What is a Composite Tape?

In 1928 in St. Paul, Minnesota, Richard Drew invented scotch tape. According to its effectiveness, tape can be divided into: high-temperature tape, double-sided tape, insulating tape, special tape, pressure-sensitive tape, die-cut tape, different functions are suitable for different industry needs. A layer of adhesive is applied to the surface of the tape to make the tape stick to the article. The earliest adhesives came from animals and plants. In the nineteenth century, rubber was the main component of adhesives; modern polymers are widely used.

1928 Scotch tape Richard Drew, St. Paul, Minnesota, USA. May 30, 1928. Applying in the United Kingdom and the United States, Drew developed a very light, one-touch fit.

Tape is made of

Divided according to the substrate: can be divided into BOPP tape,

There are many types of tapes, and the adhesives on their surfaces are also different.

The ordinary packing tape (BOPP biaxially-oriented polypropylene) in daily life is an indispensable daily product in any enterprise, company, or individual life. However, compared with the current domestic situation, although there are many manufacturers, the technology is uneven . In addition, the technical content of the domestic tape industry is still at a very low level, and the country still does not have a clear choice for this. People often understand the tape at a very ignorant stage, thinking that the price is low and the viscosity is good. In fact, these are wrong understandings and judgments.

So how to choose the quality of the tape? In fact, there are two standards for the quality of the adhesive tape in use, one is initial adhesion, and the other is retention. The two are inversely proportional. In general, adhesive tapes with a viscosity less than 10 are less coated with glue, generally only about 20 microns, such as stationery tapes, ordinary promotional binding tape. The initial adhesion of normal sealing tape is between 15-20, and the thickness of this tape is generally 22-28 microns. Is standard thickness. However, most of the tapes on the market are doped with impurities, so the thickness is increased. To mask the impurities, the glue is also doped with color powder, so the transparent tape appears egg yellow and light green. This tape is generally inferior.

How to distinguish between colored tape? For colored tape, it is generally compared with yellow and khaki.

When peeling off the tape, it is easy to stick down the surface items such as the wall because of the stickiness of the tape. At this time, after only ironing with a steam iron, the stickiness of the tape will be reduced. Take it off without damaging things like walls.

With the development of economy and technological progress, China has become a processing and production plant and a big consumer in the world's adhesive industry. Combining years of supporting experience. It is growing at a rate of 16% per year. In particular, adhesive tapes, protective films, and stickers are widely used in electronics, communications, packaging, construction, papermaking, woodworking, aerospace, automotive, textile, metallurgy, machinery manufacturing, and medical industries. The adhesive industry has become China's chemical industry The most dynamic and important industry in the industry. ^[1]

The development of the belt industry mainly depends on the development of coal, steel, cement, ports, mines, petroleum, automobiles, textiles, light industry, machinery and other industries. Since the "Eleventh Five-Year Plan" period, China's national economy has continued to develop rapidly, which has led to the sustained and rapid growth of coal, steel, cement, automobiles, and agricultural machinery. China's coal, steel, and cement output ranks first in the world. At the same time, the state has taken measures to increase domestic demand and is expected to continue to implement it for a long time. It will undoubtedly also drive the development of industries such as building materials, automobiles, agricultural machinery, and light industry. In addition, the emphasis on "agriculture, rural areas and farmers" will also be carried out over a long period of time, which has opened up a broad and long-term potential market for China's tape work. Automotive tape is the fastest-growing variety, which is closely related to the rapid development of China's automobile industry. The automobile industry is the pillar industry of China's national economy. In 2009, China's automobile production and sales reached more than 13 million vehicles, ranking first in the world. In the first eight months of 2010, China's automobile production and sales exceeded 11 million units, setting a new historical high and leapfrogging into the world's largest automobile consumer. According to the prediction of China Machinery Industry Federation and China Automobile Industry Association, the production and sales of automobiles in China will exceed the 16 million mark in 2010. The growth rate of automobile production and sales will slow down in the next few years, but will remain above 10%. After more than 50 years of development, the Chinese automobile industry has basically established a relatively complete automobile industry production system. Driven by the reform and opening up policy, and stimulated by the strong domestic market, it has achieved rapid development. China s automobile and parts exports It also shows a rapid development trend, with an average annual growth rate of nearly 50% from 2001 to 2009. In 2009, auto product exports reached more than 30 billion US dollars. The international comparative advantage of China's auto products still exists, and the potential of international market demand is huge. The output value of flame-retardant conveyor belts and V-belts consumed by the coal industry is expected to increase by double digits each year. The petroleum industry is one of the important industries of the national economy. It has developed steadily with an annual oil growth rate of about 7%. In particular, the exploitation of offshore oil wells will increase the demand for tapes. As China's infrastructure construction speeds up, construction machinery continues to increase. Every year, China's construction machinery, including loaders, rollers, graders, excavators, etc., has an output growth of about 10%, and the demand for various major construction machinery is more than 100,000. It is expected that a large number of construction machinery will be needed in recent years, which will bring significant opportunities for the use of construction machinery supporting tape. With the increase of the degree of agricultural mechanization in China, the output of agricultural machinery is increasing year by year, and the tape for agricultural machinery is also a big market.
