Blown Film Extrusion Process

Extrusion Process Step-by-Step

  3. Polymer is moved through extruder by screw rotation.
  4. Pellets are melted through sheer energy and electrical heat.
  5. Molten polymer is pumped through die and shaped.
  6. Polymer is cooled as it is formed into a bubble.
  7. Bubble is flattened out to desired thickness and width and then wound into rolls.
