Abstract: Provided is a layer structure, preferably a security form in a book cover, particularly preferably a security form in a book cover for identification or security documents, comprising at least a) a first radiation-engravable layer a) containing at least one polymeric material; and b) at least one further layer b) containing at least one polymeric material, preferably a thermoplastic elastomer, preferably a thermoplastic polyurethane with a hardness of ?40 Shore A according to DIN ISO 7619-1-2012-2 to ?95 Shore D according to DIN ISO 7619-1-2012-2; wherein the further layer b) overlies the first layer a) at least partly to form an overlapping region, and wherein a coherent engraving partly extends in the overlap region, preferably in the further layer b), and partly in the portion of layer a) that extends outside the overlap region, most preferably exclusively in the further layer b).

Abstract: The present invention relates to a layer structure, preferably a hinge, particularly preferably a book cover, very particularly preferably a book cover for identification and security documents, comprising at least one outer layer a) containing at least one thermoplastic elastomer, preferably a thermoplastic polyurethane, and at least one layer b) containing at least one material selected from the group consisting of a polymer, a metal, a textile, a paper and a synthetic paper, or a combination of at least two of these, and also relates to a laminate comprising the above layer structure and to the method for producing same. The invention further relates to the use of the layer structure and/or laminate for the production of a hinge, preferably a multilayer book cover, especially for security and identification documents.

Abstract: The present invention provides a barrier film comprising a first layer formed from thermoplastic polyurethane (TPU) and a second layer formed from a thermoplastic polymer-based coupling agent containing an ethylene-vinyl acetate (EVA) copolymer and a second polar co-monomer polymer, wherein the barrier film has a total thickness of between 50 ?m (2 mil) and 600 ?m (24 mil), wherein the first layer has a thickness of between 20 ?m (0.8 mil) and 400 ?m (16 mil), and wherein the second layer has a thickness of between 20 ?m (0.8 mil) and 200 ?m (8 mil). The inventive barrier film may find use in colostomy, urostomy, and ileostomy pouches and in other medical applications.

Abstract: The present invention relates to a laminate comprising at least one layer a) containing at least one thermoplastic and/or thermosetting plastic, at least one layer b) containing at least one thermoplastic polyurethane and at least one component and/or a functional unit (A) which is positioned on the at least one layer a), and wherein the least regions of the at least one thermoplastic polyurethane of layer b) are designed as a foam layer. The invention also relates to a method for manufacturing such a laminate and to the use of the laminate for manufacturing security documents, preferably identification documents, smart card smartphones, tablets, displays for smartphones, and/or displays for tablets.

Abstract: The present invention provides a packaging material comprising a first layer formed from a thermoplastic polyurethane (TPU) and a second layer formed from a heat-activated, olefin-based polymer coupling agent containing an ethylene-vinyl acetate (EVA) copolymer and a second polar co-monomer, wherein the packaging material has a total thickness of between 2 mil (50 ?m) and 24 mil (600 ?m), the first layer has a thickness of between 0.8 mil (20 ?m) and 16 mil (400 ?m), and the second layer has a thickness of between 0.8 mil (20 ?m) and 8 mil (200 ?m). The inventive packaging material may be used to provide thermoformed containers and trays for storing sharp, abrasive articles such as orthopedic devices including bone implants.
