Corrugated paper is often used in Shenzhen packaging printing. It is also currently the most mainstream packaging material. However, if the package has a dimensional deviation, it is equivalent to a fatal mistake. Before the packaging and printing in Shenzhen, the size must be communicated with the customer, and only the appropriate customer will accept the use. The size is not right, no matter how good the other projects are, it will not help. However, to really manage and control the size of the packaging is very systematic.

The size of Shenzhen packaging printing has three forms: inner size and outer size manufacturing size. In the process of corrugated paper packaging, the thicker the cardboard, the larger the expansion value, the wider the pressure line, and the larger the expansion value. In other words, the corrugated cardboard should be crimped to make the corrugated cardboard bend well. At the same time, the corrugated cardboard will be damaged by crimping, which will cause the inner paper to shrink and the face paper to extend. The amount of expansion and contraction is directly related to the thickness of the cardboard and the way of pressing.

In fact, the biggest purpose of packaging printing in Shenzhen, in addition to its beautiful appearance, should also have the property of protecting the contents. Usually, the outer swing cover must be docked and sealed. In principle, the theoretical value of the width manufacturing size should be one half of the box width manufacturing size. This requires that the size of the package must be calculated accurately, and neither the lid can be stacked, nor can there be a gap after docking. Therefore, it is very important to calculate the correction value of the manufacturing dimension of the outer flap width. Because the cover is on the same pressure line, the inner swing cover is folded to produce a supporting effect on the outer swing cover, so the outer swing cover must create a certain gap at the joint. This correction is generally half the thickness of the lined cardboard. Therefore, it is best to determine by actual measurement.

Only in this way can Shenzhen packaging printing embody the practical value to the maximum. It is on this basis that we can take into account both aesthetics and creative design, and take advantage of Shenzhen packaging and printing. In the design of the packaging and printing structure in Shenzhen, it is determined according to the types and properties of corrugated cardboard and interior goods used in different corrugated types of manufacturing equipment and different production processes. Only in this way can we make packaging that protects and beautifies the goods.
