Paper Tube
It should be familiar to everyone. We all encounter paper tubes in our daily life. The paper tubes are made of paper, but when we use them, we will find that the paper tubes are dented. What is the cause?

1. The size design of the box of the paper tube is unreasonable
When the dimensions are the same, the height has a greater impact on the compressive strength of the empty box. Under the condition that the perimeter of the four sides of the paper tube remains unchanged, with the increase of the height of the paper tube, the compressive strength decreases by about 20%.

 

2. Corrugated deformation
The corrugated cardboard itself is soft, with low plane strength and low rigidity. The compressive strength and puncture strength of corrugated cardboard tubes made of such cardboard are also small. Because the shape of the corrugated is directly related to the compressive strength of the corrugated cardboard.

 

3. The thickness of corrugated cardboard does not meet the requirements
Since the corrugated roller will be worn during use, the thickness of the corrugated cardboard cannot meet the specified requirements, resulting in a low compressive strength and a decrease in strength.

 

4. The design of the number of cardboard layers is unreasonable
The unreasonable design of the number of cardboard layers will lead to an increase in the breakage rate of the outer packaging paper tube. Therefore, the number of cardboard layers used should be considered according to the weight, nature, stacking height, storage and transportation conditions, storage time and other factors of the packaged goods.
