Analysis of the application fields and market development prospects of China’s silicon oxide-coated and alumina high-barrier membrane materials in 2023

High barrier film is a type of packaging material. It is mainly used for packaging food, medicine, cosmetics and environmentally sensitive items to ensure the quality and safety of products during storage, transportation and sales. With the rapid development of the packaging industry and the improvement of people’s living standards, high-barrier materials are also constantly upgraded, going from organic films to aluminum foil/aluminum coatings to oxide-plated high-barrier films. Among them, oxide-plated high-barrier films are in organic Silicon oxide and aluminum oxide are evaporated or chemical vapor deposited outside the film. The product has excellent performance, good barrier properties and little pollution.

Research on oxide-plated high-barrier films first began in the 1980s. Japan’s Mitsubishi Resin successively used PVA, PET, and PA as base materials to study the use of evaporated inorganic silicon oxide as a barrier layer. However, due to technical and cost reasons, it has not been established to a certain extent. Market size. At the beginning of the 21st century, the 100kw high-power electron gun developed in Germany was used to evaporate silicon oxide barrier layers, which promoted the development of oxide barrier films. Since then, the British company BOSTCH has introduced technology to directly prepare barrier layers by thermal evaporation of aluminum. Physically evaporated silicon oxide and aluminum oxide barrier films are mainly prepared by physical vapor deposition combined with plasma-assisted chemical vapor deposition. They have high production rates and are widely used.

Alumina-plated high-barrier film products have the characteristics of high transparency, high temperature resistance, microwave processing, direct printing, safety and environmental protection, and have fragrance retention. Silicon oxide-coated high-barrier film materials have excellent barrier properties, but their heat-sealing properties are reduced. They can be combined with other films with better heat-sealing properties during use.

The “2023-2028 China Silicon Oxide Plating and Alumina High Barrier Membrane Industry Market In-depth Research and Development Prospects Forecast Report compiled and released by the Industrial Research Center 》shows that currently, driven by the packaging demand for downstream food, pharmaceutical, and chemical products, packaging film materials continue to develop rapidly, and the demand for new film materials with high barrier properties is growing rapidly. Oxide-coated high-barrier films can also be used in electronic device packaging and flexible display production, and market demand is growing rapidly. Due to factors such as the technical difficulty of alumina-coated and silicon-oxide high-barrier film products, high production and R&D costs, and the monopoly of upstream production equipment, domestic production capacity is not high. In recent years, with the advancement of technology, domestic oxide high-barrier films have been plated. The transparent oxide high-barrier film production line independently developed by the 510th Institute of the Fifth Academy of China Aerospace Science and Technology Corporation has fully passed trial production verification and can achieve an annual output of 2100 upon completion. tons of production capacity; Yongju Technology’s transparent oxide high-barrier composite film will also be put into production in 2022, with an annual output of up to 230 million square meters. In 2022, Nantong Sisheng New Materials will also build new silicon oxide and alumina high barrier film projects.

It is expected that with the advancement of technology and the continued development of the downstream demand market, China’s market prospects for oxide-coated high-barrier film products will be better in the next few years, and the industry will have greater room for development.
