The bags are textured on one side.I may be grasping at straws here: are your bags textured differently on each side? If so, would you want to try flipping them and seeing if you get different results?
Those chamber sealers are the bomb. My Son picked one up a few years ago on a black friday deal.
Paid $600.00.
Whoaa....My price when I clicked the link was $2500
Anything with moisture I either wrap in plastic wrap (Glad Wrap, Saran Wrap) before sealing...or, if it's small enough, put it in a sandwich bag, fold over the top but don't seal it. Alternatively, freeze your items first, then vac seal it. If you freeze multiple items in one large bag like I do, the plastic wrap/sandwich bags help keep them separate so they don't freeze together to the degree that you can't break them apart.To be honest these vac packing machines are seriously rookie machines all of them....they do an okay job at the best. Not trying to be rude....
Anything with liquid or even just a moist piece of salmon and they pull the moisture out and make a mess.
I tried to vac pack corn off the cob and while I got them all sealed it did pull all the moisture out of the bags.
Says unavailable at the moment but it appears to be a good working machine....the reviews are positive and the pics look great....Amazon.com
