From the die a tube-like intermediary product emerges, which is transformed into a bubble by blowing, pulled off by a mechanism, and forwarded to the winding equipment. The basic processes of film blowing consist of plasticating, production of the parison, blowing and cooling.
The blown film manufacturing process involves the transformation of plastic resins into thin, continuous films through the use of specialized machinery. It is a complex and intricate process that requires expertise and precision to ensure the production of high-quality films. The first step in blown film manufacturing is extrusion.
The objectives of automation of film blowing processes are: -- to maintain the thickness and the width of thefilmwithout manual interference and to reduce material consumption, -- to reduce start-up and product change times, -- to optimize utilization of the equipment and to increase production output.
The film bubble is blown with air under 1 to 10 kPa pressure through the die core, while the thickness of the film is adjusted by controlling the air blow and with the aid of a pair of traction rolls with adjustable velocity.
The mechanical properties of blown film are nearly uniform in both directions as a result of biaxial orientation, and this is the reason for producing flat film by the film blowing process. The two main parameters of this process are the blow ratio (or blow-up ratio), BR (or BUR), and the machine-direction draw (or drawdown) ratio, DR.
About 20% of the dies used in film blowing fall into the category of dies with distribution channels, or troughs, 70% in the coreholding category and 10% in the spiral type. Film thickness deviations and variations may be substantially reduced by using a rotating die type.

Film blowing machines are specialized equipment used to extrude plastic materials into thin films. The process involves melting and shaping the plastic resin, which is then blown into a bubble-like structure and cooled down to form a film. This film can have various thicknesses, widths, and properties, depending on the desired application.
Lab Blown Film Extrusion Three layer co-extrusion film blowing machine: The blown film process begins with the extrusion of a plastic resin, typically polyethylene, into a molten state. This is achieved by heating the resin in an extruder, which is a long, heated barrel with a rotating screw inside. Circular Die: The molten plastic is then forced through a circular die, which shapes the ...
