay sealed. She had no info for me so I am just winging it. Any one have this down? I have 8 pounds to bag up!!
I always do a double seal with stuff like that, where I might not check in on it for awhile. Seal it once, then immediately move the bag about 1/4"in or out of the mouth of the machine, and make another seal. This works best for me.
I'd say either the sealer is loosing some of it's strength or you're not getting the bags flat enough on the seal strip. I feel very wasteful doing it, but you have to make the bag quite a bit larger then what you are putting in it to allow for it to lay flat in the machine.
