Paper box production process

Paper box production process 1: Paper box processing. Paper containers are cardboard containers used for packaging goods, such as cardboard boxes, cups, etc. Quality evaluation ships not only evaluate the printing quality, but also simplify the evaluation and processing of container shapes. Paper container manufacturing process: carving and printing → surface processing → cutting, indentation → system box. Materials are generally used for good printing work. For packaging goods, yellow cardboard, kraft paper, cardboard, and white paper are used as substrates, with high requirements. Copper plates can be used to press paper on top of these materials. Printing ink should be light, wear-resistant, oil resistant, and non-toxic according to drug packaging items. Engraving and printing use letterpress, offset printing, gravure printing, and flexographic printing. Nowadays, based on lithography, letterpress printing can achieve good printing results, bright colors, and good product luster, but the plate making process is cumbersome and not as simple as lithography. Dust removal during printing to prevent back offset. 3. The surface treatment can be applied with polyethylene, pasted with surface facial mask, foil, wax, pressure, embossing and other technologies as required, but not all products have undergone surface treatment. 4. Mold (die cutting), indentation (indentation) (1) A better practice for template templates is to use plywood templates. The first level mode is transferred to the plywood box with a wire saw along the tangent and tangent lines, and then the die-cutting and crease lines are embedded into the plywood knife, which is made from the template and has the characteristics of lightweight and precise size, which can save advantages. It can also be used for computer control, laser cutting system version, carton size, shape, and weight. The cardboard enters the computer, and then the computer controls the laser movement to cut all tangent and folded cardboard boxes on the plywood, and finally inserts the knife line. The process is as follows: Draw a horizontal box comp image → Draw a collage without copying the chart → Transfer the makeup design drawings to plywood and saw cut drilling → → Produce a mold female template. ① Draw a paper tray image and a black and white draft cutterhead line diagram. Each box has an accurate size and requires very precise lines, as shown in Figure 8-31. ② The maximum paper size of the makeup design drawing box tray can be printed, and the makeup design should consider saving paper and making it easy to automatically remove waste paper. Design, draw, and assemble designs. ③ Copy the makeup design by copying two makeup designs, one for the printing system and one for template production to ensure consistency and accurate registration when you die. ④ Handdrawn or copied makeup designs that can be transferred to plywood. Hand drawn to ensure high accuracy. ⑤ Special saws are used for drilling and cutting. The sewing machine moves the wire saw up and down. In the two core boxes shown in Figure 8-31, the paper tray copies the images connected to the drilled holes, making it easy to thread and saw along the tangent and crease lines. The thickness of the wire saw blade should be the crease line, and the thickness of the tangent blade should be suitable. ⑥ Tielei machine and guillotine, bending line, punching machine
