This technique uses air pressure to produce a transverse direction draw and a higher speed haul-off roll speed to provide a machine direction draw. Techno FLEX Blown Film lines for the production of multi-layer film 3.

The blown film extrusion process can produce magnificent arrays of products however. Extruder screw 70 mm ld 24 die diameter 250 mm and 300 mm gap 09 mm and 12 mm corona treatment wrapper 1600 mm working width. Given therefore a single screw machine is being described that has a screw of diameter 60 mm and a length of 24 screw diameters that is a LD ratio of 241.

The bottleneck in blown film extrusion lies in the cooling of the fast moving thin melt film It is important to understand that three elements of the blown film process are of first order importance to be able to produce near uniform gauge blown. Blown film extrusion is a continuous process and films of many sizes can be made by it by varying the rpm of conveyors and motors. This type of extrusion utilizes two or more extruders to melt and deliver a steady volumetric throughput of different viscous plastics to a single extrusion head die which extrude the materials in the desired form.

Technical system exercise to ensure nigner mm. Blown film extrusion is used for production of sheets and films of different polymers like HDPE LDPE PS and PE. The polymer is melted in an extruder and the hot melt is pumped through a die to form a thin-walled tube which is simultaneously axially drawn and radially expanded.

Coextrusion of blown film Coextrusion is the extrusion of multiple layers of material simultaneously. Blown film extrusion is the most important process for the production of plastic films ranging in thickness from 05 mm to as thin as 5 μm according to Butler 1. Mono-blown film lin in good working condition for processing LD and LLD-PE film width max.
