my country’s coating film industry has good development prospects and great potential for market demand growth.
According to the different coating layers, coating films can be divided into PVOH coating films, PVA coating films, acrylic coating films and PVDC coating films; according to different substrate films, coating films can be divided into BOPP coating films Film, BOPET coated film, BOPA coated film, CPP coated film, CPE coated film, etc.; depending on the coating surface, coated films can be divided into single-sided coated films and double-sided coated films.
At this stage, flow coating technologies mainly include wire roller coating, smooth roller coating, blade coating, comma blade coating, extrusion coating and curtain coating, etc. Among them, screen roller coating is suitable for solvent-based adhesives with low concentration and high drying capacity. The coating film is smooth and there is no coating leakage. Smooth roller coating achieves the purpose of coating by transferring coating liquid from roller to roller. This coating method usually uses two roller transfer coating. The coating is usually controlled by adjusting the gap between the upper rubber roller and the coating roller. quantity. The comma scraper is one of the new coating methods. As one of the key components of the coating head, the comma scraper has advantages that other scraping equipment does not have.
Compared with leading foreign developed markets, my country’s coating film industry has problems such as overcapacity of low-end products, insufficient supply of high-end products, structural supply and demand contradictions of products, and obvious problems such as product homogeneity among small and medium-sized enterprises. At this stage, there are a large number of companies in China’s coating film industry, and competition in the industry is fierce. Representative companies in the industry include Yunnan Enjie New Materials Co., Ltd., Jiangsu Sticky New Materials Technology Co., Ltd., and Ningbo Jizhi Technology Co., Ltd. Company, Guangdong Laier New Material Technology Co., Ltd., etc.
According to the “China Coated Film Industry Market In-depth Assessment and 2023-2027 Investment Feasibility Consultation Report” released by the Industrial Research Center , the main sources of demand for coated films are concentrated in industries such as food packaging, consumer electronics, automotive electronics, LED lighting, semiconductors, and communication cables. In recent years, environmental protection policies have tightened, and the product packaging industry has developed in a green, low-carbon, and sustainable direction. Coated films are more in line with the development direction of the packaging industry, which is conducive to the continued increase in demand for coated films.
Industry analysts said that in the future, with the changes in downstream product packaging requirements, the barrier properties, heat sealing properties, and As performance such as printability is optimized, more and more coated film products will be developed, which will drive a rapid increase in demand for coated film products.
