Ngokufika kwehlobo, isimo sezulu esishisayo senze abantu banaka kakhulu ubusha nokuphepha kokudla.Kule sizini, ukudla okuqandisiwe sekuyinto ekhethwayo emindenini eminingi nakubathengi.Nokho, isici esibalulekile ekugcineni izinga nokunambitheka kokudla okuqandisiwe kuseqophelweni eliphezuluukupakisha ukudla okuqandisiwe. Ukupakisha ukudla okuqandisiweayidingi nje kuphela ukuthi ibe nezici ezingangeni amanzi kanye nokuvikela umswakama, kodwa futhi kumele ihlangabezane nezidingo zokuphepha nokudla ukongiwa.Okulandelayo, sizohlola izindinganiso eziyisisekelo zokupakisha ukudla okuqandisiwe kanye nendlela yokukhetha izinto zokupakisha ezifanele nezinqubo zokuqinisekisa ubusha nokuphepha kokudla.
Ukupakishwa kokudla okuqandisiweidinga ukuhlangabezana nala mazinga alandelayo:
1. Ukubekwa uphawu: Iukupakishwa kokudla okufriziwekumele ibe nokuvaleka kahle ukuze kuvinjwe umoya obandayo ukuthi ungangeni ngaphakathi kwephakeji, kanye nokuvimbela ukuhwamuka komswakama ekudleni noma ukungena komswakama wangaphandle.
2. I-Anti-freezing and cracking: Izinto zokupakisha kufanele zibe nokumelana okwanele emakhazeni nasekuqhekekeni, zikwazi ukumelana nokunwetshwa kweqhwa emazingeni okushisa aphansi, futhi zigcine ubuqotho bokupakishwa.
3. Ukumelana nokushisa okuphansi: Izinto zokupakisha kufanele zibe nokumelana okuhle kokushisa okuphansi futhi zikwazi ukumelana nokuguqulwa nokuwohloka endaweni eqandisiwe, kuyilapho kugcinwa ukuzinza kokupakisha.
4. Ukuba sobala:Ukupakishwa kokudla okuqandisiwengokuvamile kudinga ukucaca okuhle ukuze kube lula ukuqaphela kwabathengi ukubukeka kanye nekhwalithi yokudla.
5. Ukuphepha kokudla: Izinto zokupakisha kufanele zihambisane nezindinganiso zokuphepha kokudla, zingakhiphi izinto eziyingozi, futhi zingabi nemithelela emibi kwikhwalithi nokunambitha kokudla.
Izinto ezisetshenziswa kakhuluukupakisha ukudla okufriziwe:
1. I-Polyethylene (PE): I-Polyethylene iyinto evame ukusetshenziswa yepulasitiki enokumelana okuhle kokushisa okuphansi nokumelana nomswakama, ifaneleka ukwenza izinto zokupakisha ezifana nezikhwama zokudla ezifriziwe namafilimu.
2. I-Polypropylene (PP): I-Polypropylene enye impahla yepulasitiki evamile enokumelana okuhle kokushisa okuphansi kanye nokumelana namakhemikhali, okulungele ukwenza izinto zokupakisha ezifana nezinto zokuxhumana eziqandisiwe zokudla kanye nezikhwama ezivaliwe.
3. I-Polyvinyl chloride (PVC): I-PVC iyinto ethambile futhi elula yokucubungula izinto zepulasitiki ezinokumelana okuhle kokushisa okuphansi kanye nokumelana nomswakama, ezifanele ukwenza amabhokisi okupakisha, amafilimu, njll ukudla okufriziwe.
4. I-Polyester (PET): I-polyester iyimpahla yepulasitiki enezakhiwo ezinhle kakhulu zomzimba kanye nokumelana nokushisa okuphansi, ifaneleka ukwenza izinto zokuxhumana eziqandisiwe Zokudla, amabhodlela nezinye izinto zokupakisha.
5. Ucwecwe lwe-Aluminium: Icwecwe le-aluminium linezinto ezinhle kakhulu zokuvikela umswakama kanye nezindawo zokushisa ezishisayo, futhi ngokuvamile zisetshenziselwa ukwenza izikhwama zokupakisha, amabhokisi, njll. ukudla okufriziwe.
Lapho ukhethaizinto zokupakisha zokudla okufriziwe, kuyadingeka ukucabangela ngokucophelela izici ezifana nezici ezithile zokudla, izidingo zokushisa kwesitoreji, nemithetho neziqondiso, nokuqinisekisa ukuthi izinto ezikhethiwe ziyahlangabezana nezindinganiso zokuphepha kokudla.
