Ikhoyili yensimbi i-ppgl isifushaniso sensimbi ye-galvalume ependwe kusengaphambili, isebenzisa insimbi ehlanganiswe nge-aluminium engu-galvanized njenge-substrate.Ngemuva kokwelashwa kwangaphambili (ukususwa kwamakhemikhali kanye nokwelashwa kokuguqulwa kwamakhemikhali), indawo engaphezulu embozwe ngongqimba noma izendlalelo ezimbalwa zokumboza, ngokubhaka nokuphulukiswa, bese iba yi-PPGL.
Ifilimu kapende esingayenza 10-30microns.Lapho ifilimu kapende iphakeme, iba yinde impilo yesevisi yombala.
Izinto zokudweba ziyi-PE, SMP, HDP, PVDF, ects.
