How are they constructed - Unlike our other heavy-duty boxes, the double wall shipping boxes feature two sheets of corrugated cardboard which are securely glued together. This advanced construction design provides increased resistance to compression forces during shipping, ensuring that your box won’t be crushed or damaged during transport. These reinforced products can also be stacked without worrying about collapse or harm. Our double walled boxes are the perfect choice for clients interested in shipping or transporting their products throughout the UK.

What are they used for - Double wall boxes are one of the most popular types of carton for shipping goods via a carrier or postal network.  These strong boxes are ideal for heavy objects, and when stacking is required. They also offer extra protection when shipping sensitive products, as the extra layer of corrugated cushions any impact whilst keeping the box intact.

Measuring - Box dimensions refer to the internal (usable) dimensions and are always measured in the same order.  Depending on the board grade and flute, the internal and external dimensions of a box can differ significantly so bear this in mind when working out what size box you need for your item.
