Introduction [] Blown film extrusion is a technology that is the most common method to make plastic W films especially for the packaging industry The process involves extruding a tube of molten polymer W through a die and inflating to several times its initial diameter to form a thin film bubble This bubble is then collapsed and used as a lay-flat film or can be made into bags Flow Lines in Blown Film What was the problem? Flow lines appearing in blown film! The customer saw lines appearing around the circumference of their blown film bubble as represented by the image shown below They did not know what was causing the problem and more importantly how they could fix it They were under pressure to find a solution

BLOWN FILM LINES A blown film line is quite different from a flat film line In a blown film line a tubular film is extruded vertically upwards as shown here The tube expands due to internal air pressure The ratio of the bubble diameter and the die diameter is called the blow-up ratio Typical blow-up ratios used in LDPE film extrusion for packaging are in the range of 2 0:1 to 2 5:1 When

7 Layer Co-Ex blown film lines meets a majority of the industry's critical packaging development needs 7 layer co-extruded blown film line is even used for complex packaging solutions with a maximum output of 1500 kg/hour and lay-flat width ranging from 1500mm to 4500 mm to produce both barrier films and non-barrier films

The blown film process can produce a wide range of film sizes from the same die • Blown films provide a better balance of properties between the machine and transverse directions • Blown film lines are used to make shrink wrap films • Blown film lines require lower melt temperatures • Blown film towers require large vertical heights • Bags produced by blown film operations
