Umgangatho weplastiki womthi we-PE&PP kukuba izinto ezidityanisiweyo zomthi-plastiki zisebenza ngezixhobo ezahlukeneyo zokuxuba, ukusuka kumdlalo, iimveliso ezikhuphayo, ukuxuba izinto eziluhlaza kwifomyula ethile, ukwenza amasuntswana omthi-plastiki embindini, uze emva koko ucinezele iimveliso. Kwaye kule mihla, kusetyenziswa indlela enamanyathelo amabini ngoku, ukusetyenziswa ngokubanzi kwe-double-cone-okanye i-two-extruder extruder granulation, uze emva koko iimveliso ze-double-cone okanye i-single screw extruder extruder, ezisetyenziswa kakhulu kumgangatho wangaphakathi okanye ngaphandle, iiparapets, iitreyi, ezifana neemveliso ze-PE&PP extrusion zeplastiki.
