Ingabe I-PE Plastic Iphephile Ukudla?

Ipulasitiki ye-Polyethylene (PE), into esetshenziswa kakhulu ukupakisha ukudla, idonsele ukunakwa ngokuhlukahluka kwayo nokuphepha. Ipulasitiki ye-PE iyi-polymer eyakhiwe amayunithi e-ethylene, aziwa ngokuzinza kwawo nokungaphindiseli. Lezi zakhiwo zenza i-PE ibe inketho efanelekile ekusetshenzisweni kwebanga lokudla, njengoba ingangenisi amakhemikhali ayingozi ekudleni, ngisho nalapho evezwe emazingeni okushisa ahlukene.

Izifundo Zokuphepha Nemithethonqubo

Ucwaningo olunzulu kanye nemithetho eqinile iqinisekisa ukuthi ipulasitiki ye-PE yebanga lokudla iphephile ukuthintana nokudla. Ucwaningo luye lwabonisa ukuthi ipulasitiki ye-PE ayikhiphi izinto eziyingozi ngaphansi kwezimo ezijwayelekile zokusetshenziswa. Izikhungo ezilawulayo ezifana ne-US Food and Drug Administration (FDA) kanye ne-European Food Safety Authority (EFSA) zisungule imihlahlandlela namazinga okumele ipulasitiki ye-PE ihlangabezane nayo ukuze ifakwe kusigaba sokudla. Lawa mazinga ahlanganisa ukuhlola ukufuduka kwamakhemikhali, ukuqinisekisa ukuthi noma yikuphi ukudluliselwa kwezinto zisuka epulasitikini ziye ekudleni zihlala ngaphakathi kwemingcele ephephile.

Izicelo Ezivamile Ekufakweni Kokudla

Ipulasitiki ye-PE isetshenziswa kabanzi kumafomu ahlukahlukene wokupakisha ukudla, kufaka phakathiIzikhwama ze-PE, izikhwama uziphu, futhiizikhwama ze-ziplock. Lezi zixazululo zokupakisha zinikeza ukumelana nomswakama okuhle kakhulu, ukuguquguquka, nokuqina, okuzenza zifanelekele ukugcina imikhiqizo eminingi yokudla. Izikhwama ze-PE, isibonelo, zivame ukusetshenziselwa umkhiqizo omusha, ukudla okulula, nokudla okufriziwe ngenxa yekhono lazo lokulondoloza ubusha kanye nokwelula impilo yeshalofu.

Ukuqhathanisa namanye amaPlastiki

Uma kuqhathaniswa namanye amapulasitiki, afana ne-polyvinyl chloride (PVC) ne-polystyrene (PS), ipulasitiki ye-PE ithathwa njengephephile futhi ihambisana nemvelo. I-PVC, isibonelo, ingakhulula amakhemikhali ayingozi njengama-phthalates nama-dioxin, ikakhulukazi uma kushisa. Ngokuphambene, ukwakheka kwamakhemikhali okulula kwe-PE plastic kanye nokuzinza kuyenza kube ukukhetha okuthandwayo kokupakishwa kokudla, njengoba ibeka ubungozi obuncane bokungcoliswa.

Ukusekela Idatha Nocwaningo

Idatha evela ezifundweni zomkhakha isekela ukuphepha kwepulasitiki ye-PE. Isibonelo, ucwaningo olwenziwa yi-EFSA lwathola ukuthi ukufuduka kwezinto ezivela epulasitiki ye-PE zibe ukudla kwakungaphakathi kwemingcele yokuphepha emisiwe. Ukwengeza, ukuphinda kusetshenziswe kabusha okuphezulu kwepulasitiki ye-PE kuthuthukisa ngokwengeziwe ukukhanga kwayo, njengoba ingacutshungulwa kahle ibe yimikhiqizo emisha, kunciphise umthelela wemvelo.

Ekuphetheni,Izikhwama ze-PE, izikhwama uziphu, futhiizikhwama ze-ziplockezenziwe ngepulasitiki ye-PE yezinga lokudla ziyizinketho eziphephile nezithembekile zokupakishwa kokudla. Ukuzinza kwabo kwamakhemikhali, ukuhambisana nezindinganiso zokuphepha, kanye nokusetshenziswa kabanzi embonini kubenza babe inketho enhle kakhulu kubathengi abafuna ukugcina nokuvikela ukudla kwabo. Ukuze uthole ulwazi olwengeziwe ngepulasitiki ye-PE kanye nezicelo zayo, sicela ubheke izinsiza ezinikeziwe.
