Here is some knowledge about corrugated cardboard and corrugated boxes

How to choose the type of corrugated board?

Here's how to choose the type of corrugated board

The types of corrugated board are generally divided into single-sided corrugated board, three-layer corrugated board, five-layer corrugated board and seven-layer corrugated board. Seven-layer corrugated board, also called three-layer corrugated board, is made by pasting three layers of corrugated board between the face paper, core paper and inner paper.

In Europe and the United States, the production of corrugated cartons has fully entered quantitative analysis, and the cost of cartons has been reduced to the limit. Single tile consumption of corrugated cartons accounts for about 90%, and double tile consumption accounts for about 10%. This requires corrugated carton manufacturers to actively guide their customers and choose corrugated cardboard wisely to avoid excessive packaging and unnecessary waste of resources.


What are the considerations for corrugated carton size design?

As a mainstream packaging container, corrugated boxes have always been a focus of attention for users and manufacturers. But when it comes to practice, the little details are enough to "beat" these principles.

In fact, the principles of corrugated carton design can be summarized as "protection requirements." Protection requirements refer to the design of corrugated cartons to meet the protection function of the products.

Corrugated boxes usually have three dimensions: external dimensions, manufacturing dimensions and internal dimensions. First, after the corrugated cardboard is folded 90 degrees, for the internal and external offset of the dimensions, the position of the pressure line is different and is not exactly half the thickness of the corrugated cardboard. Second, due to the size difference between the internal and external offset of the corrugated cardboard, when the internal and external dimensions and manufacturing dimensions are converted, the expansion and contraction volumes of the standard box (RSC) are different The external dimensions, manufacturing dimensions and internal dimensions of corrugated boxes are interrelated. Dimensional design is a key factor, so it is very important to understand the factors that influence dimensional design.

We hope the above explanation is helpful. If you need custom corrugated cartons or other packaging cartons, you can contact our manufacturer.
