Well this depends on you imagination.
The with of our Slimbox is 100 cm. The length is ... well... endless. (you can buy flatboard cardboard with a length of 400 cm). If you feed our Slimbox with a cardboard of 100x150 cm, we can cut a box with dimensions of 35 cm x 35 cm x 60cm.
But we developed a technique that makes it possible to combine different cardboard... And then, the possibilities are endless.
The maximum size of the corrugated cardboard that you can enter in the machine can be found here.
