Tri-Seal International using PEN for caps
Tri-Seal International is using a polyethylene naphthalate lining material, Kaladex film from ICI Polyester, for capping bottles.
PEN provides properties such as vapor barrier, better resistance to gas transmission and advanced thermal properties when compared to PET. The Tri-Seal cap liner will be used in hot-fill food, beer and beverage packaging, health-care products and pharmaceutical applications.
Kaladex is a biaxially oriented PEN film manufactured by ICI Polyester in Dumfries, Scotland and Hopewell, Va.
Based in Blauvelt, N.Y., Tri-Seal is an independent plastic extruder and supplier of cap lining materials for food, beverage, pharmaceutical, medical, cosmetic, household and industrial chemical, automotive, marine and other applications.

Nissei promoting large-ton press line
Nissei Plastic Industrial Co. Ltd. has commercialized three upgraded versions of its FV series of large-tonnage injection molding machines.
The new machines have clamping forces of 616 tons, 720 tons and 1,430 tons. Nissei introduced the first FV, a 946-ton press, last year at IPF'96 in Japan.
Nissei has increased plasticating capacity by 20 percent, by redesigning the injection mechanism, and increasing the injection stroke to screw diameter ratio plus the screw length to diameter ratio.
Two types of injection units, and two types of screws, are available for each size of machine.
Mold opening and closing time is 25 percent faster than before. Nissei said the switch from clamp movement to high-pressure clamping is instantaneous, eliminating the time lag normally associated with the changeover.
Nissei is based in Nagano, Japan. In North America, the company is represented by Nissei America Inc. in Anaheim, Calif.

Maguire develops MicroPulse meter
Ever want to meter out just 10 pellets of color?
Maguire Products Inc. of Media, Pa., has developed what it calls a very precise metering device for its Weigh Scale Blenders, which dispenses as few as 10-20 pellets of color additive. The product is called Micro-Pulse.
The pneumatically driven system eliminates the need for auger feeders, which the company says are less reliable.
Stephen Maguire, president of Maguire Products, said the technology dramatically increases weighing accuracy and cuts equipment costs.
``Both benefits are important new steps in our drive to downsize Weigh Scale Blenders for small processing machines,'' he said.
MicroPulse uses a slide gate attached to a pneumatic cylinder with a very short stroke, of 0.125 inch. The cylinder rapidly pulses up to 20 times a second, so doses are very precise.
