Heat shrinkable sleeve is a kind of non-metallic material which can connect the same or different materials closely, play a transmission effect, and satisfy the needs of physical and chemical functions. Heat shrinkable belt is also called adhesive heat shrinkable belt, adhesive heat shrinkable belt and adhesive heat shrinkable belt, and so on.
At that time, there were more than 1500 heat shrinkable belt production companies in China, with more than 3000 kinds of types, which had become one of the key jobs in the field of chemical industry in China.
The application of heat shrinkable belt has penetrated into various categories of national economy. Especially for the packaging industry, the figure of heat shrinkable belt can be seen everywhere. In many cases, the heat shrinkable belt can replace some mechanical connection and the adhesion suture at the interface, which provides a very useful method for simplifying the process, saving energy, reducing costs and improving economic benefits in the packaging production process.
Because the heat shrinkable tape plays an indispensable role in the whole packaging industry, and has a serious and far-reaching impact on the technical progress of packaging and related industries and the development and renewal of products. Therefore, the research, development and production of all kinds of new heat shrinkable belts with more guaranteed quality and better functions have become the research areas and scientific research activities of packaging industry.
The heat shrinkable belt is made of adhesive based heat shrinkable belt, cooperated with various curing heat shrinkable belt, plasticized heat shrinkable belt, filler, soluble heat shrinkable belt, anticorrosive heat shrinkable belt, stable heat shrinkable belt and coupling heat shrinkable belt. Most of the heat shrinkable bands used earlier are from natural materials, such as starch, dextrin, bone glue, fish glue, etc. Only water is used as the heat shrinkable belt and heated to produce glue. Because of its single composition, its applicability is poor. It is difficult to satisfy the needs of various uses. With the appearance of polymer compounds, we also announced the composition of resin heat shrinkable band. It can be used in various bonding occasions. In recent years, with the progress of the research and development of materials and the appearance of various modified resins, the function of resin heat shrinkable belt has been further improved.
There are many classification methods of heat shrinkable tape, which can be divided into thermosetting type, hot melt type, room temperature curing type and pressure sensitive type according to the application method; it can be divided into layout type, non configuration type or special adhesive according to the application policy; the connection shape can be divided into water-soluble type, water emulsion type, solution heat shrinkable belt type and various solid types.
With the rapid development of international industrialization, the whole industrial chain has been pushed forward. As an independent profession and a special auxiliary industry of packaging industry, the development status and future development direction of heat shrinkable belt have become the focus of attention.
Since the 1950s, the heat shrinkable belt industry is developing rapidly at an unconventional speed. The new products and the advent of related high-tech constantly filled in the blank at that time, and together promoted the whole profession to carry forward continuously, deriving more and more extensive application fields and deepening to a more detailed industry.
From the application layout of heat shrinkable tape, we can see that the packaging industry has always been a big industry for the application of heat shrinkable tape. It is widely used in the internal fine branches of the packaging industry such as paper products, printing and decoration, plastics, etc., which greatly promotes the prosperity and rapid development of the packaging industry.
With the rapid development of packaging industry, promote the market demand for heat shrinkable tape, and improve the quality and level of heat shrinkable belt to a certain extent. It can be said that the heat shrinkable belt industry and packaging industry are two closely related industries which are both independent and interdependent.
In the inseparable mutual guidance, the packaging industry promotes the development of the heat shrinkable belt industry to a higher policy; in this way, the heat shrinkable belt industry also has a far-reaching impact on the packaging industry.
With the continuous improvement of people's livelihood level and the continuous progress of their own livelihood quality needs, together with the international call for green environmental protection in recent years, the concept of environmental protection and self-protection has been strengthened. Especially for the daily necessities and food in daily life, we pay more attention to environmental protection.
As an important part of packaging materials, heat shrinkable tape for packaging should meet the needs of social development, and be outstanding in its own green environmental protection. Only in this way can we move forward smoothly.
Therefore, the development trend of heat shrinkable belt in the future must take "green environmental protection" as the theme, and advocate green harmony in the process of production and development.
From the beginning, the heat shrinkable belt industry has developed rapidly and strongly. Under the strict inspection of the market, the whole industry is constantly changing customs and thriving. Together, in the process of its own development and progress, it has also promoted the transformation and development of many related industries, such as in the packaging industry, which is more vivid.
Trust, in the future, with the continuous progress of science and technology, the continuous development and invention of new technologies and new products, the closer cooperation between the heat shrinkable belt industry and the packaging industry, will definitely create more social and economic benefits for the society, stimulate a wider range of industrial links, open up new and detailed categories, and bring more convenience to the progress of human livelihood.
