W & H: Big demand in equipment for tacky film

Demand for blown film equipment to handle tacky web has increased so much that extrusion equipment manufacturer Windmöller & Hölscher, based here, reports that it is shipping a zero-contact film guiding system with every other oscillating haul-off ordered.
The company’s Nostic oscillating haul-off, introduced in 1997, allows processed film to hover over the turning bars on a cushion of air. The system prevents sticking, maintains optical properties, and avoids scratches and marks on the web surface of protective film and stretchwrap.
