Corrugated cardboard is very strong. Corrugated cardboard is the material used to make most cardboard boxes, providing excellent protection for their contents. It consists of two layers of flat paper with a layer of fluted paper between them. This structure gives it great mechanical strength, making it ideal for manufacturing cardboard boxes. And on top of that, it is recyclable and sustainably manufactured.
These properties are known by manufacturers of all types of products that use them for the protection, preservation, transport and/or presentation of them. In a “simple” cardboard box a large number of properties converge that make it unique.
And this, as we said, the manufacturers know, too even the dog knows about the video he's asking for in the shops cardboard boxes because he knows that on top of a box he will sleep much more comfortable and warm than on the floor. And the dogs are very smart.
