Abstract
An absorbent laminated paper article is a rectangular sheet having first parallel edges in a first direction, second parallel edges in a second perpendicular direction and an article area delimited by the edges. The article includes at least two plies adhesively bonded in a bonding pattern between the plies. The bonding pattern includes bonding elements arranged along a first set of bonding lines extending from one of the first parallel edges to the other of first parallel edges in a first direction at a first angle to the first direction and along a second set of bonding lines extending from the one of first parallel edges to the other of first parallel edges in a second direction at a second angle to the first direction, the first set of bonding lines intersecting with the second set and forming an intermeshing network of bonding lines.
