Ifilimu yePVC, emele iPolyvinyl Chloride, yiplastiki eyomeleleyo nehlala ixesha elide eneempawu ezibalaseleyo zokuthintela amanzi. Iifilimu ze-PVC ziqhele ukusetyenziswa ekupakheni, ukwakhiwa, kunye nezicelo zendlu. Kwishishini lokupakisha, iifilimu zePVC zisetyenziswa kakhulu ukwenza iingxowa zeplastiki, iibhokisi zokupakisha, kunye nemikhono ecacileyo. Bakhusela ngokufanelekileyo iimveliso kumswakama, uthuli, kunye nokungcola. Ukongeza, iifilimu zePVC zinokuguquguquka okuhle kunye nokuguquguquka, zizenza zilungele ukwenza iimveliso zokupakisha zeemilo ezahlukeneyo kunye nobukhulu. Kwintsimi yolwakhiwo, iifilimu zePVC zisetyenziselwa ukwenza amakhethini, iiwallpapers, kunye nezigqubuthelo zomgangatho, njengoko kulula ukuzicoca, zihlala ixesha elide, kwaye ziyakwazi ukumelana nokufuma.

Ifilimu ye-PEVA, emfutshane ye-Polyethylene Vinyl Acetate, yiplastiki ehambelana nokusingqongileyo eyaziwayo ngenxa yendalo yayo engeyiyo ityhefu. Iifilimu ze-PEVA zinobuninzi obuhle kunye nokuguquguquka, ukuchasana ngokufanelekileyo nokungena kwamanzi kunye nezivumba. Ke, zisetyenziswa kakhulu kwimizi-mveliso yendlu kunye nekhaya. Iifilimu zePEVA zisetyenziselwa ukwenza izigqubuthelo zothuli, iikhethini zeshawa, amalaphu etafile, kunye namagquma oomatrasi, phakathi kwezinye iimveliso zasekhaya. Iifilimu ze-PEVA zikwasebenza njengezinto zokupakisha ukutya ngenxa yokungakhutshwa kwazo kweekhemikhali eziyingozi, ziqinisekisa ukhuseleko lwazo kwimpilo yabantu.

Impahla engangeni manzi sesinye isicelo esibalulekileyo sePVC kunye neefilimu zePEVA. Kwimidlalo yangaphandle kunye neendawo zokusebenza, iimpahla ezingenamanzi zidlala indima ebalulekileyo ekukhuseleni umzimba kumanzi emvula kunye nokufuma. Ezi mpahla ziqhele ukwenziwa ngeefilimu ezingenamanzi ukuqinisekisa ukuba abanxibi bahlala bomile kwaye bekhululekile. Iifilimu ze-PVC kunye ne-PEVA zidlala indima ebalulekileyo kwiimpahla ezingenamanzi, njengoko iimpawu zabo zokukhusela amanzi zithintela amanzi ukuba angangeni ngelaphu, ngokufanelekileyo ukukhusela umzimba kwiimeko ezifumileyo. Kwangaxeshanye, ezi filimu zibonisa ukuphefumla, zivumela ukufuma komzimba kunye nokubila ukuba kuphume umphunga, ngaloo ndlela kugcine amava okunxiba akhululekileyo.
