Imigca icacile kwaye igudileyo, iyanciphisa ixesha lokupompa, ukupompa kucocekile, kwaye irhasi inokukhutshwa kwimizila eyandisa kuzo zonke iinkalo. Umphezulu ochongiweyo wamkela i-PE + PA ye-seven-layer co-extrusion (usebenzisa ipateni yesikweri, ifilimu egcweleyo yobubanzi obugcweleyo, akukho angle efileyo yokutsalwa komoya), indawo egudileyo ithatha inkqubo edibeneyo ye-PE + PA (ukukhanya okuphezulu, ukusetyenziswa kwezinto ezikhuselekileyo, ukuphela okuphezulu. kunye nesitayile)
