Imfuno yeengxowa ze-polypropylene kunye neengxowa ezivela kushishino lwesamente ziye zanda kakhulu kule minyaka imbalwa idlulileyo.
ngenxa yokwanda kokufudukela kwabantu ezidolophini kunye nokukhula kwicandelo lemizi-mveliso.Iinkampani zamazwe ngamazwe zikhangele phambili
ukwanda kwemfuno evela kushishino lokwakha nolwakhiwo.Ukwanda okuthe chu kushishino lwesamente kuya kwanda
imfuno yokupakishwa kwayo, kwaye emva koko, iingxowa ezilukiweyo ze-polypropylene kunye neengxowa.Iingxowa ezilukiweyo zePolypropylene kunye neengxowa
ukunika amandla awona mandla kunye nokuphatha izinto ezilungileyo ngexesha lokuhamba kunye nokuhambisa.Zikhethwa kakhulu
yokupakishwa kwesamente.Kwiminyaka yakutshanje, kuye kwaphawulwa ukuba inani polypropylene elukiweyo
iingxowa kunye nabavelisi beengxowa zezicelo zemizi-mveliso zande kakhulu.

Ukukhula kwezoqoqosho, ukunyuka kwabemi, kunye nomvuzo olahlwayo wabantu emva koko zezona zinto ziqhubayo.
ukuze kwandiswe amathuba kumazwe asakhasayo.Ngenxa yeengxowa ezilukiweyo zepolypropylene kunye negalelo leengxowa ngaphakathi
izinto ezahlukeneyo zorhwebo ezinxulunyaniswa nobomi bemihla ngemihla bomntu kunokuqikelelwa ukuba imakethi yazo
Iingxowa ezilukiweyo ze-polypropylene kunye neengxowa kulindeleke ukuba zikhule kakhulu kwixesha loqikelelo.

Ngaphaya koko, ukuvalwa kwengxowa yeplastiki enefilim ebhityileyo kukhuthaza ngamandla imfuno kunye nokwamkelwa kweengxowa ezilukiweyo ezinepolypropylene kunye neengxowa.
Abadlali abaphambili bonyusa ukugxila kwabo ekwandiseni ukwenziwa kweengxowa ezilukiweyo ezinepolypropylene kunye neengxowa ukuze baphumelele.
njengabavelisi abathembekileyo belaphu eliphothiweyo.Nangona kunjalo, ukuthengiswa kweepolypropylene iingxowa ezilukiweyo kunye neengxowa kuwo wonke amashishini ezolimo
Kulindeleke ukuba kudlule intengiso kushishino lokwakha nolwakhiwo.Iingozi zokusingqongileyo ezinxulumene ne-PE (i-polyethylene)
iye yakhuthaza ukwamkelwa kweengxowa ezilukiweyo ezine-polypropylene kunye neengxowa njengenye indlela enokugcineka xa kuthelekiswa.

Nangona kunjalo, izinto ezinje ngendalo esingqongileyo, amandla kunye neendleko ziyaqhubeka ukwenza iingxowa ezilukiweyo zepolypropylene ezincinci kunye neengxowa
ukusuka kwiingxowa zayo ezilukiweyo ze-polypropylene ezingena-laminated kunye neengxowa.Inkqubo ekhoyo yolawulo malunga
ukwenziwa kunye nokusetyenziswa kweengxowa ezilukiweyo ezinepolypropylene kunye neengxowa kulindeleke ukuba zithintele ukukhula kwentengiso kwimimandla ephuhlileyo.
