How much weight can a large cardboard box hold?

Generally, our heavy duty cardboard boxes are engineered to hold 10-20 kilograms safely, making them ideal for a wide range of uses. Secured with packing tape, and used in conjunction with moving blankets for extra cushioning, recycled bubble wrap, or bubble wrap alternatives for delicate items, our boxes offer maximum protection for your belongings.
