Temperature Controlled Packaging
Pharmaceuticals, proteins, biological samples and other temperature sensitive products, including food items, are regularly shipped in containers year round and are subjected to a wide range of temperatures. Though they are shipped in insulated containers and/or climate controlled environments, the temperature stability of the shipping containers can be significantly improved by applying suitablesavEnrg™ Phase Change Material Products.
Advantages of Using Phase Change Materials (PCM) for Temperature Controlled Packaging:
can easily replace dry ice or gel packs
reduce the size of shipping containers
increase the temperature control duration during shipping
reduce transportation cost
are reusable
assure predictable and stable temperature control
are available in a wide range of temperatures
PCM-based Solutions for International Packaging and Shipping of Vaccines
As part of the WHO pre-qualification scheme, vaccine manufacturers are expected to ensure their packaging complies with the criteria specified below:
Class A packaging
The vaccine must be packed to ensure that the warmest temperature inside the insulated package does not rise above +8°C in continuous outside ambient temperatures of +43°C for a period of at least 48 hours.
Condition the savEnrg™ COOL Pack at +2°C until it is solidified.
The phase change of the product is +5.5°C.
The quantity required will vary based on size and insulation of the shipping container.
The product is non-toxic and can be used 1000’s of times.
Class B packaging
The vaccines must be packed to ensure that the warmest temperature inside the insulated package does not rise above +30°C in continuous outside ambient temperatures of +43°C for a period of at least 48 hours.
Condition the savEnrg™ INCUBATION Pack at +15°C until it is solidified.
The phase change of the product is +22°C.
The quantity required will vary based on size and insulation of the shipping container.
The product is non-toxic, non-flammable and can be used 1000’s of times.
Class C packaging
The vaccines must be packed to ensure that the warmest temperature inside the insulated package does not rise above +30°C in continuous outside ambient temperatures of +43°C for a period of at least 48 hours; the coolest storage temperature of the vaccine does not fall below +2°C in continuous external temperatures of -5°C for a period of at least 48 hours.
Condition the INCUBATION pack at +15C and COOL pack at +1°C.
The packs must completely solidify.
The phase change of the INCUBATION Pack is at +22°C. It will control the higher temperature to stay in the range of +22°C to +27°C when the outside ambient is at +43°C.
The phase change of the COOL Pack is +5.5°C. It will control the lower temperature to stay in the range of +2°C to +8°C as the outside ambient is at -5°C.
The quantity required will vary based on size and insulation of the shipping container.
The product is non-toxic and can be used 1000’s of times.
PCM-based Solutions for Shipping of Medical Samples
Medical samples sent to testing labs must maintain an appropriate temperature: ambient, refrigerated, or frozen.
Condition savEnrg™ ICE Pack at -28°C until it is solidified. The phase change of the product is -23°C. savEnrg™ICE Packs are a safe alternative to dry ice in less stringent applications.
Place savEnrg™ ICE Pack at the bottom of a styrofoam box.
Place 3-4 paper towels (for insulation) over the savEnrg™ICE Pack.
Put the frozen specimens into the styrofoam box.
Place 2 paper towels over the frozen specimens, and place the savEnrg™ ICE Pack on top.
Immediately replace the lid.
The quantity of savEnrg™ ICE Packs required will vary based on size and insulation of the shipping container.
The product is non-toxic and can be used 1000’s of times.
