Strong cardboard boxes made from double wall cardboard. Internal dimensions: 229 x 152 x 152 mm (9 x 6 x 6 inches). Pack Of 20. These cartons have the added advantage of being multiscored at 102mm. This allows you to reduce the depth of your carton to a pre-scored dimension, by cutting down the existing slots (between the flaps) and folding along the pre-scored crease. Double wall cardboard boxes are manufactured from two sheets of corrugated cardboard which are securely glued together. The extra layer of corrugated cardboard cushions any impact whilst keeping the box intact. These boxes offer superior strength and reliability to customers interested in shipping or storing heavy loads, and when stacking is required. Supplied flat packed - make them up by taping the flaps. Standard brown cardboard colour inside and outside. For clients looking to purchase in bulk, we offer affordable wholesale pricing and discounts.
