Thickness and permeance values in terms of water vapor permeance (WVP) and _D-limonene permeance (LP) of the YPACK210 film and active multilayer films with and without cellulose nanocrystal (CNC) coatings.

Sample	Thickness (mm)	Permeance
		WVP × 1011 (kg·m−2·Pa−1·s−1)	LP × 1011 (kg·m−2·Pa−1·s−1)
YPACK210 film 1 layer	0.060	3.22 ± 0.12 a	3.78 ± 0.37 a
YPACK210 1 layer (modeled)	0.140	1.38 b	1.62 b
Active multilayer with CNC *	0.140	0.87 ± 0.92 c	1.36 ± 0.24 c
Active multilayer with CNC **	0.140	0.89 ± 0.50 c	1.39 ± 0.77 c
Active multilayer without CNC	0.131	1.32 ± 0.17 b	1.59 ± 0.38 b

* measured by active interlayer side. ** measured by CNC interlayer side. a–c: Different superscripts within the same column indicate significant differences among samples (p < 0.05).
