“…Clearly, a wide range of polymers impregnated with both chemicals and natural extracts using scCO2 have been reported in the literature [35][36][37][38][39]. Among the natural compounds, OLE has been used for food preservation due to its reported AO, antibacterial and antifungal properties [40][41][42][43][44].…”

Poly(ethylene terephthalate)/polypropylene (PET/PP) films containing olive leaf extract (OLE) were obtained by supercritical solvent impregnation (SSI) in batch (BM) and semi-continuous (SM) modes.The study focused on the impact of pressure, temperature, CO2 flow and OLE on the properties of the impregnated films. Thermal analysis of non-impregnated samples revealed a decrease in the crystallinity of PP layer treated at 35 ºC and an increase in the Tg of PET treated at 55 ºC due to CO2 sorption. In impregnated samples, high pressures caused a decrease in the crystallinity of PP layer, whereas PET layer remained unaffected. Higher pressures favour impregnation in BM, whereas different trends were found for SM impregnations. Although the film properties were not compromised after impregnation, the CO2 stream used in SM slightly weakened the impregnated films. Overall, conditions of 400 bar and 35ºC in BM were favorable for producing highly antioxidant films with minor structural modifications.

“…As a result, active biodegradable films were obtained to be used in a wide range of applications. As was observed for thymol, other volatile compounds have been added by using the supercritical CO 2 -assisted impregnation such as R(−)carvone to LDPE [ 109 ] and cinnamaldehyde to PLA [ 95 ], with impregnation yields of 4.38 and 13%, respectively.…”

In the last years, many of the research studies in the packaging industry have been focused on food active packaging in order to develop new materials capable of retaining the active agent in the polymeric matrix and controlling its release into food, which is not easy in many cases due to the high volatility of the chemical compounds, as well as their ease of diffusion within polymeric matrices. This review presents a complete revision of the studies that have been carried out on the incorporation of volatile compounds to food packaging applications. We provide an overview of the type of volatile compounds used in active food packaging and the most recent trends in the strategies used to incorporate them into different polymeric matrices. Moreover, a thorough discussion regarding the main factors affecting the retention capacity and controlled release of volatile compounds from active food packaging is presented.

“…Fleming et al [48] reported values for the diffusion coefficients of dyes in PET films under scCO2 atmosphere of 6.75 ± 1.01 × 10 −14 m 2 s -1 (at 20 MPa and 80°C) using Raman microscopy data, whereas Goñi et al [21], reported diffusion coefficients of carvone into scCO2-swollen LDPE in the range of 6.5 × 10 −11 to 3 × 10 −10 m 2 s -1 (at 7-9.7 MPa and 35-60°C). The observed variability let to conclude that diffusion coefficient values are highly dependent on the polymer nature and characteristics (percentage of crystallinity, glassy or rubbery state), as well as the CO2 sorption and swelling ability and the different specific interactions that can occur between functional groups of the polymer and diffusing molecules.…”
