Pulasitiki yowonongeka ndi mtundu watsopano wazinthu zapulasitiki. Panthawi yomwe chitetezo cha chilengedwe chikukhala chofunikira kwambiri, pulasitiki yowonongeka ndi ECO ndipo ikhoza kukhala m'malo mwa PE / PP m'njira zina. Pali mitundu yambiri ya pulasitiki yowonongeka, yomwe imagwiritsidwa ntchito kwambiri ndi PLA ndi PBAT, maonekedwe a PLA nthawi zambiri amakhala achikasu achikasu, zopangira zimachokera ku zomera monga chimanga, nzimbe etc. . PLA ili ndi kukhazikika kwamafuta abwino, kukana bwino kwa zosungunulira, ndipo imatha kukonzedwa m'njira zambiri, monga extrusion, kupota, kutambasula, jekeseni, kuumba nkhonya. PLA itha kugwiritsidwa ntchito ku: udzu, mabokosi a chakudya, nsalu zosalukidwa, nsalu zamakampani ndi anthu wamba. PBAT ilibe ductility wabwino komanso elongation panthawi yopuma, komanso ...
