Malingana ndi zipangizo zosiyanasiyana, filimu yodyera imagawidwa m'magulu awiri:

Mtundu woyamba ndi polyethylene cling film, PE cling film mwachidule.Izi makamaka ntchito ma CD chakudya.Zipatso, ndiwo zamasamba, ndi zakudya zotha kumaliza nthawi zambiri zimayikidwa mufilimu yamtunduwu.

Mtundu wachiwiri ndi PVC cling film mwachidule.Izi zitha kugwiritsidwanso ntchito pakuyika chakudya, koma zimakhudzanso chitetezo chathupi la munthu.

Pali kusiyana pakati pa PE cling film ndi PVC cling film.Mitundu yonse iwiri ya filimu yodyera ndi yopanda mtundu komanso yowonekera.Nthawi zambiri, njira yodziwikiratu yodziwika bwino ndikuzindikiritsa kudzera muzopaka zakunja za filimu yotsatsira.

Maonekedwe a PVC cling filimu amaonekera kwambiri kuposa PE cling filimu, ndipo imatulutsa utsi wakuda pambuyo poyatsa ndi kuyaka popanda kudontha mafuta.M'malo mwake, filimu ya PE itatha kuyatsa ndikuwotchedwa, sidzakhala ndi fungo lachilendo ndipo idzagwetsa mafuta.

Kanema wa PE angagwiritsidwe ntchito potenthetsera ma microwave.Chifukwa cha mawonekedwe osiyanasiyana azinthu zopangira, filimu ya PE cling imalimbana ndi kutentha kwambiri.Mavuni ambiri a microwave ali ndi kusintha kosiyanasiyana kwa mphamvu yamoto.Mukamaphika mu uvuni wa microwave, bola ngati mukugwiritsa ntchito filimu ya PE, simuyenera kuda nkhawa ndi zinthu zovulaza.
