The high-barrier film is a multilayer structure film made by extruding a material with strong gas barrier properties and polyolefin with strong heat-sealing and moisture barrier properties at the same time. The high-barrier film can block the penetration of oxygen and water vapor, avoid the reproduction of microorganisms in the content, prevent its oxidation and mildew, and improve storage performance. High-barrier films are mainly used in the fields of food and pharmaceutical packaging, and high-performance high-barrier films can also be used in electronic devices, photovoltaic cells, and OLED packaging.

The manufacturing process of the high-barrier film mainly includes multi-layer composite, surface coating, surface modification, biaxial stretching, etc. High-barrier film usually has excellent barrier properties, mechanical properties, transparency, and printing adaptability. With the continuous development of downstream industries, the demand for high-barrier films in the Chinese market continues to grow.

In the future Internet of Things era, sensors will be ubiquitous, and the water vapor barrier film will lead sensors to be flexible, lightweight, and wearable. Flexible sensing applications based on flexible printed electronics have broad prospects, including infrared sensing, robot transmission Sensors, smart wearable sensing, biomedical sensing, etc. Once printed electronics break out, the demand for water vapor barrier films is also huge.

From 2014 to 2019, the compound annual growth rate of my country’s high-barrier film market was 15.1%; in 2019, the market size of my country’s high-barrier film was 10.27 billion yuan, a year-on-year increase of 10.3%. The high-barrier film market is expected to exceed 15 billion by 2024.

In the total supply of the high-barrier film market in my country, the total domestic production accounts for about 55%, and the total import accounts for about 45%. The external dependence is large, and the domestic products are mainly concentrated in the middle and low-end fields. The imported products are mainly High-end products. The high-performance high-barrier film industry has high technical barriers to entry. In the global market, representative companies mainly include DuPont in the United States, Arkema in France, Electrochemical in Japan, and SKC in South Korea.
