Method of making carton pressing line

After the board is cut, mark the size recorded on the paper on the board. According to the size recorded by us, measure the corresponding size on the cardboard with a tape measure, and mark with a pen. After marking, the next step is to mark the line. Use a straight edge to align the two corresponding points on both sides of the cardboard so that they are in the same straight line. Use an art knife to gently stroke the cardboard along the straight edge. In the process of drawing, the straight edge should be pressed tightly, and it should not be moved, so as to avoid not straight drawing. Pay attention to use light force, just use the tip of the knife to scratch the cardboard skin, and see the traces, and do not draw too deep to avoid cutting the cardboard: after all the pressing lines are finished, Use the handle part of the knife to deepen the pressing line along the scratch, so it is easier to fold up the cardboard. The pressing line is finished. Next, cut off the ears of the opening part at both ends of the cardboard box. Use the art knife to cut back the ears of the two long sides along the pressing line (when cutting to the pressing line of the long side, cut off about 5mm on both sides of the ears at the same time, so that both ends are sealed It will not be opened later, and the packing will be closer. The ears at both ends of the 5cm joint part left on the short side can be removed, which is useless. At the same time, the middle part can be cut into ladder shape with a knife. At this point, the carton line pressing part is completed.
