As a photovoltaic packaging film, the market demand for EVA film is growing day by day.

​​​​Polyethylene-polyvinyl acetate copolymer film, referred to as EVA film, refers to a thermosetting film made from EVA resin as raw material through modification, melt processing, molding and other processes. EVA film has the characteristics of good durability, high transparency, good sound insulation effect, and good adhesion. It is widely used in wire and cable, agricultural mulch film, photovoltaic modules, foam shoe materials and other fields.

​ ​ ​ EVA film can usually be divided into two categories: white EVA film and transparent EVA film. White EVA film refers to a film made by mixing white fillers such as titanium dioxide and EVA resin. It has the advantages of anti-ultraviolet, high reflectivity, anti-aging, and can change the light reflection path. It is widely used in photovoltaic modules; it is transparent EVA film has the advantages of good processing performance, low production cost, and high transparency. It is the mainstream product in the EVA film market, accounting for 55% of the market. Transparent EVA adhesive film has problems such as high water permeability and poor reflectivity, which can easily affect the power generation performance of photovoltaic cells. In the future, white EVA adhesive is expected to replace transparent EVA adhesive film and become the mainstream in the market.

EVA film can be used as photovoltaic packaging film and is widely used in photovoltaic modules. Benefiting from national policy support and strong market demand, the prosperity of my country’s photovoltaic power generation industry continues to improve. According to statistics from the National Energy Administration, my country’s installed photovoltaic power generation capacity will reach 390 million kilowatts in 2022, a year-on-year increase of 28.1%. As the development of downstream industries accelerates, my country’s EVA film market demand is strong. According to the “2023-2028 China polyethylene-polyvinyl acetate copolymer film (EVA film) industry market in-depth research and development prospects released by the Industrial Research Center The Forecast Report shows that my country’s demand for EVA film will reach 310 million square meters in 2022.

In recent years, the country has attached great importance to the development of the photovoltaic packaging film industry and introduced many policies to support it. In January 2023, six departments including the Ministry of Industry and Information Technology and the Ministry of Education jointly issued the “Guiding Opinions on Promoting the Development of the Energy Electronics Industry”. The document clearly proposed that we should vigorously develop and apply photovoltaic products and technologies, and improve the quality of key photovoltaic materials such as high-end packaging films. production capacity. Driven by national policies, my country’s EVA film industry will develop in a high-quality direction.

There are many EVA film manufacturers in my country, and the market competition is fierce. Foster, Haiyou New Materials, Saiwu Technology, Lushan New Materials, Wanhua Chemical, Mingguan New Materials, Dongfang Risheng, Jolywood, etc. are the main players in my country’s EVA film market. The EVA film used for encapsulating photovoltaic modules produced by Foster has been selected into the third batch of national manufacturing industry single champion products.

Industry analysts said that as a thermosetting adhesive film, EVA adhesive film has broad application prospects in the field of photovoltaic modules and is in demand in downstream Driven by this, its market space will continue to expand. Attracted by market prospects, the number of EVA film manufacturers in my country continues to grow, and market competition is becoming increasingly fierce. It is expected that companies with high-end EVA film production capabilities will occupy a larger market space in the future.
