Zvakajairwa kufefeterwa firimu kugadzirisa kana flat extrusion processing inowanzo shandiswa muPE firimu kugadzirisa. Iyo yakawanda yePEs inoshandiswa kumafirimu; sarudzo dzinosanganisira mutsara wakaderera density PE (LLDPE) kana general-chinangwa chakaderera density PE (LDPE). Kana kutambanudza kukuru uye hunhu hwakanakisa hwekuvharira hunodiwa, HDPE bhaisikopo mamakisi anowanzo shandiswa. Semuenzaniso, HDPE firimu rinowanzo shandiswa mumabhegi esupamaketi, kurongedza chikafu, uye mabhegi echigadzirwa.
