First time in Germany

The first 9-layer coextrusion line by Macchi in Germany has recently been delivered and installed at the premises of Duoplast, a leading producer of agricultural film. The line - configured with seven 55-mm extruders, two 65-mm extruders, a 500-mm die head and a BO Plus double station automatic winder - has a capacity of about 500 kg/h.

The line is designed for new products development in the agricultural field, load security stretch film applications and food barrier films, and will enable Duoplast to produce stretch films with even more efficiency, thinner layers and higher stretchability. The new line extends Duoplast’s portfolio of high-performance films based on recycled material and on polymers from renewable raw materials.

Furthermore, the line incorporates many of the most recent Macchi's technological developments, such as, in particular: an air recirculation system for a dramatic reduction in energy consumption; a micro porous inversion bar system for the specific production of sticky films; a fully automated system for unloading finished rolls; the "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 Duoplast development as far as functionalities, quality and production standards are concerned. Now we can use special polymers in each single layer. We can grant our customers 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”, explained Detlef Kaase, COO of Duoplast.
