In 2003, with the strategic objective of adding capacity closer to one of its main regional markets in South-East Asia, Polyplex set up a new plant with a capacity of 21,000 tons per annum at Rayong, Thailand through its subsidiary Polyplex (Thailand) Plc (PTL). In the same year, PTL added a second thin PET film line with a similar capacity and followed it up in 2004/2005 with the commissioning of a batch-process resin plant and a continuous-process resin plant, thereby making it completely self-sufficient in PET resin. In 2013, PTL has set up a Thick PET film line and batch resin plant in Rayong, Thailand adjacent to its existing facility with an annual capacity of 28,800 MT for the film plant and 28,000 MT for the resin plant.

In 2005, Polyplex extended its manufacturing footprint into Turkey, moving closer to the European and Mediterranean markets and firmly establishing Polyplex as a global company. Through its subsidiary Polyplex Europa (PE), a facility was set up in the European Free Zone at Çorlu, Turkey.

PE began with a thin PET film line with a capacity of 29,000 tons per annum and in 2006, a continuous process PET resin plant was added for meeting its captive requirements. Two co-generation power plants of 4 megawatts each were installed to provide greater power security for the facility. In 2008, a second thin PET film line with a capacity of 29,000 tons per annum was commissioned, taking the total capacity to 58,000 tons per annum of base thin PET film.

In September 2013, PE incorporated a 100% owned distribution subsidiary in Turkey by the name of POLYPLEX PAKETLEME ÇÖZÜMLERİ SANAYİ VE TİCARET ANONİM ŞİRKETİ to facilitate better market reach in the local Turkish market.

Americas account for about 12% of the world's consumption of thin PET film and has, since the 90's, been a significant market for Polyplex. In 1996, Polyplex moved closer to its North American customers through Spectrum Marketing, Inc., a joint venture based in Fort Worth, Texas, for warehousing and distributing Polyplex products. This entity was acquired in 2006 and renamed as Polyplex (Americas), Inc. In view of the growing American market demand and the absence of new PET film capacity, Polyplex decided to invest in the USA in 2011. Polyplex USA LLC, a wholly owned subsidiary of PTL, was incorporated and a green-field facility comprising a thin PET film line was started in April 2013 in Decatur, Alabama followed by the PET Resin plant in July 2014. In July 2012, Polyplex has acquired some metallizing assets located at Austell, Georgia and have relocated most of these assets to Decatur, Alabama while some had been shifted to other group locations. With effect from January 31st, 2013, Polyplex (Americas) Inc. has been merged with Polyplex USA LLC, Alabama.
