  1. Begg & Co Thermoplastics Ltd. Creative Masterbatches & Raw Materials MouldPerfect in Thermoforming Applications Darren Wadsworth July 2006

  2. Case Study Thermoformed Meat Trays 27% Productivity Improvement PPCo Multi Layer Meat Trays Off-line thermoforming Benefits • Improved productivity cycle reduced from 7.5 to 5.9 sec • Less warpage (bottom of containers flat) • Improved trimming and quality Tc = 125 C Tc = 116 C Cycle Time (sec) Tray at 5.9 sec Tray at 5.9 sec with Mould Perfect

  3. Case Study Thermoformed Margarine Container PP Homo MFI 3 Margarine Container (9 g) In Line Thermoforming Benefits: • Improved productivity – cycle reduced from 19.1 to 20.8 cycles / min • Improved stiffness / top-load & easier stacking of parts. 9% Productivity Improvement Productivity (cycles / min)

  4. Case StudyThermoformed Lids PP homo / PP co Random Blend(75/25) Thermoforming Benefits • Improved quality, less warpage with flatter lids Shrinkage Isotropy Closer to 1 = Less Warpage Shrinkage Isotropy (MD/TD) Control Mould Perfect Control Mould Perfect

  5. Case Study Thermoformed Cups PP homo MFI3 (with 50% regrind) Drink Cups In Line ThermoformingBenefits • Improved productivity –cycle reduced from 21 to 27 cycles / min • Improved stiffness / top-load & easier stacking of cups. 29% Productivity Improvement Productivity (cycles / min)

  6. Case StudySheet Extrusion PP homo (with 35% regrind) Sheet extrusion (800µm x 670mm) Benefits • Improved productivity – improved output from 10.8 m/min to 12.5 m/min. 15% Productivity Improvement Extruder output (m/min) • This sheet was used to make the parts described on the next slide.

  7. Case Study Thermoformed Food Storage Containers PP homo (with 35% regrind) Thermoformed Sandwhich box Benefits • Improved productivity – cycle reduced from 2.6 to 2.3 sec • Improved quality – less warpage with Mould Perfect (on bottom of part) 13% Productivity Improvement Cycle Time (sec)

  8. Nucleation Agents cause warpage due to uneven shrinkage Case StudyThermoformed Lids Shrinkage Isotropy Closer to 1 = Less Warpage PP homo MFI 2 In Line Thermoformed Lids Control (non-nucleated) Nucleation Agent Mould Perfect Benefits • Improved quality – flat parts Shrinkage Isotropy (MD/TD) Nucleator Mould Perfect Control Nucleators Mould Perfect
