Our double walled cardboard boxes (440x340x140mm) are designed to carry larger, heavier items and loads. This is made possible by our 440x340x140mm heavy duty cardboard boxes being made from two layers of corrugated cardboard which are securely glued together to offer much more protection. If you need to ship large items and want maximum protection during transit then double walled cardboard boxes are what you need.
We not only supply double walled cardboard boxes but we can also supply single walled cardboard boxes. Single wall boxes are not as strong as double wall boxes but they are just as reliable and of a high quality. View our range of single wall cardboard boxes here.
