Pali mitundu itatu ikuluikulu yazosawonongekazipangizo za polima.Chimodzi ndi zinthu za polima zopangidwa ndi tizilombo tating'onoting'ono, zomwe makamaka zimapezedwa ndi fermentation ya tizilombo, ndipo choyimira kwambiri ndi polyhydroxybutyrate, yomwe ili ndi katundu wabwino wa biodegradation.Komabe, ndalama zopangira ndi kupanga zinthu zoterezi ndizokwera kwambiri, ndipo sizigwiritsidwa ntchito kawirikawiri popanga zinthu zinazake.Chachiwiri ndi zinthu zopangidwa ndi polima.Pakadali pano, zida zomwe zimagwiritsidwa ntchito kwambiri polima pamsika waku China ndi mowa wa polyvinyl ndi polycaprolactone.Pakati pawo, polycaprolactone imagwiritsidwa ntchito kwambiri popanga zakudya.Chachitatu ndi zinthu zachilengedwe za polima.Zida zachilengedwe zodziwika bwino za polima zimaphatikizapo mapadi, wowuma, mapuloteni, ndi chitosan ngati zida zamatrix.Pambuyo pakugwiritsa ntchito kwakanthawi, zinthu zachilengedwe za polima zimatha kuonongeka bwino ndipo sizikhudza chilengedwe chakunja.kuipitsa kulikonse.
Zosawonongekama polima ndi chimodzi mwazinthu zatsopano kwambiri pantchito yolongedza.Ma polima a biodegradable ali ndi zabwino zakemagwero ambiri, kubwezeretsedwanso, kuteteza chilengedwe komanso kusaipitsa,koma ma biopolymers ali ndi malire ena pokhudzana ndi kutentha kwa mpweya, mpweya ndi mpweya wa madzi, mtengo ndi makina.Chifukwa chake, kafukufuku wamapaketiwa akuyenera kuyamikiridwa kwambiri kuti apititse patsogolo moyo wa alumali, zakudya zopatsa thanzi komanso chitetezo cha tizilombo toyambitsa matenda.
Zotsatira zake, makampani ochulukirachulukira ayamba kupanga zoyikapo zopangidwa ndi zinthu zosawonongeka, zomwe zimayenderana ndi zomwe zikuchitika komanso kusintha misika yatsopano.
