“…PLA is characterized by moderate barrier properties. In fact, PLA has high OTR compared to ethylene-vinyl alcohol copolymer (EVOH) but it offers lower OTR values than highly oxygen permeable polymer such as LDPE [40][41][42]. As reported by Auras et al the OTR of oriented PLA is ten times lower than oriented poly(styrene) -PS but six times higher than poly(ethylene terephthalate) -PET, which is widely used due to its excellent barrier properties against oxygen [43].…”

This work assesses the potential of maleinized cottonseed oil-MCSO as plasticizer in poly(lactic acid)-PLA films with improved ductile behaviour. The effects of MCSO are compared with commercially available maleinized oil, i.e. maleinized linseed oil-MLO in terms of mechanical, thermal and barrier properties, as well as morphology changes. Plasticized PLA formulations were obtained with a maleinized oil content in the 0-10 wt% range. Addition of both maleinized vegetable oils leads to a slight decrease in the glass transition temperature (Tg) of neat PLA from 63 ºC to 60-61 ºC. Nevertheless, MCSO provides better overall properties. Addition of 7.5 wt% MCSO increases the elongation at break by 292%. Regarding the barrier properties, both maleinized vegetable oils increase the oxygen transmission rate-OTR. Nevertheless, this increase is less pronounced in the case of MCSO thus indicating its higher efficiency compared to MLO. On the other hand, addition of both maleinized vegetable oils do not compromise the overall disintegration of the obtained PLA formulations, thus positioning these additives as environmentally friendly solutions to increase ductile properties in PLA-based films.

“…Since cinnamaldehyde essential oil mainly function as a preservative to inhibit microorganisms through volatile format at a certain concentration (0.025‰‐0.5‰) . The interaction of essential oils and polymer materials are interesting . The applying to the low temperature, physical adsorption control of the fibrous films may have greater advantages.…”

Electrospun ultra-fine poly(vinyl alcohol)/permutite fibrous film loaded with cinnamaldehyde essential oil was successfully fabricated.The morphology of fibrous filmswas characterized by scanning electron microscopy (SEM) and atomic force microscope (AFM). The fibrous film exhibited microstructure features with high porosity with the pore size distributed ranging from 1.7 nm to 56.7 nm. And the root-mean-squared roughness of fibers lifted to 546.5 nm when the addition of cinnamaldehyde essential oil (CEO) reached 0.25 mL. Attenuated total reflectance-fourier transform infrared (ATR-FTIR) spectroscopyconfirmed the existence of CEO in fibrous films and revealed physical interaction rather than chemical interactions existing between the film matrix and CEO. Endothermic peaks presented in differential scanning calorimetry (DSC) profile were probably rooted from existed mesoporous adsorption between the highly porous film matrix and CEO. Furthermore, the PVA/permutite/CEO fibrous film prolonged the shelf life of strawberries, confirming that the PVA/permutite/CEO fibrous film may be of interest for the development of active food packaging.

“…Polypropylene (PP) polymer belongs to polyolefins group ((C 3 H 6 ) n ) and mostly used for food packaging application due to its lowest manufacturing cost available in the market till now [6]. Other most common used polymers for packaging application are polyethylene terephthalate, polystyrene, polyvinyl chloride and polyvinylidene [7]. PP is a thermoplastic polymer with low density (0.9 g/cm 3 ), semi-crystalline, strong and light in weight [8].…”

Aim:The current study focuses on development of high oxygen barrier multi-layered packaging film for shelf life extension of Ready-to-Cook (RTC) idli batter. Place and Duration of Study: Department of Food Packaging and System Development at IndianInstitute of Food Processing Technology, Thanjavur, Tamil Nadu, India, between Aug 2018 and Dec 2019. Methodology: The developed multi-layered film composed with polypropylene (PP) nanocomposite by depositing silicon dioxide (SiO 2 ) on PP (0.010 mm) film and attached with different thickness of barrier layers were PP (0.010-0.053 mm) and ethylene-vinyl alcohol (EVOH 32%) film (0.066 mm) using layer-by-layer (LbL) process. The physical and chemical characteristics of commercial (A) and all developed multi-layered (B, C, D, E and F) films were tested for barrier and mechanical properties. Gaikwad et al.; IRJPAC, 21(1): 13-27, 2020; Article no.IRJPAC.54882 14 Results and Discussion: The SEM analysis confirmed that the developed PP nanocomposite multi-layered films have a presence of SiO 2 with quasi-spherical structure with diameter ranging from 200 to 500 nm. FTIR analysis also identified the presence of Si-O-Si group on all the developed PP nanocomposite films at wavenumber ranges from 1100-900 cm -1 and 467 cm -1 . The film composed with PP++SiO 2 +EVOH (sample F) showed lower in oxygen transmission rate (OTR) of 452.46±33.94 cc/m 2 /24h and water vapour transmission rate (WVTR) of 1.07±0.16 g/m 2 day. The batter stored in sample F film help to extend the shelf life upto 33 h at ambient temperature and commercially stored batter spoiled quickly (24 h) at ambient temperature.
