Danafilms Inc. has added a Battenfeld Gloucester blown film line to its Westborough, Mass., plant, bringing the total number of lines there to 14.
The company's sales manager, Steve Crimmin, said in a July 18 telephone interview that the company has spent $3 million equipping the 30-year-old facility with the new Battenfeld line and in upgrades to older machinery.
``We want to eliminate any downtime customers might have due to film issues,'' Crimmin said in a news release.
The new line will add more than 5 million pounds of capacity and has winders that can handle rolls up to 78 inches wide and 40 inches in diameter.
``This will reduce the number of changeovers [on] long runs,'' Crimmin said. ``We've added internal bubble cooling to increase our throughput so that we can always keep up with demand, and everything is computer-controlled for quality and consistency.''
The new line includes an Autoprofile air-ring system that monitors and corrects the thickness of blown film as it exits the die, Crimmin said. It adjusts the thickness of the film by firing heated air from 96 heating components at exact locations on the surface of the bubble.
The heating components interface with an Extrol microprocessor via a thickness gauge. The air jets thin the bubble wall where required.
Other plant improvements include oscillating hauloffs on three other blown film lines to evenly distribute any gauge imperfections, thus increasing uptime for high-speed printing and conversion.
Danafilms has been manufacturing polyethylene films since 1970. It supplies converters with monolayer and multilayer coextruded films.
The company processes low and linear low density PE, metallocene-catalyzed PE and ethylene vinyl alcohol resins. It operates plants in Westborough and Franklin, Ky.
Danafilms ranked 84th among North American film and sheet producers in Plastics News' 2007 survey, with fiscal 2006 sales of $57.8 million. The company employs 94.
