The invention relates to as method for producing a molded part in an injection mold, which molded part is made of plastic and provided with a UV-cured paint, wherein the UV-cured paint forms a visible surface designed as a functional surface. The invention further relates to such a molded part provided with a UV-cured paint, said molded part having a visible surface designed as a functional surface, wherein the UV-cured paint forms said visible surface.

Method for producing a molded part made of plastic and provided with a UV-cured paint, and said molded part

The present invention relates to rear-projection film with 'day/night' effect comprising at least two layers, where the film comprises at least one grey layer comprising at least one thermoplastic with transmittance of from 10% to 70% in the visible wavelength range and at least one layer comprising at least one thermoplastic and scattering particles, and also to the use of the said films as rear-projection areas in the vehicle interior sector.

Rear-projection film having a 'day/night' effect

The invention relates to a transparent thermoplastic material, containing 0.0001 to 2 wt. % of substantially flat metal identification platelets with a largest length elongation of less than 200 &#x3bc;m and a thickness of 2-10 &#x3bc;m, a round or n-angled shape where n&#x2267;4, wherein the metal identification platelets do not have any recesses or have recesses that lie substantially in the center of the metal identification platelet, do not come closer than 20 &#x3bc;m to the circumferential outer edge of the metal identification platelet, and do not account for more than 30% of the surface area of the metal identification platelet. The invention also relates to the production thereof and the use for producing films for personalization of a card layer composite and data carriers in card form, especially smart cards, magnetic strip cards, identification cards and the like.

Thermoplastic comprising metal identification platelets

The invention relates to layer structures for ID cards on which information can be written by laser engraving and which have an additional layer that is applied to the card body after the laser engraving and restricts or completely prevents subsequent writing on the card by means of laser engraving, and consequently prevents falsification of the identifying information contained, and relates to a method for blocking the laser engraving writability of layer structures on which information can be written by laser engraving.

ID cards with blocked laser engraving writability

Latent-reactively glued TPU/PC layer materials

A method of making a plastic molding is disclosed. The multi-step method entails applying a metallic layer 20 to 150 nm thick to a translucent plastic film having a thickness of 50 to 750 &#x3bc;m, removing part of the metallic layer, and applying to the metallized side of the film an adhesive layer 5 to 50 &#x3bc;m in thickness to obtain a product, and injection molding the product with a translucent thermoplastic. The plastic molding thus made is suitable for the preparation of keys, fittings, trim strips, reflectors, keyboards, casings, shields, advertising panels and packaging items and identification cards.

Method of making metallized plastic moldings and their use

A reinforced polyamide molding composition is disclosed. Characterized in that its viscosity at a shear velocity of 10 s is greater than 1000 Pas and a shear velocity of 1000 s is less than 300 Pas, at processing temperatures of 40 to 80&deg; C. above its melting point, the composition is particularly suitable for thermoforming applications.

Thermoformable polyamides

Described is a molded plastic article which includes a barrier film. The molded plastic article is prepared by a process which involves: (a) providing a barrier film comprising at least one polymeric layer, the barrier film having a first surface and a second surface; (b) placing the barrier film in a mold such that the first surface of the barrier film is in contact with at least a portion of the interior surfaces of the mold; (c) injecting a polymer (e.g., a molten thermoplastic polymer) into the mold, the injected polymer contacting the second surface of the barrier film; and (d) removing the molded plastic article from the mold. Also described are molded articles according to the present invention, which include, for example, plastic containers, plastic fuel tanks, plastic storage units, plastic fascias and plastic motor vehicle interior cladding materials.

Molded plastic article comprising a barrier film

A multilayerd, biaxially stretched tubular film having the following sequence of layers, &verbar;A&verbar;B&verbar;C&verbar;D&verbar;E&verbar;F&verbar;G&verbar;, is described. Inner layer A contains at least one member selected from the group consisting of aliphatic (co)polyamide and partially aromatic (co)polyamide. Core layer E, consists essentially of at least one member selected from the group consisting of aliphatic (co)polyamide and partially aromatic (co)polyamide. Outer layer G contains at least one member selected from the group consisting of aliphatic (co)polyamide and partially aromatic (co)polyamide. Interlayer C is polyolefinic, has water vapor barrier properties, and is interposed between inner layer A and core layer E. Interlayer C is directly attached to layer A via coupling layer B and to layer E via coupling layer D. Coupling layers B and F each independently contain a modified polyolefin. Interior layer F has oxygen barrier properties, and is interposed between outer layer G and core layer E. The composition of inner layer A, core layer E and outer layer G are each independent one from the other.

Multilayer, biaxially stretched, high-barrier plastic skin

The present invention relates to an at least single-layer, tubular, biaxially stretched, biodegradable and compostable food casing, in particular a sausage casing, at least one layer consisting substantially of a thermoplastically processable, biodegradable polymer.

Biaxially stretched, biodegradable and compostable sausage casing

An at least 4-layer co-extruded, biaxially stretched, tubular seamless casing for sausages to be heated in water and cooking-sausages, having improved tearing properties in the filled state associated with a decreased tendency to burst open when the sausage product is first cut, containing at least two layers composed predominantly of aliphatic polyamide, which form the inner and outer surfaces of the tube, and at least two additional layers, which are enclosed by the inner and outer polyamide layers, with at least one of the enclosed layers acting as a water vapor barrier and having the structure of a polyolefin and at least one other of the enclosed layers acting as an oxygen barrier and consisting mainly of ethylene vinyl alcohol copolymers, the quotient of the tear resistance in the transverse direction to the tear resistance in the longitudinal direction lying between about 0.65 and 0.85, with the degree of surface stretching of the film product being between 8 and 11. The process of preparation is also set forth.
