Iipolypropylene (PP) iingxowa ezilukiweyo, njengento ebalulekileyo yokupakisha, isetyenziswe ngokubanzi kwimarike kwiminyaka yakutshanje, ngakumbi ekuthuthweni nasekugcinweni kwezinto ezininzi. Imbali yeengxowa ezilukiweyo zePP zinokulandelwa kwiminyaka yee-1950, xa ukuveliswa kwezixhobo zepolypropylene kubeka isiseko sokuveliswa kweengxowa ezilukiweyo. Ngokuqhubela phambili okuqhubekayo kwetekhnoloji, inkqubo yokuveliswa kweengxowa ezilukiweyo zePP ziye zakhula ngokuthe ngcembe, zenza iintlobo ezahlukeneyo zeengxowa ezilukiweyo esizaziyo namhlanje.
Kwiintsuku zokuqala, iingxowa ezilukiweyo zePP zazisetyenziswa ikakhulu kwezolimo kunye namashishini okwakha. Njengoko imfuno yemarike yanda, abavelisi baqala ukuphuhlisa iimveliso ezinomthamo omkhulu, ezizezi iingxowa ezininzi. Iingxowa ezininzi zidla ngokusetyenziselwa ukuthutha nokugcina izinto ezininzi, njengezichumisi, iinkozo, kunye neeminerali. Baneenzuzo zomthamo oqinileyo wokuthwala umthwalo, ukuxhathisa ukunxiba, kunye nokumelana nokukrazula. Ukuvela kwabo kuye kwaphucula kakhulu ukusebenza kakuhle kwamalungiselelo kunye nokunciphisa iindleko zokuhamba.
Ukungena kwinkulungwane yama-21, umda wokusetyenziswa kweengxowa ezilukiweyo zePP ziye zandiswa ngokuqhubekayo. Ukongeza kwimizi-mveliso yemveli yezolimo kunye neyokwakha, iingxowa ezilukiweyo zePP nazo sele ziqalisile ukusetyenziswa ngokubanzi ekutyeni, kwiikhemikhali, kumayeza nakwamanye amasimi. Ngokunyuka kolwazi lokhuseleko lokusingqongileyo, abavelisi abaninzi sele beqalisile ukuphonononga izinto ezinokonakala kwaye baphinda basebenzise iingxowa ezilukiweyo zePP ukuhlangabezana nemfuno yentengiso yeemveliso ezihambelana nokusingqongileyo.
Ngokubanzi, imbali yophuhliso lweengxowa ezilukiweyo zePP kunye neengxowa ezininzi zibonisa inkqubela yesayensi yezinto kunye nobugcisa bokuvelisa. Kwixesha elizayo, ngophuhliso oluqhubekayo lwesayensi kunye nethekhinoloji, imisebenzi kunye neendawo zokusetyenziswa kweengxowa ezilukiweyo zePP ziya kuhlukahluka kwaye zibe yinxalenye eyimfuneko kushishino lokupakisha lwangoku.
