Ngokwezidingo ezikhethekile zabasebenzisi, singahlinzeka ngomugqa wepayipi odongeni oqinile we-2-layer / 3-layer / 5-layer kanye ne-multilayer. Ama-extruder amaningi angavunyelaniswa, futhi uhlelo lokulawula isisindo lwamamitha amaningi lungakhethwa. ingafakwa phakathi ilawulwe ku-PLC eyinhloko ukuze kuzuzwe ukukhishwa okunembile nokwamanani kwe-extruder ngayinye. Ngokusho kwesikhunta esivunguzayo esinezingqimba eziningi esiklanywe ngezingqimba ezihlukene kanye nezilinganiso zokujiya, ukusatshalaliswa kokugeleza komgodi wesikhunta.iziteshi zinengqondo ukuqinisekisa ukuthi ukushuba kwengqimba yeshubhu kufana futhi umphumela we-plasticization wesendlalelo ngasinye ungcono.
