Nyob rau hauv txawv teb chaws, tshwj xeeb tshaj yog tsim lub teb chaws nyob rau hauv cov teb chaws Europe thiab America, ntau lawm thiab siv polypropylene woven hnab kuj muaj ntau heev. Txawm li cas los xij, tsis zoo li hauv Suav teb, cov teb chaws txawv teb chaws tso siab dua rau kev ua haujlwm ib puag ncig ntawm polypropylene woven hnab. Ntau lub teb chaws thiab cheeb tsam tau tshaj tawm txoj cai nruj ib puag ncig, txwv lossis txwv tsis pub siv cov khoom yas uas tsis yog -degradable.
Yog li ntawd, txawv teb chaws polypropylene woven hnab manufacturers tau mob siab rau lawv tus kheej rau kev tshawb fawb thiab kev loj hlob ntawm biodegradable cov ntaub ntawv. Qee cov ntaub ntawv tshiab biodegradable, xws li polylactic acid (PLA) thiab polyhydroxyalkanoates (PHA), tau siv rau kev tsim cov hnab ntim khoom. Cov ntaub ntawv no tsis yog tsuas yog muaj cov khoom degradation zoo xwb tab sis kuj tuaj yeem hloov cov ntaub ntawv polypropylene ib txwm muaj, yog li txo cov pa phem ib puag ncig.
