| The work aims to review the research status and application progress of polymer-coated metal packaging, and explain the principles and characteristics of polymer-coated metal packaging technology. Metal packaging plays a dominated role in food packaging because of its excellent processing and mechanical properties, but the corrosion phenomenon of metal substrates undermines the quality of packaged contents. Polymer-coated metal has the characteristics of good corrosion resistance, low cost and environmental protection, so it has huge advantages in food and beverage packaging. From the process technology of polymer-coated metal, the work introduced the current research status of metal coating technology and analyzed the factors that affect its bonding strength to reduce defects through polymer modification and surface treatment of metal substrates, and thereby improve the quality of polymer-coated metal. The polymer-coated metal process is widely used in food packaging. By referring to previous experimental research results, analyzing the problems in the process and synthesizing the polymer-metal bonding mechanism during the coating process can provide support for further innovative research and application of metal coating technology. |
