Abstract
A housing element of a product includes a foil having a decorated side, where this decorated side of the foil is covered by a grip layer for realizing a grip effect. The other side of the foil is covered by a supportive layer. The grip layer may have a rib structure. Each of the supportive layer and the grip layer is applied to the foil in an injection molding process. A processing temperature of the material of the grip layer is significantly lower than an activation temperature of printing ink of a decorative covering of the foil, so that washout of the printing ink is prevented. Further, material of an adhesive layer of the foil is configured to establish adhesion to the material of the grip layer at this relatively low temperature.
