Legal documents such as ID cards, passports, and driver's licenses are the core carriers of personal identification, and their anti-counterfeiting properties are directly related to personal information security, social integrity systems, and national public security. Current traditional document anti-counterfeiting technologies (watermarks, fluorescent inks, magnetic stripes, etc.) are affected by the upgrade of counterfeiting technology, and have pain points such as easy copying, high identification thresholds, and easy failure after long-term use. Nanocellulose structural color materials have become a new core technology in the field of document anti-counterfeiting by virtue of their core advantages of being natural and environmentally friendly, difficult to copy, and easy to identify, effectively improving the level of document anti-counterfeiting and building a solid line of defense for information security. 1. Nanocellulose: a new green core material for document anti-counterfeiting. Nanocellulose is a green nanomaterial extracted from natural plants. Its core competitiveness in the field of document anti-counterfeiting stems from its unique structural color properties - different from the color development of traditional chemical pigments, the color of nanocellulose comes from the physical control of light by the microscopic orderly structure. This 'structure determines color'

At a time when global consumption is upgrading and the concept of 'green sustainability' is deeply penetrated, the daily chemical industry is accelerating to get rid of the limitations of traditional synthetic raw materials and iterate in the direction of natural safety, advanced efficacy, low carbon and environmental protection. As a new functional material derived from natural biomass, nanocellulose has quietly become the core force driving the innovation of daily chemical products with its unique nanoscale structure, excellent biocompatibility and designable interface properties, bringing gentle and efficient experience upgrades to skin care products, toiletries, makeup and other categories, and is more in line with the current consumers' core demands for 'clean, safe and sustainable'. Among them, Nanjing Tianlu Nano Technology Co., Ltd. is deeply involved in the field of nanocellulose, relying on mature preparation technology and precise scene adaptation capabilities to promote the large-scale application of this green material in the field of daily chemicals, allowing natural technology to truly empower product upgrades. 1. Nanocellulose: Nanocellulose, a high-performance bio-based material derived from nature and hidden in details

From nano-bio intelligent manufacturing to full life cycle closed loop, the competition in green packaging has entered a new stage of 'hard-core technology competition' - as the global plastic ban continues to escalate and the demand for precision protection and intelligent response of packaging materials in the high-end field continues to iterate, the shortcomings of traditional degradable materials with 'weak performance and single function' have become increasingly prominent, and breakthroughs in microbial synthesis technology have made bacterial cellulose (BC) a 'game-breaker' in the field of high-end green packaging. This kind of nanoscale bio-based material synthesized by microorganisms does not need to rely on plant resources. With its naturally formed three-dimensional network nanostructure and precisely controllable mechanical properties, combined with the empowerment of cutting-edge technologies such as atomic layer deposition and gene editing, it not only achieves a two-way breakthrough of '100% degradability' and 'high-end performance', but also builds a full-chain green system of 'biosynthesis-functional modification-scenario application-component recycling' to
