Dalian packing case

With the continuous development of Dalian packaging technology, the performance of flexible packaging has been improved. The liquid packaging as an example, a valve cap is connected and arranged in an opening, in opening the package, you can make the lid twist off, inside the packaging Straw press the lid, the internal liquid has been squeezed out. Compared with the traditional dumping packaging, the way of squeezing the liquid is more easy to control the amount of use, consumers can use each time on demand, to avoid waste. In multi-color printing, colored ink overprint if the control is not good, it will make the printing color change, resulting in printing quality problems. Therefore, we must analyze and study the situation of ink overprint. In the actual printing production, printing overprint bad defects is white.
