Pambuyo pake pepalali limaziziritsidwa mwa kulidutsa m'ma rollers angapo, omwe samangoziziritsa zinthuzo komanso amasalala ndikusalala pamwamba pake, kuonetsetsa kuti zimagwirizana.
3.Kupaka: Pambuyo poziziritsa, pepala la PVC limadutsa mu njira yophikira yomwe imadziwika kuti knife-over-roll coating.

Chophikirachi chimawonjezera chitetezo cha nsaluyo ndipo chimathandizira kuti ikhale yolimba.
4. Kukonza Kalendala: Kenako pepala la PVC lophimbidwa limakonzedwa kudzera mu ma calendarling rollers, omwe amagwiritsa ntchito mphamvu ndi kutentha. Gawoli ndi lofunika kwambiri popanga malo osalala komanso ofanana komanso kukulitsa mphamvu ndi kulimba kwa nsaluyo, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana.
