It sounds like you're having some trouble with air leaking back into your vacuum-sealed bags after removing the sealer. This can be frustrating, but there are a few things you can try to fix it: - Make sure you're getting a good initial seal before taking off the vacuum device. Double check that the bag is fully closed and airtight. When you do remove the sealer, try to do it slowly and carefully. Pull straight up while keeping the bag nice and flat - any wrinkles or folds can let air sneak back in. As soon as the sealer is off, quickly fold or roll up the open end of the bag to keep it sealed. If it has a ziplock, use that, or you can roll it tightly and clip it shut. For extra protection, you could run the sealer over that folded end one more time before putting the food away. It's also worth checking that your sealer itself is in good shape. Make sure the gaskets and sealing strip are clean and not worn out. You might need to replace parts if they're damaged. Also, be sure you're using bags meant for vacuum sealing. Regular zipper bags often won't give you that airtight seal you need.
