1. Understand the product’s stability
• Acceptable temperature range, allowable excursions (e.g. 2-8°C storage, 0-20°C for 48hrs in transit)
• Thermal mass (e.g liquid volume, lyophilized, primary pkg)
• Load configurations (e.g. min/max, secondary pkg.)
• Value of product • Other considerations, humidity, fragility

Product stability AND regulatory requirements define transit temperatures and allowable excursions for distribution
An example from one company for its’ US distribution of a temperature sensitive biopharmaceutical:
Temperature range for shipment in US:
2-8°C; allowable excursions 0-20°C for 48hrs in transit
Questions:
• Are wholesalers and distributors exempt from these requirements for the same product?
• Do mfg’s give them product distribution temperatures & excursion limits?

• Room Temperature: CRT 20-25°C• Cool: 8-15°C • Refrigerated: 2-8°C• Frozen or Refrigerated: < 8°C• Do Not Freeze: > 0°C• Frozen: < -20°C (some must protect from CO2 )• Cryogenically Frozen, CO2 or LN2: (-70° or -180°C)

Thermodynamics and Their Influence on Packaging Performance

Cold Chain Packaging Objective:
Temperature Maintenance During Transport
Primary Issue: transit environment that is unpredictable, uncontrollable and relatively unreliable
Industry Practice: design and qualify commonly available insulated containers and refrigerants under the temperature extremes measured in the companies’ transit routes

Shipping Performance is Based On:
Container Insulation (type, construction, wall thickness, size)
Refrigerant/Temperature Stabilizers
Ambient Exposure
Product Mass (thermal heat capacity of load)
Staging (temperatures of all materials prior to loading)

Conduction is the process by which heat energy is transmitted throughcontact with neighboring molecules. Some solids, such as metals, are good conductors of heat while others, such as wood, are poor conductors. Convection transmits heat by transporting groups of molecules from place to place within a substance. Convection occurs in fluids such as water and air, which move freely.
Radiation is the transfer of heat energy without the involvement of a physical substance in the transmission. Radiation can transmit heat through a vacuum.
Controlling Heat Transfer – The Key To Cold Chain Maintenance
3 types of heat transfer:

28
Basic Heat Flow – Convection is Most Critical to Temperature Control in Packaging
Convection: since convection goes on when air
is free to move, the benefit in container design is to allow heat to move to cold (e.g. heat from environment, passing through wall absorbed by frozen gels), thus providing a way to maintain the payload within the required temperature range.
© 2008 Tegrant Corporation, ThermoSafe Brands29
29
Most Critical Design Criteria for Cold Chain:
» 1. have an adequate amount of temperature stabilizers (e.g. frozen, refrigerated, room temp gels, dry ice, etc.);
» 2. Sufficient insulation in the container to limit the heat flow from the outside environment to the inside of the container for the duration of the transit period.
» 3. Adequate airflow within the container allowing convection to channel the heat away from the payload to the temperature stabilizers. Direct contact of the product and stabilizers will result in conduction and is not a desired design characteristic.

4. Understand the package handling environment
• Walk the “system” – learn times and temperatures• Storage/packing environment, pre-storage, packing and
post packing environments• Carrier options, differences in overnight vs. 2-3 day
express freight – segment analysis; best partners for freight forwarding
• Dynamic environment - truck, air options with shock, vibration & atmospheric pressure considerations
• Internal cGDP quality control points in place or needed?

Examples of Allowable Excursions for Distribution
• Example 1 (actual manufacturer’s information to wholesalers for distribution of their product):
– Storage: Refrigerated: 2-8°C– Distribution (shipping): 2-8°C, excursion to 25° no > 25°C
• Example 2 (actual information as above):
– Storage: Refrigerated: 2-8°C – Distribution (shipping): 2-15C, no excursions
© 2008 Tegrant Corporation, ThermoSafe Brands45

5. Know cold-chain suppliers capabilities
• Products available• Capabilities (engineering and testing?)• Locations, local and global supply considerations• Reputation• Quality Procedures, cGMP’s, ISO?• JIT local delivery & pre-frozen gels• Local packaging distributor partners?
© 2008 Tegrant Corporation, ThermoSafe Brands46
46
6. Understand requirements for package performance testing
• What are the shipping scenarios that need to be tested?• What is your level of risk to avoid over-engineering pkg. • Can you defend your test ambients? • Make sure the test lab’s quality system matches your
expectations (audit)• Determine requirements for trip monitoring –
considerations for using monitors in qualification tests• What level of documentation is needed? Will the lab’s test
report be adequate?

7. Perform design testing for a working system - DQ/ CQ
• Helps establish total packaging costs for each option = container, refrigerant, weight for transport costs
• Provides the foundation for a cost/benefit analysis to select the best package for qualification in a risk management scenario
• Leads to the detailed packing configurations to be qualified through the protocol development process for compliance

48
Thermal Testing Considerations
Tests are general simulations only – do not replace actual measurements in the distribution network (e.g. PQ);
Test conditions are under tight control vs real world; Primary issue is selection of defendable test profiles that
provide as much information as possible – e.g. summer and winter are typical, very few do a non-extreme normal profile too
Consider dynamic testing (e.g. atmospheric conditioning, shock and vibration) following thermal qualification,

8. Qualify the packaging system
• Collaborate with lab to write qualification protocol• Carefully consider the content (acceptance criteria, allowable
excursions)• Understand time and cost requirements for testing; min, max
loads, summer and winter testing, N=3, etc.• Consideration of running “normal” ambients in addition to
extreme summer and winter• Inclusion of dynamic testing (shock, vibration, pressure)• Incorporate in Validation Master Plan process

50
Cold-Chain Shipping Container Qualification
Manufacturer’s Consensus Practice:
» Qualify containers and configurations for each product or each family of product temperatures using a standardized thermal testing method
» Testing based on written protocols; testing done in triplicate (N=3) to assure reproducibility; min and max loads, summer and winter exposure profiles; plus normal profile for complete information;
© 2008 Tegrant Corporation, ThermoSafe Brands51
51
What Can Go Wrong – Things Not Discovered During Qualification:
Develop and qualify a package for a 2-8C product under an extreme summer temperature profile – in actual shipment the package never is exposed to those extremes
PRODUCT CAN FREEZE
© 2008 Tegrant Corporation, ThermoSafe Brands52
52
What Can Go Wrong – Things Not Discovered During Qualification:
Develop and qualify a package for a 2-8C product under extreme winter temperature profile, as above, in actual shipment, the temperatures are above normal
PRODUCT CAN GET TOO WARM
© 2008 Tegrant Corporation, ThermoSafe Brands53
53
9. Let suppliers know your expectations
• Will supplier sign a quality agreement?• Can they guarantee to supply what was tested?• Do they have traceability to their raw materials?• Are their manufacturing processes repeatable?• Are the quality control checks documented?• Will products be consistent from one lot/batch to the next?
Do they understand cGMP’s and change control?

54
Value and Sensitivity of Product/Product Packaging Dictate Level of Dynamic Testing
• Shock and vibration – ASTM 4169, ISTA 1A ruggedness/non simulation
• Conditioning, shock, vibration – ISTA 2A simulation performance
• Atmospheric conditioning and pressure becoming critical for syringes and pens – product displaced or damaged
© 2008 Tegrant Corporation, ThermoSafe Brands55
55
10. Implementation
Warehouse SOP’s should be developed based on test report/internal report
Warehouse staff should be trained and monitored regularly Companies should get feedback from customers who
receive packaging Companies should require notification if changes are made
in products supplied or carrier’s routes/methods Companies should monitor transit environment for changes,
document all deviations, failures of packages
