“…Edible coatings are made from eatable materials and are part of all fresh-cut fruit products (Abu-Shama et al, 2020;Al-Tayyar et al, 2020;Anjum et al, 2020;Suriati and Suardani, 2021;Zhang et al, 2021). They are biodegradable, formed to coat a food, or placed between components that serve as a barrier to chemical, physical, and biological changes (Nicolau-Lapeña et al, 2021) such as mass decay by moisture, oxygen, light, lipids, and solutes, additive carriers, water vapor as well as the exchange of O 2 and CO 2 gases (Yu et al, 2021). According to Parven et al (2020), La et al (2021), Yu et al (2021), the application of edible coating also serves to improve appearance in the form of bright and shiny colors, retaining moisture, prevent weight loss, as well as antimicrobials.…”

The edible coating is an environmentally friendly technology that is applied to fresh-cut fruit products. One of the natural ingredients that are potentially applicable is aloe-gel because it contains several functional components. The main advantage of aloe-coating is that additives can be incorporated into the polymer matrix to enhance its properties. Additives tend to improve the safety, nutritional, and sensory attributes of fresh fruits, but in some cases, aloe-coating does not work. Furthermore, particle size determines the effectiveness of the process on fresh-cut fruits. Aloe-gel nano-coating can be used to overcome the difficulty of adhesion on the surface of fresh-cut fruits. However, quality criteria for fresh cut fruit coated with aloe-gel nano-coating must be strictly defined. The fruit to be processed must be of minimal quality so that discoloration, loss of firmness, spoilage ratio, and fruit weight loss can be minimized. This study aims to discuss the use of nano-coating aloe-gel incorporated with additional ingredients to maintain the quality of fresh-cut fruits. It also examined the recent advances in preparation, extraction, stabilization, and application methods in fresh fruits.

“…As to the devices on packaging membrane, the preservative emitters, indicators, sensors, identification labels and even power sources can be constructed. [ 66 ] Both applied strategies are decided based on the performance of the 2D materials. Owing to the adjustability and versatile performance (Figure 1), MXenes present great potential applications ranging from energy storage and harvesting to catalysis, water purification and desalination, electromagnetic interference shielding, communication, optics, electronics, plasmonics, sensors, actuators, composites, and medicine, [ 67 ] as well as inks in printing and packaging areas in daily life.…”

MXenes have been employed as two-dimensional (2D) nanostructured fillers in polymers matrix to design composites, which have tailored multi-functional properties with great potential applications in catalysis, sensor, energy storage, membrane and biomedicine areas. Analogous to 2D materials such as graphene and hexagonal boron nitrides, MXenes serve as robust support to expand a significant pathway to prepare composites. This paper outlines an overview of the recent development of MXenes and MXenes-based composites decorated by functional properties that potentially hold a promise on the packaging applications. A particular emphasis is to illustrate the essential properties of MXenes/polymer membrane intended food packaging such as barrier and antibacterial properties, biocompatibility and thermal stability. Furthermore, the progress and emergent values are presented in the perspective of instrumentation packaging that broadens prospects for antistatic, electromagnetic shielding and invisibility purposes. As a whole, this review promotes an emerging field to formulate the good ingredient of food packaging and safety to produce green and versatile membranes with high barrier performance. Finally, challenges and insightful perspectives for the application of MXenes in the packaging area are elucidated.

“…Poly (vinyl Alcohol) (PVA) is a transparent hydrophilic polymer that has been generally utilized in industry for quite a while (19)(20)(21)(22) . PVA is known to have solid oxygen barrier properties because of the solid hydrogen bonding of the hydroxyl (OH) groups in PVA, just as better rigidity, elongation, and abrasion resistance than general engineered materials.PVA as of now utilized in different fields, for example, fibers, films, adhesives, surface treatment chemicals, and coating materials (23)(24)(25) . Because of the hydrophilicity of PVA, its mechanical properties and electrical properties change significantly relying upon the outer humidity and its solubility, thickness (26)(27)(28) .…”

“…Because of the hydrophilicity of PVA, its mechanical properties and electrical properties change significantly relying upon the outer humidity and its solubility, thickness (26)(27)(28) . PVA is a water-soluble polymer broadly explored as a host for various types of Nano fillers (20)(21)(22)(23)(24)(25)29) . These observations recommend that the presentation of Nanosized particles into PVA do modify its properties and works as excellent biopolymer.…”

Objective: To prepare Poly vinyl alcohol (PVA) nanocomposites with novel GO-ZnO hybrid Nano filler and test its efficacy and applications. Methods: GO-ZnO hybrid nanocomposite filler was synthesized by modified hummer's method. Polymer nanocomposite films were prepared by solution casting method. Synthesis of GO-ZnO hybrid procedure is explained in detail. ZnO with average size of 26.74 nm were equally anchored on the GO surface. The properties of the PVA film and the PVA/Graphene Oxide/Zinc oxide composite film were analyzed by electrical, thermo mechanical & spectroscopic analysis. Findings: The results showed that the incorporation of graphene oxide and zinc oxide into the PVA matrix resulted in enhanced mechanical properties and thermal stability of PVA composite films. The tensile strength increases from 3.84 MPa of neat PVA to 10.48 MPa of PVA-0.05% GO-ZnO and Young's modulus increases from 104.407 to 106.765 MPa. The elongation behavior of the Polymer is increased by the addition of Nano filler and it varies from 15.94 Mpa of pure PVA polymer film to 239.52 MPa of 1% loading -GO-ZnO hybrid filler. Such an enormous improvement in the mechanical properties at such low stacking of GO-ZnO can be credited to a property of GO-ZnO hybrid nano-filler. DC conductivity studies were also under taken on the samples and the conductivity was found to be 2.895×10-6 S•cm−1 for 5% loading of nano particle while pure PVA is observed as 9.952×10-8.
