Nyob rau hauv xyoo tas los no, polypropylene (PP) tau dhau los ua ntau yam khoom siv thiab ruaj khov, tshwj xeeb hauvkev tsim cov hnab woven. Paub txog nws cov khoom ruaj khov thiab lub teeb yuag, PP tau txais kev nyiam los ntawm ntau yam kev lag luam nrog rau kev ua liaj ua teb, kev tsim kho thiab ntim khoom.

Cov khoom siv raw ntawm cov hnab woven feem ntau yog ua los ntawm polypropylene, uas muaj lub zog zoo thiab yoog raws. Tsis tsuas yog cov hnab no tiv taus cov dej noo thiab tshuaj lom neeg, lawv kuj yog UV-resistant, ua rau lawv zoo tagnrho rau kev cia sab nraum zoov thiab kev thauj mus los ntawm cov khoom. UV tsis kam ua kom cov ntsiab lus tiv thaiv los ntawm kev puas tsuaj rau lub hnub ci, ua kom lub neej ntev ntawm cov khoom sab hauv.

Ib qho kev nce qib loj hauv polypropylene thev naus laus zis yog kev txhim kho ntawmbiaxially taw qhia polypropylene (BOPP). Qhov no variant txhim khu lub zog thiab pob tshab ntawm cov khoom, ua rau nws haum rau high-zoo printing thiab branding. BOPP cov yeeb yaj kiab tau siv dav hauv cov ntawv ntim khoom los muab kev tiv thaiv kev ya raws thiab oxygen, uas yog qhov tseem ceeb rau kev khaws cov zaub mov.

Tsis tas li ntawd, raws li ib puag ncig teeb meem hnyav zuj zus tuaj,kev rov ua dua ntawm polypropylenetau txais kev saib xyuas ntxiv. PP yog ib qho ntawm cov khoom siv rov ua dua tshiab, thiab tam sim no cov phiaj xwm tseem tab tom ua los txhawb kom nws sau thiab rov siv dua. Los ntawm kev rov ua dua polypropylene, cov tuam txhab lag luam tuaj yeem txo cov khib nyiab thiab txo lawv cov pa roj carbon monoxide, yog li pab txhawb rau yav tom ntej.

Raws li kev lag luam txuas ntxiv tsim kho tshiab, kev thov rau cov khoom siv zoo, ib puag ncig zoo nkauj xws li polypropylene yuav tsum loj hlob. Nrog nws cov khoom tshwj xeeb thiab cov peev txheej rov ua dua tshiab, polypropylene yuav tsum tau ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov kev ntim khoom ruaj khov, tshwj xeeb tshaj yog nyob rau hauv cov hnab ntim khoom. Qhov kev hloov pauv no tsis tsuas yog muaj txiaj ntsig zoo rau cov tuam txhab tsim khoom, tab sis kuj tseem ua raws li kev siv zog thoob ntiaj teb los txhawb lub luag haujlwm ib puag ncig.
