  1. MRE Rations in All-Polymeric Pouches and why would we want to go there! Tom Dunn Printpack Inc. Atlanta, Ga

  2. Why do we wanna go there? • Look at current MRE packaging • Really look at current MRE packaging! • Look at current MRE logistics • Consider novel food processing techniques • Assess their impact on packaging requirements • Identify critical success factors for this packaging • Consider alternatives for achieving this mission! • Review results to date • Anticipate future development

  3. A look at current MRE packaging He that will not apply new remedies must expect new evils; for time is the greatest innovator.  Things alter for the worse spontaneously, if they be not altered for the better designedly.  ~Francis Bacon

  4. LENGTH Really look at current MRE packaging WIDTH DEPTH

  5. Foil Pouch Lamination: Entrees Puncture Resistance, Heat resistance Oriented PET Aluminum Foil Light, Oxygen, Water Vapor Barrier/ Stiffness Oriented BON Polyolefin Puncture Resistance Pouch Sealing / shock absorbance

  6. Process Packaging Store Transport Store Deploy MRE Logistics

  7. Novel Food Processes: Impact Factors

  8. Process/Packaging Impact

  9. Process/Logistics Impact Adapt the Packaging!

  10. Adapt the packaging to microwave sterilization!

  11. Plan of Attack: Packaging for MWS

  12. Tactics

  13. Light Barrier Results • Virginia Tech review of photodegradation chemistry of MRE foods • Organoleptic and nutritional values at risk • Wide spectrum (UV-visible light) of active harmful light energy • Virginia Tech development of lab model to assess light barrier effectiveness • Olive oil and yogurt as model foods • Hexanal as target indicator • Link hexanal generation to UV-Vis light absorption of packaging materials • Design light barrier in packaging materials • Opacified polymer layer(s) • Opacified adhesive layer(s) • Confirm effectiveness with accelerated shelf life assessments

  14. Figure A: Dielectric properties Carbon Black Carbon Black Clear 1 opaque adhesive Microwave Transparency Results • WSU adapted dielectric properties food method to flexible packaging • e’: ability of a material to store electromagnetic energy • e“: ability of a material to dissipate electric energy as heat • Carbon black • Limited FDA food-contact approval • Known microwave absorption

  15. Oxygen Barrier Results • Limited success with nanocomposites and multilayer coextrusions • Nanocomposites couple with MV energy • Coextrusions will play a role. (machine/material complexities slow down) • Available films and polymers have weaknesses • Moisture sensitivity • Coating durability

  16. Water Vapor Barrier Results • Simple polyolefins best MVTR providers • Strong thickness impact • Coatings the other alternative • High Barrier WVTR Coating durability issue • “Saran” Coating presents environmental negatives

  17. Other Results

  18. Oriented PET Oriented PET Aluminum Foil Coated PET Oriented BON Coated BON Polyolefin Polyolefin Pouch laminations: Foil v. Polymeric Barrier Coating

  19. Oriented PET Coated PET Coated BON Polyolefin Pouch laminations: Foil v. Polymeric Puncture Resistance, Heat resistance Light, Oxygen, Water Vapor Barrier/ Stiffness Puncture Resistance Pouch Sealing / shock absorbance

  20. Arrive where we started and know the place for the first time

  21. Future Developments/Packaging • On-pack Time & Temperature Integrator • Shelf life modeling of logistics factors • Sensitivity analysis for barrier levels • Contribution to shelf life of secondary packaging • Microwave interaction with polymeric chemistry • Within pouch-type/between process shelf life comparisons • Impact of packaging on nutritional factors over time • Cross process technology comparison • Foil- and Polymeric- pouches comparison • Failure analysis: packaging volatiles during HPP • Definition of Quality Plan for MWS pouches • Technology transfer to commercial applications
