Isidingo sezikhwama ze-polypropylene namasaka embonini kasimende senyuke kakhulu eminyakeni embalwa edlule,
ngenxa yokwanda kokukhula kwamadolobha kanye nokukhula emkhakheni wezimboni. Izinkampani zamazwe ngamazwe zibheke ngabomvu
ukwanda kwesidingo esivela embonini yezokwakha nokwakha. Ukunyuka okuqhubekayo embonini kasimende kuzokhula
isidingo sokupakishwa kwayo, bese kuba nezikhwama namasaka ezenziwe nge-polypropylene. Izikhwama ze-polypropylene namasaka
ukunikeza amandla aphezulu kanye nokuphatha izinto ezibonakalayo ngesikhathi sokuthutha nokuthunyelwa. Zithandwa kakhulu
okokufaka usimende. Eminyakeni yamuva, kuye kwaphawulwa ukuthi inani polypropylene nokwelukiweyo
abakhiqizi bezikhwama namasaka bezicelo zezimboni bakhule kakhulu.

Ukukhula komnotho, ukwanda kwenani labantu, kanye neholo labantu elilahlwayo okulandelayo yizona zinto ezihamba phambili.
amathuba engeziwe emazweni asathuthuka. Ngenxa yezikhwama ezilukiwe ze-polypropylene kanye nomnikelo wamasaka
impahla ehlukahlukene ehlotshaniswa nokuphila kwansuku zonke komuntu kungalindelwe leyo makethe
Izikhwama ezilukiwe ze-polypropylene namasaka kulindeleke ukuthi zikhule kakhulu esikhathini sokubikezela.

Ngaphezu kwalokho, ukuvinjelwa kwesikhwama sepulasitiki esinefilimu elincanyana kukhulisa kakhulu isidingo nokwamukelwa kwezikhwama namasaka okwelukwe nge-polypropylene.
Abadlali abamqoka bakhulisa ukugxila kwabo ekwandiseni ukwenziwa kwezikhwama namasaka enziwe nge-polypropylene ukuze baphumelele.
njengabakhiqizi abanokwethenjelwa bendwangu eyenziwe ngokwezifiso. Kodwa-ke, ukuthengiswa kwezikhwama ezilukiwe ze-polypropylene namasaka kuzo zonke izimboni zezolimo
kulindeleke ukuthi kusibekele ukuthengiswa embonini yezokwakha nokwakha. Izingozi zemvelo ezihlobene ne-PE (i-polyethylene)
igqugquzele ukwamukelwa kwezikhwama namasaka enziwe nge-polypropylene njengenye indlela esimeme ngokuqhathaniswa.

Kodwa-ke, izinto ezifana nemvelo, amandla kanye nezindleko ziyaqhubeka nokwenza izikhwama ezilukiwe ze-polypropylene ezincane namasaka
kusukela ezikhwameni zayo ezilukiwe ze-polypropylene ezingezona elayiniwe kanye namasaka. Uhlaka lokulawula olukhona mayelana
ukukhiqizwa nokusetshenziswa kwezikhwama ezilukiwe ze-polypropylene namasaka kulindeleke ukuthi kuvimbe ukukhula kwemakethe ezifundeni ezithuthukile.
