The project aims to develop the knowledge to manufacture ultra-light, mechanically very resistant and impervious packaging. The target market is the aerial delivery of consumer goods by drones. The current standard packaging, because of their weight, their lack of rigidity and water resistance, are not adapted to this growing market. The latest advances in nanocellulose research and/or cellulose filaments have demonstrated that it is possible to create foams based on these new fibers. Because of the aerated structure of these foams, the structure obtained when dried is light and rigid. The originality of the project is to create a packaging structure from these foams; which does not exist now. These are very innovative products with several challenges. The project has three technical and scientific challenges, the solution of which is the main objective of the proposed work.In a first step, we aim to preserve the maximum properties of wet foams in the dry state. We propose two approaches, one purely mechanical during the formation of the foam and its drying on paper machine and the other by chemical modification of the structural elements of the foam (cellulose filaments).In a second step, we aim to make the surface hydrophobic. We propose to use surface fatty acid grafting by means of a mild modification of an existing technology (Chromatogeny). This modification is made possible by the fact that the cellulose filaments have more active sites (OH) than a normal fiber of pulp.In a third step, we will create multilayer structures consisting of a cellulose filament foam core and a surface layer treated by chromatography. The project involves the training of 3 doctoral students, 2 master's students and two post-doctoral students. The knowledge developed during the project will allow the development of a new range of packaging products adapted to the new drone delivery market conditions.

该项目旨在发展知识，以制造超光线，机械耐药性和不透水的包装。目标市场是无人机消费品的空中交付。目前的标准包装由于其重量，缺乏刚性和防水性，并未适应这个不断增长的市场。纳米纤维素研究和/或纤维素丝的最新进展表明，可以根据这些新纤维创建泡沫。由于这些泡沫的充气结构，干燥时获得的结构是轻巧的。该项目的独创性是从这些泡沫中创建包装结构。现在不存在。这些是非常创新的产品，面临一些挑战。该项目有三个技术和科学挑战，其解决方案是拟议工作的主要目标。在第一步中，我们旨在保留在干燥状态下湿泡沫的最大特性。我们提出了两种方法，一种方法，一种在泡沫形成期间纯机械性及其在纸机上干燥，另一种是通过化学修饰泡沫的结构元素（纤维素丝）。 。我们建议通过对现有技术的轻度修饰（色谱）使用表面脂肪酸移植。纤维素丝比正常的浆纤维具有更多的活性位点（OH），从而实现了这种修饰。在第三步中，我们将创建由纤维素丝泡沫核心组成的多层结构和由色谱处理的表面层。该项目涉及对3名博士生，2名硕士学生和两名博士后学生的培训。项目期间开发的知识将允许开发适合新无人机交付市场条件的新的包装产品。
