“…Before biopolymers become serious commercial contenders, scientists must understand their physicochemical, mechanical, thermal, and chemical properties. Physicochemical properties include a gas barrier and mechanical properties that cover tensile strength, elastic modulus, and maximum elongation [10]. Scientists also need to understand how biopolymers react with various food items.…”

“…Biodegradable and compostable plastics are problematic in recycling as they are treated as impurities in conventional plastic feedstock [9]. Scientists have examined various constituents of plastics and polymers, particularly biopolymers and advanced polymer composites have claimed significant attention in the past few years [10]. Biopolymers, bio-based degradable polymers, still require significant improvement before claiming considerable market share.…”

Nanoparticles of zinc oxide (ZnO), polyhedral oligomeric silsesquioxane (POSS), and their hybrids were added to polylactic acid (PLA) using solution casting process at different weight percentages of the nanoparticles (1, 3, and 5 wt%) to form developed nanocomposites for food packaging applications. According to FTIR and XRD studies, both nanoparticles displayed fair chemical interactions with the PLA matrix. Furthermore, morphological investigations (SEM‐EDS) revealed that POSS, ZnO, and their hybrids were uniformly dispersed into the matrix despite some microaggregations at 5 wt% of nanoparticles, especially for those containing POSS. Moreover, adding 1 wt% of POSS to PLA increased its tensile strength and modulus by 20% and 149%, respectively, while decreasing the elongation‐at‐break by 54%. In addition, the tensile strength, tensile modulus, and elongation‐at‐break of PLA all increased by 7.5%, 28.7%, and 162%, respectively, with the addition of 1 wt% ZnO. Contact angle and surface free energy experiments demonstrated that after incorporating ZnO and POSS into the PLA matrix, the hydrophobicity of the samples increased, and POSS nanoparticles could minimize bacterial adherence effectively. In addition to the antibacterial properties of ZnO and POSS nanoparticles, increasing the concentration of hybrid nanoparticles up to 5 wt% expanded the bacteria's inhibitory zone, particularly in the case of Gram‐positive bacteria (Staphylococcus aureus). Finally, the hybrid nanocomposites exhibited both balanced mechanical characteristics and promising antibacterial activity compared with those with ZnO and POSS alone.

Food packaging has currently become an essential element in the world to address the rising demand for high quality food and to overcome the key challenges of sustainable food management while minimizing food waste. Nanotechnology, an emerging and versatile field plays a main role in offering tremendous benefits for innovative food packaging with the aim of preserving food quality, prolonging shelf‐life and avoiding post‐harvest losses. Nanomaterials are incorporated into synthetic polymers or biopolymer matrices in order to escalate mechanical and barrier functionalities of polymer and are effectively utilized in food packaging. This article reviews the various types of nanomaterials used for food packaging and the specific properties provided by each, while briefly explaining the active and intelligent packaging. Finally, an outlook on the future perspectives, toxicity effects and the novelty of nanotechnology‐based food packaging is provided while addressing the major concerns in the field for safe‐guarding food production and loss prevention.This article is protected by copyright.
