Filimka Dufcadda EVA
ZonpakTMEVAfilimka ka mid noqoshada dufcaddiiwaa nooc gaar ah oo filim baakad ah oo leh bar dhalaalaysa oo gaar ah. Waxaa inta badan loo adeegsadaa mashiinka wax-baakaynta ee FFS (foom-buuxinta-seal) si loo sameeyo baakado yar yar (100g-5000g) ee caagga lagu daro ama kiimikooyinka. Sababtoo ah hantida filimka ee dhibicda dhalaalka hooseeya iyo iswaafajinta wanaagsan ee caag iyo caag ah, baakadahan yar yar ayaa si toos ah loogu dhejin karaa qasaha gudaha inta lagu jiro habka isku dhafka, iyo bacaha ayaa dhalaali doona oo si buuxda u kala firdhi doona isku dhafka sida qayb waxtar leh. Waxay u keentaa ku raaxaysashada isticmaaleyaasha walxaha waxayna meesha ka saaraysaa baakaynta qashinka.
Dhibcaha dhalaalka ee kala duwan ayaa diyaar u ah sida macaamiisha looga baahan yahay. Qalabka kiimikada ee xasilloon iyo xoogga sare ee jirka ee filimka ayaa ka dhigaya mid ku habboon inta badan kiimikooyinka caagga ah iyo mashiinnada baakadaha tooska ah.
