CTL liner is made of high reflective aluminum material which reflect 95% of radiant heat. The special installation method also creates air gap in between the container walls and the CTL to prevent conductive heat transfer. A total seal environment created by CTL liner forms an envelop preventing movement of air and thus preventing convection heat transfer.
In summer, when ambient temperature is 36 degrees, container inner temperature will reach between 55 - 60 degrees, but liner bag temperature is just within 40-45 degree, which gives about 10-15 degrees temperature difference.
It will have a better insulation effect to use both CTL and pallet cover together.
A: data loggers recorded temperature during transport with a container
B: data logger between CTL and the container
C: data logger inner CTL
From above, we observe the highest temperature difference can reach 11 degree between inside and outside of CTL, and the temperature changes slowly, so the insulation effect is more obvious.
