Sekuyiminyaka engama-20 edlulileyo sasihlamba ngokucokisekileyo iifowuni ze-cellophane, zomise ebhaleni, ukuzisebenzisa ngokuphindaphindiweyo ukugcina iimveliso. Kodwa i-Stone Age isemva kwethu, kuba ngoku kukho ifilimu eyolule ukutya, apho unokugcina ukutsha kweemveliso kunye nenkcazo yabo ixesha elide, kokubili kwimpilo yemihla ngemihla nakwezorhwebo.
Namhlanje, ifilimu elulayo isetyenziselwa iinjongo ezahlukeneyo - ukupakisha impahla kwindawo yokusebenzela, ukulungiselela iimveliso zokupakisha xa zifakwe kwi-intanethi yokuthengisa, kwaye, ewe, ekhaya, xa kukho isidingo sokunciphisa ukufikelela komoya kwimveliso ukuze bangabi niphunga lefriji okanye vice versa , abazange bamnike.
Kukho iintlobo ezimbini zefilimu yokutya-iPVC ne-PE. Masifunde ukuba yiziphi iingenelo abanakho kunye nokokukhetha ukuba basebenzise ekhaya, kuba banexabiso elithile.
PVC welula ifilimu
Isifingqo se-PHV simele sichaze nje - yi-polyvinyl chloride. Sebenzisa le ngcaciso ukuze uqhagamshelane nokutya, kuba ayinakubungozi ngokupheleleyo kubantu, xa isetyenziswe ngokuchanekileyo.
Inzuzo ephambili yefilimu ye-PVC kukuba inesakhiwo esihle, esingabonakali kwiso, evumela ukuba umswakama kunye nomoya uphume. Le ndawo iyimfuneko apho kukutya okufudumele kufakwe kwifilimu, njengokuba kubhakabhaka.
Isonka esifudumele singapakishwa kwifilimu ngaphandle kokulinda ukupholisa. Ngethuba lokupakisha, iifom zokufakela ngaphakathi kwefilimu, ephuma ngokukhawuleza, iimveliso zikhangeleka zikhangele kwaye zithengiswa ngokuthengiswa kwicandelo lokuthengisa. Imimandla emikhulu yemveliso, kunye kunye nemiqulu yefilimu elula, isisetyenziselwa yona. Lo ngumnini wesandla onesisombululo esihle, apho umsebenzi ukhawuleza, kwaye ukupakisha kuya kuba nechaneke ngakumbi.
Ekubeni ixabiso lezinto ezinjalo liphezulu ngokwaneleyo, lisetyenziswe ngakumbi kwiimveliso zorhwebo, kodwa ukusetyenziswa kwekhaya, ukuthengwa kwexabiso okuncinci kwento yokupakisha kuthengwa, kodwa kananjalo akukho zakhiwo ezinobuncwane.
Tyalela ifilimu kwi-polyethylene
Kuba indlu siyithengisa ifilimu yexabiso le-polyethylene
Ngoku akukho mfuneko yokukhetha ngokucophelela izitya zokugcina ukutya kwifriji okanye ukudibanisa ubuchopho babo, njengoko kungcono ukuthutha isethi yokutya, umzekelo, ukuphumla. Ngomncediso wefrimu elula, unokwakheka umtya okanye utyhafise nayiphi na imveliso kwaye ungakhathazeki ngokhuseleko lwayo.
