PBAT - yog ib tug copolymer ntawm aliphatic (butanediol adipate) thiab aromatic (butanediol terephthalate)
Nws muaj zoo heev degradability thiab zoo mechanical zog
PLA - polylactic acid, yog tsim los ntawm cov hmoov txhuv nplej siab raw cov ntaub ntawv thov los ntawm cov khoom siv cog qoob loo (xws li pob kws, cassava, thiab lwm yam). Nws muaj biodegradability zoo, thiab tuaj yeem degraded tag nrho los ntawm cov kab mob hauv cov kab mob hauv cov xwm txheej tshwj xeeb tom qab siv, thiab thaum kawg tsim. carbon dioxide thiab dej.
Ob qho no tam sim no nyob rau hauv qhov tseeb ntawm biodegradable hnab yas
