General Films Inc. will more than double its output of high-barrier films with a new Battenfeld Gloucester line being installed at its Covington, Ohio, plant.
President Tim Weikert said in a telephone interview that the private firm is investing about $3.5 million in the project, including the nine-layer film system, site work and ancillary services. The line is expected to begin operating in August.
``Due to an increase in demand for high-barrier structures and our desire to supply more advanced films, we needed to supplement our capacity,'' Weikert said in a news release.
``We decided to go all the way to a nine-layer production capability.''Weikert said General Films has been extruding barrier film since 1988.
The new line will run a variety of constructions incorporating nylon, polyethylene and ethylene vinyl alcohol copolymers. The line also will be able to corona-treat either side of a web and produce roll stock, tubular films or bags in-line.
General Films now makes mono-, three- and five-layer films for bag-in-box systems and modified-atmosphere packaging, and for packaging perishables such as cheese and meat. Other end uses are converter films, industrial packaging and custom bags. The Covington operation has seven blown film lines - three of which are Battenfeld Gloucester systems - a profile line for food-grade tubing and bag and pouch machines.
The new line includes nine ContraCool extruders, seven of which are 2 inches in diameter, based on an air-cooled design.
The two 2½-inch extruders feature shallow barrel grooves to improve conveying efficiency and to prevent lock-up that can occur with unlubricated nylons and to avoid shear-off of soft plastomer pellets, according to Battenfeld Gloucester Engineering Co. Inc. of Gloucester, Mass.
Battenfeld Gloucester's encapsulated feed technology streamlines die-flow passages and permits quick changeovers. Other features ensure tight layer and gauge control.
General Films employs about 75 and has annual sales of more than $15 million, Weikert said. It has been extruding film since 1967.
