Ifilimu ikhiqizwa inqubo yokuphonsa, ikakhulukazi isebenzisa i-polyethylene enezici ezihlukene zokuxuba kanye ne-plasticizing kanye ne-extrusion ngokusebenzisa inqubo yokuphonsa.Ifomula ingashintshwa ngokuya ngezidingo zamakhasimende, futhi isisindo segram, umbala, ukuqina kokuzwa, kanye nephethini yokuma kungalungiswa., Kungenziwa ngokwezifiso amaphethini wokuphrinta.Lo mkhiqizo ulungele inkambu yokupakisha, unomuzwa oqinile, amandla aphezulu, ukuphakama okuphezulu, ukucindezela okuphezulu kwe-hydrostatic nezinye izinkomba zomzimba.
