On January 16th, Anhui wanwei updated high-tech material industry co.,ltd. (hereinafter referred to as "Wanwei High tech") announced its investment in the construction of a 20000 ton/year biomass polyvinyl alcohol water-soluble film production line project. According to the announcement, Wanwei High tech plans to invest 112 million yuan to build a 20000 ton/year biomass polyvinyl alcohol water-soluble film production line project.

Polyvinyl alcohol (PVA) water-soluble film, abbreviated as PVA film, is a high-performance and biodegradable green packaging material. Its main component is PVA resin (about 75%), which can be widely used in food packaging, clothing and textile packaging, medical packaging, washing packaging, printing, etc.

Compared with other thin film products, PVA film is superior in glossiness and transparency. Compared with commonly used glass paper, PVC film, etc., its reflectivity is more than 20% higher, and its transmittance exceeds 50%. In terms of barrier properties, PVA film has strong permeability to water and ammonia, and its moisture permeability is similar to that of glass paper, which can ensure that no fog droplets are generated when packaging hot and wet items; At the same time, it has superior barrier properties for oxygen, nitrogen, hydrogen, helium, argon, and carbon dioxide. Under dry conditions, its oxygen permeability coefficient is the lowest among various resin films. Under atmospheric pressure, its barrier rate for oxygen is about 1000 times that of commonly used polyethylene films and 300 times that of polypropylene films, making PVA films have excellent fragrance retention and anti sublimation performance of packaging materials. Using PVA film packaging not only maintains the fragrance of the packaging material well, but also prevents the packaging material from being affected by external odors.

With the development and progress of society, environmental awareness has deeply penetrated people's hearts, and people's environmental requirements for packaging materials are increasing. PVA films with excellent performance and biodegradability are receiving more and more attention and application. PVA flexible packaging films have broad market prospects for development and application in China. It is understood that the production of PVA films is mainly concentrated in Japan, accounting for about 75% of the world's production, Domestic enterprises have a relatively low market share.

Wanwei High tech is the only domestic enterprise with the ability to produce biomass PVA. It currently has an annual production capacity of 100000 tons of biomass vinyl acetate and 50000 tons of biomass PVA product production equipment. In order to leverage the advantages of Wanwei High tech biomass products, expand the biomass alcohol vinyl acetate polyvinyl alcohol industry chain, occupy the high point of biomass PVA film production, and meet users' pursuit of green and environmentally friendly products, Wanwei High tech plans to raise funds to invest in the construction of a new biomass polyvinyl alcohol water-soluble film production line with an annual output of 20000 tons.

At present, the production process of biomass PVA water-soluble film by Anhui Weixin High tech has matured, and the pilot products have been exported to the market and are welcomed by users. It is now ready to expand the scale of construction. After the project is completed and put into operation, it can further enrich the product chain of Wanwei High tech and cultivate new profit growth points, which is conducive to the sustainable and high-quality development of Wanwei High tech. At the same time, it is also conducive to breaking the monopoly position of foreign product markets and expanding the influence of Anhui Wei's high-tech products in the international market.

In the announcement, Wanwei High tech stated that this project belongs to the category encouraged by national industrial policies, and the enterprise has the right to self operate import and export of products. After the implementation of the project, we can provide the market with the high-end biomass PVA water-soluble film products needed, while stabilizing the production and operation of the enterprise, ensuring social harmony, and meeting the requirements of the country's development of a harmonious society. According to market research analysis, the relevant products have a large market space, strong demand, and strong competitiveness, so policy risks are minimal.

In addition, on the same day, Wanwei High tech also issued a notice regarding investment in the construction of a 20kt/a multifunctional PVB resin project. According to the announcement, Wanwei High tech plans to self raise funds to invest in the construction of a 20kt/a multifunctional PVB resin project, with a total investment of 321 million yuan.

Polyvinyl butyral resin (PVB) is an extended product of the polyvinyl alcohol (PVA) product industry chain, which can be divided into film grade PVB and adhesive grade PVB. Among them, film grade PVB resin is processed into PVB film, mainly used for manufacturing laminated safety glass for automobiles and buildings. Adhesive grade PVB is mainly used as various adhesives in the fields of ink and electronic ceramics.

At present, the global market size of PVB resin has reached 13 billion yuan, and it is expected to reach 16.6 billion yuan by 2026, with a compound annual growth rate of 3.5%. About 79% of PVB resin is used in the production of safety glass in the construction and automotive industries, 14% is used in photovoltaic materials, and the remaining 7% is used in materials such as paint, glue, and dyes.

There are four major PVB manufacturers in the world, namely Solutia in the United States, Sekisui in Japan, DuPont in the United States, and Kuraray in Japan, which occupy 80% of the market share.

Wanwei High tech is the largest PVA production enterprise in China and the only domestic manufacturer with a complete industrial chain of "PVA-PVB resin PVB film". It independently produces specialized raw materials for PVB products and currently has an annual production line of 18000 tons of PVB resin and 22000 tons of PVB film. The ongoing construction of a 20000 ton annual production line for automotive grade PVB film will also be completed and put into operation in the second half of 2024. After years of production practice and technical breakthroughs, the PVB resin process technology has become increasingly mature, and the product quality has significantly improved, fully meeting the production technology requirements of architectural film, photovoltaic film, and automotive film. At the same time, we have successfully developed ultra-low viscosity PVB resin, PVB resin for electronic ceramics, and PVB resin for high-end inks, which have entered the customer trial stage.

Public information shows that Anhui wanwei updated high-tech material industry co.,ltd. is a subsidiary of Anhui Wanwei Group Co., Ltd. It is a major PVA manufacturer in China and has accumulated rich production and management experience in PVA, PVB resin, cast film and other fields.
