It should be no stranger to everyone. We all encounter paper tubes in our daily lives. The paper tubes are made from paper, but we will find that the paper tubes are dented when we use them. What is the cause?

1. The box size design of the paper tube is unreasonable

In the case of the same size, the height has a greater influence on the compressive strength of the empty box. When the perimeter of the four sides of the paper tube remains the same, as the height of the paper tube increases, the compressive strength decreases by about 20%.

Two, corrugated deformation

The cardboard that produces corrugated deformation is soft, with low plane strength and low rigidity. Corrugated paper tubes made of such cardboard have low compressive strength and puncture strength. Because the shape of the corrugated board is directly related to the compressive strength of the corrugated board.

Third, the thickness of corrugated cardboard does not meet the requirements

Because the corrugated roller will be worn during use, the thickness of the corrugated cardboard does not meet the specified requirements, so that the compressive strength is low, and the strength will also decrease.

Fourth, the design of the number of cardboard layers is unreasonable

The unreasonable design of the number of cardboard layers will increase 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.
