Izikhwama zokudla zeplastiki seziye zaba yinto ejwayelekile emakhishini emhlabeni jikelele ngenxa yokuba lula, intengo efanele, kanye nokusebenza okuningi. Lezi zikhwama zenza kube lula ukugcina, ukuthutha, nokuphinda zishiswe ukudla, okwenza zibe zibalulekile ezindlini ezinomsebenzi omningi kanye nezimboni zokudla. Ubulula bazo bokuphatha kanye nokumelana nezimo kuphinde kube nomthelela ekuthandeni kwazo, ikakhulukazi uma kuqhathaniswa nezinketho zengilazi noma zensimbi. Ngaphezu kwalokho, izinguquko ezifana nezikhwama zokudla eziphephile zokushisa emshinini wokushisa nokukhiqizwa kweplastiki okungashiswa emshinini wokushisa zikhulise kakhulu ukusebenza kwazo ngokuvumela ukushiswa ngqo ngaphandle kokudlulisela okuqukethwe kwezinye izitsha. Nokho, ngasikhathi sinye nalezi zinsiza, ukukhathazeka ngempilo nokuphepha kwezikhwama zokudla zeplastiki kuvele, kukhuthaza uphenyo olunzulu ngemiphumela yazo yesikhathi eside empilweni yomuntu.

Ukusetshenziswa kabanzi kwezikhwama zeplastiki kubandakanya izidingo ezahlukene zokugcina ukudla, kuhlanganise nezixazululo zokugcina ukudla isikhathi eside ezifana nezikhwama ze-mylar nezikhwama ezisetshenziswayo ezenziwe nge-polypropylene (PP5), ezaziwa ngezici zazo zokufakwa emshinini wokupheka. Lezi zinguquko zenze izikhwama zeplastiki zibe yingxenye ebalulekile yokugcina ukudla kwanamuhla nokwenza kube lula. Kulesi sihloko, sizohlola izingozi zempilo ezihambisana nezikhwama zokudla zeplastiki, sihlole ukuvezwa nezilinganiso zezingcuphe, sihlole izimpendulo zomhlaba, futhi siphakamise ezinye izinketho eziphephile ukusiza abathengi benze izinqumo ezihlakaniphile.

Izifundo zakamuva zesayensi zikhulume ngokuqhubekayo ngokuqhubeka kokukhathazeka ngamakhemikhali aphuma ezitsheni zokudla zeplastiki ziya kokudla ezigcinayo, ikakhulukazi uma zikhuluma nezinga lokushisa noma ukugcinwa isikhathi eside. Ezinye zeplastiki ziqukethe ama-additives afana ne-bisphenol A (BPA) kanye ne-phthalates, okwaziwa njengama-endocrine disruptors. Lezi zinto zingaphazamisa imisebenzi ye-hormonal futhi zixhunywe nezinkinga ezahlukene zempilo, kuhlanganise nezinkinga zokukhulelwa, izinkinga zokuthuthuka, futhi ngisho ne-cancer. Izinqubo ezisemva kwalezi zingozi zifaka phakathi ukuhamba kwamakhemikhali ukusuka kuplastiki kuya kokudla, ikakhulukazi kokudla okunezinyama nezokudla ezinokushisa, okungakwazi ukumunca lezi zinto eziyingozi kalula.

Izikhwama zeplastiki ezikwazi ukufudunyezwa, nakuba zenzelwe ukuhlinzeka ngodlame lokufudumeza, zingase zandise ukuchithwa kwemichiza uma zingezona ezisezingeni eliphezulu noma zingabhalwanga ngokusobala njengezikhwama eziphephile zokufudumeza. Ngalesi sizathu, ukukhetha imikhiqizo ehlolwe futhi eqinisekisiwe yokusetshenziswa kwe-microwave kubalulekile ukuze kuncishiswe izingozi zempilo. Ngaphezu kwalokho, ukugcina ukudla isikhathi eside usebenzisa ama-plastics angahloselwe lezi zinhlelo kungakhuphula ukuvezwa kumakhemikhali abalulekile, kugcizelela ukubaluleka kokwazi ukwakheka kwemathiriyeli nezindinganiso zokuphepha zezikhwama ezisetshenziswayo.

Izingozi zempilo ezihambisana nezitsha zokudla zeplastiki zinciphisa kakhulu ngokuhamba kwesikhathi nokuphindaphinda kokub exposure. Ukusetshenziswa njalo kwezitsha zeplastiki ezivumelana ne-microwave zokushisa ukudla kungaholela ekuthinteni okuphindaphindiwe nezinto ezimbi ezingase zibe yingozi. Ngokufanayo, ukugcina ukudla isikhathi eside ezitsheni zeplastiki ngaphandle kokuvuleka kahle noma ukulawula izinga lokushisa kungakhuphula ukuhamba kwezinto eziyingozi kokudla. Izifundo ze-epidemiological zikhombisa ukuthi ukuhamba kwesikhathi kokub exposure kulezi zinto kungakhuphula izingozi zezinhliziyo nezinye izimo zempilo eziphindaphindiwe ngokuhamba kwesikhathi.

Isibonelo, iziqukathi ze-polypropylene ezibhalwe njenge-PP5 ezivumelana ne-microwave ngokuvamile zicatshangwa ukuthi ziphephile ngenxa yokuzinza kwazo kwezemithi; nokho, noma lezi zidinga ukusetshenziswa ngokucophelela nokulandela imihlahlandlela yomkhiqizi. Ukuhlolwa kwezingozi kuncoma ukunciphisa ukusetshenziswa kwezinto zokwenziwa zokugcina ukudla okushisayo nokukhetha ezinye izinketho lapho kungenzeka. Ukuqonda lezi zimo zokub exposure kuvumela abathengi ukuthi banciphise izingozi zempilo ngenkathi besathola inzuzo ekusebenzeni kwezikhwama zokwenziwa.

Ngenxa yokukhathazeka okukhulayo ngempilo kanye nemvelo, amazwe amaningi anikezele imithetho elinganiselayo noma evimbela izinhlobo ezithile zepulasitiki ekupakisheni ukudla. Isibonelo, i-European Union, inemithetho eqinile nge-BPA ezintweni ezithintana nokudla futhi ikhuthaza ukusetshenziswa kwezindlela eziphephile. Amanye amazwe aqale nemikhankaso yokuqwashisa umphakathi ekhuthaza abathengi ukuthi banciphise ukusetshenziswa upulasitiki futhi bashintshele ezixazululweni zokugcina ezinganaki umonakalo emvelweni.

Ngokuphambene, imakethe yaseMelika iqhubeka nokuthembela kakhulu ezitsheni zokudla zeplastiki, nakuba kukhona ukwanda kokucindezela ukuze kutholakale izinto eziphephile kanye nokucaciswa ngokuqukethwe kwamakhemikhali. Izinkampani ezifana neGuangdong Teguan Industrial Co., Ltd. ziseqhulwini kwalolu shintsho, zithuthukisa imikhiqizo yokupakisha engaboli futhi efanele ukudla ehambisana nezitifiketi ze-FDA ne-ISO 9001. Ukuzinikela kwabo ekusimameni nasekuphepheni kubonisa ukuthi abaholi bezimboni bangathinta kanjani ukuthrendwa kwemakethe ukuze kuthuthukiswe imiphumela yokuphila kwabathengi. Ukuze uthole okwengeziwe ngezixazululo zabo zokupakisha ezisunguliwe, vakashela ku-Ikhaya ikhasini.

Abathengi abafuna ukunciphisa izingozi zezempilo ezihambisana nezitsha zokudla ezenziwe ngepulasitiki kufanele bacabange ngamasu amaningana asebenzayo. Okokuqala, ukukhetha izitsha ezibhalwe njengezitsha eziphephile ze-microwave kuqinisekisa ukuthi umkhiqizo uhlolwe ukuthi kukhona yini ukudluliselwa kwamakhemikhali ngesikhathi sokufudumeza. Ezinye izindlela ezifana nengilazi, insimbi engagqwali, noma izitsha ezingadala ukubola ngendlela eqinisekisiwe zinikeza izindlela eziphephile zokugcina isikhathi eside, ikakhulukazi ekudleni okunamafutha noma okune-asidi okuthambekele ekumunceni amakhemikhali kusuka epulasitiki.

Ngaphezu kwalokho, ukusebenzisa amabhakede e-mylar okugcina ukudla isikhathi eside kungahlinzeka ngesisombululo esisebenzayo sokugcina ukudla ngaphandle kokubhekana nezinto eziyingozi ezihlobene nepulasitiki. Uma ukusetshenziswa kwepulasitiki kungagwenywa, ukukhetha imikhiqizo yekhwalithi ephezulu eyenziwe ngama-plastics e-PP5 angafakwa emshinini wokushisa nokugwema ukuphinda kusetshenziswe iziqukathi ezisetshenziswayo kunganciphisa ukub exposure. Izindlela ezifanele zokugcina, ezifana nokugwema ukushisa ama-plastics angakhelwanga ngempela ukuze asetshenziswe emshinini wokushisa nokungagcini ukudla okushisayo eziqukathini zeplastiki isikhathi eside, nazo zibalulekile. Ukuze uthole ukukhethwa okubanzi kwemikhiqizo yokupakisha ephephile nephumelelayo, hlola i-Imikhiqizo enikezwe yiGuangdong Teguan Industrial Co., Ltd.

Izikhwama zokudla zeplastiki zinikeza ukuhamba kalula okungaphikiswa kodwa ziza nezingozi zempilo ezingaba khona ngenxa yokuphuma kwemichiza, ikakhulukazi uma zisetshenziswa ngendlela engafanele. Ukuqonda lezi zingozi, ukuhlola amazinga okuthintwa, nokuhlala unolwazi ngezindlela zokulawula emhlabeni jikelele kuvumela abathengi ukuba benze izinqumo eziphephile, eziphilile. Ngokubeka phambili izikhwama ezenziwe ngezinto eziphephile, ukulandela imihlahlandlela yokusetshenziswa efanele, nokucabangela ezinye izinketho eziluhlaza, abantu bangavikela impilo yabo futhi babe negalelo ekugcineni kwemvelo.

I-Guangdong Teguan Industrial Co., Ltd. ibonisa ubuholi embonini ngokuhlinzeka ngezixazululo zokupakisha ezintsha, eziphephile, nezinganaki umonakalo emvelweni. Ukuzinikela kwabo ekuqinisweni nasekuqiniseni kusekela abathengi namabhizinisi ngokufanayo ekushintsheni ezindleleni zokugcina ukudla eziphephile. Funda kabanzi ngomsebenzi wabo kanye nobuchwepheshe babo ekhasini le-Mayelana Nathi ikhasini.

Guangdong Teguan Industrial Co., Ltd. iyinkampani ehamba phambili ekhethekile ezixazululweni zokupakisha ezihambisana nemvelo enolwazi olungaphezu kweminyaka engu-23. Iphothifoliyo yemikhiqizo yabo ifaka phakathi iziqukathi ezitholakala emvelweni, ukupakishwa okwenziwe ngokwezifiso, nezixazululo ezihambisana nokudla ezihlangabezana nezindinganiso eziqinile ze-FDA ne-ISO 9001. Ezinikele ekwakhiweni, ekusimameni, nasekuphathweni kokuphepha kwabathengi, Guangdong Teguan Industrial Co., Ltd. iqhubeka nokuthuthukisa imboni yokupakisha ngokuhlinzeka ngezinketho ezinciphisa umthelela emvelweni ngenkathi kuqinisekiswa ukuvikelwa kwempilo. Ukuze uthole izibuyekezo zakamuva ngemikhiqizo yabo nezinhlelo, vakashela kuIzindaba isigaba.
