EXTRUSION AND COMPOUNDING AT NPE: Flexibility, Speed, Quality Rule the Day
Extrusion processors need more—of everything—to compete. And suppliers responded in force in Orlando.

EXTRUSION AND COMPOUNDING AT NPE: The Word Is ‘More’
As in speed, power, quality, flexibility, layers, and efficiency. Those are the trends across all extrusion processes.

EXTRUSION: Another Way to Extrude PET Without Drying
A planetary-roller section allows efficient degassing.

Extrusion/Compounding at K 2013: Having It All
Extrusion processors no longer need to chose among speed, quality, and flexibility, based on exhibits at K 2013.

K 2013 Preview: Extrusion, Compounding, Recycling
Across all extrusion technologies, expect to see new standards in speed, quality, flexibility, and efficiency in both energy and material usage.

IML Groundbreaker Adds Sheet Extrusion
In-house sheet production allows Tech II to vertically integrate to hasten product development, control costs.

New Option for No-Dry PET, PLA Sheet
New twin-screw system is based on a conical design.

Packaging Powerhouse Does It All
Materials formulation, cast and blown film extrusion, sheet extrusion, printing, and laminating come under one roof at this processor.

Extrusion & Compounding at NPE: Advances Push Efficiency Envelope
Blown film towers may have been scarce, but there was no shortage of new technology aimed at helping to make extrusion processors more profitable.

Extrusion & Compounding at NPE: More Output, More Flexibility, Less Energy
There won't be many blown-film lines running, but there is still much in the way of innovation going on in extrusion and compounding.

EXTRUSION: Nine-Extruder Sheet Line For Yogurt Cups
A new customized nine-extruder, five-layer sheet extrusion system for production of multi-colored, striped sheet for thermoformed HIPS yogurt cups is said to be one of the most unusual and sophisticated packaging sheet lines on the market.

Rolls and Cut Sheet
Whether producing mono- or multi-layer sheet, many sheet extrusion systems produce rolls of finished sheet, or stacks of sheet that has been cut-to-length.

Sheet Extrusion Line
A sheet extrusion line consists of an Extruder (single or twin screw), equipped with a Screen Changer and a Gear Pump, followed by a Static Mixer (sometimes feeding a Coextrusion Feedblock that is preceded by one or more additional extruders sets as described above), feeding a flat sheet die.

K Show Report: Nanos Are The Rage
Flat film and sheet toolmakers are focusing on technologies for nanolayer systems.

Extruder and PLA regrind receiver

On-Site: Green Business Is Good Business for Fabri-Kal
"We tend to jump on things early," says John Kittredge. "F-K has been a pioneer in a number of things. Our earliest example was converting HDPE margarine tubs to ABS. After that we were a leader in thermoforming polypropylene, and then APET." Now it's PLA biopolymer.
