Air Ring. Extruder. Side. “Sow Belly”. Hot side becomes thinner before freezing. Page 11. Single Peak TD Gauge Variation. Linear Plot. Collapsing Frame. Production steps: extrusion, printing, embossing, welding, recycling Air ring blows onto the hot film to cool it MD (machine direction). In blown film extrusion, molecular orientation of the polymer is achieved in both machine and transverse directions, yielding a film with biaxial properties.PDF | On Dec 19, 2012, John Vlachopoulos and others published Blown Film Dies machine and transverse directions to have even MD and TD ?lm properties. For example, some additives are designed to aid processing by reducing viscosity while others may have a detrimental effect on extrusion machinery by Three Layer ABA Blown Film Machine 30% Stronger Film. 50% Cost Saving. 60% CaC03 Added, 100% Recycled Material Used The A-B-A blown film machine consists of The elements of the process (Figure 1) in- clude the resin pellets which are fed through a hopper into an extruder. Here, heat and friction convert the pellets
