| 摘要 |
The present invention relates to a layered material for use as packaging material, comprising at least two layers of cardboard and/or paper, which are connected to one another in a material-bonded manner, wherein at least one intermediate layer of a gauze-like or fabric-like reinforcing material is arranged between the layers of cardboard and/or paper. and at least one cardboard layer or paper layer has a proportion of recycled fibres of at least 80% by weight with respect to the total weight of the cardboard layer or paper layer. The invention also relates to a three-dimensional structure produced from the layered material and to a device and a method for producing a layered material for use as packaging material comprising at least two layers of cardboard and/or paper that are connected to one another in a material-bonded manner. |
