Allegedly, just connect the household vacuum cleaner and put the upper part of the plastic bag containing the aquatic product in the packaging device. That is to say, the air can be taken out to complete the packaging. With this wrapper, different sizes of aquatic products can be vacuum packed, suitable for small-scale aquatic product processing and department use.
