Tonse tikudziwa kuti kuuma kwapamwamba kwa zinthu za polypropylene kumawonjezeka ndi kuchuluka kwa zomwe zili, ndipo zimakhala ndi zotsatira zabwino zotsutsana ndi zowonongeka, kotero zimatha kugwiritsidwa ntchito nthawi zambiri, ndipo izi ndizo zabwino zomwe zimatha kubweretsa. Pofuna kupititsa patsogolo kukhazikika kwake komanso kusinthasintha, tidzawonjezera zinthu za polyethylene ku bolodi la polypropylene pp.
Pambuyo pa bolodi la PP logulitsidwa pamsika likuwonjezeredwa ndi polyethylene kupanga polima, ikhoza kusinthidwa mofulumira pakukana kutentha, kukana kwa dzimbiri, ndi mphamvu zamakina, kotero kuti mwachibadwa ikhoza kubweretsa chitsimikizo cha ntchito yabwino. Zoonadi, momwe mungasankhire bwino ndikofunika kwambiri, ndipo ubwino womwe ungabweretse pamapeto pake udzakhala wowonekera kwambiri, kotero chitetezo chopezedwa chidzakhala bwino.
Nthawi zambiri, kuuma kwapamtunda ndi kukana kwa pepala la PP ndizabwino, ndipo zotsatira zake zimakhala bwino mutawonjezera ulusi wagalasi. Mitundu yonse ya mapepala a polypropylene amagulu osiyanasiyana ali ndi makhalidwe ofanana, kotero angagwiritsidwe ntchito ngati imodzi mwa mapulasitiki abwino kwambiri a uinjiniya nthawi iliyonse, kupereka chitsimikizo chowonjezereka cha kupanga zipangizo zosiyanasiyana.
