Equipment upgrade gives film producer multi-layer capability

Cast film extruder Copol International (North Sydney, NS) is entering the multi-layer film market with a coextrusion line from Davis-Standard. Copol, a supplier of unoriented cast polypropylene films to North American converters, is integrating multi-layer technology to strengthen its product offering and competitive advantage over offshore producers.
"Adding three-layer extrusion capability will enable us to improve processing rates while extending our product range to films with enhanced performance properties for specialty packaging applications," explains David Sawler, Copol’s vice-president of operations.
The equipment upgrade, scheduled for June, consists of two satellite extruders, a co-extrusion feedblock, die modification, gravimetric feeder and loading system.
Copol’s product range includes homopolymer, copolymer and metallocene films in widths from 1 to 70 in., and gauges from 0.90 to 10 mil. The films are used in flexible packaging applications such as retail product bags, food packaging, industrial products and medical products.
