Own Quality Seal and Color Range Preview

Gabriel-Chemie

After two years of intensive development together with plastics producers and leading brands, Gabriel-Chemie GmbH, Gumpoldskirchen, Germany, has launched Pure, a unique value-added service that provides complete transparency for masterbatch applications in order to prevent any potential sensory issues. Pure uses two acknowledged industry-standard testing methods for the incoming and outgoing inspection of raw materials and masterbatches, which are delivered in the form of an upgraded masterbatch product and a full set of documentation with transparent test results.

The EU-regulation 10/2011 governs materials and objects made of plastics that are intended for food contact. Raw materials that are used in the manufacture of plastic objects and packaging may contain some impurities. These impurities are classified as Not Intentionally Added Substances (NIAS) and approved substances are included in the Union List published by the EU. With the help of modern gas chromatography, Gabriel-Chemie is capable of in-house analysis of raw materials to test for the existence of NIAS that may cause sensory issues, such as an off-taste. If unknown substances are found in the chromatogram, they are analyzed in detail using mass spectroscopy in close cooperation with the Fraunhofer Institute for Process Engineering and Packaging IVV in Germany. If the detected substances pose a potential sensory risk, the raw material is blocked. When all raw materials have been approved and released, the production can start and a certificate including a detailed evaluation of the raw materials is issued.

After successfully passing the NIAS evaluation, the approved raw materials are used to manufacture masterbatches in the test laboratory, from which injection molded parts are produced. The samples are then stored and treated in selected reference liquids, such as still water from a standardized brand, and the liquids are then blind tested for flavour deviations. A specially trained sensory panel examines and assesses the smell and flavor of the liquids in a complex organoleptic evaluation process lasting several hours. As a result, plastics converters receive a detailed test report and profile in which the organoleptic approval of the products is documented.

In addition, specific migration limit (SML)-controlled substances are disclosed at the customer’s request.

Also at Fakuma, Gabriel-Chemie showcases the latest edition of the Colour Vision range with 18 opaque plastic color samples. The new themes are Identity and DI-Economy. Besides warm red shades and sparkling effect pigments, very "high-tech"-looking colors are also on display.

The company is also announcing a solution for laser marking plastics with a metallic luster, which has been developed in close collaboration with material producers. Marking takes place under the surface and, according to the manufacturer, does not compromise the special deep luster of the plastic article. With this laser marking, depth effects are achieved that would be particularly suitable for marking logos. Very fine lines right through to moiré effects can also be produced.
