Paint, also known as varnish, is a chemical mixture that firmly coats surfaces for protection, decoration, marking, and other special purposes. As we all know, with the continuous improvement of our economic level, home renovation has become extremely popular in our lives, and the use of paint has also gradually flourished. The packaging industry is a rapidly developing sector, and the annual growth rate of paint filling machines seems to be the highest among traditional industries. However, paint filling machines still face many problems during their development. Although my country's machinery level has greatly improved in recent years, there is still a gap compared with developed countries.

Paint filling machines are a product of the heyday of paint. With the development of the packaging industry, paint filling machines have also achieved certain developments. However, the difference between their advantages and disadvantages compared with developed countries is still very obvious. This is mainly reflected in the low level of paint packaging technology. The main reasons are that my country's paint filling machinery companies are relatively small and production is relatively scattered. In addition, due to various factors such as capital investment and corporate structure, many paint filling machine companies lack marketing experience.

Few domestic paint filling machine manufacturers can offer complete production lines, from packaging individual paint products to final packaging machinery. Most rely on patchwork from other manufacturers. This significantly lags behind advanced, integrated paint filling lines from abroad. An investigation revealed that domestic paint filling machines lag behind foreign counterparts in terms of technology, output, filling accuracy, and mechanical equipment operational stability. This gap is particularly pronounced for automatic and fully automatic paste fillers, which lag behind European products by at least ten years. Faced with these shortcomings, domestic paint filling machine manufacturers need to identify the causes, seize opportunities, and address challenges. They should strive for technological innovation, design, and after-sales service, ultimately bringing their R&D and production technology to world-leading levels.

Currently, the global trend in paint filling machine development is towards higher production efficiency, greater resource utilization, energy-saving products, practical application of advanced technologies, and commercialization of scientific research results. Consequently, intensified research on basic paint filling machine technologies in my country is urgently needed.
