savEnrg™
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 suitable savEnrg™ 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.

savEnrg™ COOL Packs
  • 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.

savEnrg™ INCUBATION Packs
  • 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.

savEnrg™ COOL Packs
savEnrg™ INCUBATION Packs
  • 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.

Packing Refrigerated Specimens

savEnrg™ COOL Packs
  • Condition the savEnrg™ COOL Pack at +2°C until it is solidified. The phase change of the product is +5.5°C.
  • Place savEnrg™ COOL Pack at the bottom of the styrofoam box.
  • Place a thin layer of 3-4 paper towels (for insulation) over the savEnrg™ COOL Pack.
  • Put the refrigerated specimen bags into the shipper.
  • Place two paper towels over the refrigerated specimens, and place the savEnrg™ COOL Pack on top.
  • Immediately close the lid.
  • Quantity of savEnrg™ COOL 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.

Packing Ambient Specimens

savEnrg™ INCUBATION Packs
  • Condition the savEnrg™ INCUBATION Pack at +15°C until it is solidified. The phase change of the product is +22°C.
  • Place the savEnrg™INCUBATION Pack at the bottom of the shipper.
  • Place a thin layer of 3-4 paper towels for insulation over the savEnrg™INCUBATION Pack.
  • Put the specimen bags into the shipper.
  • Place two paper towels over the refrigerated specimens, and place the savEnrg™INCUBATION Pack on top.
  • Immediately close the lid.
  •  The quantity of savEnrg™ Warm 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.

Packing Frozen Specimens

savEnrg™ ICE Packs
  • 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.
