Hosokawa Alpine American announced at NPE 2003 that it has sold a high-performance packaging film line to Sigma Plastics Group.
Sigma, a leading film extruder based in Lyndhurst, N.J., will send the line to its Canadian subsidiary, said Alfred Teo, Sigma chairman and chief executive officer.
Meanwhile, at the Chicago show, Alpine American showed its latest Auto Therm automatic gauging system with 64 computer-controlled, segmented cartridge heaters at the die lip for improved gauge control, film flatness and wrinkle-free appearance.
The Natick, Mass., firm ran a converter-grade, three-layer blown film line equipped with a new, dual lay-on roll designed to eliminate air entrapment to give good roll geometry. The winder included new, triple-driven, bowed rolls for superior slitting quality, according to the company. Alpine's new S-wrap web path has two large-diameter, temperature-controlled rolls for warming or cooling the web, said Alpine American President David Nunes.
Nunes said the oscillating nip with new web temperature control, conforming side guides and extended carbon-fiber collapsing frame ensures film flatness. A newly designed screw with a 30-1 length-to-diameter ratio and groove-feed extruder allow process flexibility. The firm's Auto Ramp, integral to its Titan control system, can save hours of production time, according to Nunes.
