Maximizing both the transport cubic efficiency and space savings at destination, 4 Foldia® roll containers can be stacked inside an open one. This makes it the most space-efficient roll cage of our portfolio. Because Foldia® is compatible with demountable or other folding roll containers, your existing fleet of carts can be upgraded step by step. As with all K. Hartwall products, Foldia® stands for efficient reverse logistics and long life-span for a low total cost of ownership. Foldia® also complies with ISO standards.
