Performance BiB Transport Work Group Meeting Düsseldorf 19.3.07

1. Performance BiB Transport Work Group MeetingDüsseldorf 19.3.07 Introduction Laura West

2. Agenda

3. Objectives as of Nov. 2005 • Test parameters materials • Gas detectors for container selection • Naphthalene threshold • Models for transport simulation • Temperature and humidity during transport 6 Analysis of barrier properties of used materials

4. Status on Test parameters 2005-2007 • EU legislation is getting stricter • 2002/72/EC + ammendments (e.g. 2005/79/EC and 2004/19/EC) (plastic materials and food) • CIR 9312 of 16.5.2006 (materials and objects) • Reg. 1935/2004 (materials) • Announcement 426 of 10.5.06 (materials + food stuffs) Responsibility now lies with any distributor of materials for contact with food stuffs if contact is just remotely foreseeable • REACH is being implemented (2007) • General awareness is raised, and ingredients are removed from the market • Various food safety projects funded by the EU The entire matter is thoroughly being looked into by the EU - where the legislative power lies - and therefore has a lower priority in Performance BiB

5. Status Gas detectors for Contaminants • Aim is to develope a barrier which excludes contaminants • We continue to see problems with contaminants – not only naphthalene • Concentration of contaminants extremely low and hard to measure • Gas detectors often not very specific Therefore this has not had high priority

6. Status on Models for transport simulation • Tough task; • Hapag-Lloyd has been indicating figures describing enormous power, e.g. • 250 rolling movements/hour • Movements in extreme conditions up to 30° • 20 m fall in 20 seconds • Praxis tests under real conditions are still the way tests are done • Braid – flexitankproducer - has been invited to join our group

7. Status °C and RH during transport / transit • Some work has been done by V&S / Hillebrand • In general, shipping appears to be a smaller problem than land transport / transit • Some work has been done by Gilles Doyon, Canada • A number of group members is particularly interested in these aspects (but may not be present here today) • More must follow – Doyon suggests introducing GPS • Evaporation trial V&S, running

8. Status Barrier properties used materials

9. Future grouping of objectives I

10. Future grouping of objectives II

11. Future work in sub-groups All groups: • Systematic analysis – risk identification • Systematic proposal of solutions – risk management • Systematic sampling and analysis of wines and packagings • Proof, evidence and indications • Photographic, empirical and research records • Publication 2008

12. Method: Risk identification

13. Future group: Barrier properties • Analysis of used barriers • Evaporation trial • Flexcracking of laminated / folded foils • 2 barriers – EVOH + aluminium • New barrier materials • Lamination of aluminum • Nylon • Nanotechnology

14. Future group: Analysis of used barriers

15. Presently: Evaporation trial V&S

16. Future Work Group Flexcracking • Work mainly done by Giles Doyon • Work done by film and bag producers • Can anyone supply data?

17. Two Barriers and Nanotechnology • Experience, anyone?

18. Future focus: Exposures and contaminants • Information from shipper: Container paints always contain naphthalene – new containers therefore worst • Other possible sources: • Contamination in container from previously transported goods • Container floors – MUST be treated prior to fitting into container • Container paints contain naphthalene • Fumigation of containers • Article from Soren Gronlund • Dutch Study (Amsterdam) available on the internet; link available from Laura West • Glue from flexitank valves? • Dog use for sniffing containers / products?

19. Future focus: Transport conditions • Temperatures • Time and use of GPS • Humidity – as above

20. Movements during transport (mainly train and high sea) • Vibrations • Stop & go • Sea • Mechanical properties of bag – strengths • Development of tank

21. Work groups • GO!
