On July 1, the first domestic transparent oxide high-barrier film production line independently developed by ZGHT Aerospace Materials Technology Group passed the trial production verification, the core indicators of the product reached the international advanced level, and the production line was officially completed.
The 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 the 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 fully benchmarked with imported products from foreign countries, fully meeting customer needs, and will be launched soon. market.
Relying on the technology accumulation of the Key Laboratory of Vacuum Technology and Physics National Defense Technology for many years, ZGHT put forward the idea of transforming the "space station cable atomic oxygen protective coating aerospace technology achievements" into "the third generation of new barrier film products" A project team is formed on the achievement transformation platform to gather wisdom to tackle key problems.
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 with imported products from foreign countries to fully meet customer needs. Coming soon.
ZGHT has also started the first phase of high-barrier film capacity expansion in response to market demand and scale in different fields, and is expected to achieve an annual production capacity of 2,100 tons after completion.
The project team is working on the development of higher-index high-barrier film products in the high-end market of the industrial packaging field of quantum dot display, solar cells, etc. in accordance with the idea of “production generation, R&D generation”, and the institute will implement a full range of high-barrier film products by then It has become a leading enterprise in the field of new materials for high barrier films in China.
