Developed in close cooperation with ExxonMobil, the new stretch-hood systems have been tested extensively with coextruded films from ExxonMobil’s new Nexxstar™ resin. The Lachenmeier stretch units are developed to handle the thinner film without overstretching it and without destroying the holding forces of the film. A main advantage of the new stretch-hood machine is the heavy-duty stretch units, which are based on hydraulic stretching. Each gripper has a stretch force exceeding more than 1 ton.
