Xa kufikwa ekupakisheni, izinto ezisetyenzisiweyo zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokuthembeka kwemveliso. Esinye sezisombululo zokupakisha eziguquguqukayo nezisebenzayo yityhubhu ye-PE enamaleko amabini. Ezi tyhubhu zenziwe nge-polyethylene (PE), eyiplastiki esetyenziswa kakhulu eyaziwa ngokuqina kwayo kunye nokuguquguquka kwayo. Ukwakhiwa kwezi tyhubhu ezinamaleko amabini kunika amandla ongezelelweyo kunye neempawu zokuthintela, okwenza zifaneleke kwiintlobo ngeentlobo zezicelo kumashishini ahlukeneyo.
Iityhubhu ze-PE ezineeleya ezimbini zenzelwe ukubonelela ngokhuseleko kunye nokulula. Umaleko wangaphakathi wetyhubhu udla ngokwenziwa nge-polyethylene exineneyo (LDPE), eyaziwa ngokuguquguquka kwayo kunye nokumelana nokufuma. Lo maleko wangaphakathi usebenza njengesithintelo, uthintela umxholo ukuba ungavuzi okanye ungcoliswe zizinto zangaphandle. Kwelinye icala, umaleko wangaphandle wenziwe nge-polyethylene exineneyo (HDPE), eyongeza amandla kunye nokuqina kwityhubhu. Olu lwakhiwo lweeleya ezimbini lubonelela ngomaleko owongezelelweyo wokhuseleko, okwenza ezi tyhubhu zilungele ukupakisha iimveliso ezahlukeneyo, kubandakanya amayeza, iimveliso zokhathalelo lomntu, izinto zokutya, kunye neekhemikhali zoshishino.
Enye yezona ngenelo ziphambili zokusebenzisa iityhubhu ze-PE ezineeleya ezimbini kukuguquguquka kwazo. Ezi tyhubhu ziza ngobukhulu obahlukeneyo kunye neemilo, nto leyo ezenza zifaneleke kwiintlobo ezahlukeneyo zeemveliso. Nokuba yikhrimu, iloshini, ijeli, ioyile, okanye nayiphi na enye into ethambileyo, iityhubhu ze-PE ezineeleya ezimbini zibonelela ngesisombululo sokupakisha esilula nesithembekileyo. Ukuguquguquka kweleya yangaphakathi ye-LDPE kuvumela ukusasazwa kwemveliso ngokulula, ngelixa ileya yangaphandle ye-HDPE iqinisekisa ukuba ityhubhu ihlala iqinile ngexesha lokuphathwa nokuthuthwa.
Ukongeza ekuguquguqukeni nasekuqineni kwazo, iityhubhu ze-PE ezineengqimba ezimbini zikwabonelela ngokuprintwa okugqwesileyo. Oku kuthetha ukuba abavelisi banokuzihlengahlengisa ngokulula iityhubhu ngophawu, ulwazi lwemveliso, kunye nemiyalelo yokusetyenziswa, nto leyo ephucula ukuthandeka kunye nokusebenza kwephakheji. Ngaphezu koko, ezi tyhubhu zilula kwaye zingabizi kakhulu, nto leyo eyenza ukuba zibe lukhetho olungabizi kakhulu kubavelisi nakubathengi.
Ngokwembono yozinzo, iityhubhu ze-PE ezineeleya ezimbini nazo ziyindlela efanelekileyo yokupakisha. I-Polyethylene yinto enokusetyenziswa kwakhona, kwaye abavelisi abaninzi basebenzisa ngakumbi i-PE ephinda isetyenziswe ukuvelisa ezi tyhubhu, ukunciphisa impembelelo yokusingqongileyo kunye nokukhuthaza uqoqosho olujikelezayo.
Ukuqukumbela, iityhubhu ze-PE ezineeleya ezimbini zibonelela ngesisombululo sokupakisha esomeleleyo nesiguquguqukayo kwiimveliso ezahlukeneyo. Ukwakhiwa kwazo ezineeleya ezimbini kubonelela ngokulinganisela kokuguquguquka, amandla, kunye neempawu zokuthintela, okwenza zibe lukhetho oluthembekileyo kubavelisi kunye nabathengi ngokufanayo. Ngenxa yokukwazi ukwenza ngokwezifiso, ukukhusela, kunye nokuhambisa iimveliso ngokulula, ezi tyhubhu ziyaqhubeka nokuba lukhetho oludumileyo kushishino lokupakisha. Nokuba ukwishishini lamayeza, lokhathalelo lomntu, okanye lokutya, iityhubhu ze-PE ezineeleya ezimbini zifanelekile ukuqwalaselwa kwiimfuno zakho zokupakisha.
