Extrusion of blown film Polyregion

Coextrusion is the extrusion of multiple layers of material simultaneously. This type of extrusion utilizes two or more extruders to melt and deliver a steady volumetric throughput of different viscous plastics to a single extrusion head (die) which extrude the materials in the desired form. The layer thicknesses are

Extrusion Wikipedia

Extrusion is a process used to create objects of a fixed crosssectional profile. A material is pushed through a die of the desired crosssection. The two main advantages of this process over other manufacturing processes are its ability to create very complex crosssections, and to work materials that are brittle, because the material only encounters compressive and shear stresses.
