Abstract
Abstract A card, such as an ID card, is composed of the following layers: at least one core layer containing at least one first core component layer of a first composition, consisting of a polypropylene block polymer and/or polyropylene homopolymer or a mixture thereof and a second core component layer provided on at least the exterior face to which an outer layer has been laminated and is made of a second composition, consisting of unoriented polypropylene or an unoriented copolymer; at least one outer layer containing at least one outer component layer made of a third composition of polypropylene homopolymer and a second outer component layer provided on at least the exterior face with which the outer layer is laminated to the core layer and which contains a fourth composition of unoriented-polypropylene or an unoriented copolymer. The first and second core component and outer component layers are solidly connected with each other by coextrusion.
