Blown Film Extrusion

A Global Leader in Blown Film Technology

Always a step ahead: Our die head series X offers very short rinsing time and thus provide the quickest program change on the market.

As the pioneer in the MDO technology, Hosokawa Alpine has been setting new standards for the blown film technology. We are not just the first manufacturers to develop and launch this technology, but we have also made consistent efforts to enhance it further.

Thus, the unique  TRIO technology (“Trim Reduction for Inline Orientation”) provides significant material savings in edge trimming, and the vacuum technology optimizes flatness and processability significantly.

Our model for perfect film quality:

  • Tailored solutions
  • Optimally coordinated components
  • Comprehensive service ranging from planning to complete installation on site
  • Over 70 years of experience and innovating
  • Mature “made in Germany” technologies

Test center for research and film development

Customized designs as per your needs

You already have a specific idea about the composition or would like to develop it together with raw material manufacturers and our experts?

The Hosokawa Alpine test center in Augsburg (Germany) offers you all that and more. The test center over an area of 1000 m2 has the latest coextrusion and MDO lines with up to eleven layers to facilitate the series of tests you would like to perform.

The team in our test center has comprehensive know-how and is able to offer our customers optimum consultancy and support in their tests.

  • Live demonstrations of blown film lines (1 to 11 layers)
  • Live demonstrations of MDO film orientation lines
  • Application tests for customer applications
  • Test laboratory with modern test equipment


We set standards

For more than 70 years

High-performance components, one-of-a-kind technology and innovative ideas are the guarantee for process stable and economical blown film lines. Decades of experience and our competent advice make the difference.

We are the partner for your film solution. Since 1950. In order to offer the best solutions to our customers, we have been constantly working on improving our systems and lines. Day after day. 



The new MDO vacuum technology further optimises flatness and processability of oriented films



The new Select extruder for energy-saving extrusion at low melt temperature is presented.


Process visualisation ExVis 5.0


Introduction of ExVis 5.0 with an even more intuitive user interface.

MDO 04


The new MDO 04 film orientation line is presented.


First High Barrier Film Day in Augsburg  – Introduction of innovative 11-layer packaging films.
Launch of ExVis 3.0 with numerous new features.

Die head


K Show October 2013 Hosokawa Alpine introduces the first 11-layer X-die for the ultimate performance in the production of barrier films.


TRIO system (Trim Reduction for Inline Orientation) is introduced. The revolutionary thickness control system reduces the edge trim waste during the inline orientation process, thereby ensuring excellent flatness of the film.


ExVis 2.0 is presented.

Introduction of the cooling ring-Generation VX newly developed by Hosokawa Alpine (adjustable in height, with 3 discharge levels) for markedly increased output rates through even more efficient cooling of the film bubble.


Hosokawa Alpine presents the new AWS and AWD winders.


The first lines for 9-layer high barrier films are produced.


Under the designation "Generation X" Hosokawa Alpine presents a new series of the die heads in monoblock design, in addition to directly driven extruders which produce outstanding film qualities.


The first Hosokawa Alpine lines for 7-layer films are produced. These lines open up entirely new possibilities to the user in terms of film composition and design of the film properties.


Hosokawa Alpine sets new standards in process visualisation with introduction of the "ExVis" extrusion visualisation.


The first Hosokawa Alpine MDO orientation lines are delivered. These allow specific modification of the mechanical properties of the films and savings in raw materials.


The film thickness is precisely controlled and regulated using the new POS profile optimisation system.


Presentation of the IBC tube internal cooling. The increased cooling performance increases output by 50 %.


The first oscillating extruder HS 35/12L/D is marketed. Whereas formerly the winder rotated in order to uniformly distribute thickness errors, the extruder was now reversed. Handling of the finished, heavy film roll was made considerably easier as a result.


The first blown film line with a high speed, adiabatically-operating, type H screw press designed for "strenuous operation" is developed.


The KSE 45 screw extruder capable of processing all the thermoplastics known at the time is introduced.
