The role of adhesives in the packaging industry

Adhesives are non-metallic substances that can transfer the surface of the same or dissimilar materials, and can fulfill certain physical and chemical properties. Adhesives, also known as adhesives, adhesives and adhesives, are simply called glues.
At present, there are more than 1,500 adhesives production enterprises in China, with more than 3,000 varieties, and it has become one of the fastest-growing key industries in China's chemical industry.
The application of adhesives has soaked into all areas of the national economy. Especially for the packaging industry, adhesives are everywhere and everywhere. In many cases, the adhesive can effectively replace some of the mechanical connections and the seams at the interface, which provides a very effective way to simplify the process, save energy, reduce costs, and increase economic efficiency in the packaging production process.
As adhesives play an indispensable role behind the scenes in the entire packaging industry, they have significant and far-reaching impacts on technological advances in packaging and related industries as well as product development and renewal. Therefore, the research, development and production of new types of adhesives with more assured quality and superior performance have become the research fields and scientific research activities that the packaging industry is paying more and more attention to.
Adhesives are adhesive-based agents, formulated with various curing agents, plasticizers, fillers, solvents, preservatives, stabilizers, and coupling agents. Most of the earliest adhesives used were derived from natural substances such as starch, dextrin, bone glue, and fish glue. Only water is used as a solvent, and it is formulated into glue by heating, because its composition is single and its applicability is poor. It is difficult to meet the needs of various uses. With the advent of synthetic polymer compounds, people have developed synthetic resin adhesives. For a variety of bonding applications. 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 ways to classify adhesives. According to the application methods, they can be divided into thermosetting, hot-melting, room-temperature curing, pressure-sensitive, etc.; they can be divided into structural, non-configured, or specialty adhesives depending on the application; Type, emulsion type, solvent type, and various solid-state types.
The continuous and rapid development of the world's industrialization has almost driven the continuous advancement of the entire industrial industrial chain. Adhesive industry as an independent industry, but also as a special auxiliary industry of the packaging industry, its development status and future development direction has become the focus of attention.
Since the 1950s, the adhesives industry has been developing at an extraordinary rate. The ever-increasing development of new products and the introduction of new and high-tech technologies continue to fill the current gap. At the same time, it has also promoted the continuous development of the entire industry itself, resulting in more and more extensive application fields as well as deeper professionalism. Refine the industry.
From the adhesive application structure, we can see that the packaging industry has always been the largest industry for adhesives. It is widely used in the internal twigs of the packaging industry for paper products, printing and decorating, and plastics. It has greatly promoted The packaging industry has developed rapidly and prosperously.
With the rapid development of the packaging industry, the market has increased the demand for adhesives, and at the same time has also considerably improved the quality and grade requirements of adhesives. It can be said that the adhesives industry and the packaging industry are two intimate and independent industries that are both independent and mutually dependent. Both parties are motivated and promote each other.
In the mutual guidance of the subtle interaction between water and milk, the packaging industry has promoted the advancing and development of the adhesive industry toward even more lofty goals; thus, the adhesive industry has also exerted a far-reaching impact on the packaging industry.
With the continuous improvement of people’s living standards and the continuous improvement of their own quality of life, coupled with the world’s common appeal for green environmental protection in recent years, people’s environmental protection and self-protection concepts have been continuously strengthened. In particular, daily necessities and food necessary for daily life are more focused on 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. In this way, they can move forward unimpeded.
It can be seen from this that the future development trend of adhesives must be based on the theme of “green environmental protection” and promote green harmony in the process of production R&D.
Since the adhesive industry was formed from the very beginning, the development speed has been fierce, and the entire industry has continued to grow and thrive 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 of many fields in related industries, such as in the packaging industry.
I believe that with the continuous advancement of science and technology, continuous research and development 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 promote more extensive Industry links, pioneering new and refined areas, bring more practical convenience to the improvement of human living standards.
