Cover Story: Novel packaging films that were prepared with or without the incorporation of a natural-halloysite (HNT)/carvacrol (CV)-extract nanohybrid with LDPE and coated externally, directly, or via corona treatment with carvacrol essential oil are studied in this report. According to the results from FTIR spectroscopy and a carvacrol release kinetic analysis, this technique led to a higher number of carvacrol molecules nanocoated on the surface of all the tested films. All the corona-treated films also exhibited higher total antioxidant activity and higher EC50 values. The most promising kind of active film, the carvacrol-coated and corona-treated LDPE film incorporated with 10 %wt. halloysite nanotubes that were also impregnated with carvacrol, exhibited over 40% higher water and oxygen barrier performance than that of the pure LDPE film.
