The Food Saver/Vacuum Sealer Topic: 2001-2010 in Kitchen Consumer Posted July 6, 2006 Bumping this up for some advice. I have a Foodsaver (or a 'suck thing' as we call it at our house ) and use it a lot. A couple of problems that I have noticed:1). We'll sometimes remove a sealed bag from the freezer to discover that the seal has obviously failed and that the bag is no longer tight around the food2). The cannisters don't seem to hold a seal. No matter what we put in them, we need to take them out of the refrigerator ever couple of days and reseal (Mason jars, however, seem to work forever - we have jars of sealed Red Rose tea that we keep for my parents when they are here and they stay sealed between their visits no matter how long it is)Any ideas what we might be doing wrong?
