Abstract
Thermal insulation performance of new insulation packaging made of recycled PET nonwoven (thickness : 10 mm) was verified by conducting comparative experiment with an EPS box (thickness : 25 mm) and a double wall corrugated box (thickness : 7 mm). Three ice packs (300 g) were positioned 200 mm above the bottom inside each box, all of which are placed side by side and temperature change of 2 points (5mm under middle icepack and 130 mm under middle icepack) was recorded by data logger (GL-840, Graphtec) for 16 hours under the environment of 29℃. The new packaging box showed 75% higher insulation performance than the EPS box and 180% higher than the corrugated box. In order to figure out the reason for insulation performance difference among boxes, thermal conductivities of each box material were measured using heat flow meter (HFM436 lamda, Netzsch). U-value (thermal conductivity divided by thickness) of EPS was lower than recycled pet nonwoven by 57%, which seemed to be opposite to the result of insulation test of boxes. This was explained by high water vapor transmission rate of EPS (6 times higher than PET insulation) and air pocket effect of PET insulation.
