Abesifazane abaningi besifazane basebenzisa ifilimu yokupakisha imikhiqizo yokudla. Kungakugoqa inyama, inhlanzi, amakhowe, amasoso kanye nemikhiqizo yobhakabhaka, izinkukhu ezinzima, imifino, imifino nezithelo. Lephakethe inezinzuzo eziningi phezu kwe-cellophane yendabuko. Masifunde kabanzi mayelana nefilimu yokudla, ukusetshenziswa kwayo okusebenzayo kanye nezakhiwo eziwusizo.
Izakhiwo zokupakisha ifilimu yokudla
Ifilimu yokufakelwa kokudla ayikufanelanga ukuthandwa okunjalo ngoba:
- kusiza ukulondoloza isethulo isikhathi eside;
- uyayilondoloza "ekuphefumuleni" nokumisa;
- Kuyinto elula kakhulu ukusingatha, ngoba kulula ukungahambisani nokuphepha ngokuqinile.
Ifilimu enjalo ingenziwa nge-polyethylene (PE) noma i-polyvinyl chloride (PVC). Okukugcina kuhlanganisa ukufakwa kwemikhiqizo isikhathi eside sokugcina. I-PVC inempahla emangalisayo yokuvumela i-oxygen ngaphakathi kwefilimu, iveza umswakama kanye ne-carbon dioxide ngaphandle. Ngenxa yalesi microstructure yefilimu, imikhiqizo (ikakhulukazi ebhakabhakeni) ingafakwa emaphaketheni ashisa, futhi ukunciphisa ngeke kube ngaphakathi ngaphakathi ifilimu.
Ngokuqondene nefilimu ye-polyethylene, ngokuvamile ishibhile futhi ifanele kuphela ukugcina isikhathi esifushane, ngoba ivikela kuphela umswakama kanye namafutha angaphandle avela ngaphandle. Ngaphezu kwalokho, ifilimu inikeza imikhiqizo, ikakhulukazi imifino nezithelo ezintsha, ukubukeka okubonakalayo nokukhanya.
Ifilimu yokudla engenakushisa nokungaqandiswanga yenziwe nge-polyolefin. Kukhulu kakhulu futhi kunwebeka. Le filimu ingasetshenziswa ukufisa ukudla ekamelweni nokulungisa ukudla kuhhavini ye-microwave . Uma ungabaza ukuthi kungenzeka yini ukushisa ifilimu yokudla, qaphela: lo mzuzu kufanele uboniswe ephaketheni, kanye nokushisa okuphezulu kokushisa. Yiqiniso, zonke lezi zinhlobo zefilimu zilahlwa futhi zenzelwe, ngokulandelana, ngokusetshenziswa okukodwa kuphela. Ukudla kwehlisa ifilimu akusetshenziswanga kuphela empilweni yansuku zonke, kodwa nasemabhizinisini ezentengiselwano, emkhakheni wesidlo somphakathi, embonini yokudla, njll.
