TL;DR: In this article, a review highlights an ongoing shift of barrier coatings from traditional synthetic polymers to sustainable breakthrough materials for paper-based packaging and films, highlighting the implications of selecting different materials and processing options.
Abstract: Background The technology of food packaging is responding to significant market dynamics such as the rapid growth in e-commerce and preservation of fresh food, a sector that accounts for over 40% of plastic waste. Further, mandates for sustainability and recent changes in national governmental policies and regulations that include banning single-use plastic products as observed in sweeping reforms in Europe, Asia, and several US States are forcing industries and consumers to find alternative solutions. Scope and approach This review highlights an ongoing shift of barrier coatings from traditional synthetic polymers to sustainable breakthrough materials for paper-based packaging and films. Advantages, challenges and adapting feasibility of these materials are described, highlighting the implications of selecting different materials and processing options. A brief description on progress in methods of coating technologies is also included. Finally, the end fate of the barrier materials is classified depending on the packaging type, coating materials used and sorting facility availability. Key findings and conclusions Different types of coatings, such as water-based biopolymers, due to their greater environmental compatibility, are making inroads into more traditional petroleum-based wax and plastic laminate paperboard products for fresh food bakery, frozen food, and take-out containers applications. In addition, nano-biocomposites have been studied at an accelerating pace for developing active and smart packaging. Based on the momentum of recent developments, a strong pace of continuing developments in the field can be expected.

TL;DR: In this article, the state of the art of recent advancements on the modified, inspired, and architectured M41S- and SBA-n-based mesoporous arrays syntheses and its strategic use in the environmental approaches, mainly due to the great interest and need of the scientific community to obtain functionalized arrays with multiple features.
Abstract: The functionalized silica-based mesoporous molecular sieves are widely used successfully in various applications, mainly due to their interesting and unique textural and structural features, which allow their use in the most different scientific areas, such as catalysis, adsorption, separation of target molecules, drug delivery devices, chemosensors, biosensors, so on. In this review, we report the state of the art of recent advancements on the modified, inspired, and architectured M41S- and SBA-n-based mesoporous arrays syntheses and its strategic use in the environmental approaches, mainly due to the great interest and need of the scientific community to obtain functionalized arrays with multiple features. In view of the different approaches that have been extensively explored for the functionalization of nano-architectured arrays presented in the literature, it is possible to state that the strategies of modification of the M41S- and SBA-n-based mesoporous arrays can enhance the adsorptive, catalytic, and separation properties of the functionalized mesoporous architectures. Thus, evidencing that these multifunctional materials synergistically modified, with different pore geometries and architectures, can be widely used in the environmental remediation area, aiming to minimize environmental impacts, improve quality of life, and avoid the generation of waste, aiming at an increasingly green, clean, and sustainable footprint in the synthesis and application processes of these multifunctional materials.
