Adhesives refer to non-metallic substances that can tightly connect the surfaces of the same or dissimilar materials, play a transfer role, and meet certain physical and chemical performance requirements. Adhesives are also called adhesives, adhesives and adhesives, etc., and are referred to as glues for short.

At present, there are more than 1,500 adhesive manufacturers in my country, with more than 3,000 varieties, and it has become one of the fastest-growing key industries in my country's chemical industry.

The application of adhesives has penetrated into all areas of the national economy. Especially for the packaging industry, the presence of adhesives can be seen everywhere. In many occasions, adhesives can effectively replace some mechanical connections and adhesion stitching at the interface, providing a very effective way to simplify the process, save energy, reduce costs, and improve economic benefits in the packaging production process.

Because adhesives play an indispensable behind-the-scenes role in the entire packaging industry, they have a significant and profound impact on the technological progress of packaging and related industries, as well as product development and update. Therefore, the research, development and production of new adhesives with better quality and better performance have become a research field and scientific research activity that the packaging industry is paying more and more attention to.

Adhesives are made from adhesives as the main agent, with various curing agents, plasticizers, fillers, solvents, preservatives, stabilizers and coupling agents. Most of the earliest adhesives were derived from natural substances, such as starch, dextrin, bone glue, fish glue, etc. Only water is used as a solvent, and the glue is prepared by heating. Because of its single composition, the applicability is poor. It is difficult to meet the needs of various uses. With the emergence of synthetic polymer compounds, people have developed synthetic resin adhesives. It can be used in various bonding occasions. In recent years, with the improvement of the level of material development and the advent of various modified resins, the performance of synthetic resin adhesives has been further improved.

There are many classification methods for adhesives. According to the application method, they can be divided into thermosetting, hot melt, room temperature curing, pressure sensitive, etc.; according to the application object, they can be divided into structural, non-configuration or special adhesives; bonding forms can be divided into water-soluble Type, water emulsion type, solvent type and various solid type, etc.

The continuous and rapid development of industrialization in the world has almost driven the continuous advancement of the entire industrial chain. As an independent industry, the adhesive industry is also a special auxiliary industry of the packaging industry. Its development status and future development direction have become the focus of attention.

Since the 1950s, the adhesive industry has been developing rapidly at an unconventional rate. Increasingly researched and developed new products and the advent of related high-tech are constantly filling the current gaps, and at the same time promoting the continuous development of the entire industry itself, deriving more and broader application fields and deepening into more professional Refine the industry.

We can see from the adhesive application structure that the packaging industry has always been the largest industry for adhesive applications. It is widely used in the internal twigs of the packaging industry such as paper products, printing and decoration, and plastics, which has greatly promoted The packaging industry is booming and developing rapidly.

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 raised to a considerable extent. It can be said that the adhesive industry and the packaging industry are two intimate industries that are both independent and interdependent. The two sides are each other's driving force and mutual promotion.

With the subtle mutual guidance of water and milk, the packaging industry has promoted the adhesive industry to advance and develop towards a higher goal; in this way, the adhesive industry has also had a more profound impact on the packaging industry.

With the continuous improvement of human living standards and the continuous improvement of their own quality of life, coupled with the common appeal of the world for green environmental protection in recent years, people's concepts of environmental protection and self-protection have been continuously strengthened. Especially for the daily necessities and food necessary in daily life, we pay more attention to environmental protection.

As an important member of packaging materials, packaging adhesives should cater to the needs of social development and highlight their own green environmental protection, so that they can develop unimpededly.

It can be seen that the future development trend of adhesives is bound to take "green environmental protection" as the theme, and promote green harmony in the process of production and research and development.

Since its inception, the adhesive industry has developed rapidly and violently, and the entire industry has continued to innovate and thrive under the strict test of the market. At the same time, in the process of its own development and improvement, it has also promoted the innovation and development of many fields in related industries. For example, in the packaging industry, the performance is even more vivid.

I believe that with the continuous advancement of science and technology, the continuous development and creation of new technologies and new products, the closer cooperation between the adhesive industry and the packaging industry will surely create more social and economic benefits for the society and drive a wider range of Industrial links have opened up newer and refined areas, bringing more practical convenience to the improvement of human living standards.
