  1. Overcoming Process Issues Using Sustainable Visual Packaging Materials – Sealing John Murphy October 6th, 2009 AVPM

  2. Sustainable Material Choices • Heat Sealing to Aqueous or Solvent coated cards • APET • RPET • RF Sealing • PETG • Utility Grade PETG • Plastic-to-Plastic Heat Sealing • PETG • Utility Grade PETG

  3. Considerations when converting to PET • Sealing Parameters • Sealing parameters are much different from PVC • One process recipe or setting will not fit all • PVC and PET settings are considerably different • Much smaller window for success • Temp • Dwell • Pressure • Validation criteria will change

  4. Considerations when converting to PET • Blister specifications are critical to sealing success • PET processing is much more like medical • Process control of critical blister attributes • Consistency run to run • Feedability • Design

  5. Considerations when converting to PET • Sealing Equipment • Relatively unchanged • Machine maintenance and upkeep is necessary • Cycle speeds can be comparable • Seal Tooling • Feedability – PET tendency to block • Tooling maintenance and upkeep is necessary • Heat block – accurate thermocouple readings

  6. Successful PET Sealing • Choosing the correct material • Blister design for feedability and control of key sealing attributes • Thermoforming process control • Card and card coating • Machine and seal tooling maintenance • Process validation
