Pansi pa pulasitiki ya PE&PP ndi kuti zinthu zopangidwa ndi matabwa ndi pulasitiki zimakhala ndi zida zosiyanasiyana monga kusakaniza, kuyambira kusewera, kutulutsa zinthu, kusakaniza zinthu zopangira mu njira inayake, kupanga tinthu ta matabwa ndi pulasitiki pakati, kenako kufinya zinthu. Ndipo masiku ano, njira ya masitepe awiri imagwiritsidwa ntchito pakadali pano, kugwiritsa ntchito granulation ya extruder ya dual-cone-or two-extruder, kenako zinthu zopangira extruder ya dual-cone kapena single-screw extruder, zomwe zimagwiritsidwa ntchito kwambiri pansi kapena panja, padenga, pa thireyi, monga zinthu zopangira pulasitiki za PE&PP extrusion.
