    Double Chamber Vacuum Sealer

    The working principle of this machine is quite simple. Put the bag or pouch which needs to be sealed inside the chamber. The chamber cover of the machine can either be closed manually or automatically. Next, the machine sucks out almost all of the air inside it, making its environment vacuum like. Then the machine seals the bag, making it airtight.

    After this, the bag is ready to get shipped. The environment inside the machine is changed back to normal. Sometimes the air inside the machine is replaced by inert gas like nitrogen to make the atmosphere non-reactive with the bag inside.

    Single Chamber Vacuum Sealer

    The working principle of single chamber vacuum sealer is almost exactly like double chamber vacuum sealer. The bag or pouch is placed inside the single chamber. The lid is closed manually. Next, the machine takes out all of the air inside it and the bag is sealed where it is open. After this, the airtight bag is taken out and is ready for shipping.

    Even though the process of both the sealers is same, however there are a few differences. Firstly, the sealing capacity of double chamber vacuum sealer is more than the single chamber vacuum sealer since it contains more chamber, plus has greater capacity and storage to seal large sized products. Secondly the process of double chamber vacuum sealer is way quicker and more efficient than the latter because it has the capability to perform automated process.
