Cast polypropylene film producer Copol International Ltd. will diversify into coextruded films by upgrading one of its existing film lines.
Copol, based in North Sydney, Nova Scotia, will spend more than C$1 million (US$750,000) on the project, David Sawler, vice president of operations, estimated in a telephone interview. The firm will install new equipment on an existing Davis-Standard line in June.
Two Davis-Standard satellite extruders form the core of the upgrade.
Davis-Standard also will add a coextrusion feed block, modify dies and install a gravimetric feeder and loading system. Sawler said his company separately will install a Pillar Technologies surface treater on the line.
The upgrade will boost Copol's product line to include specialty three-layer films suited to high-speed form, fill and seal applications and for metalizing.
At first, Copol will coextrude PP layers, but the firm eventually expects to add other resins to the mix.
Sawler said if the coextrusion program is well-received in the marketplace, Copol will consider installing a new, dedicated coextrusion line, rather than convert another of its other three cast film lines.
The company now makes monolayer film for flexible packaging and industrial and medical uses. Sawler said cast, nonoriented PP films excel in impact strength, clarity and dimensional stability and, compared with polyethylene film, have higher barrier properties.
Copol's current product line includes homopolymer, copolymer and metallocene-catalyzed PP films in widths up to 70 inches and gauges from 0.9-10 mils. It sells across Canada and in the eastern United States.
Privately held Copol was formed in 1992. Sawler said U.S. and Canadian investors in the company do not release sales figures.
