History Of Packaging Adhesive Materials

In 1909, Belgian-American chemist Lech Baekeland invented industrial phenolic resin, marking the beginning of synthetic resin adhesives. In 1912, Baekeland demonstrated plywood bonded with phenolic resin. Before World War II, solvent-based natural rubber dominated the adhesive market. After the emergence of rubber adhesives in 1932, "rubber-based" adhesives gradually entered the market. Following World War II, new polymer materials emerged, ushering in the era of polymer chemistry. Research and development of synthetic rubber and synthetic resins became prevalent worldwide, leading to corresponding technological innovations in adhesives, such as the development of EVA hot melt adhesives and quick-drying adhesives.

The modernization of packaging materials in my country began in 1955 with the introduction of extrusion lamination technology developed in the United States, resulting in the development of composite films of cellophane and polyethylene. Subsequently, with the development of various films, dry lamination technology from Germany was introduced in 1965. In the early stages, adhesives used included vinyl acetate, vinyl ester, ethylene-vinyl acetate, and rubber-based adhesives. Later, due to the good processability and high bonding strength of polyurethane adhesives, polyurethane-based adhesives were almost exclusively used in plastic composites.
