if there is only a slight crack and white paper is exposed, it is recommended to apply it with a color pen to see what the background color of the printing surface is, and find the closest color pen to supplement the color. If you don’t pay attention or the expert can’t see it

  Performance of packaged products :

the performance of packaged products mainly includes the physical state, shape, strength, weight, structure, value and danger of the product, which should be considered first when packaging

banner

① product state. There are mainly solid, liquid, gaseous, mixed and so on. The packaging containers are also different for different physical states

② product appearance. It mainly includes square, cylindrical, polygonal, special-shaped, etc. its packaging shall be designed according to the product appearance characteristics. It is required that the packaging volume is small, well fixed, stable storage and meet the standardization requirements

③ product strength. For products with low strength and vulnerable to damage, the protective performance of the package shall be fully considered, and there shall be obvious marks on the outside of the package

④ product weight. For products with heavy weight, special attention should be paid to the strength of packaging to ensure that they will not be damaged in circulation

⑤ product structure. Different products often have different structures, some are not pressure resistant, some are afraid of impact, etc. Only by fully understanding the product structure can we carry out appropriate packaging for different products

1. The cracking at the crease of the paper is because the indentation is too deep or the width of the indentation is not enough. If the outer side cracks, the pressure of the indentation is too large, the folding is too deep or the paper is brittle
2. After die cutting, the paperboard adheres to the knife plate to increase its brittleness; The thickness of copper wire pad is insufficient, and the pad is too low or too high; Increase the thickness of steel wire pad paper. The reason is that the indentation groove on the copper wire pad is too wide
3. In terms of repair, if only emergency tape can be used, if there is a pattern on the outside of the box stained 502, the stain cannot be removed. If there is only a slight crack and the white paper is exposed, it is recommended to apply it with a color pen to see what the background color of the printing surface is, and find the closest color pen to supplement the color. If you don’t pay attention or the expert can’t see it.

the water chestnut of the carton will crack due to many factors, such as box type design, box pressure tolerance, knife die design, etc

in the design of the die, we should consider the corrugated material. It is necessary to design the water chestnut into right angles or rounded corners. Sometimes the line is too shallow at the time of die-cutting, so that it is difficult to form and burst

in terms of repair, if it is only emergency tape, it can be used

in terms of repair, if it is only emergency 502 and adhesive tape, it can be used. However, 502 is fast dry but fragile. If there are patterns on the outside of the box stained with 502, the stains cannot be removed

502 is corrosive. If you don’t do it well, it will cause problems

you can stick it down with transparent tape or use hard paper card to lay it inside and stick it with ordinary glue

I agree with “harmonica loner – level 7” His statement

if the cracking is not serious, you can stick it with wide transparent tape. 5kg multiple sealing is not a problem

but I want to know what the box contains. It’s a gift or a packing box. It doesn’t look good how to stick the gift
