Mono-blown film dies are available with axial or radial spiral mandrel distributor, depending on application and expandability.
Multi-layer dies for 2 up to 13 layers are suitable for many different numbers of layers. For these processes, Collin provides dies with radial spiral mandrel distributor and matching mandrels and female dies.
The retrofit between different layers is easy and quick – e.g. from 3 layers to 5 layers.
