Development of active packaging film made from poly (lactic acid) incorporated essential oil

Active Chicken Meat Packaging Based on Polylactide Films and Bimetallic Ag–Cu Nanoparticles and Essential Oil

“…These changes in color values have been accredited to coloring ingredients of CEO ( a * = –0.18 and b * = 1.75). Similar effects on color due to the addition of essential oils into PLA have been reported by Qin, Li, Liu, Yuan, and Li ().…”

“…These changes in thermal properties of CEO loaded PLA films are attributed to the ease in PLA crystallization at lower temperatures (Martin & Averous, ). A similar behavior in thermal properties of biopolymer/EO composite films has been reported (Javidi et al., ; Qin et al., ). However, Yahyaoui, Gordobil, Díaz, Abderrabba, and Labidi () reported a small change in T c with an increase of crystallinity for PLA/EO films produced with myrtle, thyme oils, and rosemary.…”

Effect of multiscale structure on the gas barrier properties of poly(lactic acid)/Ag nanocomposite films

“…Water vapor permeability (WVP) of the PLA/nano‐Ag composite film was tested according to the American Society for Testing and Materials (ASTM) E 96‐95 standard method. It was determined using a water vapor transmission testing cup filled with the silica gel as it was described in a previous study . Three replications were made for each film, and the average value was taken for analysis.…”

“…In recent years, biodegradable polymers represent an alternative to replace petroleum‐based resins because of increasing environmental concerns, particularly in short‐term applications . Among the different biopolymers, poly(lactic acid) (PLA) is a popular choice for the preparation of biodegradable bioplastic as it has relatively good mechanical properties . PLA is a versatile material that can be obtained from renewable resources such as sugar beet, corn, and potato starch .…”

Sea Squirt Shell Protein and Polylactic Acid Laminated Films Containing Cinnamon Bark Essential Oil

“…TS generally decreases when essential oils are added to the biopolymer films, including PLA films (Ahmed, Mulla, & Arfat, ; Lee, Yang, Lee, & Song, ). According to the report of Qin, Li, Liu, and Yuan (), TS decreased from 45.8 to 16.8 MPa by the addition of essential oils to the PLA film. Yang and Song () reported that TS of PLA films decreased from 31.99 to 12.19 MPa and El decreased from 205.9% to 22.0%, as the addition of essential oils reduced molecular interactions, and the film matrix became heterogeneous through the crystallization of essential oil droplets.…”
