Abafazi abaninzi basekhaya basebenzisa ifilimu yokupakisha iimveliso zokutya. Ingakwazi ukumboza inyama, intlanzi, amakhowa, i-sausages kunye nemveliso yeebhakabhaka, iichizi ezinzima, imifino, imifuno kunye neziqhamo. Le phakheji ineenzuzo ezininzi kwi-cellophane yendabuko. Makhe sifunde ngakumbi ngefilimu yokutya, isicelo sayo esisebenzayo kunye nezixhobo ezincedo.
Iipropati zokupakisha ifilimu yokutya
Ifilimu yokupakishwa kokutya ayikufanelekanga ukuthandwa okunjalo kuba:
- unceda ukulondoloza ukubonisa ixesha elide;
- uyayikhusela "kwi-winding" kunye nokomisa;
- Kukulungele ukusingatha, kuba kulula ukukhutshwa kwaye ichaneke ngokukhuselekileyo.
Ifilimu enjalo ingenziwa nge-polyethylene (PE) okanye i-polyvinyl chloride (PVC). Izinto zokugqibela ziquka ukufakwa kwemveliso ngexesha elide lokugcina. I-PVC inomhlaba omangalisayo wokuvumela i-oksijini ngaphakathi kwefilimu, ukubonisa umswakama kunye ne-carbon dioxide ngaphandle. Ngenxa yesikhululo esincinane sefilimu, iimveliso (ngokukodwa kubhakabhaka) zingafakwe emotweni, kwaye ukulungiswa akuyi kufaka ngaphakathi ngaphakathi kwefilimu.
Ngokubhekiselele kwifilimu ye-polyethylene, ngokuqhelekileyo ixabiso eliphantsi kwaye lifanele kuphela ukugcina ixesha elifutshane, kuba likhusela kuphela ukunyuka kwamanye amazwe kunye nokuvumba kwamanye amazwe. Ukongeza, ifilimu inikeza iimveliso, ngokukodwa imifuno kunye neziqhamo, ukubonakala okubonakalayo kunye nokukhanya.
Ifilimu yokutya engaphephekiyo yokushisa nokungabikho kwamaqabunga yenziwe nge-polyolefin. Kuninzi kakhulu kwaye i-elastic. Le fayili ingasetyenziselwa ukuphelisa ukutya ekamelweni kunye nokulungiselela ukutya kwi- oven microwaves . Ukuba ungathandabuzeki ukuba kunokwenzeka yini ukutshisa ifilimu yokutya, qaphela: lo mzuzu kufuneka uboniswe kwiphakheji, kunye nokushisa okuphezulu. Ewe, zonke ezi ntlobo zefilimu ziyalahlwa kwaye zenzelwe, ngokulandelanayo, ukusetyenziswa kuphela. Ukutya ukunciphisa ifilimu ayisebenzisi nje kuphela kwimpilo yemihla ngemihla, kodwa nakwiimashishini zorhwebo, kwicandelo lokutya kwidlangalaleni, kwicandelo lokutya, njl.
