Now the main adhesives on the market are divided into water-based adhesives, solvent-based adhesives, and hot melt adhesives, each of which has its own unique characteristics. Solvent-based adhesive mainly uses organic solvent as solvent, the main characteristics are high bonding strength, good water resistance, high volatility, greater pollution and other characteristics. With the promotion of environmental protection in recent years, people are more aware of the harm caused by solvent-based adhesives. The hot melt adhesive has the outstanding advantages of environmental protection, safety, rapid curing, suitable for automated production, etc., and in the past ten years, hot melt adhesive has been one of the fastest growing adhesive varieties.
With the rapid development of the adhesive industry, the application of hot melt adhesives can be seen in more and more industries, such as the automotive industry, packaging industry, label industry, home appliance and furniture industry, food and beverage industry, daily necessities industry, etc. At the same time, in order to meet the process requirements of different industries, there are more and more types of hot melt adhesives, which are used in different industries according to different performance, and are also known as label hot melt adhesives, automotive hot melt adhesives, furniture edge sealing adhesives, packaging hot melt adhesives, labeling adhesives, etc., which are suitable for the needs of the industry.
Hot melt adhesive has the advantages of high strength, strong toughness, long shelf life and fast bonding, and can be described as the star product of recent adhesives. Whether it is adhesion to metals, ceramics, wood, electronics, glass, plastics, leather, jewelry, crafts, building products, etc., hot melt adhesives can be used to bond. In fact, China's hot melt adhesive industry has entered a stage of rapid growth in the past two decades after early market accumulation and technology precipitation. As the main type of adhesive, hot melt adhesive has developed greatly in China, and China has now become one of the main production bases of hot melt adhesive in the world. Therefore, for industrial production, hot melt adhesive is a direction for the development of adhesives in the future.
In fact, environmental protection is a global topic and a common focus of attention in various industries. Taking the packaging industry as an example, China's flexible packaging industry has grown rapidly in recent years, and the impact on health and environmental protection has become increasingly prominent, among which adhesives for flexible packaging have always been one of the core issues discussed. Therefore, the application prospects of environmentally friendly hot melt adhesives in this industry are very broad.
At present, with the increasingly strict environmental protection law and the continuous enhancement of people's awareness of environmental protection, environmentally friendly adhesives have become the mainstream of the development of synthetic adhesives in China. Hot melt adhesive technology is a new technology, new material and new process full of vitality, which has created superior conditions for the modernization of the national economy (automation, high-speed, continuity) and has a promising future.
