With the rapid development of precision medicine and regenerative medicine and the increasing consumer demand for safe medical aesthetics and green medical materials, pain points such as biological rejection and residual toxicity of traditional medical materials have become prominent. Nanocellulose (Nanocellulose), which is biocompatible, degradable and high-performance, has become the core choice for the upgrading of biomedicine and medical aesthetics industries. It is used in fields such as wound repair and drug delivery. As a high-tech enterprise deeply involved in the research, development, production and application of nanocellulose, Nanjing Tianlu Nano Technology Co., Ltd. (hereinafter referred to as 'Nanjing Tianlu Nano'), relying on mature technology and large-scale production capacity, is promoting the industrialization of this green nanomaterial in the fields of biomedicine and medical aesthetics, assisting the high-quality upgrade of the industry, and practicing the development concept of 'green empowerment, technology-driven'. Nanocellulose is mainly divided into CNF cellulose nanofibrils, CNC cellulose nanocrystals, and BNC bacterial nanocellulose. The raw materials come from

Under the dual-carbon strategy, green renewable materials have become the core direction of industrial upgrading. Nanocellulose, as a new nanomaterial extracted from natural biomass, has become the key to solving pain points and upgrading the paper industry with its advantages such as environmental protection, high strength, and degradability. Nanjing Tianlu Nanotechnology focuses on the research and development and production of nanocellulose, empowering the high-quality development of the paper industry. Nanocellulose: Definition, Classification and Core Advantages Nanocellulose is a fibrous material that deconstructs natural cellulose to the nanometer scale (1-100 nanometers in diameter) through mechanical, chemical and other processes. The raw material is derived from natural biomass such as wood and straw. It is rich in reserves, green and degradable. It is mainly divided into three categories and is suitable for different application scenarios: • Cellulose Nanocrystal (CNC): High crystallinity, strong rigidity, suitable for high-strength coatings and precision composite materials; • Cellulose nanofiber (CNF): has excellent flexibility and good film-forming properties, and is the most widely used type in papermaking; •

Global plastic packaging pollution is becoming increasingly serious, and disposable refractory products cause a large amount of white pollution, which goes against the 'double carbon' strategy and the concept of sustainable development. Nanocellulose (Nanocellulose), as a new type of natural biomass nanomaterial, has become a core breakthrough in the field of degradable packaging due to its excellent barrier properties, film-forming properties and environmentally friendly properties. Nanjing Tianlu Nano Technology Co., Ltd. is deeply involved in the research and development, production and sales of nanocellulose, assisting the implementation of the degradable packaging industry and promoting the green upgrade of the industry. 1. Nanocellulose: the core preferred material of degradable packaging. The core requirement of degradable packaging is to balance environmental protection and practicality. Compared with traditional degradable materials such as starch-based and PLA, nanocellulose has significant advantages. Nanjing Tianlu relies on its characteristics to create customized products for multiple industries and realize material value conversion. 1. Extremely environmentally friendly, eliminating white pollution from the source. Nanocellulose is made from agricultural and forestry biomass such as wood, straw, and bamboo.
