Antifungal effects of the carvacrol-containing films exhibited in the micro-atmosphere bioassays, i.e. without direct contact between the studied films and the microbial cultures using cherry tomatoes as the food model. (a) full inhibition of A. alternata development after incubation with a 9-layer (LDPE/[HNTs/carvacrol])/EVOH film; (b) A. alternata development after incubation with a 9-layer LDPE/EVOH film; (c) full inhibition of Rhizopus spp. development after incubation with a 9-layer (LDPE/[HNTs/carvacrol])/EVOH film; (d) Rhizopus spp. development after incubation with a 9-layer LDPE/EVOH film. The cherries were incubated with the films at 23 °C in the dark for 4 days. The results presented in (a,c) are characteristic for all carvacrol-containing films. The results presented in (b,d) are characteristic for all carvacrol-free films. All photographs were taken after the top and circumference films were removed.
