Which aspects are related to the compressive strength of corrugated boxes

1. the annular compressive strength of the paper is the key to ensure the compressive strength of the carton, but other physical properties of the paper can not be ignored.

When the tensile strength of the paper, especially the corrugated paper, is not enough, the force and deformation of the carton will increase steadily in the compression test, * the final value is very high but the effective value is very low, and the deformation of the carton after the test is like an accordion. www.chinacartonmachine.com

2. the influence of moisture on the compressive strength of cartons can not be ignored.

The waterproof performance of paper and paperboard is also very important. Sometimes, although the compressive strength of cartons is very high, the paper is not waterproof and is prone to moisture, resulting in the collapse of the warehouse.

3. the production process of cartons will also affect the compressive strength.

The production process of cartons will also affect the compressive strength. If the pressing line is too wide, the force value of the carton will increase slowly during the compression test, the effective value will be small, and the final deformation will be large.

4. it is also crucial to select the appropriate ridge type according to the carton type.

In people's consciousness, it is often believed that the larger the ridge, the higher the compressive strength of the carton, and it is easy to ignore the influence of the ridge on the deformation.

5. the carton is composed of paper at all levels. The reasonable allocation of paper is the basic condition to ensure the compressive strength of the carton.
