Zovala za pulasitiki ndizofala pazakudya za tsiku ndi tsiku. Chifukwa cha kupepuka kwawo, kulimba, komanso kukwanitsa kugula, amagwiritsidwa ntchito kwambiri m'nyumba, m'malesitilanti, ndi panja. Komabe, ogula ambiri nthawi zambiri amanyalanyaza kufunikira kosankha ndi kugwiritsa ntchito mbale zapulasitiki kuti azitha kuchita bwino komanso chitetezo.
Choyamba, posankha mbale zapulasitiki, tcherani khutu pazinthuzo. Zida zamapulasitiki zodziwika bwino zimaphatikizapo polypropylene (PP), polyethylene (PE), ndi polystyrene (PS). PP imakhala yabwino kukana kutentha, kupirira kutentha pafupifupi madigiri 120, kupangitsa kuti ikhale yoyenera kutentha kwa microwave. PS, komabe, (monga mabokosi a foam lunch) simamva kutentha-ndipo imatha kutulutsa zinthu zoipa ikatenthedwa, choncho sayenera kugwiritsidwa ntchito kusunga chakudya chotentha. Kuphatikiza apo, {{6}mapuleti apulasitiki apamwamba kwambiri amakhala osalala komanso osanunkhiza, pomwe zinthu zotsika zimatha kukhala ndi zopangira pulasitiki kapena zitsulo zolemera kwambiri, zomwe zimatha kuwononga thanzi pakapita nthawi. Choncho, tikulimbikitsidwa kuika patsogolo zinthu zotchedwa "chakudya kalasi" kapena "microwave otetezeka."
Kukana kutentha kwa mbale zapulasitiki ndikofunikira pakagwiritsidwe ntchito. Ngakhale mbale za PP zosamva kutentha siziyenera kuyatsidwa ndi moto kapena kuziyika mu uvuni wotentha kwambiri-kwa nthawi yaitali. Poyeretsa, pewani kukanda ndi zinthu zolimba monga ubweya wachitsulo, chifukwa izi zingawononge mawonekedwe a pamwamba ndi kulimbikitsa kukula kwa bakiteriya. Mukayika ma microwaving, tikulimbikitsidwa kuphimba ndi chopukutira chapepala chopumira kuti chakudya chitha kufalikira. Komanso, yang'anirani nthawi yotentha kuti mupewe kutenthedwa ndi kusinthika.
Ma mbale apulasitiki otayidwa ndi osavuta, koma kudalira kwambiri iwo kumatha kukulitsa zolemetsa zachilengedwe. Ngati n'kotheka, mbale zapulasitiki zogwiritsidwanso ntchito zimakhala zotetezeka ku chilengedwe. Mukatha kugwiritsa ntchito, ziyenera kutsukidwa nthawi yomweyo ndikuwumitsa bwino. Sungani pamalo abwino-opanda mpweya, wouma kuti musamakhale ndi chinyezi chomwe chingapangitse nkhungu kukula.
Mwachidule, mbale zapulasitiki ziyenera kusankhidwa ndikugwiritsidwa ntchito moyenera malinga ndi zinthu zawo zakuthupi, kuchepetsa kukhudzidwa kwa chilengedwe. Makhalidwe ogwiritsira ntchito moyenera amatha kupangitsa kukhala kosavuta komanso kulinganiza malingaliro aumoyo ndi chilengedwe.
