Elopak is a Norwegian company producing cartons for liquids, starting with aseptic gable top cartons for milk. The company was founded in 1957 by Johan Henrik Andresen and Christian August Johansen as a European licensee of Pure-Pak, the Elopak name standing for European License Of PURE-PAK. In 1987, Elopak bought the Ex-Cell-O Packaging Systems Division from which it was originally a licensee, and hence got full ownership of Pure-Pak.
