Food safety concerns arising from undetected food spoilage pose a significant risk to consumer health and well-being. Concurrently, the extensive utilization of nonbiodegradable petroleum-based plastic packaging films contributes to environmental degradation. Therefore, it is important to develop biodegradable food packaging materials endowed with active and intelligent functionalities for mitigating food wastage and safeguarding food integrity. This study focused on the synthesis of anthocyanin-curcumin-tannic acid nanoparticles (ACT NPs) through metal ion coordination and multiple hydrogen bonds to enhance the stability of active substances. Additionally, oxidized bacterial cellulose (OBC) was employed to improve the mechanical properties and biocompatibility of KCOA film. Drawing inspiration from self-wrinkling biomaterials, a sustainable multifunctional wrinkle-structured food packaging film was fabricated using the solution casting method. The resulting KCOA film exhibited exceptional attributes, including mechanical strength, reduced gas permeability, water resistance, ultraviolet-blocking capability, degradability, antioxidative properties, antimicrobial activity, and pH responsiveness. In pork preservation trials, the film considerably prolonged the shelf life of products while enabling the real-time monitoring of spoilage. This study presents a novel methodology for producing sustainable multifunctional wrinkle-structured films and underscores their potential as versatile packaging materials for concurrent food preservation and freshness monitoring.

“…As shown in Figure S6, the mechanical properties of QSCC bioplastics change significantly with the increase of CC content, and when the CC content is 20%, compared with other samples, QSCC has the best comprehensive mechanical properties, with a tensile strength of 11.3 MPa, Young’s modulus of 6.2 MPa, elongation of 182%, and toughness of 8.04 MJ·m –3 . It has a significant advantage over the newly published related work and has the potential to be applied in food packaging. , The tensile strength, Young’s modulus, elongation, and toughness of QSCC 1/7(20) bioplastic were 5.4, 1.2, 5.1, and 13.4 times higher than QS and 2.5, 1.5, 1.7, and 3.5 times higher than CC, respectively (Figures E and S7). Figure F exhibits the flexibility of QSCC 1/7(20) bioplastic, which can be processed into elaborate shapes through a straightforward folding process, which is beneficial for creating a suitable preservation environment for food.…”

Natural polysaccharide bioplastics are a promising alternative for nondegradable food packaging; however, some properties cannot be fully matched by petrochemical plastics. Herein, a biodegradable, eco-friendly bioplastic is constructed through dynamic electrostatic induct intermolecular cross-linking. By entropy initiation and electrostatic self-assembly, the protonated chitosan (CC) can be tightly bound to the polyelectrolyte complex (QS) composed of the quaternary ammonium chitosan and sodium alginate, further inducing crystallization through hydrogen bonds, resulting in the tensile strength and toughness of natural polysaccharide bioplastic (QSCC 1/7(20) ) being 5.4 and 13.4 times that of QS, respectively. Concurrently, the water resistance and gas barrier properties are also remarkably elevated. Due to the synergistic antibacterial activity of −NH 3 + and −N + (CH 3 ) 3 groups, the QSCC 1/7(20) achieves 3 h rapid sterilization (≥95%) and at least 5 day long-term bacteriostasis (≥99%), leading to foldable QSCC 1/7(20) that can effectively keep perishable fruit fresh for 8 and 7 days in static and dynamic situations, respectively. Furthermore, QSCC 1/7(20) can be recycled by low-carbon and waterassistance sustainable processes. Therefore, this work offers a prospective way to substitute petrochemical plastic packaging.
