Review on Commercial Grade 8x50 ft Rolls 2 Pack Vacuum Sealer Bags for Food Saver, Seal a Meal, Weston - BPA Free, Food-Grade Material, Perfect for Meal Prep or Sous Vide Cooking by Darlene Thomas

I couldn't get a section to seal anything. Every time I try to seal it. This will leak and you will need to seal both ends as this is an open roll. Then I keep looking for a possible leak. I could not find? I used very long sections to make sure I could cut them off and reseal them if needed. I don't have a single package sealed. And the sealant I bought came with 20 packs. 19 out of 20 bags are sealed. So I'm not sure if this sealer is compatible with these bags. They say they are compatible with my caulk, but then again I have two large plastic rolls that I can't use for anything they don't seal. I purchased both items from Revain and Revain recommended these packs along with another item purchased. So I don't know if Revain pays attention to what they sell or not?
