2. Case Study Thermoformed Meat Trays 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 Cycle Time (sec) 27% Productivity Improvement Tc = 116 C Tc = 125 C 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. Productivity (cycles / min) 9% Productivity Improvement

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

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

6. Case Study Sheet 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. Extruder output (m/min) 15% Productivity Improvement 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) Cycle Time (sec) 13% Productivity Improvement
