LLDPE Mono Layer Blown Film Plant

Introduction of Blown Film Plant:- Blown Film Plant is a technology that is the most common method to make plastic films, especially for the packaging industry. The process involves extruding a tube of molten polumer through a die and inflating to several times its initial diameter to form a thin film bubble.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.The blow up ratio is simply the ratio of the final diameter of the tube relative to the die diameter. The amount the film is oriented in the machine direction is controlled by the draw down ratio (DDR), which is simply the ratio of the thickness of the extrudate exiting the die to the final film gauge.
