Extrusion process
Plastic melt is extruded through an annular slit die, to form thin walled tube
Air is intruduced in the centre of the die to blow up the tube like a balloon(IBC)
Air ring blows onto the hot film to cool it(outside and inside the tube)
The tube passes through nip rolls where is flattened
Collapsed tube is taken back down the extrusion tower via more idler rollers
On winder the tube or film is wound into rolls | |
