Filimka adag ee PVC-ga, waxaa ugu wanaagsan in la isticmaalo nooca ganaaxa 6 ama 7 resin, in kasta oo fiilada iyo fiilada isku xirka filimka la dhimi karo, iska caabbinta jirku ma aha mid aad u sarreeya sida 2 ama 3 resin, laakiin 7 resin moolding, wax soo saarka dhaqanka ayaa caddeeyey in isticmaalka 2 ama 3 resin, waa ay adag tahay in la sameeyo, PVC adag wax soo saarka film shrinkable adag oo jajaban, aan la laalaabi karaa oo la giringiriyey.
Marka balaastiga la isticmaalo, heerkulka kulaylka ee hoos u dhaca ayaa hoos u dhacaya kororka maadada balaastikada.Tusaale ahaan, isticmaalka joojinta nooca 3 budada dufanka geedka PVC, ku darida balaastiigga DOP ee 30-50 PHR, waxay noqon kartaa tensile biaxial qiyaastii 70 ℃, alaabteedana way yareyn kartaa qiyaastii 40 ℃, oo aan awoodin in la ilaaliyo maalmo kulul.Waxaa intaa dheer, iyada oo kororka maadada balaastikada, iska caabbinta jirka ee gacanta kulaylka-yar ee fiilada iyo fiilada ayaa hoos u dhacda.Sidaa darteed, marka aan isticmaalno PVC-ga-kulul-ku-kulul ee fiilooyinka iyo kala-goysyada fiilooyinka, waxaan wali isticmaalnaa nooca 6 ama 7 resins kuwaas oo sahlan in la farsameeyo.Si loo hagaajiyo dahaarka, waxaan isticmaalnaa qaboojiyaha kulaylka oo ay weheliyaan saddex milix iyo laba milix ah oo si habboon u wanaajinaa dhumucda filimka si loo hubiyo xayndaabka.P83 caag nitrile ah ayaa leh mashiin wanaagsan, barti, iska caabin qabow, oo wanaajin kara xoogga, hagaajinta iska caabin dildilaaca ee alaabta PVC.Firfircoon CaCO3 waxay inta badan wanaajisaa dahaarka iyo dib u dhaca ololka alaabta waxayna yaraynaysaa qiimaha.
