Kortec bringing skill to caps and closures
Kortec Inc. brings its barrier-layer technology to one-piece caps and closures helping to better preserve freshness in foods and beverages. They also are less expensive than traditional two-piece closures, according to the company in Ipswich, Mass.
Kortec is known for its multilayer technology for producing PET containers. The barrier caps can be made in a single molding operation, with no need for a secondary step.
We can now produce an entire container, including the closure, with our multilayer technology, said Russell Bennett, Kortec's vice president of sales and marketing. This allows for the production of beverage and food containers that will stay fresh for much longer time periods on store shelves.
Bennett said barrier caps usually are made of two or more pieces, the plastic cap and the seal. What we have developed allows production of a one-piece cap that has the same or better performance, he said.

Davis-Standard, NO.EL unite for film systems
Davis-Standard LLC and NO.EL Automazione Industriale, the Italian maker of coreless winders for stretch film, have signed an exclusive agreement to jointly supply in-line coreless stretch film systems, up to 120 inches wide, to the converting industry.
The alliance combines NO.EL's coreless winding technology with Davis-Standard's extrusion and processing expertise. The companies are working on wider systems.
The technology eliminates the need for a cardboard core.
NO.EL's in-line coreless winders allow processors to produce conventional cast stretch film for hand-wrap or machine-wrap at line speeds of up to 2,300 feet per minute. NO.EL's in-line pre-stretching technology, in conjunction with Davis-Standard's cast stretch lines, can run line speeds up to 3,600 feet per minute.
Hassan Helmy, executive vice president of Davis-Standard, said Milan-based NO.EL has reliable technology that is a good fit with his company's Black Clawson stretch film equipment. There are several coreless suppliers, but NO.EL is the only one with proven in-line and off-line production success, Helmy said.
Davis-Standard is based in Pawcatuck, Conn.

Cooling system works inside, outside of pipe
Battenfeld Extrusionstechnik GmbH's new efficient air cooling (EAC) internal air-cooling system helps pipe extruders improve quality and output.
EAC can be used during production of both monolayer and multilayer polyolefin pipes. It can be directly integrated into new dies, or retrofitted to existing Battenfeld VSI dies.
EAC cools pipes from inside and outside, using only air. The interior of the pipe is cooled by using air exchange, with the hot air getting sucked off. At the same time, the mandrel inside the die is cooled via a special mechanism. The outside of the pipe is cooled via a special mechanism, and also supplied with cooling air.
In this way, the pipe is cooled very evenly, reducing tension inside the pipes and deposits on the inner surface, according to the company in Bad Oeynhausen, Germany.
Improved product quality occurs because the sagging effect is avoided, and the deformation of pipe ends following cutting is significantly reduced, the company said.

Plastic Can offering 2-stage PET paint can
London-based Plastic Can Co. is seeking licensees in North and South America for its patented, two-stage PET paint can.
The company's PET paint can is made by two-stage reheat blow molding, unlike most others that are injection molded from polypropylene, which it claims cannot hold solvent-containing paints. PP containers, like traditional metal paint cans, are manufactured in one step and incur costs when the bulky containers are shipped to the paint filler.
PCC's PET can handle both solvent- and water-based paint, with a crystal-clear container. Injection molded preforms can be made centrally and then shipped to the paint-filling plant, where they are blow molded into finished cans.
The preforms are delivered with a ready-fitted handle, which clips onto the rim of the preform and remains in place during the reheat-blow process and paint filling.
PCC said the cans can be molded from post-consumer PET.
The company has developed a ring-pull lid so the lid can be removed by hand, without requiring a tool. The ring pull can be clipped back onto the lid for repeatable use.

Bay latest pelletizer improved, renamed
Bay Plastics Machinery Corp. has improved the design of the cantilever-style pelletizer, renaming it the Z Series.
"The changes are focused on making the machine more robust and easier/faster to clean between material changeovers," said Tom Kernstock, executive vice president. "The compounding and colorant industries have changed to require shorter runs and more frequent changeovers to meet the customer needs of smaller lot sizes."
The auxiliary equipment maker in Bay City, Mich., made several key changes to reduce the time it takes to clean the machine, and remove every pellet from the previous run. The redesigned feed table is easily removed without the use of tools, giving complete access to the cutting chamber.
BPM has made the discharge chute removable, ensuring complete clean-out between material runs. Other features include a supported bed knife holder.

Maguire enhances blender controller
Maguire Products Inc. said a touch-screen control now available for its weigh scale blender provides the same intuitive access as the company's widely used "thumbwheel" controller.
It also gives faster response and new capabilities for processing jobs that are especially challenging, according to the auxiliary equipment maker in Aston, Pa.
The key to greater response is a computer with a Linux operating system, according to Pat Smith, vice president of marketing and sales. "While the controllers for blenders operated by [programmable logic controllers] function literally as remote devices, with a short but perceptible lag between input and response, our touch screen is actually the display of an onboard computer, and its response is lighting-fast," he said.

Dukane offers welder for medical market
Dukane Corp.'s Ultrasonics Division has introduced what it claims it the first servo-controlled ultrasonic welding system for medical applications and other high-value parts.
The iQ welder is based on Dukane's new "Melt Match" technology, which delivers improved repeatability, stronger welds, easier calibration validation and lower manufacturing costs vs. standard pneumatic welders.
Melt Match precisely controls the collapse-speed profile during the weld. According to the company, collapsing too slow may cause material degradation while collapsing too fast could result in cold forming. Melt Match precisely matches the collapse speed during the melt phase - penetrating deeper into the bond and creating a larger affected heat zone, to give superior bond strength.
Typical pneumatic welders continue to travel during the hold phase, but a servo-controlled welder can stop and/or continue to collapse a specified distance and speed during the hold phase.
Dukane is based in St. Charles, Ill.
Kreyenborg improves screen changer filter
Kreyenborg GmbH has proved its V-type screen changer in processing PET, and now the first filter with its special power-backflush technology is in operation in a polyolefin line: the direct extrusion of shredded high density polyethylene resin recycled from blow molding, to make sheets for the automotive industry.
The customers only wanted to use post-industrial and post-consumer recycled HDPE for the application, the firm said.
Kreyenborg's four-cavity screen changer combines a large filter area with a fully automatic backflush.
In the V-type screen changer, the melt is guided onto four screen cavities. The melt is split into four melt streams at the entry, and after filtration these melt streams are brought together again in the heated steel housing.
Kreyenborg is based in Munster, Germany.
