Dow Chemical is touting the value of plasma-coated polypropylene containers as a PET replacement in smaller bottles.
In testing, plasma-coated PP bottles can be down-gauged to create 10% cost savings compared with PET, said Jason Brodil, plastics development specialist for Midland, Michigan-based Dow.
At the Packaging Conference held 4-6 February in Las Vegas, US, he added that the material also offers similar oxygen transmission rates. Test runs of 500 bottles have been accomplished in bottles less than 32 ounces in size, including 500-milliliter bottles for isotonic drinks.
