The thickness of ordinary three-layer corrugated box packaging is generally about 3.5mm, and the thickness of five layers is about 7mm. Therefore, before choosing cartons, we need to measure the length, width and height of the package, and then add the thickness of the box. The combination is the size of the carton. What most manufacturers say is actually the size of the outer box.

When designing the size of the carton, in order to save raw materials, the width of the carton will be reduced as much as possible. Therefore, when customizing cartons, it is very important to explain to the manufacturer whether the size provided is the outer box size or the inner box size.

According to the weight and cost of goods, the packaging materials of cartons should be reasonably selected. Cartons are made of cardboard. Corrugated cardboard is commonly used in our daily life. Corrugated board can be divided into face paper, corrugated paper, core paper, inner paper, etc. The material of cardboard is mainly related to the weight per square meter. The heavier the weight per square meter, the better the quality of the paperboard. The paper of ordinary cartons is distinguished from the smoothness of appearance and the hardness of touch.

Generally, the larger the printing area of carton packaging, the higher the cost. At the same time, the printing cost of carton packaging is also related to the color type of printing. Once printing starts, it cannot be modified. Therefore, before the official printing, we must confirm the printing content with the customer, or even repeatedly, to ensure the correctness of the printing content. If an unexpected error occurs in the printing process, it can be covered with self-adhesive stickers or warm water stickers with similar appearance colors. The carton packaging problem will have a certain impact on the appearance. Therefore, we should provide accurate printing materials and supervise the manufacturers to strictly print from time to time.
