In this work, firstly, the optimal performance ratio of potato starch and polyvinyl alcohol (PVA) was selected, and then the sustainable high-grade food packaging film was developed by adding different amounts (0, 5, 10, 15, 20, and 25 wt% based on the starch mass) of functional additive lignin into the starch - PVA film matrix. Starch - PVA based films with different amounts of lignin were studied from the aspects of morphology, physical and chemical properties, barrier properties, mechanical properties and antioxidant properties. Mechanical tests showed that lignin significantly improved the tensile strength (TS) of the film and effectively blocked the passage of water vapor. Lignin, starch and PVA were linked by hydrogen bond to form polymer network structure, which improved the interfacial compatibility between polymers. The interaction between polymer molecules and the distribution of lignin particles were confirmed by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The high content of phenolic hydroxyl in lignin undergoes proton coupled electron transfer mechanism, which endows the composite film with high antioxidant activity, which is proved by DPPH radical scavenging activity experiment. At the same time, it also gives the film excellent UV barrier and antibacterial properties. The introduction of lignin in this study provides a valuable way for the preparation of multifunctional composite films using biomass as raw materials, and has a potential application prospect in food packaging.

An alternative transesterification with vinyl laurate (VL) was applied for chemical modification of hemicelluloses (HC) to prepare functional packaging films. Successful transesterification was confirmed by FT-IR and NMR. Semitransparent laurated HC (LHs) films were prepared by solvent casting method. SEM indicated the ordered honeycomb-patterned surface and the dense cross section of LHs films. The LHs films exhibited excellent hydrophobicity with water contact angle about 120° and the enhanced mechanical properties with tensile strength and elongation at break as 33.94 ± 3.09 MPa and 22.41 ± 2.87%, respectively. The water vapor permeability (WVP) and oxygen permeability (OP) values of LHs films ranged from 1.59 ± 0.07 to 2.23 ± 0.11 (10 −10 ·g/m·s·Pa) and 1.21 ± 0.04 to 4.24 ± 0.30 (cm 3 · μ m/m 2 ·d·kPa), respectively. Moreover, the films had acceptable antioxidant activity. In terms of these properties, the shelf life of green chilies could be largely extended to 15 days after packing with LHs films.

Multifunctional packaging materials made from biomass resources are key to achieving packaging storage and environmental friendliness. The aim of this study is to prepare high-performance cellulose-based packaging films to improve the high-value utilization of cellulose resources. In this paper, the blended films of sodium carboxymethyl cellulose (CMC) and poly(vinyl alcohol) (PVA) were used as the substrate and doped with tannic acid (TA)-coated cellulose nanocrystals (CNC@TA). Then, zinc ions (Zn 2+ ) were decorated on the film surface by adsorption self-assembly. The modified films ( Z -CPC@T 5 films) were prepared with excellent mechanical properties (tensile strength and elongation at break of 73.85 MPa and 19.68 %, respectively). Meanwhile, the presence of CNC@TA provided the films with UV and oxidation resistance. In addition, the zinc coating formed on the film surface conferred water resistance, hydrophobicity, and structural stability (water contact angle up to 97.09°). The modified films also showed excellent antimicrobial and water-vapor barrier properties. The modified films preserved cherries for at least 16 days with a quality retention of 87.20 %. In addition, cytotoxicity tests confirmed the non-toxic properties of the modified films. Overall, this strategic fusion of internal and external dual crosslinking expanded the application potential of active packaging materials.

Passion fruit peel is a food by-product containing a large amount of cellulose. This study investigated the effect of extracted cellulose nanocrystals (CNC) from passion fruit peel on the properties of electrospun zein/poly (ethylene oxide) (OZP) nanofibrous films loaded with oregano essential oil (OEO). These nanofibrous films were active packaging for pork preservation, in which OEO was the antimicrobial substance, while zein and PEO were film matrix with electrospinnability and film-forming property. The newly sourced CNC had a rigid rod-like structure with a high aspect ratio (27.9), which indicated that CNC from passion fruit peel could reinforce the better properties of materials than the near-spherical CNC from other sources. CNC had the higher crystallinity (64.87 %) compared with that of passion fruit peel powder (PP, 27.31 %) and cellulose powder from peel (PPC, 48.83 %). After the addition of CNC to OZP films, the average diameter of the electrospun fibers increased, which also led to a decrease in porosity. Furthermore, CNC addition improved the embedding ratio of OEO and retarded its release from the electrospun nanofibrous films. In addition, OZP films incorporating CNC (C-OZP) exhibited a higher tensile strength and water vapor barrier because hydrogen bonding formed by CNC and films matrix provided nanofibrous films with a higher crystallinity. The 3 % C-OZP suppressed the increasing trend of TVB-N and TVC of chilled pork during storage and prolonged the shelf-life of pork from 5 to 7 d. In conclusion, this study demonstrated that CNC from passion fruit peel can enhance the properties of OZP electrospun nanofibrous films, which had the significant potential as an active food packaging material.

Active packaging provides a way to prevent the food putrefaction effectively . Various studies provide information on the actual preservation effect of active packaging or the migration of active agents from active films into various food stimulants separately. However, there is little related data available regarding the combined analysis of release and preservation effect. In this work, we examined the properties of active food packaging films successfully produced by extrusion of ethylene vinyl alcohol copolymer (EVOH) films with clove essential oil (C). The characterization of mechanical, thermal and barrier properties of the packaging polymers film showed that the addition of clove essential oil did not decrease their properties and C as plasticizer improved process fluidity of EVOH resin. The release of C from film to various food stimulants was measured by using HPLC, and Fickian diffusion models were used to fit the data with appropriate equation. The effects of E/C (ethylene vinyl alcohol copolymer/clove essential oil) films on quality assessment of Grass Carp slice based on sensory analysis and biochemical indices during refrigerated storage (4 ± 1°C) were examined over the period of 10 days. Total volatile basic nitrogen (TVB-N), total viable counts, pH, TBA, water holding capacity (WHC) and texture properties were evaluated. The results indicated that the active film containing 3% clove essential oil had different release parameters in four food stimulants and it could effectively maintain the fish freshness and extend the shelf life to 7–8 days during cold storage compared with control group, which was only 4 days.

The adherence of foodborne microorganisms threatens human health, necessitating the development of antibacterial food packaging films. In this study, the antibacterial agent carvacrol (CV), hindered by its high volatility and intense aromatic odor, was encapsulated within the photosensitive metal-organic frameworks (MOFs) material PCN-224 (loading rate 50%). Subsequently, the microfluidic-blow-spinning (MBS) technique was employed for the rapid fabrication of CV@PCN-224/polycaprolactone (PCL)/chitosan (CS) nanofiber films. The incorporation of CV@PCN-224 NPs enhances the nanofiber films' thermal stability and mechanical properties and improves the water vapor permeability while maintaining the sustained release of CV over an extended period and good biocompatibility. Due to the simultaneous loading of antibacterial agent (CV) and photosensitive agent (PCN-224), the CV@PCN-224/PCL/CS films exhibited good synergistic antibacterial functionality, as demonstrated by effective inhibition against both E. coli and S. aureus . All results show the vast potential of the prepared nanofiber films in antibacterial food packaging.

The existing films used for fruit preservation suffer from insufficient preservation abilities. This study introduces Cu-tannic acid (Cu-TA) nanoparticles, synthesized from tannic acid (TA) and Cu 2+ , to enhance food packaging properties. Integrated into a chitosan-gelatin (CG) matrix, the resultant Cu-TA nanocomposite films exhibit superior antibacterial efficacy and killing rates of Escherichia coli and Staphylococcus aureus more than 99 %, and double the shelf life of strawberries, underscoring the exceptional freshness preservation capabilities of film. Additionally, the tensile strength of the Cu-TA nanocomposite films increased by 1.75 times, the DPPH radical scavenging percentage increased from 29.4 % to 68.4 %, and the water vapor permeability (WVP) decreased by about 60 % compared to the pure CG films. Comprehensive cytotoxicity and migration assessments confirm the safety of film, paving the way for their application in food packaging. The excellent performance of the Cu-TA nanocomposite films positions them as a formidable solution for protecting perishable food items.

Recently, nanosized cellulose materials preparation has been extensively increased from the sources of sustainable materials and utilization in various functional applications as nanofillers. Cellulose nanofibrils (CNF) extraction through green bio-based materials featured as promising interest in the field of science. In this research, cellulose nanofibrils were extracted from a cellulose rich biomass Ficus natalensis barkcloth. Furthermore, extracted cellulose nanofibrils and Zinc oxide nanoparticles (ZnONPs) were mixed and casted to posterior analysis of formed sodium carboxymethyl cellulose (CMC) film at various concentrations of CNF (1 wt%, 5 wt%, 8 wt%, and 12 wt%) and fixed amount of ZnONPs (0.5wt%) based on CMC weight. Results revealed that CNF was smoothly distributed in the polymer matrix to form even and flexible films indicating the cellulose nanofibrils and zinc oxide are highly compatible with the CMC. Similarly, the water solubility percentage (WVP) of CMC film was low at lower content of CNF, and increased with the increase of CNF percentage. Addition of CNF and ZnONPs in nanocomposite films improved the thermal stability values and antibacterial activities of CMC films. Thus on the basis of various tremendous performance, this study showed that F.natalensis barkcloth could be considered as an alternative source of cellulose nanofibrils. Similarly, the prepared nanocomposite films can have potential application in packaging films for the extension of shelf life of fresh and minimally processed fruits and vegetables.

Natural and high-quality biomass-based coating films are considered promising packaging to consumers. However, the poor mechanical properties and weak antimicrobial activity of biomass materials have limited their practical application. A cleaner and low-cost strategy is used to prepare antimicrobial, self-recovery, and biocompatible coating films using tamarind kernel powder (TKP) and chitosan (CS). The TKP protein and chitosan chains were covalently cross-linked with tetrakis(hydroxymethyl)phosphonium chloride (THPC) to form a three-dimensional network based on THPC-amine dynamic bonds, and act as a sacrificial bond. Then, the hydrogen bond forms an interpenetrating network to build a strong multi-network film. Thus, the THPC multi-crosslinking TKP based films showed enhanced stretchable property (increased from 3.23 % to 77.54 %), and self-recovery after 30 min of recovery. Additionally, the film has been found to exhibit low water vapor permeability, low oxygen transmittance rate, and excellent antimicrobial efficiency (maximum inhibition zones: 24.39 mm). Moreover, the prepared films were demonstrated to be biocompatible and non-hemolytic based on cell viability and hemolytic activity assays. The method described herein could broaden the scope of biomass-based materials in the realm of antimicrobial coating films.

Starch (SR)/carboxymethyl cellulose (CMC) based antimicrobial films have been widely applied in packaging field. As a high-effect antimicrobial agent, the surface charge of imidazolium salt plays an important effect on antimicrobial performances of starch/carboxymethyl cellulose. Here in, the surface charge of dodecyl imidazolium bromide salt was regulated via thiol-ene reaction. Furthermore, antibacterial films were prepared by mixing imidazolium salts with SR/CMC via solution casting method. Under the optimized ratio of CMC to SR, the antibacterial activity for as-prepared ternary polymer blend films was enhanced with the increasing of surface charge of imidazolium salt. The sample of ADSC-01 film with highest surface charge showed best antibacterial properties for E. coli and S. aureus with the inhibition zone of 3.20 cm and 3.00 cm, respectively. In addition, hydrophobic property exhibited similar positive correlation with the surface charge. Therefore, this work provides a new route to regulate the antibacterial activity of bio-based ternary polymer blend films in the packaging.

The development of biodegradable packing materials is a global priority due to the huge volumes of plastic refuse entering landfills and the environment. In this study, a series of biodegradable nanocomposite films based on poly(butylene adipate-co-terephthalate) (PBAT) and reinforced with an organophilic layered double hydroxide (OLDH) were scale-up fabricated. The OLDH nanosheets with a basal spacing of 4.07 nm were presynthesized on a large-scale by solvent-free high-energy ball milling. All of the PBAT/OLDH nanocomposite films (0.5–4 wt % OLDH) showed a uniform dispersion of OLDH nanosheets in the PBAT matrix. A PBAT/OLDH film containing 1 wt % OLDH (denoted herein as OLDH-1) demonstrated outstanding thermal, optical, mechanical, and water vapor barrier properties compared with a pure PBAT film (OLDH-0), including a 37% reduction in haze and a 41.9% increase in nominal tensile strain at break dramatically. Furthermore, the food packaging measurement revealed that the OLDH-1 film showed a better packaging effect than the pure PBAT film and commercial polyethylene packing materials. The feasibility of scale-up manufacture and the excellent processability, manufacturing scalability, mechanical performance, optical transparency, water vapor barrier properties, and food packaging performance of the PBAT/OLDH nanocomposite films encourage their future application as biodegradable packaging films.

The resource utilization of waste bagasse (SB) is a green and effective solution to reduce environmental pollution . However, traditional methods for recycling of bagasse have the technical bottlenecks, including, secondary pollution, low efficiency, high cost and small production scale. Here, we develop a novel mechanical activation technology to convert SB in situ into zinc oxide-tannic acid-SB (ZnO-TA-SB) with antibacterial activity as multifunctional additives for packaging films. Unlike traditional methods that demand harsh reaction conditions, this novel strategy for the resource utilization of SB is convenient, green, efficient and large-scale. The results show that the bactericidal activities of ZnO-TA-SB against E. coli and S. aureus are >99 %, confirming the strong spectral antibacterial activity of ZnO-TA-SB. With the addition of ZnO-TA-SB to carboxymethyl cellulose (CMC) film, the tensile strength , elongation at break, O 2 barrier property of ZnO-TA-SB/CMC film are increased by 1.43, 2.49, 2.09 times compared with CMC film, respectively. Furthermore, ZnO-TA-SB/CMC film effectively keeps the appearance and freshness of strawberries for more than 18 days. Notably, ZnO-TA-SB/CMC film is easily degraded in soil and used as a nutrient for crop growth without secondly pollution. Therefore, this work develops a new strategy for the resource utilization of waste biomass, and obtains green, clean and high-value products from waste biomass.
