Jay Visual Packaging uses stretchable ink
A special stretchable ink allows Jay Visual Packaging Inc. to print roll stock before it gets thermoformed.
The company in Lyons, Wis., has used the technology to make packages for Oral-B toothbrushes and a Reader's Digest promotion.
Putting a label on the sculpted surface of the small toothbrush package would have been difficult, since it has very little flat space.
For the Reader's Digest project, opaque high-impact polystyrene was preprinted on roll stock before it was formed into a clamshell.
The magazine used the package to hold keys as part of direct-mail sweepstakes.

TPS Thermoform Parts offers clamp frames
Beaverton, Mich.-based TPS Thermoform Parts Supplier has added a line of aluminum pin bar, channel and extruded aluminum clamp frames for cut sheet thermoforming machines.
The frames are custom-made using a modified Knu-Vise cylinder, with a longer stroke and wider bore than standard aluminum clamp frame cylinders.
According to TPS, the larger bore allows a wider spacing of the cylinders than competing frames.

PTI coextrusion line runs 7 layers of sheet
Processing Technologies Inc. of St. Charles, Ill., has built a coextrusion sheet line that can run up to seven layers. The line is designed to run with an in-line thermoforming machine.
PTI supplied the line to a large Midwest packaging company, which it did not identify. The line produces high-barrier polypropylene/ethylene vinyl alcohol-based sheet for containers.
The line includes five PTI Trident Series extruders — a main extruder with a screw diameter of 6 inches, one 3.5-inch, two 2.5-inch and one 2-inch extruder.
Coextrusion of up to seven layers is done with a Cloeren Inc. multimanifold die combined with a coextrusion feedblock. Cloeren is based in Orange, Texas.
The 6-inch main extruder and one satellite extruder are equipped with melt pumps for thickness uniformity and static mixers for better thermal homogenization.
A control system monitors all temperature zones and drives. It also does die-bolt control for automatic control of sheet thickness.
The line comes with PTI's J-Stack, a three-roll cooling and polishing stack.
A primary nip is installed at a 40-degree angle to the centerlines of the extruder, allowing for a close approach and a reduced air gap. That also helps in processing materials with a low melt strength, which tend to sag when entering the nip on a horizontal layout.
The other two rolls are positioned vertically.
PTI's Auto-Gap servo-hydraulic roll positioning system automatically sets and controls the nip roll gap.

Plastimach to sell Maac's Comet line
Maac Machinery Corp. is selling its re-engineered Comet line of thermoforming machines exclusively through Plastimach Corp., an equipment dealer in Valley Cottage, N.Y.
Maac, of Carol Stream, Ill., bought Comet Industries Inc. in 1997.
The new Comets are fitted with microprocessor controls and new safety features. The single-station and rotary thermoformers can handle sheets as large as 5 feet by 8 feet, giving a draw of up to 26 inches.
Prices start at $85,000 for a single-station machine and $129,000 for a three-station rotary that forms sheet measuring 4 feet by 6 feet.

Uniloy helps design self-heating can
Uniloy Milacron says it played a key role with the new self-heating can developed by Ontro Inc. of Poway, Calif.
Ontro's container begins heating beverages or soups when the user removes an aluminum disc at the bottom of the can.
Uniloy Milacron, of Manchester, Mich., developed the mold and prototypes and supplied blow molding machines when Ontro wanted to commercialize the can. A key advantage was that Uniloy's six-layer BW 3000DE shuttle blow molding machine offered accuracy and repeatability, required to produce the intricate structure. The shuttle design also offered quick mold changes for the initial testing and limited production.
Ontro's six-layer polypropylene can comes with an internal heat-generation cone filled with crushed limestone. When the disc is removed, water interacts with the limestone and generates heat. Contents of the can reach 80 degrees F after five or six minutes and stay that hot for about 20 minutes.
Original designs called for the two main components — the heating cone and the outer shell — to be produced from two different molds. During product development, Uniloy engineers suggested molding the two components from a single parison. The top half of the parison would be the shell of the outer container, and the bottom half is the cone. After molding, the cone is removed and inserted into the shell, then both parts are welded together.
The BW machine's parison control held tight wall-thickness tolerances and handled the correct pinch-off at the tip of the cone.
Ontro is using the machine to mold containers at its pilot plant in Poway.

ADS touts machine's PET bottle capacity
At a Paris trade show in November, the French blow molding press maker ADS displayed a machine it says produces 1,600 PET bottles an hour.
The stretch blow molding machine, dubbed G62-S, can run bottles up to 10 liters in capacity. ADS is claiming it is the only equipment supplier so far to present a two-stage machine that can blow bottles that big.
The company is aiming the G62-S at the mineral water and edible oil markets.
At the Emballage 2000 trade show, ADS was blowing 8-liter bottles.
The company is based in Cergy-Pontoise, France.

Manifold reduces shear-heat history
Electra Form Industries, a unit of Wentworth Technologies Co. Ltd., has developed the Exstream hot-runner manifold for PET preform molding.
Exstream addresses concerns by preform molders and bottlers about acetaldehyde (AA), a byproduct of heat history in PET that can alter the taste of a container's contents. The manifold was designed to reduce the shear-heat history.
Electra Form conducted manufacturing trials, using the head-space method, on a 48-cavity preform mold. Results showed an average AA rate of 1.0 microgram per liter over the 48 cavities. The maximum value was 2.2, a minimum of 0.58 and a standard deviation of 0.43 micrograms per liter — all well below the industry standard.
Electra Form of Vandalia, Ohio, offers Exstream on all of its molds. The company also sells a retrofit package for existing molds.

Q.M.I. develops blown film punch
Q.M.I. Inc. of Pryor, Okla., has developed a machine that punches holes on blown film as it moves by as fast as 350 feet per minute.
Q.M.I. said the Vent Punch System punches the pattern at the proper spacing no matter how fast or slow the web moves, thanks to an optical encoder linked to an on-board computer. The machine punches holes ranging in diameter from an eighth of an inch to seven-sixteenths of an inch. A personal-computer-based controller stores up to 54 hole patterns.
