With the development of the economy and the adjustment of the rural industrial structure, the market demand for plastic films in all walks of life in China has continued to rise.
In 2005, the cumulative total industrial output value of all plastic film production and supply enterprises nationwide reached 79,910,504 thousand yuan, an increase of 29% over the previous year. The cumulative number of enterprises was 1,223, and the annual cumulative product sales revenue was 77,417,653. Thousand yuan, an increase of 25.89% over the same period last year, and the total cumulative profit reached 2,384,871,000 yuan. The per capita sales rate of the whole industry was 488,266.94 yuan.
In the first half of 2006, the cumulative total industrial output value of all plastic film production and supply enterprises in the country reached 43,959,811 thousand yuan, an increase of 17.31% over the same period of the previous year. The cumulative number of enterprises was 1,299, and the cumulative product sales revenue was 44,040,148 thousand. Yuan, an increase of 22.11% over the same period of the previous year, and the total accumulated profit reached 1,213,127 thousand Yuan. The per capita sales rate of the whole industry is 889,069.85 yuan. On the whole, the operating conditions of plastic film production and supply enterprises nationwide are good.
The output of plastic film in China accounts for about 20% of the total output of plastic products, and it is one of the types of plastic products that has seen a rapid increase in output. From the perspective of the application fields of China's plastic film (thickness 0.06mm～0.26mm), the packaging industry has the largest consumption, the most variety, and the widest application. Its consumption accounts for about 2/3, followed by agriculture, which accounts for about 30%. It is functional membrane, such as microporous membrane, shielding membrane, geomembrane and so on. In theory, almost all synthetic resins can form films, but they have economic significance and become commercial products. The most used ones are polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), and polyethylene terephthalate. Ester (PET), polystyrene (PS), ethylene/vinyl acetate (EVA), polyamide (PA) and other resins. If appropriate plastic additives are added to the resin matrix, various functional films can be prepared. The production methods in the plastic film industry include calendering and extrusion. Among them, the extrusion method is divided into extrusion blown film, extrusion casting, extrusion stretching (also known as secondary molding), etc. The extrusion method is the most widely used. Widely used, especially for the processing of polyolefin films, and the calendering method is mainly used for the production of some polyvinyl chloride films.
China's plastic film industry is in a stage of vigorous development. It is reported that the demand for China's plastic film will grow at a rate of more than 9% every year. Moreover, with the continuous emergence of various new materials, new equipment and new processes, China's plastic film will develop towards the direction of diversification, specialization and multi-functional composite film.
With the development of China's economy and the adjustment of rural industrial structure, the market demand for plastic films in all walks of life in China continues to rise. It is predicted that the global plastic film and sheet market consumption in 2015 is expected to reach 50.7 million tons, of which the Asia-Pacific region is expected to become the fastest-growing regional market. China's plastic film industry is currently in a stage of vigorous development. The average annual growth rate of the market scale from 2001 to 2011 reached more than 18%, and it is expected to reach 350 billion yuan in 2012.
