what brand of commercial sealer did you get? i have a food saver that is starting to have a little trouble after 8 years of hard use.WE vacuum seal a lot of things in our household, meats get pre frozen if possible, we butcher our beef and pork ourselves mostly, but will take advantage good sales at the grocery store also. we vacuum seal flour in paper bags inside the vacuum bags. Have been thru a few vacuum sealers then bought a commercial it has lasted 6 years and still going.
