Filimu ya PVC, yomwe imayimira Polyvinyl Chloride, ndi pulasitiki yolimba komanso yolimba yokhala ndi zinthu zabwino kwambiri zoletsa madzi. Mafilimu a PVC amagwiritsidwa ntchito kwambiri popanga, kumanga, ndi ntchito zapakhomo. M'makampani oyikamo, mafilimu a PVC amagwiritsidwa ntchito kwambiri popanga matumba apulasitiki, mabokosi oyikamo, ndi manja owonekera. Amateteza zinthu ku chinyezi, fumbi, ndi dothi. Kuphatikiza apo, makanema a PVC ali ndi kusinthasintha kwabwino komanso kusinthika, kuwapangitsa kukhala oyenera kupanga zinthu zamapaketi amitundu ndi makulidwe osiyanasiyana. Pa ntchito yomanga, mafilimu a PVC amagwiritsidwa ntchito popanga makatani, makatani, ndi zophimba pansi, chifukwa ndizosavuta kuyeretsa, zolimba, komanso zosagwirizana ndi chinyezi.

Kanema wa PEVA, wachidule wa Polyethylene Vinyl Acetate, ndi pulasitiki wokonda zachilengedwe yemwe amadziwika kuti alibe poizoni. Mafilimu a PEVA ali ndi kachulukidwe kabwino komanso kusinthasintha, kutsutsa bwino kulowa kwa madzi ndi fungo. Chifukwa chake, amagwiritsidwa ntchito kwambiri m'mafakitale am'nyumba ndi m'nyumba. Mafilimu a PEVA amagwiritsidwa ntchito kupanga zovundikira fumbi, makatani osambira, nsalu zapatebulo, ndi zovundikira matiresi, pakati pa zinthu zina zapakhomo. Makanema a PEVA amagwiranso ntchito ngati zida zopangira chakudya chifukwa chosatulutsa mankhwala owopsa, kuonetsetsa chitetezo chawo paumoyo wamunthu.

Zovala zopanda madzi ndi ntchito ina yofunika kwambiri ya mafilimu a PVC ndi PEVA. M’maseŵera akunja ndi m’malo ogwirira ntchito, zovala zosaloŵerera madzi zimagwira ntchito yofunika kwambiri potetezera thupi ku madzi amvula ndi chinyezi. Zovala izi nthawi zambiri zimapangidwa ndi mafilimu opanda madzi kuti awonetsetse kuti ovala amakhala owuma komanso omasuka. Mafilimu a PVC ndi PEVA amagwira ntchito yofunika kwambiri pa zovala zopanda madzi, monga momwe zimatetezera madzi kuti madzi asalowe mu nsalu, kuteteza thupi ku chinyezi. Panthawi imodzimodziyo, mafilimuwa amasonyeza kupuma, kulola kuti chinyezi cha thupi ndi thukuta zisasunthike, motero amakhalabe omasuka kuvala.
