Embonisweni yokupakisha ukudla, ukukhetha impahla efanele yesitsha sokudla esilahlwayo kubalulekile ukuqinisekisa ukuphepha kokudla, ukuba lula, kanye nesibopho semvelo. Lo mhlahlandlela uhlinzeka ngokubuka okujulile ezintweni ezivamile ezisetshenziselwa izitsha zokudla ezilahlwayo, izindinganiso zokudla, nokufaneleka kwazo ezinhlelweni zokudla okuthathwayo. Noma ngabe ungumnikazi webhizinisi lokudla noma uchwepheshe wezokupakisha, ukuqonda lezi zici kuzokusiza ukuthi wenze izinqumo ezinolwazi. I-Guangdong Teguan Industrial Co., Ltd., umholi kwezixazululo zokupakisha ezihambisana nemvelo, ihlinzeka ngezitsha eziningi zokudla eziklanyelwe ukuhlangabezana nezidingo zesevisi yokudla yesimanje ngenkathi iphambili ukusimama.

Izitsha zokudla ezingasetshenziswa kanye nokuphonswa ngemva kokusebenzisa zibalulekile embonini yokudla esheshayo yanamuhla, ikakhulukazi ezinsizakalweni zokudla okuthathwayo nokulethwayo. Lezi zitsha akumele zigcine nje ikhwalithi nokusha kokudla kodwa futhi kumele zihambisane nemithetho eqinile yezempilo nokuphepha. Kunezinhlobonhlobo zezinto ezitholakalayo, ngayinye enezici ezihlukile ezithinta ukuqina, ukumelana nokushisa, nomthelela emvelweni. Lesi sigaba sethula izinto eziyinhloko ezisetshenziswa kakhulu, sibeka isisekelo sokuqonda izinzuzo zazo eziyinhloko nemikhawulo yazo.

Ukukhethwa kwezinto ezisetshenzisiweyo kuthinta ngqo ulwazi lomthengi nokusebenza kahle. Ngokwesibonelo, iziqukathi ezenziwe nge-polypropylene (PP) zinokumelana nokushisa okufanele ukufakwa ku-microwave, kanti i-polyethylene terephthalate (PET) inikeza ukucaca okuhle kakhulu futhi ivame ukusetshenziselwa ukupakisha ukudla okubandayo. Iziqukathi ze-polystyrene (PS) azisindi kodwa zingaba nokubekezelelana okulinganiselwe kokushisa. Ngezinkinga zemvelo ezikhulayo, izinketho ezibola ngokwemvelo njenge-polylactic acid (PLA) zithola ukunakwa njengezindlela ezingenzeka. Ukuqonda lezi zinto kusiza amabhizinisi ukuthi akhethe ukupakisha okuhambisana nemodeli yabo yesevisi kanye nokulindela kwamakhasimende.

I-Polypropylene (PP) ingenye yezinto ezithandwa kakhulu ezisetshenziselwa izitsha zokudla ezingasetshenziswa futhi, ngenxa yokumelana kwayo nokushisa okuphezulu nokuzinza kwamakhemikhali. Ifanele ukudla okushisayo futhi ingasetshenziswa eziko le-microwave ngaphandle kokushintsha kwayo. Izitsha ze-PP ziqinile, zilula, futhi zingasetshenziswa kabusha, okwenza zibe yisinqumo esihle ezindaweni eziningi zokudla.

I-Polyethylene terephthalate (PET) isetshenziswa kabanzi kokuphuza abandayo nokudla okubandisiwe. Ukucaca kwayo okuhle kuvumela amakhasimende ukuthi abone okuqukethwe ngokucacile, okwengeza ukukhanga komkhiqizo. Kodwa-ke, i-PET inokubekezelelana nokushisa okuphansi uma iqhathaniswa ne-PP, okukhawulela ukusetshenziswa kwayo ezintweni zokudla ezishisayo. Izitsha ze-PET zingasetshenziswa kabusha futhi zinikeza izakhiwo ezinhle zokuvikela ikhwalithi yokudla.

Izitsha ze-Polystyrene (PS) azisindi futhi azibizi, zivame ukusetshenziswa ukupakisha ukudla okusheshayo. Ngenkathi i-PS inikeza ukufakwa kahle kokudla okushisayo, ayimelani nokushisa njenge-PP futhi ngokuvamile ayikwazi ukufakwa ku-microwave. Ngaphezu kwalokho, izinkinga zemvelo nge-PS ziye zaphetha izinkampani eziningi ukuthi zifune izinto ezihlukile.

Ukukhetha impahla yokugcina ukudla okungasetshenziswanga kuncike kakhulu ohlotsheni lokudla nendlela yokuhlinzeka. Ukuze kuthathwe ngaphandle nokulethwa, iziqukathi kumele zigcine ubuqotho bokudla ngesikhathi sokuhamba futhi zibe lula ukuyisebenzisa kubathengi. Iziqukathi ze-PP zikhangisa kulokhu ngenxa yokumelana kwazo nokushisa kanye namandla akhiwo, okwenza zifaneleka ukudleni okushisayo njengezobho nezokupheka.

Izikhwama ze-PET zikhangiswa kakhulu ezidleni ezibandayo, emakhukhwini, naseziphuzweni, zinikeza ukubukeka okuhehayo ngokubukeka kwazo okucacile. Izikhwama ze-PS, nakuba zivamile, ziya zishintshwa kakhulu ngenxa yokukhathazeka kwemvelo kanye nezithiyo zokusebenza ngaphansi kokushisa. Amabhizinisi okudla kumele abheke ibhajethi, ukusebenza, kanye nomthelela wemvelo lapho ekhetha izinto zokupakisha ezifanele izinsizakalo zawo zokuthatha.

Izitsha ezingadilizwa yizinto eziphilayo, njengezo zenziwe nge-PLA (polylactic acid), sezidumile kakhulu njengezindlela ezihambisana nemvelo esikhundleni samaplastiki ajwayelekile. Lezi zitsha, ezitholakala emithonjeni evuselelekayo njengobhontshisi wommbila, zihlose ukunciphisa ukungcola kwamaplastiki nokunciphisa ukuncika emafutheni ezilwane. Noma kunjalo, izinzuzo zazo zemvelo zidinga ukucatshangelwa ngokucophelela.

Iziqukathi ze-PLA zingakwazi ukubola ngaphansi kwezimo zezimboni kodwa zingase zingaboli kahle ezindaweni ezivamile zokulahla udoti. Ngaphezu kwalokho, zinokumelana nokushisa okuphansi uma kuqhathaniswa ne-PP, okukhawulela ukusetshenziswa kwazo nokudla okushisayo. I-Guangdong Teguan Industrial Co., Ltd. yenza iziqukathi zokupakisha ukudla ezibola ngokwemvelo ezihlangabezana namazinga aqinile ekhwalithi nemvelo, enikeza imikhiqizo ehambisana nemvelo nokusebenziseka kalula. Amabhizinisi kufanele ahlolisise umjikelezo ogcwele kanye nengqalasizinda yokulahla ngaphambi kokushintshela eziqukathi ezibola ngokwemvelo.

Ukuqinisekisa ukuthi izitsha zokudla ezingadilizwa zihambisana namazinga okudla kubalulekile ukuphepha kwabathengi nokuthobela imithetho. I-FDA (Food and Drug Administration) e-United States kanye ne-LFGB (Lebensmittel- und Futtermittelgesetzbuch) eJalimane yizindinganiso ezimbili eziphathwayo ezilawula izinto ezithinta ukudla.

Ukuqinisekiswa kwe-FDA kuqinisekisa ukuthi impahla iphephile ukuthintana ngqo nokudla futhi ayinazo izinto eziyingozi. Ukuqinisekiswa kwe-LFGB, okubhekwa njengokuqine kakhulu, kuhlole ukuthuthelana kwamakhemikhali okungenzeka nokuphepha okuphelele. I-Guangdong Teguan Industrial Co., Ltd. yenza iziqukathi ezihambisana namazinga e-FDA kanye ne-LFGB, zinikeza amaklayenti ukuzethemba ekuphepheni komkhiqizo nokwamukelwa emakethe yamazwe ngamazwe. Ukuqonda lezi ziqinisekiso kusiza amabhizinisi ukuthi akhethe iziqukathi ezihlangabezana nezidingo zomthetho nezokuphepha ezifundeni ezahlukene.

Ukuphepha kwe-microwave kubalulekile ezitsheni zokudla ezingasetshenziswa futhi zilahlwe, ikakhulukazi ekudleni okulethwa kanye nokudla okuklanyelwe ukudliwa ngokushesha. Akuwona wonke amaplastiki afanele ukusetshenziswa ku-microwave; izinto ezingafanele zingancibilika, zigoqeke, noma zikhiphe amakhemikhali ayingozi lapho zishiswa.

Izitsha ze-Polypropylene (PP) ngokuvamile zingasetshenziswa ku-microwave futhi zigcina ukuma kwazo nokuzinza ezingeni lokushisa eliphezulu. Ngokuphambene, izitsha ze-PET ne-PS ngokuvamile azifanele ukusetshenziswa ku-microwave ngenxa yokubekezelelana kwazo okuphansi nokushisa. Izitsha ezibola ngokwemvelo njenge-PLA nazo zinokumelana okulinganiselwe ku-microwave futhi zingase zishintshe umumo noma zidedele izinto. Kubalulekile ukuhlola imininingwane yesitsha nezitifiketi zokuphepha kwe-microwave. I-Guangdong Teguan Industrial Co., Ltd. inikeza isiqondiso esicacile mayelana nokuhambisana kwemikhiqizo yayo ne-microwave, iqinisekisa ukusetshenziswa okuphephile kwabathengi.

Ukukhetha impahla efanele yesitsha sokudla esilahlayo kuhilela ukulinganisa ukuphepha kokudla, ulwazi lomthengi, umthelela emvelweni, kanye nokuthobela imithetho. Izinto ezifana ne-PP, i-PET, ne-PS zineqhaza elihlukile ekupakisheni ukudla, kanti izinketho ezingaboli zinikeza izinzuzo ezithembisayo kodwa eziyinkimbinkimbi. Ukuqonda izindinganiso ze-FDA ne-LFGB zokudla kuqinisekisa ukuphepha kanye nesiqinisekiso sekhwalithi. Ukuphepha kwe-microwave kuyinto ebalulekile enye yokudla okunethezekile.

I-Guangdong Teguan Industrial Co., Ltd. igqama njengomlingani onokwethenjelwa enikeza uhla oluphelele lweziqukathi zokudla ezakhiwe ngezinto ezahlukahlukene ukuze kuhlangatshezwane nezidingo ezahlukahlukene. Ngeminyaka engaphezu kwamashumi amabili yokuhlangenwe nakho nokuzibophezela ekusimameni, banikeza izixazululo zokupakisha ezintsha, eziqinisekisiwe, nezingekho emvelweni ezenzelwe imboni yokudla. Ukuhlola okunikezwa kwemikhiqizo yabo nokufunda kabanzi ngezixazululo zabo zokupakisha ezisimeme, vakashela i-Ikhaya ikhasi bese upheqa izinketho ezinemininingwane ku-Imikhiqizo ikhasi. Ngomlando wenkampani kanye nemizamo yokusimama, hlola i-Mayelana Nathi isigaba.
