The necessity of magnets, I believe that many people who have seen double-opening boxes or some high-end packaging boxes custom design drawings will find that most of them will have magnets as accessories. Of course, the heaven and earth cover and the side cover are an exception. So why are magnets widely used in these high-end packaging cartons? In fact, it is very simple. The double-opened packaging gift boxes have one thing in common. It is very, very difficult to keep the box in the closed state, because the double-opening feature will make the contact area of the box different from that of ordinary paper boxes. Even if the outer box is lifted vertically, the inner box will not fall out. To ensure that when using, the double-opening box will be relatively wide when it is opened, and it will bring a difficulty that is difficult to overcome by the box itself, and the double-opening box will not close tightly.
In this case, the easiest way to prevent the double-opening box from being easily opened is to install a magnet on the cover box. The techniques generally used are more sophisticated and precise, for example, adjusting the beer boards so that several beer boards are very accurate, and the above situation will not occur, but this is very difficult, and it not only requires the beer board master to be very professional , In order to adjust to a perfect data state, a lot of materials need to be wasted. Think about it, a beer board with a general size will charge 200~300, and a larger size will be more than 300. This high-end double-open box beer board Usually not small.
