Battenfeld Gloucester Engineering Co. Inc. has added a three-layer blown film “swing” line at its technical center in Gloucester, Mass.
The line began operating in May. It allows customers to test high-molecular-weight high density polyethylene, high-stalk bubbles on Battenfeld Gloucester equipment.
The production-size line features three Contracool extruders, one grooved-feed extruder with a screw diameter of 3.2 inches, and two smooth-bore extruders, each with a 2½-inch screw diameter. All the extruders have a 30-to-1 length-to-diameter ratio.
Each extruder has a three-component AcuraBlend feed-throat blending and loading system. Dynisco EM-35 and EM-25 screen changers are mounted on the extruders.
The die packages consist of a 16-inch, three-layer Optiflow low-profile IBC die for conventional bubbles, with parts to change the die diameter to 10 inches to run three-layer HMW HDPE high-stalk bubbles.
Also at its technical center, the company has a five-layer sheet line, a seven-layer cast film line and a seven-layer blown film line.
