Emkhakheni wezokudla osheshayo wanamuhla, ukukhetha impahla efanele yokugcina ukudla engasetshenziswanga kabusha kubalulekile kumabhizinisi afuna ukuhlinzeka ngezixazululo zokupakisha eziphephile, ezilula, nezihlakaniphile. Abathengi baphinde baphakamise izidingo zokuthi kube nezikhwama zokudla ezihambisana nezinga lokudla, ezingagcina ikhwalithi nokuphepha kokudla kwabo kodwa futhi zihambisane nezinkathazo ezikhulayo zemvelo. Le mhlahlandlela ephelele ihlola izinto ezivamile ezisetshenziswa ezikhwameni zokudla ezingasetshenziswanga kabusha, izinzuzo nezinkinga zazo, izindinganiso zokuphepha okufanele zifezekiswe, nokuthi abakhiqizi abathembekile njengeGuangdong Teguan Industrial Co., Ltd. bahola kanjani imboni ekunikezeni imikhiqizo yokupakisha yokudla engcono.

Izitsha zokudla ezilahlwayo zenziwa ngezinto ezahlukahlukene, ngayinye ihambisana nezidingo ezithile zenkonzo yokudla. Izinto ezisetshenziswa kakhulu zihlanganisa iPolypropylene (PP), iPolyethylene Terephthalate (PET), iPolystyrene (PS), kanye nePolylactic Acid (PLA). Ukuqonda izici, izicelo, nemikhawulo yalezi zinto kusiza amabhizinisi ukuthi akhethe ukupakisha okuhle kakhulu okulinganisa ukuphepha kokudla, ukuqina, nomthelela kwemvelo.

I-Polypropylene ithandwa kakhulu ngenxa yokumelana kwayo kahle nokushisa, okuyenza ilungele ukupakisha ukudla okushisayo nokudla okungafakwa ku-microwave. Indawo yayo yokuqina ephakeme iqinisekisa ukuthi izitsha zigcina isimo sazo nokuba khona kwazo lapho kushisa, kuyilapho futhi zingakwazi ukugaywa kabusha. Izitsha ze-PP ezisezingeni lokudla zibonakala kabanzi ngokuqina kwazo nokuphepha lapho zithintana nezinhlobo ezahlukahlukene zokudla, zinikeza lula ezinsizakalweni zokuthatha nokulethwa.

I-PET isetshenziswa kakhulu ekupakisheni ukudla okubandayo ngenxa yokucaca kwayo, okuvumela abathengi ukuthi babone ukudla ngaphakathi kalula. Ayisindi kodwa inamandla, okwenza ibe yinhle kakhulu kumasaladi, amadizethi, neziphuzo. Iziqukathi ze-PET nazo ziyakwazi ukugaywa kabusha, okufaka isandla ezinkethweni zokulahlwa ezizinzile lapho ziphethwe kahle. Kodwa-ke, azifaneleki kangako ezicelo zokudla okushisayo ngenxa yokubekezelelana okulinganiselwe kokushisa.

I-Polystyrene, ikakhulukazi ngendlela ye-foam, iyinto elula futhi enezinhlaka ezivimbela ukushisa evame ukusetshenziswa ezitsheni zokuthatha. Nakuba inikeza ukuqina okuhle nokuvikelwa kokushisa, ibangele ukukhathazeka mayelana nokuphuma kwemichiza, ikakhulukazi uma ibonakaliswa ekushiseni. Abaningi abahlinzeki bokudla bayahamba kude ne-PS ngenxa yalezi zinkinga zokuphepha nezemvelo, bekhetha ezinye izinketho eziphephile.

I-PLA iyinto engabola, engahlanganiswa ethathwa emithonjeni ephindwayo efana ne-starch ye-corn noma ushukela. Ibonisa inketho enobungane bemvelo yezitsheni zokudla ezithathelwayo, ikhangela amabhizinisi nabathengi abakhathalela ukuvikelwa kwemvelo. Nokho, i-PLA inokuqina okulinganiselwe kokushisa futhi ivamise ukuba ingafaneleki ekupakisheni ukudla okushisayo noma ekusetshenzisweni kwe-microwave. Ukuze ibole, kudinga izikhungo zokuhlanganisa ezimbonini, ezingahluka ngokwendawo.

Izikhwama zokudla ezisetshenziswayo zinikeza ukuhamba okungafani, ikakhulukazi emakethe yokuthatha nokulethwa. Zisiza ukugcina ukuphepha kokudla nokusha ngesikhathi sokuhamba, kuqinisekisa ukwaneliseka kwamakhasimende. Ngaphezu kwalokho, lezi zikhwama zisebenza kahle kwezomnotho kumabhizinisi ngokunciphisa isidingo sokuhlanza nokuphatha izinto ezisetshenziswayo.

Uhlanga lwezinto ezisetshenziswayo lwezikhwama luvumela amabhizinisi ukukhetha ukupakisha okufanele kwezinhlobo zokudla ezithile — kusukela ezidleni ezishisayo ezidinga izikhwama eziphikisana nokushisa njenge-PP kuya ezidleni ezibandayo ezipakishwe ezikhwameni ezicacile ze-PET. Kubalulekile, ukusetshenziswa kwezikhwama ezivunyelwe zokudla kuqinisekisa ukuhlanzeka nokuphepha, kuhambisana nezindinganiso zokulawula ezivikela impilo yomthengi.

Naphezu kwezinzuzo zazo, iziqukathi zokudla ezisetshenziswayo zikhuphula ukukhathazeka kwemvelo, ikakhulukazi ngenxa yokwanda kwezinto zokusetshenziswa okukodwa eziholela ekungcolisweni kwemfucumfucu nasolwandle. Izingozi zamakhemikhali ziwumqondo obalulekile, njengoba ezinye izinto zokwakha zingase zikhishwe izinto zokudla, ikakhulukazi uma zishiswa ngendlela engafanele.

Ukuphinda usebenzise lezi ziqukathi kubeka nezinselelo. Akukho zonke izinto ezamukelwa ezinhlelweni zokuphinda zisetshenziswe zomphakathi, futhi ukungcoliswa okuvela ezinsalela zokudla kungavimbela izinqubo zokuphinda zisetshenziswe. Ngakho-ke, amabhizinisi akhuthazwa ukuba athathe izindlela eziqhubekayo, kuhlanganise nokukhetha iziqukathi ezenziwe ngezinto eziphindwayo noma ezitholakala emathunjini futhi zifundise abathengi ngendlela efanele yokulahla.

Iziqukathi ezingasetshenziswa futhi ezingadliwa kufanele zithobele imithetho eqinile yokuphepha njengaleyo ebekwe yi-FDA (Food and Drug Administration) e-United States kanye ne-LFGB (Lebensmittel- und Futtermittelgesetzbuch) eJalimane. Lezi ziqinisekiso ziqinisekisa ukuthi izinto zisezingeni eliphezulu lokuthintana nokudla ngqo, azinawo amakhemikhali ayingozi, futhi zilungele izinhlobo zokudla nezinga lokushisa ezihloselwe zona.

Inkampani iGuangdong Teguan Industrial Co., Ltd. ibonisa ukuzibophezela kulezi zindinganiso eziphakeme ngokuhlinzeka ngeziqukathi ezihambisana nezitifiketi zamazwe omhlaba zokuphepha kokudla. Izixazululo zenkampani zokupakisha ezisebenziseka kalula emvelweni, ezifanele ukudla, zakhelwe ngokucatshangelwa ukuphepha kwabathengi kanye nokusimama kwemvelo, okwenza zibe umlingani omethembayo embonini yokupakisha ukudla. Ukuze ufunde kabanzi mayelana nohlu lwemikhiqizo yabo kanye nezinqubo zabo ezisimeme, vakashela i-Imikhiqizo ikhasi.

Ukukhetha impahla efanele yesitsha sokudla esilahlayo kuyisinqumo esibalulekile kumabhizinisi okudla azibophezele ekuvikelekeni, ukusebenziseka kalula, kanye nesibopho semvelo. Ukuqonda umehluko phakathi kwezitsha ze-PP, PET, PS, kanye ne-PLA kuvumela izinqumo ezinolwazi ezihlangabezana nezidingo ezahlukahlukene zokudla ngenkathi kuncishiswa ubungozi kwezempilo nezemvelo.

Amabhizinisi afuna izixazululo zokupakisha ezithembekile, ezisezingeni eliphezulu, nezinobuntu kufanele bacabange ngobuchwepheshe beGuangdong Teguan Industrial Co., Ltd. Isipiliyoni sabo esibanzi nokuzinikela ekwenzeni izinto ezintsha kuqinisekisa ukuthi amaklayenti athola izitsha zokudla ezihlangabezana namazinga omthetho futhi zisekela imikhuba eluhlaza. Ngeminye imininingwane mayelana nokuzibophezela kwabo nezixazululo, vakashela i-Ikhaya kanyeMayelana Nathi amakhasi.
