Laboratory extrusion line " multilayer film on chill roll"
This extrusion line is designed to achieve the development of thermoplastic multilayer,multimaterial films.
The material is extruded by 3 extruders separately, it is then took into the coextrusion container to produce a film or a sheet made with 3 to 5 layers of stacked materials, ABCBA, ABA or ABC, which is ithen calendered and rolled.
Characteristics:
- the output axis of the die head is in vertical position to allow a gravitational flow of the material on the lower roll
- linear air flow to flatten the film on the roll
- temperature of the roll controlled up to 160 °C
- film can be cut and rolled by a tangent winder
