Ifilimu ikhiqizwa inqubo yokuphonsa, futhi i-polyethylene impahla eluhlaza yenziwe ngepulasitiki futhi ikhishwe ngenqubo yokufaka i-tape;Le nto yengeza izinto ezingavuthiwe ezinwebekayo eziphezulu kufomula yokukhiqiza, futhi isebenzisa irola yokubumba enemigqa ekhethekile ukwenza ifilimu ibe namaphethini.Ngemuva kokulungiswa kwenqubo, ifilimu ekhiqiziwe inesisindo esiphansi esiyisisekelo, umuzwa wesandla esithambile kakhulu, izinga eliphezulu lokuqina, ingcindezi ephezulu ye-hydrostatic, ukunwebeka okuphezulu, isikhumba esinobungane, ukusebenza kwesithiyo esiphezulu, ukumelana okuphezulu kwe-sepage nezinye izici, ezingahlangabezana nezimpawu ezahlukahlukene zamagilavu. ungangeni manzi.
