The household vacuum machine just bought and the ordinary vacuum bag bought can only be sealed without air extraction. What kind of bag can be used!
vacuum packaging machine must use vacuum packaging bag. Vacuum packaging bag is not an ordinary plastic bag. It is made of PE and nylon, so it has better quality and is not easy to leak.
is it possible that your bag is the problem? Because the bag of vacuum packaging machine is of composite film. If you have a single-layer film, it may stick to the bag.
