PPGI was born in the United States last 30s.and originated to china in the late 1980 s. It developed rapidly in the past decades, until 2005, it became to surplus. After the adjustment from the economic crisis in 2008, PPGI was revived.
There have three reasons why PPGI industry was decaying.
1. The product model have no uniform standard, specification, lead to a lot of waste, and left the serious environmental problems;
2. The quality of coating made us loss the competitiveness with import PPGI especially many small factories in order to reduce cost, use inferior coating,it made them worse.
3. The last reason is over capacity.Reasons lead to decay . but in recent years, many factories make the positive adjustment: improve the processing technology, perfect production equipment, improve the quality of basal plate, control the process, research and development of new products, pay attention to diversity, after all PPGI is getting the new life.
