OVERVIEW:
Film Extrusion

filmEXT.jpg

Film is divided into two subcategories: cast, or flat film; and blown film. In the former, hot plastic is extruded through a flat, slit die onto a polished chill roll where it is quenched, pulled to a second set of rolls to cool the other side, then wound. In blown film, plastic is extruded into a cylindrical die, then inflated to form a bubble, which is ultimately cooled and collapsed. Films can be either single or multi-layer. Most are based on polyethylene. Bags are one primary example of film extrusions.
