M'moyo, tiwona zizindikiro zambiri zokhudzana ndi kubwezeredwa kwa pulasitiki pamapaketi akunja a mabotolo amadzi amchere apulasitiki, migolo yamafuta apulasitiki, ndi migolo yamadzi yamadzi.Kotero, kodi zizindikiro izi zikutanthawuza chiyani?
Mivi yofananira yanjira ziwiri imayimira kuti zinthu zapulasitiki zopangidwa zimatha kugwiritsidwanso ntchito nthawi zambiri, ndipo magwiridwe antchito amatha kukwaniritsa malamulo oyenera.
Mivi itatu yopita-kumapeto ikuyimira zinthu zapulasitiki zomwe zingagwiritsidwenso ntchito.Akatayidwa, amatha kubwezeretsedwanso ndikusinthidwa kukhala zinthu zatsopano pambuyo pa njira inayake yamankhwala.
Chizindikiro cha zinthu zosagwiritsidwanso ntchito ndi makona atatu okhala ndi mivi iwiri yopita pansi.Zopangidwa ndi pulasitiki zomwe zili ndi chizindikirochi siziloledwa kubwezeredwa ndi kugwiritsidwanso ntchito.
Mivi yozungulira yokhala ndi mabwalo ang'onoang'ono poyambira ndi kumapeto imayimira chizindikiro cha mapulasitiki obwezerezedwanso, omwe ndi thermoplastics omwe amakonzedweratu ndi kuumba fakitale, extrusion, etc., kenako amasinthidwanso m'mafakitale achiwiri opangira zinthu zotsalira.
Mivi yozungulira yomwe imayamba ndi kutha pa imodzi imayimira thermoplastics yopangidwa ndi mapurosesa osakhala apachiyambi kuchokera ku mapulasitiki a mafakitale otayidwa, omwe amangopangidwanso pulasitiki.
Chizindikiro cha pulasitiki yachipatala nthawi zambiri chimakhala ndi chizindikiro, chomwe chimagwiritsidwa ntchito popaka mankhwala.
Mapulasitiki opangira chakudya, zizindikiro za mapulasitiki opangira chakudya, nthawi zambiri amakhala obiriwira, nthawi zambiri amakhala ndi mabwalo ndi makona anayi, okhala ndi chilembo "S" pakati, chomwe chimagwiritsidwa ntchito ponyamula chakudya.
Mvetsetsani zizindikiro zodziwika bwino zamapulasitiki, ndipo m'moyo watsiku ndi tsiku, mutha kugwiritsa ntchito chizindikirochi kuti mudziwe zomwe pulasitiki yomwe imagwiritsidwa ntchito imapangidwa komanso malo omwe ayenera kugwiritsidwa ntchito.
