Macchi has recently delivered and installed the first 9-layer coextrusion plant to the company DUOPLAST AG, a leading producer of agricultural film in Germany. The line, configured with seven extruders 55 mm, two extruders 65 mm, 500 mm die head, BO PLUS double station automatic winder, has a capacity of about 500 kg/hr.

The line is designed for new products development in the agricultural field, load security stretch film applications and food barrier films. Macchi 9-layer enables DUO PLAST to produce stretch films with even more efficiency, thinner layers and higher stretchability; it strengthens the sustainability approach, providing DUO PLAST with the unique capability to extend their portfolio of high-performance films based on recycled material and on polymers out of renewable raw materials.

Furthermore, the line incorporates many of the most recent Macchi’s technological developments, such as but not limited to: • New air recirculation system for a drastic reduction in energy consumption • New micro porous inversion bar system, specific to produce sticky films • New fully automated system for unloading finished rolls • New “MACCHI 4.0” system for production data exchange “The new extrusion line, which fully comply with all most stringent Industry 4.0 requirements, is a fundamental component for further DUO PLAST development as far as functionalities, quality and production standards is concerned. Now we can use special polymers in each single layer. We can grant our customers a higher load security and higher barrier properties while using less material. The simple handling and the high safety standards bring high added value for our employees”, explains Detlef Kaase, COO of DUO PLAST AG.
