Nova Scotia printer/extruder expands

A second blown film line has been installed at Poly Cello (Amherst, NS). Poly Cello specializes in flexographic printing of food packaging and towel and tissue overwrap, and produces its film in-house to ensure high quality film for printing.
Earlier this year, the company installed its second Battenfeld Gloucester coextrusion line. The new line is designed for fast changeovers between short and longs runs, and is optimized to provide consistent film with tight gauge tolerances and suitable roll geometry for printing operations.
The line includes three Contracool(r) extruders with AC vector drives. The die is a 20-inch, three-layer Optiflow LP with internal bubble cooling.
The bubble cage has air bearings and motorized adjustments, eliminating the need for rollers, which could potentially scratch the film. Battenfeld’s Traversanip oscillating haul-off completely randomizes the film to insure optimal flatness. After the web moves down the tower, it is fed into two front-to-front 104-inch-wide Model 1011S single-turret winders. These winders have loadcell tension control, horizontal layon assemblies and 42-inch roll diameter capability, ensuring the best possible roll quality for secondary processing.
