The bursting strength of a corrugated box is typically measured in pounds per square inch (PSI) or kilogram-force per square centimeter (kgf/cm2). The bursting strength of a corrugated box that contains a 20 kg weight will depend on various factors such as the quality of the corrugated material and the construction of the box. It is recommended to refer to the specific specifications provided by the manufacturer for the bursting strength of the corrugated box.
The bursting strength of a corrugated box is typically calculated using the Mullen Test. The formula for bursting strength is: Bursting Strength (in pounds per square inch) = Bursting Test Value (in pounds) / Area of Sample (in square inches). The bursting test value is determined by a testing machine that applies increasing pressure until the box bursts.
The burst strength of a paper corrugated box is typically calculated by conducting a burst test. The test involves applying pressure to the box until it ruptures, and the pressure at which this occurs is recorded as the burst strength. The burst strength is commonly measured in pounds per square inch (psi) or kilopascals (kPa).
To calculate the PSI (pounds per square inch) of a corrugated box, you would typically divide the total weight the box can hold (in pounds) by the surface area of the box (in square inches) that is carrying that weight. This calculation gives you the pressure exerted on the walls of the box in pounds per square inch.
Use some standard of cardboard wt. per square ft, as a box has six sides, you have (length x width + length x height + width x height) x 2 x lb/ sq ft or if in metric kg/ sq m. Get net weight by subtracting cardboard wt from box wt. One standard cardboard box wt. in US is 0.13 kg/ sq m. This number will vary in US and, may be quite different in other countries.

The ideal bursting strength for a 5-ply corrugated box typically ranges between 200 to 400 psi, depending on its intended use and the weight of the products it will carry. This strength ensures that the box can withstand the rigors of shipping and handling while protecting its contents. Factors such as the type of material, construction quality, and design can also influence the optimal bursting strength for specific applications. Always consider the specific requirements of your product and transport conditions when determining the ideal strength.
Bursting factor times grams per square meeting is the formula for calculating bursting strength of a cardboard box. It shows the pressure required due to weight to cause the breach. The bursting strength is printed on the bottom of the carton.
The ratio of compressive strength to the weight of a corrugated box can vary widely depending on the materials and design used. Typically, compressive strength is measured in pounds per square inch (psi), while the weight is measured in pounds. A higher ratio indicates a more efficient design, where the box can support more weight relative to its own weight, which is desirable for shipping and storage. This ratio is crucial in packaging engineering to optimize performance while minimizing material use.
