The cutting matter of the paper-like paper is slightly different from the film material. Although in theory, PE protective film manufacturers must cut through the face material and the adhesive together, the theoretical die-cut paper material is the combined result of tool cutting and paper breaking, that is, the cutting edge of the blade is cut. The paper is also pressed to both sides, so that the die-cutting precision of the paper-like material is not very high. When analyzing samples, it is often seen that some labels have burrs, which is due to the fact that the material fibers are coarse and naturally fractured.
Based on the die-cutting characteristics of paper-based materials, and considering the wear of the blade, the angle of the flat-film cutting blade of the PE protective film manufacturer is 52°. The assumed angle is large, and the extrusion deformation of the material is large, that is, the horizontal tendency The discriminating power will make the material breakage distinction.
Die-cutting of film-based materials, PE protective film manufacturers simply say the process of complete cutting. Because most of the film materials have toughness and do not break naturally, it is not suitable to cut through two-thirds. It is necessary to completely cut through or cut through four-fifths of the thickness, otherwise it will be peeled off together with the label.www.snpefilm.com
