How much weight can cardboard carry?

The weight that cardboard can carry depends on various factors, including its thickness, type, and how it's constructed (single-layer vs. multi-layer). Generally, a standard corrugated cardboard box can support anywhere from 30 to 100 pounds, with heavier-duty options capable of carrying even more. However, it's essential to distribute the weight evenly and avoid exceeding the box's recommended load capacity to prevent collapse. For specific applications, testing or consulting manufacturer guidelines is advisable.
