A production process of a sheet label

Abstract

The invention discloses a production process for a sheet-shaped label. The production process comprises the following steps: (1) shearing: shearing release backing paper into a sheet-shaped structure;(2) film lamination: laminating a PP film onto each sheet of release backing paper; (3) cut-shaping of the release backing paper: placing a film-laminated release backing paper sheet into a positioning-hole cut-molding seat, and subjecting the surface of the release backing paper sheet to positioning-hole cut-molding; (4) PP film cut-molding: rotating a positioning-hole cut-molded surface material for 180 degrees, placing the surface material into a surface material cut-molding seat, and subjecting the PP film to shape cut-molding; (5) discharging of waste materials: discharging a waste surface material through a manner of manual peeling, wherein a positioning-hole waste material cut off from the release backing paper is taken away during discharging of the waste surface material by utilizing the adhesion force of the waste surface material; and (6) material collection: after the waste materials are discharged, stacking and collecting the obtained surface material. Through changing ofa cut-molding process, and by adoption of a separate cut-molding manner of the front and back surfaces of the surface material, the positioning-hole waste material cut off from the release backing paper is taken away together with a peeled PP film waste material during discharging of waste materials, so the quality of cut-molding can be guaranteed, and waste discharging is convenient.

Description

technical field [0001] The invention relates to a production process of a sheet label, belonging to the technical field of label production. Background technique [0002] For sheet-like labels, due to the need to cut positioning holes on the surface, the existing production process is usually to complete the PP film cutting type and the positioning hole cutting type in the same cutting seat, by cutting the PP film in half , cut off the positioning hole completely, and then carry out the corresponding waste treatment. However, this type of chopping method requires two manual waste removals on the surface material. First, the waste of the PP film needs to be discharged, and second, the waste of the cut PP film and release liner paper in the positioning hole needs to be discharged. Moreover, the aperture of the positioning hole is small, and sometimes it is necessary to use certain tools to discharge waste. Not only the labor cost of waste discharge is high, but also when usin...

Problems solved by technology

However, this type of chopping method requires two manual waste removals on the surface material. First, the waste of the PP film needs to be discharged, and second, the waste of the cut PP film and release liner paper in the positioning hole needs to be discharged. Moreover, the aperture of the positioning hole is small, and sometimes it is necessary to use certain tools to discharge waste. Not only the labor cost of waste discharge is high, but also when using tools to discharge waste, it is easy to cause scratches on the product and affect product quality.

Moreover, when cutting, the positioning hole waste will stick to the small hole knife, and plugging will occur, which will affect the cutting pressure. The distance between the positioning hole and the label is relatively close. When the positioning hole is cut completely, the PP film is cut in half. , the full-break pressure affects the half-break pressure, and it is not easy to debug
