APMP: an Alternative for Packaging Industry

APMP process has been conventionally used to produce writing and printing papers. Maragheh Paper Industries Company (MPIC) was first company in Iran which started producing alkaline peroxide mechanical pulp (APMP) on a new Andritz 50000 tones/year at its mill in Maragheh city followed by establishment of another 50000 tones/year in Kermanshah city, Iran. Due to lack of required chemicals for the process including H2O2, Sodium Silicates, DTPA and Magnesium Sulfate and the subsequent high production costs mill trials were performed to examine the suitability of APMP process for producing packaging paperboards for which only alkaline addition is adequate. Different ranges of Alkali dosage were experimented and the resulted pulps were both evaluated online using FiberScan System supplied by Andritz and the laboratory tests. The results from this investigation demonstrated that APMP can be utilized as an alternative to produce standard quality packaging pulp and paper other than the printing purposes using less production costs.
