Blown film system boosts output rates
Davis-Standard LLC's blown film pilot line at its laboratory in Bridgewater, N.J., uses a Triple Lip air ring and the company's vertex die, to give increased cooling capacity and output rates.
The Triple Lip uses one air ring, blower and chiller instead of two rings. It features a counter-cooling design along the hi-stalk and an easily adjustable elevator system.
Pawcatuck, Conn.-based Davis-Standard's blown film systems business is in Bridgewater.

Flexicon Corp. offers plantwide batching
Flexicon Corp. of Bethlehem, Pa., said its plantwide batching system simultaneously weighs up to seven major ingredients received in bulk bags, and an unlimited number of minor ingredients received in 50-pound sacks, pails or boxes. The system conveys weighed batches to a downstream blender that feeds a bulk bag filler and a paper sack filling machine.
Components include five loss-in-weight Bulk-Out bulk bag dischargers, two loss-in-weight bag dump stations, a check-weighing hopper, a Twin-Centerpost bulk bag filler, a Pneumati-con dilute-phase pneumatic-conveying system and a programmable control package.

Charles Ross debuts three-agitator mixer
Charles Ross & Son Co. has introduced the VersaMix multishaft mixer, which uses three independently driven agitators working in tandem.
A high-speed disperser draws powders into the liquid batch through a powerful vortex. The rotor-stator can do several tasks: breaking down aggomolerates, accelerating homogenization and preparing fine droplets in an emulsion. The low-speed anchor promotes bulk flow and uniform batch temperature, which it scrapes the side walls and bottom of the vessel.
Charles Ross & Son is in Hauppauge, N.Y.
EDI develops ‘active microlayer' system
Flat-die maker Extrusion Dies Industries LLC has developed an “active microlayer” technology that combines the concepts of active packaging and microlayer extrusion.
It yields film and sheet in which the multiplication of layers is applied not only to the barrier polymer, but also to active components such as oxygen absorbers or desiccants.
EDI's previous research has showed that, by dividing and recombining the barrier layer to create many microbarrier layers, it is possible to significantly increase the shelf life of retort and hot-fill containers, standup pouches and vacuum-skin packaging. Now researchers at EDI's technology center in Chippewa Falls, Wis., have taken that a step further by incorporating active components in layers outside the barrier core, then subjecting those components to layer multiplication as well.
“After encountering numerous active-component layers, oxygen is largely absorbed before it even reaches the barrier layer, as is moisture before it gets a chance to degrade barrier material such as ethylene-vinyl alcohol,” said Gary Oliver, EDI's vice president of technology.
Even when the film or sheet contains dozens, or even a hundred or more microlayers, it is no thicker than standard sheet with three to 11 layers, according to EDI.

Siapi creates lighter water container
Siapi srl, the Italian builder of stretch blow molding machines, has developed what it calls the lightest 5-gallon container for water coolers — a one-way PET container using for the Turkish market.
The bottle is molded on Siapi ES1S and ES2S machines, at a rate of 600 bottles per hour with one mold cavity, or 1,100 bottles an hour with two cavities.
Siapi said the market standard size is 390 grams, but the Siapi design is just 330 grams.
Beyond current customers in Turkey, Siapi said the light container is getting attention from bottlers in the Middle East.
Siapi is based in San Vendemiano, Italy. Siapi America Inc. is in Norcross, Ga.

Priamus enhances monitoring system
Priamus System Technologies LLC has introduced a new method of real-time monitoring of melt viscosity during injection molding, by using the shear rate and shear stress.
President Susan Montgomery explained the technology at the Priamus booth during Penn State Erie's Injection Molding Conference, held earlier this year at the college in Erie, Pa.
She said the Priamus system measures viscosity changes as they happen in the mold during each shot, saving time from off-line measurement using a rheometer.
It uses two sensors: a pressure sensor and a temperature sensor. The shear rate is calculated from the difference in time that the melt takes to flow the distance between the pressure sensor and the temperature sensor. Shear stress also is a measure of time.
Using the Priamus data, Montgomery said, you control the viscosity by manipulating barrel temperature and injection speed.
Montgomery made a presentation at the Penn State Erie conference.
Priamus System Technologies is in Brunswick, Ohio.
