Laboratory Cast Film Extrusion Lines
The supplier:
Hapro
Flat-die film extrusion equipment is used to produce cast film. The melt exits through a flat die, then is formed and cooled on rolls.
Hapro offers a standard laboratory version and a compact laboratory version. The difference between them is not the technology, but the scale, sample width and size of the forming unit.
