Sigma Stretch Film Adds Two Gloucester Lines

GLOUCESTER, MA | Leading US stretch film producer Sigma Stretch Film recently installed two stretch film lines from Gloucester Engineering, including a five-layer cast stretch film line to the company’s facility in Shelbyville, KY, and a five-layer blown stretch film line in Belleville, ON, Canada.

The two production lines will support Sigma’s growing business and with the on-time delivery from Gloucester, the cast film line has been in production since October 2013 and the blown film line will be in production in early 2014.

“We made our decision based on experience, the superior technology offered by Gloucester Engineering, and the outstanding durability of their equipment. We consider Gloucester’s 1002-Series winding technology to be the most advanced in the industry,” said Per Nylen, executive VP of Sigma Stretch Film.

The five-layer nine-up cast stretch film line includes four Contracool extruders equipped with PIB injection that feed a Cloeren feed block and auto die. Also included is a casting unit with temperature control unit (TCU) and a 1002-DS Surface-Center winder with dual overlapping single turrets. The line is enhanced with resin vacuum loading, loss-in-weight blending, gauging, profile control, and a trim reprocessing system all controlled by the Extrol 6032 control system.

The five-layer blown stretch silage film line includes five Contracool extruders equipped with PIB injection feeding a low profile five-layer IBC die and air ring. Also included are a bubble cage, Traversanip oscillating primary nip roll with composite roller collapsing frame, secondary nip roll, and a dual turret 1002-D Surface-Center winder. The line is enhanced with resin vacuum loading, feed throat gravimetric blending, and a trim reprocessing system all controlled by the Extrol 6032 control system, and containerized controls.
