TABLE 4.
Water vapor transmission (WVT), permeance, and water vapor permeability (WVP) of Eremurus spectabilis root fructans (ESRF) film and ESRF/Rhus coriaria L. extract (RCLE) composite films.
| Film sample | ESRF | ESRF/RCLE1 | ESRF/RCLE2 | ESRF/RCLE3 | ESRF/RCLE4 |
|---|---|---|---|---|---|
| WVT (×10−11 g/s.m2) | 1.495 ± 0.168a | 1.440 ± 0.100a | 1.185 ± 0.0341b | 1.083 ± 0.112b | 1.135 ± 0.085b |
| Permeance (×10−15 g/Pa.s.m2) | 4.987 ± 0.554a | 4.790 ± 0.329a | 3.945 ± 0.110b | 3.612 ± 0.371b | 3.785 ± 0.289b |
| WVP (×10−10 g/Pa.s.m) | 2.492 ± 0.277a | 1.542 ± 0.105b | 1.097 ± 0.030c | 0.859 ± 0.089d | 0.922 ± 0.070cd |
Note: Different lowercase letters in the same row indicate significant differences (p ˂ .05). The right numbers show the RCLE concentration.
