How To Improve The Compression Strength Of Carton Boxes

The fundamental purpose of a corrugated box is to sustain the product in its original condition throughout the distribution cycle. In fulfilling this objective, its compression strength plays a significant role. If you’ve heard about a box compression tester, then it goes without mentioning that manufacturers rely greatly on this equipment to test the compression strength of the box. Many of them have also confirmed that after investing in packaging testing machines, especially compression testers, they are able to offer better quality to their customers, resulting in an improved reputation. 

Besides, they also make efforts to improve the compression strength factor. What are those? Let’s find out.

Factors to Improve The Compression Strength Of Carton Boxes

1. Designing The Carton Proportions Carefully

Researchers say that the box proportions or circumference in particular are often directly proportional to its compression strength. The longer the circumference, the higher the compression strength is. Also, the length-to-width ratio of the box should also not exceed 2, in order to maintain a good compression strength. 

2. Calculating The Stacking Time & Technique Strategically

Secondly, the stacking time and method also play a significant role in improving the compression factor. With an increase in the stacking time, there is a decrease in the compression strength. The longer the load span is, the more there is a drop in the strength of the box. Hence, this factor must also be carefully considered while designing the box. 

Besides, the direction in which the box is stacked is also crucial. In the vertical direction, the pressure is more than it is in the horizontal direction. Hence, the box must be designed keeping the maximum vertical pressure in consideration.  

3. Planning The Box Opening Carefully

Some corrugated boxes contain holes to allow for ventilation. Tests show that if these holes or openings are large, then they can negatively impact the compression strength of the box. Also, if they are closer to the top or bottom and farther from the sides, the strength can again lower. 

It is due to this reason that manufacturers stick a layer of reinforcement cards on these holes/openings. This not only impacts the compression length but also safeguards the handle from getting damaged when it is pulled. 

Bottom Line

So above we saw how manufacturers can improve the compression strength of the corrugated boxes. Using these techniques, manufacturers can even improve the impact strength of the boxes, which is tested using a high-quality impact tester.
