A critical overview of current approaches to the development of starch-containing packaging, integrating the principles of green chemistry (GC), green technology (GT) and green nanotechnology (GN) with those of green packaging (GP) to produce materials important for both us and the planet is given. First, as a relationship between GP and GC, the benefits of natural bioactive compounds are analyzed and the state-of-the-art is updated in terms of the starch packaging incorporating green chemicals that normally help us to maintain health, are environmentally friendly and are obtained via GC. Newer approaches are identified, such as the incorporation of vitamins or minerals into films and coatings. Second, the relationship between GP and GT is assessed by analyzing the influence on starch films of green physical treatments such as UV, electron beam or gamma irradiation, and plasma; emerging research areas are proposed, such as the use of cold atmospheric plasma for the production of films. Thirdly, the approaches on how GN can be used successfully to improve the mechanical properties and bioactivity of packaging are summarized; current trends are identified, such as a green synthesis of bionanocomposites containing phytosynthesized metal nanoparticles. Last but not least, bioinspiration ideas for the design of the future green packaging containing starch are presented.
本文对当前含淀粉包装材料的开发方法进行了批判性综述，将绿色化学（GC）、绿色技术（GT）和绿色纳米技术（GN）的原理与绿色包装（GP）的原理相结合，以生产对人类和地球都至关重要的材料。首先，作为GP与GC的关系，分析了天然生物活性化合物的益处，并根据纳入绿色化学品的淀粉包装更新了最新技术，这些绿色化学品通常有助于我们保持健康、环境友好且通过GC获得。确定了新的方法，例如将维生素或矿物质掺入薄膜和涂层中。其次，通过分析紫外线、电子束或伽马射线以及等离子体等绿色物理处理对淀粉薄膜的影响来评估GP与GT的关系；提出了新兴的研究领域，例如使用冷大气等离子体生产薄膜。第三，总结了如何成功利用GN改善包装材料的机械性能和生物活性的方法；确定了当前的趋势，例如绿色合成含有植物合成金属纳米颗粒的生物纳米复合材料。最后但同样重要的是，提出了设计未来含淀粉绿色包装的生物启发理念。
