The applications of corrugated paper in our lives are as follows:

Analyzing the change in the shape of an object can change its ability to resist bending, paper packing boxes using corrugated cardboard, in fact, are to reduce the width of the material and increase the thickness of the material, which greatly enhances the resistance to bending. Corrugated cardboard in our lives are used in cardboard boxes, paper cups, cup sets and so on.

The answer is: cardboard boxes; paper cups; cups.

Corrugated cardboard is made of hanging paper and corrugated cardboard through the corrugated stick processing and the formation of corrugated cardboard bonded from the plate, we found that the original can be simply stacked by the wave, so that the paper shows such a "tough" qualities, it is really impressive.

Corrugated paper is also widely used in life because of its low cost, light weight, easy processing, high strength, easy storage and handling, and easy recycling.

There are many types of corrugated cardboard, and their overall forms are similar to each other. There are two common types, which are generally divided into two categories: single-corrugated board and double-corrugated board. These are commonly referred to as "2+1" and "3+2" structures.

We found that the corrugated cardboard sandwiched between the two sheets of paper has been transformed from "straight" to "corrugated," reducing its width, increasing its thickness, and increasing its ability to resist bending. (Note: The corrugated paper sandwiched between two sheets of laminating paper is called corrugated paper, and the whole is also called corrugated paper).
