In the 80s and 90s of the last century, container bags were widely used in developed countries, and the bag manufacturer's bags started in 2001. Since then, with the steady growth of the export of chemical fertilizer and chemical products, Yixing, Zibo, Qingdao, Dezhou, Lianyungang, Dalian and Shenzhen have built up the production line of containerized bags. In the past 2005~2007 years, the first high speed growth period was ushered in the bag industry in China, with an annual increase of more than 20%. From the second half of 2008 to the first half of 2013, the global economic growth slowed down and exports were blocked by the financial crisis. Overseas demand for containerized bags decreased significantly, and the annual growth rate of domestic container bags decreased to less than 12%. After the second half of 2013, China's foreign trade increased steadily, thanks to the steady growth of China's economy, the strong rebound of the US economy and the fact that the euro zone basically got rid of the debt crisis. In particular, China launched a series of loose policies to promote the development of foreign trade, which greatly promoted the export of chemical fertilizers, coke and carbon black, and effectively increased the demand for containerized bags. The demand for pack bags is also expected to be on a further step by the local market pack manufacturers in the Midwest. This group of Wei stressed that to do value-added urea and urea tons of bags packaging market research and development, increase the added value of the products.

"At present, a 50 kilogram woven bag purchase price is more than 2.7 yuan, and the ton urea packaging cost is nearly 60 yuan. The labor cost of the packaging line and shipping process is higher than that of the container bag. As far as production efficiency is concerned, the packing bag packing is loaded and unloaded with forklift or small crane, and the time consuming is more than 1/3 in smaller bag package. In the past, the supply of bags could not be implemented because of the subcontracting of rural land to the household. With the implementation of the rural land transfer system and the formation of intensive management, the packing bag fertilizer has been promoted. We hope to take the lead in carrying out the collection bag urea attempt in the western region, and seize the opportunity. " Relevant responsible person said Wei group. "On the one hand, the export situation is better, on the other hand is the steady growth in domestic demand, coupled with the surge in demand for container volume on the central and western regions, we have reason to believe, can significantly improve the handling efficiency and reduce the cost of packaging and shipping container bags enterprises, will get more and more market share. In the next 5~10 years, the annual growth rate of the industry is expected to rise to more than 15%, entering the second rapid growth period. " Shaanxi Weinan Plastic Technology Co., Ltd. executive director, general manager Sun Zhongke said confidently.

"Our products have been in short supply, and many customers need to wait in line to pick up the goods." As the demand for pulverized coal and the demand for the export of chemical fertilizer bags has increased, almost all the packing - bag enterprises have to work overtime continuously.

"Our container bag manufacturers products mainly for Japan Kao Group packaging, annual output of 500 thousand. Due to the global Kao Group to accelerate the pace of expansion, our products have been in short supply, are full of the annual task." Wang Chunli, the general manager of Yixing Yuan Sheng Packing Products Co., Ltd., said. In addition, including Changzhou Hengcheng Plastics Machinery Co., Ltd. chairman Kan Shunyuan, general manager of Changzhou chuangcheng Plastic Machinery Co. Ltd. assistant Chai Huirong many people in the industry, the bag is optimistic about the prospects.

The export of container bag manufacturers led to the reproduction of high growth

According to Chai Huirong introduction, also called container bags, tons of bags, is capable of holding 0.5 to 3 tons of goods, plastic woven bag, usually consists of three folding wire or plastic extrusion woven, the strength of ordinary plastic bags more than 2 times. According to the quality of the goods, the bags can be divided into 0.5, 1, 1.5, 2, 2.5 and 3 tons specifications. According to their performance, they can be divided into general container, functional container and special way bag. According to the quality grade, they can be divided into high, medium and low grade. Among them, the high-end container bag for functional or special container bags, container bags such as for packaging food, medicine, cosmetics and other goods, the bag strength, weather resistance, especially health requirements higher, the price is usually up to 100 ~ 300 yuan /; in the end product mainly refers to container bags of fertilizer, polyolefin, soda and other chemical products required for the price of about 60 ~ 85 yuan / bar; strength, appearance, health and other indicators of low-end container requirement low, mostly for the import and export of iron ore, aluminum, aluminum, iron ore and other metal packaging, the price is usually less than 55 yuan / bar.

The central and Western warming is expected to become a new engine. The warming of the bag market has also led to a rapid rise in the construction of the central and Western packaging bags. "At present, the annual capacity of the national pack bag is about 70 million, mainly concentrated in the eastern region. Because 80% of the urea, ammonium phosphate, ammonium sulfate, ammonium chloride, ammonium nitrate fertilizer production concentrated in the Midwest, caustic soda, soda ash, PVC, coke and other heavy chemical products are mostly concentrated in the Midwest, so with the Midwest economy especially the rapid growth of foreign trade, the Midwest is expected to become the new engine driving the rapid development of the industry container bags." Kan Shunyuan said.

It is understood that the manufacturers FIBCs yuan chemical group following the 2013 attempt to use PVC container bags, tons of bags will increase the proportion of PVC this year; Shaanxi Xinghua group is considering exporting ammonium nitrate to use all container bags.
