Cov ntaub ntawv raw ntawm cov ntaub tsis-woven yog polypropylene, thiab cov khoom siv raw ntawm lub hnab yas yog polyethylene. Txawm hais tias ob qho tshuaj ntawd muaj cov npe zoo sib xws, cov qauv hauv tshuaj lom neeg yuav sib txawv heev. Cov tshuaj lom neeg molecular qauv ntawm polyethylene muaj qhov kev txiav txim siab ruaj khov thiab yog qhov nyuaj heev rau kev cuam tshuam. Yog li, nws siv sijhawm 300 xyoo rau lub hnab yas kom decomposed. Tus qauv tshuaj lom neeg ntawm polypropylene tsis muaj zog, thiab cov saw hlau molecular yuav yooj yim tawg, yog li nws tuaj yeem ua kom zoo. Thiab nyob rau hauv daim ntawv tsis muaj tshuaj lom rau hauv lub voj voos ib puag ncig tom ntej, ib lub hnab ntim tsis-woven yuav ua tau tiav txhua yam tsis pub dhau 90 hnub.
