“…9−11 Plastic films with an oxygen transmission rate (OTR) of over 10,000 cm 3 /m 2 •d can induce a desirable modified atmosphere within fresh produce packaging throughout the storage period. 12 Environmental concerns regarding plastic food packaging waste have recently increased, with both packaging manufacturers and consumers becoming more conscious of the use of petroleum-based plastic films. 4,13,14 The development of biodegradable films made from natural resources offers a solution to the critical problem of plastic waste disposal, replacing fossil-oil-based packaging materials.…”

This study focused on improving the mechanical properties of the poly(butylene succinate) (PBS) film by incorporation of poly(butyrate adipate terephthalate) (PBAT). At 20 wt % PBAT, elongation in the transverse direction improved by 373% while maintaining high tensile strength (27 MPa) and Young's modulus (262 MPa). The PBS80/PBAT20 composite film exhibited optimized mechanical properties. The absorbance coefficient of microperforated film at 980/cm for the 80PBS/ 20PBAT mix, corresponding to the 10.2 μm CO 2 laser wavelength, was 65/cm, indicating high film capability to absorb energy from the CO 2 laser. The introduction of microholes enhanced the gas permeability of the PBS/PBAT film. As fluences increased from 187 to 370 J/cm 2 , there was a notable increase in microhole area in 80PBS/20PBAT film from 19,375 to 46,421 μm 2 . Concurrently, the gas transmission rate for a singular hole increased from 45 to 210 cm 3 /d for the oxygen transmission rate (OTR) and from 115 to 220 cm 3 /d for the CO 2 transmission rate (CO 2 TR). For mango packed in microperforated 80PBS/20PBAT films, the O 2 levels inside the package gradually dropped and remained at 14.2% in PBS80/PBAT20-MP1 (OTR ∼ 68,900 cm 3 /m 2 •d) and 16.7% in PBS80/PBAT20-MP2 (OTR ∼ 131,900 cm 3 /m 2 •d), while CO 2 content increased to 6% for PBS80/PBAT20-MP1 and 4% for PBS80/PBAT20-MP2 throughout 33 days. On day 2 of storage in the nonperforated package, O 2 content dropped to 2% while CO 2 content rose to 22%. Mango packed in the 80PBS/20PBAT film package exhibited an unsatisfactory freshness quality due to the detection of a fermentative odor on day 5 of the storage period. Total soluble solids, color, and weight loss of mango remained stable during storage in all microperforated films. Results demonstrated that the mango shelf life was significantly extended by 35 days using 80PBS/20PBAT-MP1. Laser perforation offered a practical method for improving gas transmission rates (OTR and CO 2 TR) of 80PBS/20PBAT film for mango packaging.

“…Thus, the shelf‐life extension for fresh‐cut durian can be achieved with an equilibrium modified atmosphere packaging (EMAP) in the cold storage. With balancing the respiration rate of the fresh produce and the gas permeability of the packaging, the steady‐state condition of O 2 and CO 2 gases can be maintained in the package . These phenomena result in a retardation of biological processes such as respiration, transpiration, and ripening that can retain the freshness quality of fresh fruits and vegetables …”

Development of multilayer films with improved aroma barrier properties for durian packaging application

et al. 2019

The symmetrical A/B/A structure of multilayer blown films was fabricated in this study. The immiscible low-density polyethylene/polylactic acid (LDPE/PLA) blend was set as a core (B) layer and LDPE was used as skin (A) layers. The compositions of PLA in the core layer were varied from 20 to 50 wt%. The thickness of each layer was 10 μm (total film thickness of~30 μm). In a blown film co-extrusion process, the morphology of the fiber/ribbon-like structures of LDPE/PLA blend was developed.Such structures had interesting effects on gas permeability and aroma barrier properties of the films. For instance, multilayer LDPE films containing 40 and 50 wt% PLA (P40 and P50) showed the reduction of oxygen permeability (PO 2 ) approximately 20% and 43%, respectively, compared with the neat LDPE film. A long tortuous path for gas and aroma transportation through film thickness was created from the developed ribbon-like structures of the PLA minor phase. For durian packaging application, fresh-cut durian of 300 g was packed in the developed multilayer films, LDPE, and HDPE (Control), stored at 4°C for 7 days. Results demonstrated that the steadystate condition of 10% to 13% O 2 and 8% to 10% CO 2 was achieved in all packages except in the HDPE. Moreover, the P40 and P50 films exhibited an outstanding aroma barrier property for three major durian volatiles: diethyl sulfide, ethyl propanoate, and 2-ethyl-1-hexanol. Overall results clearly indicated that the multilayer LDPE films containing PLA exhibited a significantly improved aroma barrier performance with optimum gas permeability desirable for modified atmosphere packaging to retain quality of fresh-cut durian throughout the storage period.

“…The most critical factor to obtain the desired MAP is the package specification, especially the ones related to barrier properties. If a package with very low oxygen transmission rate is used in MPP with high respiratory rate, it can result in a reduction of the internal level of O 2 , leading to anaerobic respiration, loss of quality, and increasing the risk of contamination by anaerobic pathogens (Chinsirikul et al, ).…”

This study aimed to evaluate the quality changes of the minimally processed escarole under passive modified atmosphere, packaged in different flexible plastic packages, which included polyvinyl chloride (PVC) stretch film, low‐density polyethylene (LDPE) bag, polypropylene (PP) bag, and bi‐oriented polypropylene (BOPP) bag, during storage for 20 days at 0°C and 90%–95% RH. The atmosphere of 16% O2and 3% CO2 formed in the PVC overwrap package provided the lowest browning index and the best conservation of ascorbic acid, chlorophyll, and carotenoids. During the experiment, no differences in phenolic compounds and polyphenol oxidase activity among the treatments were observed, while the activity of peroxidase showed peaks in different analysis days. Weight loss of all samples did not exceeded 1%. The minimally processed escarole showed sensitivity to high CO2 concentrations. Thus, a simple PVC stretch film provided the best visual and nutritional preservation of the minimally processed escarole. Practical applications Escarole is one of the most consumed leafy vegetable as a minimally processed product, however, there is no information about its quality changes associated with the package. This produce is widely commercialized in the same package of other leafy vegetables. This research has focused on application of passive modified atmosphere technology for quality preservation of escarole during storage, in order to indicate the most adequate package for its quality and nutritional conservation. The results implied that the quality of minimally processed escarole is better‐maintained using PVC stretch film, which is quite different from the usual plastic bags used for minimally processed leafy vegetables. This information is quite interesting at processer and market levels in order to standardize the packaging of this product and prolong its visual and nutritional quality.
