Better quality product and payback in one year on blown-film lines

That’s the claim made by Gneuss Inc. (Matthews, NC) for blown-film processors keen to integrate more reclaim or recycled material into their extrusion lines. The manufacturer of polymer filtration systems markets its SFXmagnus for these applications.

Stephan Gneuss, managing director at the company, says, “On blown-film applications, the return on investment for the SFXmagnus is usually around one year—and this is for retrofitting an existing line where the replacement of an existing screen changer has to be justified.”

One of the company’s recent blown-film customers, a processor of 3-layer polyethylene garbage-bag film, retrofitted an extrusion line with an SFXmagnus and reported it was able to increase the percentage of recyclate in its recipe from 25% to 45%. Another blown-film processor of single-layer packaging film was able to use up to 100% recycled material.
 
The SFXmagnus, like all of the company’s melt filtration systems, is based on the rotary disk system. Screen changes can be made with no need to stop processing. Because it is  process-constant, very fine filters can be used, leading to high quality film with tight tolerances. —[email protected]
