Abstract: The invention relates to a method and system for optical product authentication, in which a product is labeled with optically active particles, a reference image is recorded in a registration step and a recognition image of the optically active particles is recorded in a recognition step. The product is then authenticated by comparing image data or a coding derived from image data in the registration step versus the recognition step.

Abstract: A double-layered or multilayered thermoformable composite film having a metallic appearance that includes a first film with a metallized surface and a gloss value in the range of 50 to 600. The inventive thermoformable composite films have an appearance that is the same as that of a composite film including a metallic foil, particularly an aluminum foil.

Abstract: A film is provided that has three layers. The inventive films are made of semicrystalline or amorphous copolyesters and further include two exterior layers and an interior layer. The exterior layers include neopentyl-glycol-modified polyethylene terephthalate, while the interior layer includes 1,4-cyclohexanedimethanol-modified polyethylene terephthalate. The inventive films advantageously provide a shrink film that has a shrink performance similar to that of shrink films made of PVC.

Abstract: A coating 8 made of polyvinylidene chloride contains particles 12 made of HDPE. Other particles can also be embedded in the coating, such as polymers from the group LDPE, LLDPE, PP, PVDC, PVC, polyamides, polyurethanes, polyacrylates, polystyrenes, acrylonitrile-butadiene styrene polymerizates (ABS), PTFE, hard waxes, synthetic resins, as well as mixtures and copolymerizates thereof. The coating 8 is applied to a film 9 of a composite which features a carrier film 11, to which the film 9 is laminated by means of an adhesion promoter 10 (FIG. 2).

Abstract: The invention relates to a molding mass made from vinyl chloride polymer or polyvinylchloride at 5 to 94 wt. % and a K value of 50 to 90 additives at 2 to 25 wt. % and a polymer, whereby the weight percentages relate to the total weight of the molding mass. The polymer is a semi-crystalline or amorphous polyester. The film is produced from the molding mass by plastifying and fusing the same and calendering or extruding the same to give a film with a thickness of 100 microns to 1 mm. By means of subsequent in-line or off-line method steps, the film, for example, by means of drawing with a drawing degree of 1.3 to 7, can be further processed to give a thin high-shrinkage film.

Abstract: A method is provided for producing colored molded bodies based on the following steps: (a) plasticising a polymeric material and blending the material with one or more dyes to form a molding compound by means of a gelation unit equipped with a metering apparatus for dyes; (b) optionally temporarily storing the molding compound obtained in step (a); (c) charging a molding device with the molding compound; and (d) producing the molded body; wherein the ratio of dye to polymeric material is automatically regulated using a colorimeter and an electronic control, and in step (a) color values are measured at the molding compound located in the gelation unit and transmitted as a signal to the electronic control.

Abstract: The invention relates to a molding compound including a polyester resin composition, ABS components, waxes, matting agents and optionally vegetable oil, which is used to produce films with a low luster, improved thermal resistance of the film and/or of the surface structure and an increased shrinking onset temperature, in addition to a modified shrinkage progression in comparison to films without the aforementioned additives. The fraction of the polyester resin composition is between 30 and 97 wt. % and the fraction of the additives between 1.5 and 70 wt. %, in relation to the total weight of the molding compound. The films are used as shrink-wrapping and packaging films and films for furniture and printed circuit boards.

Abstract: A packaging film which contains pigment particles randomly distributed in a low surface-area density is used for the authentication of products. An imaging device is used to record a first digital image of a packaged product. The positional coordinates, and optionally the color values, of the pigment particles contained in the packaging film are determined from the digital image by means of a computer program and an identification code is calculated from the coordinate or color values and stored in a database. To authenticate the product at a later time, a second digital image is recorded and a test code is determined and compared with the recorded identification code.

Abstract: The present invention relates to a deep-drawable multi-layer film having low water vapor and oxygen permeability, the inventive film being suitable for blister packaging and preferably including a layer composite specifically a PVC/PVDC/PCTFE/PVC composite.

Abstract: A plastics film 1 composed of rigid polyvinyl chloride serves as backing film for a sleeve label. The sleeve label can be applied by adhesive bonding and shrinking onto a peripheral surface of the cylindrical body. A protective covering film 2 has been laminated onto the plastics film 1. The plastics film 1 has been stretched in the machine direction of a calender and has a longitudinal heat shrinkage of from 40 to 60%, based on the unstretched plastics film. Perpendicularly to the machine direction of the calender, the heat shrinkage of the plastics film is from 0 to 10%.
