  • Impact Resistance of PP and ABS Regranulates – Safety, Testing, and Real-World Performance

    of Dr. Magdalena Laabs

    A brittle bumper after a minor impact. A pipe damaged during installation. Unpredictable behavior at low temperatures.
    These are real-world failures often linked to one key property: IMPACT RESISTANCE—the ability to absorb impact energy without brittle fracture.
    This article explains where recycled plastics are used in vehicles, why safety depends on controlled impact resistance, and how PP and ABS regranulates should be tested. It covers Charpy vs. Izod, standard requirements, specimen preparation, and how impact resistance changes after recycling

  • International Women's Day, Tulips, and… Plastics?

    of Dr. Magdalena Laabs

    How Are Artificial Tulips Made to Look Just Like Real Ones? The Secret of Lifelike Flowers! 🌷🌷🌷🌷🌷🌷🌷🌷🌷🌷🌷🌷🌷🌷🌷🌷🌷

    I love flowers—my garden is full of roses, daffodils, peonies, and, of course, tulips. 🌷 I especially adore those in unique colors: black, blue, purple, orange, and two-toned. On my trips from Amsterdam, I used to bring home bulbs of these extraordinary varieties. I planted them in spring, admired them for a few weeks, but after winter, only the white and red ones survived. Year after year, my garden naturally turned into the colors of the Polish flag.

  • ♻️🌱 Thermoforming Films – A Business Idea in the Packaging Industry

    of Dr. Magdalena Laabs

    What is the market for thermoformed film packaging?

    The packaging industry is growing rapidly, and the demand for hygienic, aesthetic, and eco-friendly solutions is on the rise. Thermoformed packaging, made from polypropylene (PP) or polystyrene (PS) films, is increasingly used in the food, electronics, and industrial sectors.

    If you’re looking for a business idea, investing in the production of these films could be a great opportunity. The production process begins with a cast film extrusion line, which produces thick films ranging from 0.3 mm to 1 mm. These films are then processed on another machine called a thermoformer to create specific packaging products.

    This article will show you how investing in a cast film extrusion line can be the first step toward entering this lucrative market.
