(plastemart) -- Indonesia's Tri Polyta's polypropylene plant, that has been shut for debottlenecking since March 2010, will see a delay in restart. Restart will be delayed by three months to April 2011, mainly on concerns on global economic recovery. The debottlenecking program will boost the plant's PP capacity -- across three production lines at Cilegon, Banten in west Java from 360,000 tpa to 480,000 tpa.
