China News Network Lanzhou, July 1 (Reporter Ding Si) On the 1st, the 510 Institute of the Fifth Institute of China Aerospace Science and Technology Group Co., Ltd. (hereinafter referred to as the "Aerospace 510 Institute") announced that the first domestic article developed by the institute The transparent oxide high-barrier film production line has recently passed the trial production verification. The core indicators of the product have reached the international advanced level, and the production line has been officially completed.
Transparent oxide high-barrier film is the third generation of new-type barrier film products. It has all the advantages of excellent barrier performance, good film adhesion, resistance to cooking, low cost, no pollution, energy saving and environmental protection. It is the high end of current and subsequent key developments. Functional film materials are widely used in product packaging and packaging in many fields such as food and medicine. They have huge market capacity and very broad prospects.
The production line has successfully passed the trial production verification of continuous plating of 500,000 square meters. After multi-batch sampling testing, the core indicators of the high-barrier film products developed and produced by the research institute are completely benchmarked with imported products from foreign countries, which fully meet customer needs and will be launched soon. market.

According to the introduction of Aerospace 510, due to its technical difficulties, high development costs, and high monopoly of production equipment, only a few countries such as Japan and the United States can achieve small batch supply, and domestic stable supply capabilities are not yet available. It is still dominated by the second generation of aluminized film products. The new barrier film products and technologies have not yet achieved independent controllability, and there is an urgent need to overcome the problem of "neck pinching" in this field and achieve localized substitution.
Relying on the technology accumulation of the Key Laboratory of Vacuum Technology and Physics National Defense Technology over the years, the Aerospace 510 Institute has made full use of its "Yangtze River Delta Industrial R&D Base" location advantage, keenly grasping the market opportunities, and proposed the "space station cable atomic oxygen protective coating aerospace technology achievements "Transform and develop into "the third generation of new barrier film products" idea, and set up a project team on the research results conversion platform to gather wisdom to tackle the problem.
The project lasted 4 years and innovatively proposed a "one-time film formation" process plan, which has the characteristics and advantages of higher plating efficiency, lower production cost, and adjustable index flexibility. The project team has conquered and mastered core technologies such as precise control and adaptive adjustment of small tension, long-term winding coating protection, and stepped gas distribution. It has authorized more than 10 national invention patents and has completely independent intellectual property rights.
At present, the production line has successfully passed the trial production verification of continuous plating of 500,000 square meters. After multi-batch sampling testing, the core indicators of the high-barrier film products developed and produced by the research institute are fully benchmarked against foreign imported products, and fully meet customer needs. Coming soon.
In accordance with the market demand and scale of different fields, the 510 Institute of Aerospace has launched the first phase of high-barrier film capacity expansion work. It is expected to achieve an annual production capacity of 2,100 tons after completion, which will bring nearly 200 million yuan to the institute every year. Sales revenue. Subsequent, with the continuous improvement of production capacity, the scale of income will increase exponentially, and the real realization of industrialization will become an important support for the vacuum application product business segment of the institute.
The project team is working on the development of higher-index high-barrier film products in the high-end market of industrial packaging fields such as quantum dot display and solar cells according to the "production generation, R&D generation" thinking. It has become a leading enterprise in the field of new materials for high barrier films in China. (Finish)
