The strength design of corrugated cardboard boxes involves selecting the appropriate corrugated board construction, box style, and dimensions to meet the required performance criteria for the intended application.
Factors to consider in the strength design of corrugated cardboard boxes include the weight and fragility of the product being shipped, the mode of transportation, and the expected handling and storage conditions.
To determine the appropriate corrugated board construction, various tests such as edge crush test (ECT) and bursting strength test (BST) are conducted to measure the compressive strength and puncture resistance of the corrugated board. Based on the test results, the appropriate board construction can be selected to ensure that the box can withstand the required amount of pressure and impact during transportation and storage.
The box style and dimensions also play a critical role in the strength design. For example, a box with a larger surface area or a taller height may require a stronger board construction to prevent crushing or collapsing. Additionally, the use of reinforcements such as inner packing materials or external strapping can further enhance the strength of the box.
Overall, the strength design of corrugated cardboard boxes is a critical aspect of ensuring that products are safely transported and stored.
