Tabarestan Plastic Complex (TPC) was established in 1996 and started producing on a land with an area of 8500 square meters in the green historical city, called Sari, in the North of Iran in 1998. A development plan was made and operated on a land with an area of 9100 square meters in Shiraz in 2001 so as to support the markets in the south of the country and reducing the costs of transporting the products. In 2005 the process of improvement in the technological area attracted the company managers' attention and the search to identify and perform a development plan started in this direction. So the Complex bought an advanced production line equipped with a modern technology imported it in Iran in 2006 and the second site of the Tabarestan Plastic Complex has started to work on a land with an area of 17000 square meters in Sari. In the same year, the research and development unit of the company was equipped with the only laboratorial machine of Iran rotomolding industry and some activities were followed more seriously to do researches and create knowledge within the TPC. In 2011 two new development plans were performed and operated in Sari and Shiraz. Now theTPC - with more than 200 employees, 9 production lines and the production capacity of more than 8000 tons a year – is the largest manufacturer of rotomolding products in Iran.
