PVA ayaa helay isticmaalka ballaaran ee daaweynta ee dusha warqad sida ay leedahay adhesiveness fiican iyo dispersibility iyo ma saamayn doonto hantida galalka kale lagu daro. Faa'iidooyinka PVA la isticmaalayo, Xoog oogada (printability); Xoog weheliyaan Z-dhidibka (warqad xoog gudaha), iska caabin ah oo laabma, iska caabin sugi lahaayeen, macaanaa soo hagaagaya, glossiness dusha hagaagaya, kor caabiga saliid iyo dareeraha (hantida caqabad).
