Blown Film Extrusion

Plastic bags, plastic wrap, shrink wrap are examples of plastics made from Blown Film Extrusion. The blown film extrusion process consists of an extruded tube of molten thermoplastic that is inflated to several times its initial diameter, forming a very thin tubular product which can be used as is or slit which forms a flat film.
