For insulation manufacturer Litepac, shrink wrapping stacks of polystyrene insulation was a costly process-both in money and in material waste. The Granard, County Longford, Ireland-based company's change to a System 2000 Double Stretch Bander from EDL Packaging Engineers (Green Bay, WI) not only provided savings but ended the potential problem of board distortion caused by heat from shrink wrapping.
The Model 88-4000CS stretchwrapper from Intl. Packaging Machines (Naples, FL) has a warm wire film cutter that reduces fumes and wide brush wiping action to eliminate trailing end film "tails." Wraps loads weighing up to 4ꯠ lb on a 14 rpm variable-speed turntable.
The Model 60 continuous-motion shrink wrap system from Arpac (Schiller Park, IL) for high speed beverage hot-fill lines wraps up to 75 trays/min. Digital controls simplify film and size changeovers; an automatic setup package for simplified resetting is optional.

An excellent barrier to oxygen, moisture, light, flavor and odor, applications include sterile packaging of medical supplies and aseptic packaging of oxygen-sensitive foods, such as juices, purees and pastes.
