The PrimaVac406 vacuum sealer is ideal for large volumes and is capable of packing two 8″ wide pouches at a time. In addition, it can also hold larger containers and jars for additional processing options. The Gas Flush Feature is specifically designed for packaging delicate ingredients, and is available only with the PrimaVac406. By replacing oxygen with inert gas, Gas Flush helps to preserve the color and texture of certain foods and minimizes the potential of crushing fragile contents by creating a pillow effect.
