Blown Film Extrusion Machines

The Blown film extrusion lines are used to extrude plastic films for flexible packaging industry.
The process begin commonly through the melt of the granulates into an extruder and pushed through a circular die modeling it in the form of a tube. Subsequently This tube is carefully inflated and simultaneously cooled in its interior and on the exterior surface through the use of an air ring. A set of collapsing guides are then used to collapse the bubble into two, more defined, layers within closer proximity, a series of nip rollers flatten the layers together to form a two-layered plastic film that is then wound onto a cylindrical roll for packaging purposes.

Blown film extrusion is also versatile and able to manufacture a variety of single or multi-layer films with a range of film thickness and width. Raw material most used are low density polyethylene (LDPE) and High density polyethylene (HDPE).
Film produced with this kind of line have most applications from film for bags, to shrink film, lamination film, stretch hoods, PE film for packaging, barrier and many others.

The principal advantages of manufacturing film by this process include the ability to:

  1. produce tubing (both flat and gussetted) in a single operation;
  2. adjust the film width and thichness by control of the volume of air in the bubble, the output of the extruder and the speed of the haul-off;
  3. eliminate end effects such as edge bead trim and non uniform temperature that can result from flat die film extrusion;
  4. capability of biaxial orientation (allowing uniformity of mechanical properties);
  5. blown film extrusion can be used for the manufacture of co-extruded, multi-layer films for high barrier applications such as food packaging.
