Justin’s wanted a high-shelf-profile, square-shaped plastic container that could stand out on the grocery shelf. The TricorBraun design and engineering staff developed a custom mold for a square, clear PET peanut butter jar. Jar volume is 16 ounces. The PET jars are made on a single-stage machine from Nissei. The empty jars weigh 50-g and measure 4.52 inches tall with a diameter of 2.93 inches. The 70mm diameter polypropylene closures are supplied by Phoenix Closures.
Justin’s Nut Butter introduced the new packaging in June 2010. Chief executive officer Justin Gold notes, “The performance of our new square jar has been tremendous. Not only does it clearly differentiate us from our competition, but it also allows us more shelf facings on the same retail footprint.”
