The Tritium™ Multipacker is a continuous motion multipacker with single-, double- and three-lane configurations. The system arranges products into compact pack patterns and wraps the configurations in film, eliminating the need for trays and pads. The packs are sent through an energy efficient heat tunnel to tightly shrink the film around each multipack, producing a consistent, wrinkle-free bull's eye and bottom seal. The machine is equipped with easy-access "gull wing" guard doors that provide a clear view of all moving belts and chains, enabling "walk-by maintenance." To facilitate maintenance, many steel chains have been replaced with timing belts which require no lubrication and create a quieter machine.
