PO film (polyethylene oxide film) can be used as an agricultural film, and high-end development has become the mainstream trend in the industry.

​​ ​​Polyethylene oxide film, also called PO film, refers to a film made of ethylene, propylene or high-grade olefin polymers as raw materials and using an external spraying and drying process. PO film has the advantages of good thermal insulation, long service life, high transparency, anti-static, high tensile strength, good thermal insulation, acid and alkali resistance, etc. It is widely used in transportation, agriculture, medical and health, water conservancy projects and other fields.

PO film production is less difficult and the technical barriers to the industry are low. Its main production processes include raw material preparation, extrusion blow molding, surface treatment, soaking, drying, winding, packaging, etc. But at present, Chinese companies focus on the production of mid- to low-end PO films. The production cost of high-end PO films is relatively high and the market share is low. In the future, as local companies continue to exert their efforts, my country’s PO film industry will gradually develop in a high-end direction.

According to the “2023-2028 China PO film (polyethylene oxide film) industry market in-depth research and development prospect forecast report” shows that PO films are widely used in transportation, agriculture, medical and health, water conservancy projects and other fields, among which the agricultural field is the largest demand end. my country is a major agricultural country with a rich variety of crops and a huge planting area, which has driven the growing market demand for agricultural films. In 2022, my country’s agricultural film market will reach 38.67 billion yuan, a year-on-year increase of 4.6%. With the accelerated development of the agricultural film industry, PO film’s market share continues to increase due to its advantages such as long service life and high cost performance.

The global PO film market is mainly concentrated in Japan, South Korea and European and American countries. Representative companies include Exxon Mobil of the United States, Sumitomo Chemical Co., Ltd. of Japan, CAI Chemical Co., Ltd. of Japan, and Nissin Chemical Industry Co., Ltd. of South Korea. Corporation, South Korea’s Hanwha Group (Hanwha), etc. Japan is the first country in the world to develop and produce PO films. The Jinghua PO agricultural coating film launched by Sumitomo Chemical has the advantages of good light transmittance, long service life, and excellent thermal insulation performance. It is widely used in agricultural greenhouses.

my country’s PO film industry started late, but is developing rapidly. The main manufacturers include Kelun Co., Ltd., Shenyang Chemical Industry, Guofeng New Materials, Dongda Plastics, Mingfeng Plastic Film, Luguan Plastics, etc. Kelun Co., Ltd. focuses on the R&D, production and sales of agricultural mulch films and shed films. Light-converting PO films, highly transparent PO films, diffuse scattering PO films, etc. are the company’s main PO film products. According to the semi-annual report of Kelun Co., Ltd., in the first half of 2023, the company achieved revenue of 120 million yuan, a year-on-year increase of 15.6%.

​​  Industry analysts said that as an agricultural film, PO film has high cost performance and application demand continues to grow. At present, Chinese companies focus on the production of mid- to low-end PO films, and high-end products rely on imports. In the future, with technological progress, the market share of domestically produced high-end PO films will increase. In terms of market competition, there are many PO film manufacturers in my country. Kelun Co., Ltd., as a representative enterprise, has the production strength of various types of products.
