Stretch film manufacturing

Refers to the manufacture of agricultural, industrial, commercial and daily packaging films.

Include：

Industrial thin films: blown film, calendering film, stretch film, salivation film, etc.

- agricultural use of film, Stretch film and so on;

Packaging film (including medical packaging composite membrane, food packaging composite membrane, etc.).

Barring：

- the production of all kinds of plastic reproductions, such as raincoats made of stretch film, etc., is included in the 3082 (daily plastic grocery manufacturing).

The production of plastic pellets is included in 4320 (processing of non-metallic waste and debris).

Development status 

With the development of the economy and the adjustment of the rural industrial structure, the market demand for stretch film in all walks of life in China has been increasing.

In 2005, the total industrial output value of all plastic film production and supply enterprises in the whole country reached 79 billion 910 million 504 thousand yuan, 29% more than that of the previous year, and the total number of enterprise units was 1223. The total product sales revenue was 77 billion 417 million 653 thousand yuan in the year, 25.89% more than the same period of last year, and the total amount of total profit reached 2 billion 384 million 871 thousand yuan. The per capita sales rate of the industry is 488266.94 yuan.

In the first half of 2006, the total industrial output value of all plastic film production and supply enterprises in the whole country reached 43 billion 959 million 811 thousand yuan, up 17.31% over the same period of the previous year. The total number of enterprise units was 1299, and the total product sales revenue was 44 billion 40 million 148 thousand yuan, up 22.11% over the same period of the previous year, and the total total profit reached 1 billion 213 million 127 thousand yuan. The per capita sales rate of the industry is 889069.85 yuan. Overall, the national plastic film production and supply business is in good condition.

China's plastic film production accounts for about 20% of the total output of plastic products. It is one of the fastest growing categories of plastic products. From the application field of stretch film (0.06mm to 0.26mm thickness) in China, the packaging industry has the largest consumption, most varieties and the most widely used. Its consumption is about 2/3, next is about 30% of agriculture, and then the functional membrane, such as microporous membrane, shielding film and geomembrane. In theory almost all synthetic resins may be films, but the most economical, commercial, and most used are polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS), ethylene / vinyl acetate (EVA), polyamide (PA) and other resins. . If suitable plastic additives are added to the resin matrix, all kinds of functional films can be prepared. The production methods of plastic film industry include extrusion and extrusion, in which extrusion is divided into extrusion blowing, extrusion casting, extruding and stretching (also called two molding). At present, the extrusion method is the most widely used, especially for the processing of polyolefin shrink film, and the calendering method is mainly used in the production of stretch film.

China's stretch film industry is at a stage of vigorous development. It is reported that the demand for stretch film in China will grow by more than 9% annually. And with the continuous emergence of new materials, new equipment and new technology, China's stretch film will be developed in the direction of variety, specialization and multi-functional composite membrane.

With the development of China's economy and the adjustment of rural industrial structure, the market demand for plastic film in all walks of life in China has been increasing. At present, China's stretch film production accounts for about 20% of the total output of plastic products, and it is one of the fastest growing categories of plastic products. Global consumption of plastic film and sheet market is expected to reach 50 million 700 thousand tons in 2015, and the Asia Pacific region is expected to become the fastest growing regional market. The plastic film industry in China is currently in a flourishing stage. The average annual growth rate of the 2001-2011 year market is over 18%, and it is expected to reach 350 billion yuan in 2012.

With the development of the industry, the competition of the plastic film manufacturing industry is increasing. The excellent stretch film production enterprises in China pay more and more attention to the research on the industry market, especially the deep research on the industry development environment and the buyer of the products. It is also because of this, a large number of excellent domestic plastic film manufacturing brands rapidly rise, gradually become China and the world's stretch film industry in the world's top!

At present, there are few enterprises producing thin film photovoltaic products in China. Thanks to the country's policy and fund support to the new energy industry such as solar energy, China's solar cell industry has developed rapidly in 2011, and 6 of the world's ten largest solar cell manufacturers are in the world.
