<p>The invention provides a planar (1) stiffener for use in packaging of detergent bars, the stiffener having a machine-direction (MD) and perpendicular thereto a cross-direction (CD), characterised in that said stiffener has a plurality of ribs (2) along its cross-direction. The stiffeners when used in packaging soap or detergent bars are less prone to deformation along the lateral sides (6, 7) and edges of the package (3). This makes the stiffener characteristics more suitable for retaining the envelope wrapped shape of the package to a significant extent until the end consumer point.</p> |
