A COMPLETE RANGE OF HIGH PRODUCTION AND HIGH QUALITY FILM LINES

The HDPE extrusion process requires specific technology. Superior quality physicals and optical properties can be obtained running the bulk of today’s polyolefins using low neck bubble configuration and technically standard extrusion screws and film dies. In comparison, HDPE processing requires that specific attention be paid to processing parameters and operating conditions. These crucial details will make the difference between simply changing raw materials in an existing line or changing raw materials and producing the high quality films that converters demand. Macchi has set out a range...

1 2 3 The resulting production quality is remarkable. A film line equipped with an IBC system can obtain production capacities of 1.3 kg/h for each mm of die lip diameter. This equates to approximately 22.5 lb./in of die circumference. A 250 mm (10”) ø die lip can produce 325 kg/h or 715 lb./hr. The distinctive design of the extrusion screws combined with a section of forced feed for high production and passage of HDiiPE can lead to excessive pressures and high erosion and abrasion circumstances. The use of specific materials for these components allows for a long production life span and...
