The working principle of a Film Extrusion Line involves feeding plastic granules or pellets into the hopper, where they are conveyed to the extruder barrel. Here, they are heated, melted, and mixed by a rotating screw. The molten plastic is then filtered and pumped through a die that shapes it into a thin film. This film is rapidly cooled and solidified, often through chilled rollers or a water bath. In some processes, the film undergoes biaxial orientation for enhanced strength and properties. Finally, the finished film is either wound onto rolls or cut into sheets, ready for various applications in Packaging, Packaging, Medical, Construction and other Specialized industry
