New coextrusion systems from Macro Engineering & Technology, Mississauga, Ont., feature a more compact extruder design with a small footprint that allows more space in the extrusion area and simplifies installation. The C-series of MacroPlast extruders was designed for coextrusion of films with seven or more layers utilizing a variety of polymers, including nylon and polyesters. All controls are mounted on the frame of each extruder and can be configured in different positions. The compact design and configurable control positions will accommodate a 13-extruder configuration, Macro says. The company now uses MacroPlastC extruders in all multilayer blown film, cast film, and bi-oriented shrink-film lines.
