Tom qab kev sib kis sai sai ntawm cov kab mob txawv teb chaws thaum kawg lub Peb Hlis, qhov kev thov rau kev tiv thaiv cov khoom siv tau nce ntau, uas yog qhov laj thawj tseem ceeb rau kev nce siab ntawm polypropylene. Yog lawm, nws tsis muaj dab tsi ua nrog kev xav lag luam. Nws pom tseeb tias nthwv dej ntawm nce ntxiv yog tsis muaj kev tiv thaiv, thiab nws muaj peev xwm pom tias tom qab tawm," qaib plaub qhov txhia chaw" ;. Ib qho ntxiv, kev hloov pauv ntawm polypropylene nyob rau yav tom ntej sai sai no nce, yog li cov phooj ywg uas ua lag luam polypropylene yuav tsum them sai sai rau cov kev pheej hmoo.
