Uma kukhulunywa ngokupakisha, izinto ezisetshenziswayo zidlala indima ebalulekile ekuqinisekiseni ukuphepha nobuqotho bomkhiqizo. Esinye sezixazululo zokupakisha eziguquguqukayo nezisebenzayo yishubhu le-PE elinezingqimba ezimbili. Lawa mashubhu enziwe nge-polyethylene (PE), okuyipulasitiki esetshenziswa kabanzi eyaziwa ngokuqina kwayo nokuguquguquka kwayo. Ukwakhiwa kwala mashubhu anezingqimba ezimbili kunikeza amandla engeziwe kanye nezakhiwo zokuvimbela, okwenza afaneleke kakhulu ezinhlotsheni eziningi zezicelo kuzo zonke izimboni ezahlukene.
Amashubhu e-PE anezingqimba ezimbili aklanyelwe ukuhlinzeka kokubili ukuvikelwa kanye nokulula. Ingqimba yangaphakathi yeshubhu ngokuvamile yenziwe nge-polyethylene ephansi (LDPE), eyaziwa ngokuguquguquka kwayo kanye nokumelana nomswakama. Le ngqimba yangaphakathi isebenza njengesivikelo, ivimbela okuqukethwe ukuthi kungavuzi noma kungangcoliswa yizinto zangaphandle. Ingqimba yangaphandle, ngakolunye uhlangothi, yenziwe nge-polyethylene ephezulu (HDPE), enezela amandla nokuqina kweshubhu. Lokhu kwakhiwa kwezingqimba ezimbili kunikeza ungqimba olwengeziwe lokuvikela, okwenza la mashubhu afaneleke kakhulu ekupakisheni imikhiqizo eyahlukahlukene, kufaka phakathi imithi, imikhiqizo yokunakekela umuntu siqu, izinto zokudla, kanye namakhemikhali ezimboni.
Enye yezinzuzo eziyinhloko zokusebenzisa amashubhu e-PE anezingqimba ezimbili ukuguquguquka kwawo. Lawa mashubhu eza ngobukhulu obuhlukahlukene kanye nezimo, okwenza afaneleke ezinhlotsheni ezahlukene zemikhiqizo. Kungakhathaliseki ukuthi ukhilimu, i-lotion, ijeli, i-ointment, noma yimuphi omunye umuthi oqinile, amashubhu e-PE anezingqimba ezimbili anikeza ikhambi lokupakisha elilula nelithembekile. Ukuguquguquka kwengqimba yangaphakathi ye-LDPE kuvumela ukusabalalisa umkhiqizo kalula, kuyilapho ungqimba lwangaphandle lwe-HDPE luqinisekisa ukuthi ishubhu lihlala liphelele ngesikhathi sokuphathwa nokuthuthwa.
Ngaphezu kokuguquguquka kwawo namandla awo, amashubhu e-PE anezingqimba ezimbili nawo anikeza ukuphrinta okuhle kakhulu. Lokhu kusho ukuthi abakhiqizi bangenza ngokwezifiso amashubhu kalula ngophawu, ulwazi lomkhiqizo, kanye nemiyalelo yokusebenzisa, okuthuthukisa ukukhanga okuphelele kanye nokusebenza kwephakheji. Ngaphezu kwalokho, la mashubhu alula futhi ayabiza, okwenza abe ukukhetha okungabizi kokubili kubakhiqizi nakubathengi.
Ngokombono wokuzinza, amashubhu e-PE anezingqimba ezimbili nawo ayindlela enhle yokupakisha. I-Polyethylene iyinto engasetshenziswa kabusha, futhi abakhiqizi abaningi basebenzisa kakhulu i-PE esetshenziswa kabusha ukukhiqiza la mashubhu, benciphisa umthelela emvelweni futhi bekhuthaza umnotho ojikelezayo.
Ekuphetheni, amashubhu e-PE anezingqimba ezimbili anikeza isisombululo sokupakisha esiqinile nesiguquguqukayo semikhiqizo ehlukahlukene. Ukwakhiwa kwawo okunezingqimba ezimbili kunikeza ibhalansi yokuguquguquka, amandla, kanye nezakhiwo zokuvimbela, okwenza kube ukukhetha okuthembekile kwabakhiqizi kanye nabathengi ngokufanayo. Njengoba benekhono lokwenza ngokwezifiso, ukuvikela, nokusabalalisa imikhiqizo kalula, la mashubhu ayaqhubeka nokuba ukukhetha okuthandwayo embonini yokupakisha. Kungakhathaliseki ukuthi usembonini yezokwelapha, yokunakekelwa komuntu siqu, noma yokudla, amashubhu e-PE anezingqimba ezimbili afanele ukucatshangelwa ngezidingo zakho zokupakisha.
