In the roller film pressing operation, when the roller rolls the film from the stepped geometric area between the plate body and the stepped part to the outer surface of the stepped part, the gas in the dead angle space of the stepped geometric area can be discharged into the gas containing hole at the adjacent position by the extrusion action of the roller, wherein before the film does not completely seal the gas containing hole, the gas containing hole is utilized to provide a gas escaping path, so that part of the gas in the dead angle space can be discharged from the outer surface of the stepped part through the gas containing hole until the film completely seals the opening of the gas containing hole at the outer surface position of the stepped part, under the action of the roller extrusion film, the other part of the gas in the dead angle area can be concentrated in the dead angle space between the side end surface of the stepped part and the unit surface which are communicated with the dead angle area in Rong Qikong, thus, the film can be smoothly attached to the plate and the stepped geometric area thereof, a more complete film attaching effect is achieved, and defects of bubbles generated by gas residues on the surface of the plate can be effectively avoided.
