Q&A-Why can’t the vacuum effect be maintained after using the vacuum sealer?

Why can’t the vacuum effect be maintained after using the vacuum sealer?

The following are possible reasons. Users can check by themselves first.

1. The wrong material of packing bags: the material of plastic bags is PE, PP which can’t maintain the vacuum effect. The air will enter into the bags after the vacuum sealer finishing working. It is recommended to choose Nylon bags, Aluminum foil bags which can maintain the vacuum effect for a long time.

2. The sealing line is not sealed well: please check whether the sealing line is complete or not. If the sealing line is not closed, the air will run into the bags.

(1) If the bag is too thick, and the vacuum sealer wasn't set for enough sealing time, the heat wasn't enough to seal the bag. If the vacuum sealer can adjust the sealing time, users can add more seconds to test whether the sealing is firm. If the vacuum sealer can't adjust the sealing time, users may need to replace the thinner bag or buy another vacuum sealer with setting sealing time function.

(2) There have also been cases where the bottom seal of the original bag was not sealed properly. In this case, seal the bottom sealing line again before vacuuming.

3.     Vacuum bag styles are not suitable for vacuum sealers: non-nozzle vacuum sealers can't be used for vacuum flat bags. Therefore, if you buy a non-nozzle vacuum sealer, you must pay attention to the style of the bag you use. This vacuum sealer is a must-to-use vacuum embossed bag or Nylon gusset vacuum bag. It is recommended that when purchasing a vacuum sealing machine or vacuum bag, it is more appropriate to confirm with the supplier first.

4.     The vacuum bag is broken:

(1) If the package article has acute angles, be careful not to cut the vacuum bag when putting it into the vacuum bag.

(2) Vacuum sealer in the process of pumping, when the bag is shrunk to the package, it may be punctured by the packaging.
