17 Jun 2020 --- Elopak has modernized its famed Pure-Pak carton with the launch of Pure-Pak Imagine in what the company calls its “most environmentally-friendly carton to date.” The new carton swaps the conventional plastic screw cap for a fold-back, top fin opening, which reduces the total plastic content by 46 percent. Pure-Pak cartons are made from renewable Natural Brown Board and a wood-based bioplastic barrier, using an estimated ten times less plastic than standard PET bottles.
