After the top film is heated and softened, vacuum is applied to the cavity between the film and the bottom box, and then the top film moves downward due to the pressure difference between the top and bottom sides and gradually adheres to the freshness to fit its contour, relying on the molten gel on the surface of the film to adhere to the surface of the bottom box.
