Kuleyl ka dib, emulsion-ka xasaasiga ah ee cadaadiska ayaa si siman u faafa si uu u sameeyo lakab koollo ah oo u dhexeeya 8μm ilaa 28μm. Samee duubista hooyada ee BOPP, oo ah shirkad warshadeed fudud, sahayda dadweynaha ee aan looga maarmin shirkadda iyo nolosha gaarka ah, waddanku ma laha halbeeg dhammaystiran ee warshadaha cajaladaha. Waxa jira hal halbeeg oo warshadeed oo BOPP ah oo cadaadis-xasaasi ah cajalad dhejis ah oo lagu xidho. Ka dib marka filimka asalka ah ee BOPP lagu daweeyo korona koronto-sare leh, dhinac ka mid ah dusha sare ayaa noqda mid qallafsan, ka dibna koollada ayaa lagu dhejiyaa si ay u sameeyaan duub hooyooyin ah, ka dibna loo qaybiyo duubo yaryar oo kala duwan oo kala duwan by mashiinka wax lagu gooyo. taas oo ah waxa aan isticmaalno maalin walba Tape out. Emulsion xabagta xasaasiga ah ee cadaadiska, qaybta ugu weyn waa butyl ester. 1. Tilmaamaha wax-soo-saarka Tilmaamaha cajaladda BOPP ee daboolka waxaa lagu muujiyay "ballaaran × dhererka × dhumucda", halkaasoo "ballaadhka" uu yahay ballaca cajaladda, guud ahaan lagu muujiyay mm ama cm, guud ahaan ≥10mm. Horraantii 1980-meeyadii, tilmaamo guud waxay ahaayeen: 72mm, 60mm, 50mm, 30mm, iwm.; beryahan dambe, waxa si tartiib tartiib ah loogu beddelay: 60mm, 48mm, 45mm, 40mm, 30mm, iwm.; "Length" waa dhererka guud ee cajaladda ka dib marka la dhaawaco, guud ahaan lagu muujiyay "m" ama "code" (1 yard = 0.9144m), dhererka guud waa 50m, 100m, 150m, 200m, 500m, iwm.; dhumucdiisuna waxay tilmaamaysaa wadarta dhumucda filimka asalka ah ee BOPP + lakabka xabagta (cutub: micron, μm), sida caadiga ah loo isticmaalo 45-55μm. Sida "50mm × 100m × 50μm" Habka xisaabinta ee qiimaha halbeegga ee duub kasta oo cajalad ah: warshadaha cajaladaha sida caadiga ah waxay isticmaalaan "RMB / mitir laba jibaaran" si loo xisaabiyo qiimaha cajaladda, ka dibna "qiimaha cajalad kasta = width M furin sharci darro ah.
