Abstract
A packaging material of the corrugated cardboard type includes a laminate of at least one plane paper layer (1) and at least one auxiliary paper layer (3) with waves presenting an amplitude perpendicular to the plane of propagation of the auxiliary paper layer. The two layers are joined by means of a gluing material. The auxiliary paper layer (3) includes furthermore a system of substantially parallel waves (10, 10', 10''), the amplitude of which is in the plane of propagation of the auxiliary paper layer (3). As a result, the packaging material is more stiff than hitherto known without the lightness and voluminocity of the material being affected. In addition, the material possesses an increased tear resistance and is very suited for being provided with prints.
