Simple plastic packaging bag vacuum sealing device
By incorporating a horizontal plate and a guide hole within the sealing gasket, the problem of low air extraction efficiency caused by the compression of the packaging bag opening is solved, achieving a vacuum sealing effect that provides rapid air extraction and stable sealing.

AI Technical Summary
In existing technologies, when packaging bags are vacuum sealed, the opening is squeezed by the sealing gasket, which reduces the air extraction efficiency and makes it impossible to quickly extract the air from the packaging bag.
A horizontal plate is installed inside the annular sealing gasket for quick extraction of gas from the packaging bag through the guide hole, and the snap-fit assembly is used to keep the sealing gasket stable and pressurized, thereby improving the extraction efficiency.
This technology enables rapid extraction of gas from the bag even when the sealing gasket squeezes the opening of the packaging bag, thus improving the efficiency of vacuum sealing.
