Klockner Pentaplast GmbH in Germany, a global producer of thin sheet for thermoformed packaging, is introducing an unusual “intelligent” rigid film for trays. It changes color in response to a temperature change within a 10° C window. A variety of pairs of colors—one organic and one inorganic—and temperature windows can be selected. Both colors are visible until the temperature trigger is reached. Then the organic color disappears. Klockner’s first thermochromic package will be a freezer-to-microwave tray that will change from lavender to blue to indicate when a frozen food has been heated in a microwave oven. It’s expected to be launched in Europe later this year. Klockner Pentaplast presented the concept at November’s Multilayer Packaging Films 2008 conference in Cologne, Germany, sponsored by Applied Market Information in the U.K. +49 (2602) 915-0 • www.kpfilms.com

    New cost-effective technologies are designed to make aluminum an attractive alternative to tool steels in a range of plastics molding processes. One method uses a plasma technique to convert the aluminum surface into a hard, dense, wear-resistant ceramic. Another approach uses electro-deposition to apply a surface coating with high hardness, corrosion resistance, and chemical resistance.
