Izixhobo zokupakisha eziqhelekileyo zidlala indima ebalulekileyo kwishishini lezithambiso njengoko zingakhuseli kuphela iimveliso kodwa zikwanceda ekuphuculeni ukubukeka kwazo. Phakathi kwabo, i-AS (i-acrylonitrile styrene) kunye ne-PET (i-polyethylene terephthalate) isetyenziswa ngokubanzi ngenxa yeempawu zabo ezizodwa. I-AS yaziwa ngokungafihli nto kunye nokuqaqamba, ukodlula neglasi eqhelekileyo. Eli nqaku livumela umbono ocacileyo wesakhiwo sangaphakathi sepakethe, ukuphucula umgangatho obonakalayo jikelele.
I-AS inokumelana nobushushu obugqwesileyo, amandla okuthwala umthwalo, kunye nokumelana nokuguqulwa kunye nokuqhekeka.
I-PET, kwelinye icala, yamkelwa ngokuthamba kwayo, ukukhanya okuphezulu (ukuya kuthi ga kwi-95%), kunye nokuxinana okumangalisayo komoya, ukomelela, kunye nokunganyangeki kwamanzi. Nangona kunjalo, ayimelani nobushushu kwaye ihlala isetyenziswa njengezinto zokupakisha ukutya, iziselo kunye nezinto zokuthambisa.
Ukupakishwa kwezithambiso, ukukhethwa kwezinto eziphathekayo kubalulekile ekuqinisekiseni ukhuseleko kunye nesibheno semveliso. I-AS lukhetho oludumileyo lokupakishwa kwezithambiso ngenxa yokubonakala kwayo okuphezulu kunye nokuqaqamba.
Inika umbono ocacileyo wesakhiwo sangaphakathi semveliso, siphucula isibheno esibonakalayo kunye nokuvumela abathengi ukuba babone imveliso ngaphambi kokuthenga.
Ukumelana nobushushu be-AS kunye nokumelana nempembelelo ephezulu kuyenza ilungele ukukhusela izithambiso kwizinto zangaphandle, ukuqinisekisa umgangatho wazo kunye nokuthembeka.
Kwelinye icala, i-PET isetyenziswa kakhulu kwipakethe yezithambiso ngenxa yokubonakala kwayo okuphezulu kunye nokuqina komoya okugqwesileyo. Ukuthamba kwePET kuyayivumela ukuba iyilwe ngokuguquguquka ngaphakathiiintlobo ngeentlobo zeemilo zokupakisha zokuthambisa kunye nobukhulu.
Ukuchasana kwayo okuphezulu kwamanzi kuqinisekisa ukuba imveliso ikhuselwe kwimiphumo yomswakama, igcina umgangatho wayo kwixesha elide. Nangona kunjalo, kufuneka kuqatshelwe ukuba i-PET ayinakumelana nokushisa, ngoko isoloko isetyenziselwa ukupakishwa kwe-cosmetic okungafuneki ukuba ibonakale kumaqondo aphezulu.

Kushishino lwezithambiso olukhuphisana kakhulu, ukupakishwa kudlala indima ebalulekileyo ekutsaleni abathengi kunye nokuphembelela izigqibo zabo zokuthenga. Ukusetyenziswa kwe-AS kunye ne-PET kwi-cosmetic package ihlangabezana neemfuno zokubhenela okubonakalayo kunye nokukhuselwa kwemveliso.
Ukukhanya okuphezulu kwe-AS kunye nokuqaqamba kuyenza ilungele ukubonisa iimveliso, ngelixa i-PET's high water resistance and air-tightness iqinisekisa ukugcinwa komgangatho wemveliso.
Iimpawu ze-AS kunye ne-PET zibenza bafaneleke kwiintlobo ezahlukeneyo zokupakisha izimonyo.
Ngenxa yokukhanya okuphezulu kunye nokuqaqamba kwayo, i-AS ihlala isetyenziswa kwizikhongozeli zezithambiso ezicacileyo, ezivumela abathengi ukuba babone iimveliso ngaphakathi. Ukumelana nokushisa kwayo okugqwesileyo kunye nokuchasana kwempembelelo kwenza kube yinto efanelekileyo yokukhusela izimonyo ezahlukeneyo, ukuqinisekisa ukhuseleko lwabo ngexesha lokuthutha kunye nokugcinwa.
Kwelinye icala, ukucaca okuphezulu kwe-PET kunye nokuqina komoya kuyenza ilungele ukupakishwa kwezithambiso ezahlukeneyo, kubandakanya iibhotile kunye neejagi. Ukuthamba kwayo kuvumela ukuguquguquka koyilo, okuvumela ukudala ukupakishwa okukodwa kunye nokukhangayo kwizinto zokuthambisa.
Ukongeza kwisibheno sayo esibonakalayo, ukuchasana kweekhemikhali ze-AS kunye nokunyanzeliswa kwamanzi kwe-PET kuyenza ifaneleke ukugcina iintlobo ezahlukeneyo zokuthambisa.
Ukuxhatshazwa kweekhemikhali ze-AS kuqinisekisa ukuba ukupakishwa kuhlala kuhambelana xa udibana neefomyula zokuthambisa, ngelixa ukuxhatshazwa kwamanzi kwe-PET kukhusela imveliso kumswakama, ngaloo ndlela igcina umgangatho wayo kwixesha elide.
Ezi propati zenza i-AS kunye ne-PET aukhetho oluthembekileyo lokupakishwa kwezithambiso, ukuhlangabezana neemfuno zokusebenza kunye nobuhle boshishino.
Ukusetyenziswa kwe-AS kunye ne-PET kwi-cosmetic package ibonisa ukuzibophelela kweshishini ekuboneleleni abathengi ngekhwalithi ephezulu kunye nemveliso ebonakalayo ebonakalayo. Iimpawu eziphezulu zezi zixhobo zinceda ukuphucula amava onke okusebenzisa izimonyo, ukususela kumzuzu wokuthenga ukusetyenziswa kwemveliso. Ukungafihli kunye nokuqaqamba kwe-AS kwenza abathengi benze izigqibo ezinolwazi, ngelixa ukunganyangeki kwamanzi kwe-PET kunye nokuqina komoya kuqinisekisa umgangatho wemveliso.
Ukusetyenziswa kwe-AS kunye ne-PET kwizinto zokupakisha zokuthambisa kubonisa ukuzibophelela kweshishini ekuboneleleni abathengi ngeemveliso ezikhuselekileyo, ezintle nezikumgangatho ophezulu.
Iimpawu ezikhethekileyo ze-AS kunye ne-PET zibenza bafanelekele uluhlu olubanzi lokupakisha izimonyo, ukuhlangabezana neemfuno zeshishini lokusebenza kunye nobuhle. Njengoko ishishini lezithambiso liqhubeka nokuvela, ukusetyenziswa kwezinto ezintsha zokupakisha ezifana ne-AS kunye ne-PET kuya kudlala indima ebalulekileyo ekuhlangabezaneni nemfuno yabathengi yezithambiso ezinomtsalane nezithembekileyo.
