Macchi plant for 9-layer film - First time in Germany

The first 9-layer coextrusion line by Macchi in Germany has recently been deliveredand installed at the premises of Duoplast, a leading producer of agriculturalfilm. The line - configured with seven 55-mm extruders, two 65-mm extruders, a500-mm die head and a BO Plus double station automatic winder - has a capacityof about 500 kg/h.

The line isdesigned for new products development in the agricultural field, load securitystretch film applications and food barrier films, and will enable Duoplast toproduce stretch films with even more efficiency, thinner layers and higherstretchability. The new line extends Duoplast’s portfolio of high-performancefilms based on recycled material and on polymers from renewable raw materials.

Furthermore,the line incorporates many of the most recent Macchi's technologicaldevelopments, such as, in particular: an air recirculation system for a dramaticreduction in energy consumption; a micro porous inversion bar system for the specificproduction of sticky films; a fully automated system for unloading finishedrolls; the "Macchi 4.0" system for production data exchange

“The new extrusion line, which fully comply withall most stringent Industry 4.0 requirements, is a fundamental component forfurther Duoplast development as far as functionalities, quality and productionstandards are concerned. Now we can use special polymers in each single layer.We can grant our customers higher load security and higher barrier propertieswhile using less material. The simple handling and the high safety standardsbring  high added value for ouremployees”, explained Detlef Kaase, COO of Duoplast.
