The installation of a six-inch Davis-Standard extruder and line upgrade has enabled Mid South Extrusion in Louisiana, USA, to improve ouput while delivering a broader range of HDPE processing options.

Mid South, a supplier of converting and process films for industrial packaging markets, has upgraded an existing blown film line that has been in continuous operation for nearly 30 years.

The larger MAC extruder, along with a new feed screw, screen changer and control system have enabled the firm to boost processing rates and options for a range of HDPE, LDPE and LLDPE films on an existing line while minimising downtime. The project took around six months to complete and Mid South chose a smooth-bore extruder to allow flexibility for a wider range of materials.

Mike Henagan, executive vice president of operations at Mid South, said: “We have a strong history of infrastructure reinvestment and are always looking to make operational improvements. Projects like this have a very short return on investment and open the door to greater opportunities. The extruder and upgrade decisions were based on improved performance, quality and material selection.

“Davis-Standard is the only extruder manufacturer we trust for smooth bore technology for HDPE. Most manufacturers only offer groove feed. We also appreciate the timely delivery and installation, which allowed us to avoid production conflicts.”
