[Abstract] A press roller (10) for a laminating machine for producing packaging material, the packaging material comprising a body layer (40) made of paper or cardboard, the body layer having a through hole (42), The body layer has a barrier layer (44), a plastic liner (46, 47) and a laminated thermoplastic film (43) on one side thereof. The plastic liner is disposed on the outside of the barrier layer. Arranged between the body layer (40) and the barrier layer (44), the pressure roller has a sheathing surface, the sheathing surface facing a layer of inner surface layer (12), the inner surface layer is composed of an elastic material, Has a first hardness and a first thickness. According to the invention, an outer layer (13) is arranged on the outer side of the inner layer (12). The outer layer consists of an elastic material having a second hardness and a second thickness, the first hardness being greater than the second hardness. A thickness is greater than the second thickness. The invention also relates to a method for producing a packaging material and a packaging material produced using the method.
