The role of adhesives in the packaging industry

adhesives refer to non-metallic substances that can closely connect the surfaces of the same or different materials, play a transfer role, and meet certain physical and chemical performance requirements. Adhesives, also known as adhesives, adhesives and adhesives, are called adhesives for short. At present, there are more than 1500 adhesive production enterprises in China, with more than 3000 varieties. It has become one of the key industries with the fastest development in the field of chemical industry in China. The application of adhesives has penetrated into various fields of the national economy. Especially for the packaging industry, the use principle of Leeb hardness tester can be seen everywhere and everywhere. In many cases, adhesive can effectively replace some mechanical connections and adhesive stitching at the interface, which provides a very effective way to simplify the process, save energy, reduce costs and improve economic benefits in the packaging production process. Adhesive plays an indispensable role in the whole packaging industry, and has a significant and far-reaching impact on the technological progress of packaging and related industries as well as the R & D and updating of products. Therefore, the pace of research, development and innovation of manufacturing enterprises should also be accelerated. The development and production of new adhesives with more guaranteed quality and superior performance have become more and more concerned research fields and scientific research activities in the packaging industry. The adhesive is prepared with adhesive as the main agent and various curing agents, plasticizers, fillers, solvents, preservatives, stabilizers, coupling agents and other additives. Most of the earliest used adhesives came from natural substances, such as starch, dextrin, bone glue, fish glue, etc. Only water is used as solvent, and the glue is prepared by heating. Because of its single component, its applicability is poor. It is difficult to meet the needs of various applications. With the emergence of synthetic polymer compounds, synthetic resin adhesives have been developed. It can be used for various bonding occasions. In recent years, with the development of materials and the advent of various modified resins, the properties of synthetic resin adhesives have been further improved. There are many classification methods for adhesives, which can be divided into thermosetting type, hot melt type, room temperature curing type, pressure-sensitive type, etc; It can be divided into structural, non structural or special adhesives according to the application object; The connection forms can be divided into water-soluble type, water emulsion type, solvent type and various solid types. The continuous and rapid development of world industrialization has almost driven the whole industrial chain forward. As an independent industry, adhesive industry is also a special auxiliary industry of packaging industry. Its development status and future development direction have become the focus of attention. Since the 1950s, the adhesive industry is developing rapidly at an extraordinary speed. The increasingly developed new products and the advent of relevant high and new technologies constantly fill the current gap, and also promote the continuous development of the entire industry itself, resulting in more and more broad application fields and more specialized and detailed industries. From the application structure of adhesives in 2015, we can see that the packaging industry has always been the largest industry for the application of adhesives. It is widely used in the internal fine branches of the packaging industry such as paper products, printing and decoration, plastics and so on, which has greatly promoted the prosperous and rapid development of the packaging industry. With the rapid development of the packaging industry, the market demand for adhesives has increased, and the requirements for the quality and grade of adhesives have also been improved to a considerable extent. It can be said that the adhesive industry and the packaging industry are two closely related industries that are both independent and interdependent. Both sides are driving forces and promoting each other. In the subtle mutual guidance, the packaging industry has promoted the adhesive industry to advance and develop towards a higher goal; Thus, the adhesive industry also has a far-reaching impact on the packaging industry. With the continuous improvement of human living standards and the requirements for their own quality of life, coupled with the common appeal of the world for green environmental protection in recent years, people's concept of environmental protection and self-protection has been continuously strengthened. Especially for the daily necessities and food in daily life, we pay more attention to green environmental protection. As an important member of packaging materials, packaging adhesives should meet the needs of social development, highlight their own green will not be crushed and environmental protection, so that they can develop smoothly. It can be seen that the future development trend of adhesives is bound to take green environmental protection as the theme, and advocate green harmony in the process of production and R & D. The adhesive industry has developed rapidly and violently since its inception. The whole industry continues to grow vigorously under the strict test of the market. At the same time, in the process of self-development and improvement, it has also promoted the innovation and development in many fields of related industries, such as the packaging industry. It is believed that with the continuous progress of science and technology, the continuous R & D and creation of new technologies and new products, and the closer cooperation between the adhesive industry and the packaging industry, it is bound to create more social and economic benefits for the society, drive broader industrial links, open up new and detailed fields, and bring more practical convenience to the improvement of human living standards
