About Addex
Addex Inc. was founded in July 1989 by Bob Cree and Rick von Kraus and entered the blown film industry with the first microprocessor-based Internal Bubble Cooling (IBC) control, later the first all-digital IBC. Through the 2000s Addex built complete air-cooled blown film lines — 4.5" single-screw extruders with smooth-bore or groove-feed barrels, IBC dies, automatic air rings and gauge controls — from its Stoughton, Massachusetts plant, before consolidating to Newark, New York in 2015–2016 and narrowing its focus to bubble cooling and control technology.
Today Addex is known for its EGC automatic profile control, Digital IBC controls, LFR and MGC dual-flow air rings, and the patented Intensive Cooling air ring, which sits down on the die and raises output 10–15% or more on both monolayer and barrier lines. The company holds more than 20 U.S. patents. Windmöller & Hölscher Corporation acquired Addex effective August 1, 2025; it continues to operate under its own name with a focus on the U.S. and Canadian markets.
On the used market, Addex appears two ways: complete 4.5" blown film lines built in the 2000s and early 2010s (often paired with Techflow dies, Decatex haul-offs and Macro winders), and Addex IBC and air-ring retrofits fitted to lines from other builders. Meadoworks lists both, with photos, component-by-component specifications and inspection visits arranged.

Frequently Asked Questions
Does Addex still build complete blown film lines?
No. Addex built complete air-cooled blown film lines through about 2016, then consolidated to Newark, New York and focused on bubble cooling and control technology - IBC controls, auto-profile air rings and Intensive Cooling. Used Addex lines from the 2000s and early 2010s are still common and well supported.
What is Addex IBC?
Internal Bubble Cooling circulates chilled air inside the film bubble and controls its size with sensors and a servo valve, raising output and tightening layflat control. Addex introduced the first microprocessor-based IBC control in 1989 and the first all-digital IBC in the early 2000s; Addex IBC units are frequently retrofitted onto other builders' lines.
What should I check when buying a used Addex blown film line?
Confirm the extruder screw diameter and L/D, whether the barrel is smooth-bore or groove-feed, and the drive motor rating; inspect the screw for wear. On the die and tower check the IBC plumbing and sensors, the air ring and its controls, and the oscillating haul-off. Verify the winder and slitter widths match the die and layflat. Meadoworks provides photos, video and inspection visits on the Addex lines we list.
