Extrusion

Extrusion is a continuous process through which parts of a fixed cross-sectional profile are made. Material is fed through a hopper into an extruder, essentially a rotating screw surrounded by a heated barrel, where it is mixed, melted and pumped through a die. The die gives the part its shape. From this zone you link to information on some of the more common extrusion methods, such as film, sheet, and pipe/profile/tubing

Recyclable All-PE Pouches: Sustainable Opportunity for Film Extruders

Sustainability and the Circular Economy are both a challenge and an opportunity to flexible packaging producers. Recyclable pouches based on all-PE multilayer structures, utilizing new resins and perhaps techniques like MDO or biaxial orientation, appear to be major contenders against glass, metal, and multi-material film structures.
