Iplastiki yePolyethylene (PE), into esetyenziswa ngokuqhelekileyo ukupakishwa kokutya, iye yafumana ingqwalasela ngenxa yobuninzi bayo kunye nokhuseleko. Iplastiki ye-PE i-polymer eyenziwe ngamacandelo e-ethylene, eyaziwayo ngokuzinza kwayo kunye nokungabuyi-reactivity. Ezi zakhiwo zenza ukuba i-PE ibe yinto efanelekileyo kwizicelo zebakala lokutya, njengoko ingangeni kwiikhemikhali ezinobungozi ekutyeni, nangona ibonakaliswe kumaqondo okushisa ahlukeneyo.
Izifundo zoKhuseleko kunye neMimiselo
Uphando olubanzi kunye nemimiselo engqongqo iqinisekisa ukuba iplastiki ye-PE yebakala lokutya ikhuselekile kuqhagamshelwano lokutya. Uphononongo lubonise ukuba iplastiki ye-PE ayikhuphi izinto ezinobungozi phantsi kweemeko eziqhelekileyo zokusetyenziswa. Imibutho elawulayo efana ne-US Food and Drug Administration (FDA) kunye ne-European Food Safety Authority (EFSA) iseke izikhokelo kunye nemigangatho ekufuneka i-PE plastiki ihlangabezane nayo ukuze ihlelwe njengebakala lokutya. Le migangatho ibandakanya ukuvavanywa kokufuduka kweekhemikhali, ukuqinisekisa ukuba naluphi na ukuhanjiswa kwezinto ukusuka kwiplastiki ukuya kukutya kuhlala kwimida ekhuselekileyo.
Izicelo eziqhelekileyo kwiPackaging yokutya
Iplastiki ye-PE isetyenziswa ngokubanzi kwiifom ezahlukeneyo zokupakisha ukutya, kubandakanywaIingxowa ze-PE, iingxowa uziphu, kwayeiingxowa ziplock. Ezi zisombululo zokupakishwa zibonelela ngokumelana nokufuma okugqwesileyo, ukuguquguquka, kunye nokuqina, zibenza zilungele ukugcina uluhlu olubanzi lweemveliso zokutya. Iingxowa ze-PE, umzekelo, zihlala zisetyenziselwa imveliso entsha, i-snacks, kunye nokutya okufriziwe ngenxa yokukwazi ukugcina ubutsha kunye nokwandisa ubomi beshelufu.
Ukuthelekisa nezinye iiPlastiki
Xa kuthelekiswa nezinye iiplastiki, ezifana ne-polyvinyl chloride (PVC) kunye ne-polystyrene (PS), iplastiki ye-PE ithathwa njengekhuselekile kwaye ihambelana nokusingqongileyo. I-PVC, umzekelo, inokukhupha iikhemikhali ezinobungozi njenge-phthalates kunye ne-dioxins, ngakumbi xa ishushu. Ngokwahlukileyo, ubume bemichiza yeplastiki ye-PE elula kunye nokuzinza kuyenza ibe lukhetho olukhethiweyo lokupakishwa kokutya, njengoko ibeka umngcipheko omncinci wosulelo.
INkxaso yeDatha kunye noPhando
Idatha evela kwizifundo zeshishini ixhasa ukhuseleko lweplastiki ye-PE. Umzekelo, uphononongo oluqhutywe yi-EFSA lufumanise ukuba ukufuduka kwezinto ukusuka kwiplastiki ye-PE ukuya kukutya kwakuphakathi kwemida yokhuseleko emiselweyo. Ukongeza, ukuphinda kusetyenziswe kwakhona okuphezulu kweplastiki ye-PE kwandisa isibheno sayo, njengoko inokucutshungulwa ngokufanelekileyo kwiimveliso ezintsha, ukunciphisa impembelelo yokusingqongileyo.
Ukuququmbela,Iingxowa ze-PE, iingxowa uziphu, kwayeiingxowa ziplockezenziwe ngeplastiki ye-PE yebakala lokutya zikhuselekile kwaye zilukhetho oluthembekileyo lokupakishwa kokutya. Ukuzinza kwabo kweekhemikhali, ukuthotyelwa kwemigangatho yokhuseleko, kunye nokusetyenziswa ngokubanzi kwishishini kubenza babe lolona khetho lubalaseleyo kubathengi abafuna ukugcina nokukhusela ukutya kwabo. Ukufumana ulwazi oluthe kratya malunga neplastiki ye-PE kunye nokusetyenziswa kwayo, nceda ujonge izibonelelo ezinikiweyo.
