Heat retention capacity and thermal effusivity of PP films with additives. Change of temperature difference from the initial temperature of films with 2% additives (a) and 4% additives (b) was observed under infrared light for 1 min (0–60 s) and 1 min after infrared light off (60–120 s). (c) Thermal effusivity of PP films with 2% additives at 2 s and 10 s touching time. (d) Films with additives showing increased thermal effusivity with the increase of concentration from 2 to 4%. (e) Films with additives showing decreased thermal effusivity with the increase of concentration from 2 to 4%.
