Read MoreOptions for Surface Treating Extruded Film
Traditionally, film extrusion lines utilize a metal electrode and covered roll configuration. However, there are exceptions. Some companies choose a Bare Roll system to eliminate any roll covering concerns. Fixed or segmented applications? For simple applications that do not require lane treating, a fixed width metal tube electrode provides adequate treatment levels. For demanding fixed width applications,…
