  1. 1. February, 2014 2/25/2014
  2. 2. How Does IQF film begin? IQF film begins as LDPE/LLDPE plastic resin pellets
  3. 3. Film Fabrication Extruder Extruder The function of an extruder is to melt the polymer, mix the polymer and other additives, and deliver a homogeneous melt at uniform pressure and output to the die by the application of heat and shear. VII-6b
  4. 4. Screw Hopper Thrust Bearing Assembly Rotary Joint Gearcase Powder Seal Cooling Water Machine Base Inlet Manifold Safety Shroud Stockscrew Cast Heaters Cylinder Feed Throat Cylinder Support Pressure Gauge VII-7b
  5. 5. Film Fabrication Blown Film Process 4 1 2 3 VII-4b
  6. 6. Polymer orientation during film fabrication BUR=bubble diameter / die diameter Side View Front View Before the polymer cools, the polymer chains are stretched 2.6 times in the cross direction and 8.5 times in the machine direction. The thickness is reduced 22 times. This orientation or stress is frozen into the film. 8.5” 0.0025” 2.6” Polymer exits the die and is in a relaxed state 1” 1” 0.055” 6
  7. 7. Determination of BUR and Layflat Draw Down Ratio (DDR) = Die Gap Gauge
  8. 8. W & H Technology Will Be A Catalyst To Our Success
