Poly Propylene Blown Film Plant

Blown film extrusion is the most common process for the production of continuous films that are used primarily for packaging. The first step in the process is to melt the plastic in the extruder, the molten polymer then enters an annular die head and is formed into a tube of plastic material.Blown films, also commonly known as tubular films, are created by extruding plastic through a tubular-shaped die and then stretched and blown with air to create a very thin-walled film. Polyethylenes such as LDPE, LLDPE and HDPE polymers are common resins that are used to create blown films.
