We are a professional manufacturer of one-way exhaust valves, which are strictly controlled by design, manufacturing, testing and quality.
In order to manufacture a good quality exhaust valve that truly has a one-way exhaust function, we have invested considerable effort and time to continuously study exhaust and seal testing. The function of the one-way exhaust valve is to discharge the carbon dioxide gas in the bag, maintain the appropriate pressure in the bag, and prevent the external oxygen from entering, so that the oxidation rate of the product in the bag is too fast and the retention time of freshness is too short.
We are more active in launching the "filter-type one-way exhaust valve" This filter can filter fine powder, suitable for coffee powder, but also suitable for very fine powder.
If you have trouble packaging exhaust, welcome to contact us. We are the Packaging exhaust solution expert, and will be your packaging exhaust partner.
