PCM for Temperature Controlled
Packaging
The industry uses gel-packs, ice and dry-ice
Consumers are looking for better methods to:
•control temperature
•reduce shipping weight
•reduce packaging waste
•reduce carbon footprint
Some are using qualified containers which
use higher quality, insulating material and
PCM for effective temperature control

From Wikipedia
Phase Change Materials (PCM) oscillate between solid and liquid
phase within a certain temperature range (Mansfield). When the
environment’s temperature is higher than that of the PCM, heat
transfers from the surroundings to the material, which creates a
cooling effect and changes PCM’s state from solid to liquid. When
the environment’s temperature is lower than that of the PCM, heat
transfers from the PCM to the surroundings, generating a
warming effect and PCM changes back to its solid state
PCMs are classified as latent heat storage (LHS) units.
Phase change occurs at a relatively constant temperature.

•Consumption of PCM products on a large scale is expected to
reduce energy demand by up to 50% by 2050
•By incorporating PCM in different applications, companies can
earn 10-20 times more carbon credits compared to other green
materials
•Most of the available PCMs have a long operating life of
approximately 20 to 30 years and need very little maintenance
(will vary based on use)
•PCMs have 5 to 6 times more heat storage capacity compared
to other materials

At Phase Change Point energy
is absorbed with almost no

Technology enables high
thermal energy storage for
heating or cooling needs when
and where needed.
Temperature Control with PCM

10. 10
•The temperature can be
controlled within +/-3 degrees
depending upon the type of
insulation. PCM is not a
substitute to insulation. It adds
thermal mass for a suitable
temperature.
