Ibhokisi yokupakisha ukutya, njengoko igama lisitsho, isetyenziselwa ukupakisha iibhokisi zokutya, ingahlulwa ngokwezixhobo ezifana nezi: ibhokisi yomthi, ibhokisi yephepha, ibhokisi yelaphu, ibhokisi yesikhumba, ibhokisi yentsimbi, ibhokisi yokupakisha erhabaxa, njl., ingahlulwa ngokwegama lemveliso efana nezi: ibhokisi yesipho, ibhokisi yewayini, ibhokisi yetshokholethi, ibhokisi yepeni, ibhokisi yokupakisha ukutya, ibhokisi yokupakisha iti, njl. Ngoku iguqukele kwiibhokisi ezenziwe ngomthi, iphepha nezinye izinto ezixutywe kunye. Umsebenzi webhokisi yokupakisha: ukuqinisekisa ukhuseleko lokutya ekuthuthweni, ukuphucula umgangatho weemveliso, njl. Injongo yebhokisi yokupakisha ukutya kukukhusela ukutya kwimpembelelo yezinto zekhemikhali kunye neentsholongwane, ukuqinisekisa ukuba ukwakheka kwesondlo kunye nomgangatho wokutya awutshintshi, ukuze kukhuselwe impilo yabathengi. Ukongeza, ukutya okupakishiweyo kubonelela ngeemeko ezininzi ezilula zokuthutha, ukugcina, ukuthengisa nokusetyenziswa, ngelixa kukhuthaza ukuthengiswa. Ukupakisha ukutya okufanelekileyo kunokwandisa ubomi bokugcina kunye nobomi beshelufu, kwaye kunciphisa kakhulu ukuthambekela kokuwohloka kokutya. Izinto ezichaphazela umgangatho wokutya zezi: - ukukhanya; Okwesibini bubushushu; Okwesithathu yioksijini; Okwesine kukufuma; Okwesihlanu, iintsholongwane. Ukusuka kwimveliso yokutya, ukuthengiswa nokusetyenziswa kwembono ezintathu, injongo yebhokisi yokupakisha ukutya: – kukuthintela ukuwohloka, ukuqinisekisa umgangatho; Eyesibini kukuthintela ungcoliseko lweentsholongwane nothuli; Okwesithathu, ukulinganisela nokukhawulezisa imveliso yokutya; Okwesine, kuyanceda ekuthuthweni nasekujikelezeni kokutya; Okwesihlanu, ukunyusa ixabiso lempahla yokutya. Ibhokisi yokupakisha ukutya ngokwendlela equlathe ngayo izinto eziluhlaza, yahlulwe yaba yi-polyethylene, i-polypropylene, i-polyvinyl chloride nezinye iintlobo, i-polyethylene, i-polypropylene yiplastiki ekhuselekileyo, ingasetyenziselwa ukugcina ukutya. Iibhokisi zeplastiki ze-foam ezilahlwayo igama elipheleleyo yibhokisi yesidlo sangokuhlwa ye-polystyrene ene-foam enye, izinto eziluhlaza eziphambili yi-polystyrene kunye ne-agent ye-foam, i-polystyrene yi-polymers ye-styrene, ifika kuma-65 degrees Celsius, kuya kubakho imeko yasimahla ye-styrene kunye nokufuduka kohlobo lwezinto ezinobungozi ezibizwa ngokuba yi-dioxins, ukwenzakalisa umzimba womntu. Ukongeza, i-agent yokuvuthela ikwaluhlobo lwezixhobo zeekhemikhali eziyingozi emzimbeni womntu. Ezinye iibhokisi zokutya ezithathwayo eziphula imiqathango yesizwe yokutyiwa ziya kuvelisa ivumba elibi xa zizaliswe kukutya okushushu, okuzizinto ezinobuthi ezikhutshwa ziibhokisi zokutya zeplastiki ezifuthayo. Ezi zinto ziya kubangela umonakalo kwinkqubo yemithambo-luvo yomntu kwaye zisongele kakhulu impilo yabantu.
