Corrugated cardboard packaging material

[Abstract] A corrugated board type packaging material comprising a laminated sheet comprising at least one layer of planar paper layers (1) and at least one layer of corrugated auxiliary paper layers (3), said corrugations being perpendicular to the The amplitude of the extended plane of the auxiliary paper layer, wherein the two layers are bonded together by means of an adhesive material. The auxiliary paper layer (3) additionally comprises a system of substantially parallel corrugations (10, 10', 10"), the amplitude of which is in the plane of extension of the auxiliary paper layer (3). As a result, the packaging material changes It is harder than hitherto known materials, and does not affect the material's lightness and volume.In addition, the material also has enhanced tear strength and is very suitable for printing.
Sovereign Items 1. A corrugated cardboard packaging material comprising a laminate comprising at least one planar paper layer (1, 1′, 1′′) and at least one layer of corrugated auxiliary paper layers ( 3, 13), the corrugations exhibit an amplitude (a) perpendicular to the plane of extension of the auxiliary paper layer, wherein the layers are bound together by means of an adhesive material, characterized in that, in addition to being perpendicular to the auxiliary paper, In addition to the corrugations of the amplitude (a) of the stretching plane of the layer, the auxiliary paper layer (3) further comprises substantially parallel corrugations (10) of the wave amplitude (b) present in the stretching plane of the auxiliary paper layer (10) (10). , 10′, 10′′) system.
