Ukukhetha i-PCTG njengomsebenzi wokupakishwa kwezimonyo ngendlela oyifisayo kuhambisana nenkambiso yezikhathi futhi kuwukubonakaliswa komthwalo wemfanelo wenkampani emphakathini.

Ngakho-ke, kungabonakala ukuthi kunezizathu eziningi zokuthi kunganiibhodlela lokupakisha lezimonyoukwenza ngokwezifiso kukhetha i-PCTG njengento. Kusukela ekusebenzeni kwempahla kuya kuzici zokuvikela imvelo, ihambisana kakhulu nezidingo zezinkampani zezimonyo zokupakisha umkhiqizo kanye nokuphishekela kwabathengi imikhiqizo ehambisana nemvelo.

Ingacutshungulwa ngezindlela zendabuko zokubumba ezifana ne-extrusion, ukubunjwa komjovo, ukubunjwa kokushaywa nokubunjwa kwamabhamuza. Isetshenziswa kakhulu ebhodini naseshidini, ifilimu yokunciphisa ukusebenza okuphezulu, ibhodlela kanye nezimakethe zezinto ezimise okukhethekile; ingasetshenziselwa ukukhiqiza amathoyizi, izitsha zasendlini kanye nezinsiza zokwelapha, njll.; seludlule ezindinganisweni zokuxhumana zokudla ze-US FDA futhi lungasetshenziswa ekudleni, emithini naseimbiza yokupakisha yezimonyonezinye izinkambu.
