Looking for big cardboard boxes? The K40, double walled boxes are seriously stiff and strong with a Box Compression Test Strength (BCT) of 3270N. This box is over 2.5 times stronger than the Industry Standard in the material strength Box Compression Test. In comparison, a standard single wall box will have a material strength of between 1190 and 1270N. (The Box Compression Test shows the force required to crush a box with a size of 400x300x200mm.)

Perfect double walled boxes fitting large, general household appliances such as mini fridges, sandpits, children's play tables and other equipment.
