What factors can affect the bursting strength of paper and corrugated boxes?

The bursting strength of cartons and corrugated boxes is affected by the following factors:

1. Material quality: The material quality of cartons and corrugated boxes is one of the main factors affecting their bursting strength. High-quality cardboard and corrugated cardboard can provide stronger structural support and compression resistance, thus increasing the bursting strength of the carton.

2. Corrugated Chip Thickness: The bursting strength of a corrugated carton is also affected by the thickness of the corrugated chips. Thicker corrugated chips provide greater compression resistance and support properties, thus increasing the bursting strength of the carton.

3. Corrugated Chip Type: Different types of corrugated chips have different compression resistance properties. For example, BC corrugated chips (thick corrugated chips on both sides) have higher compression resistance than B corrugated chips (thick corrugated chips on one side) and therefore have a higher bursting strength.

4. Cardboard plies: The bursting strength of cartons and corrugated boxes is usually influenced by the number of cardboard plies. More layers of cardboard usually means more structural and compression resistance, which improves the bursting strength of the carton.

5. Structural design: The structural design of a carton also has an effect on its burst strength. Reasonable structural design can provide better support and compression resistance, which improves the bursting strength of the carton.

To summarize, the bursting strength of cartons and corrugated boxes is affected by a combination of factors such as material quality, corrugated chip thickness, corrugated chip type, number of cardboard layers and structural design. When designing and selecting cartons, these factors should be considered comprehensively to ensure that the cartons have sufficient bursting strength to meet the actual needs during transportation and storage.
