Txawm hais tias kev txhim kho thev naus laus zis, qhov tseem ceeb cuam tshuam rau qhov zoo ntawm high-barrier stretch film kom deb li deb yog cov khoom siv thiab cov txheej txheem ntawm high-barrier stretch film, yog vim li cas vim li cas high-barrier stretch film yog superior yog tias nws muaj cov txheej txheem hauv qab no:
Txhawm rau kom tau txais txiaj ntsig zoo ntawm cov khoom ntawm ntau yam polymers tib lub sijhawm, cov txheej txheem ntau txheej feem ntau siv rau hauv ntim. Cov txheej txheem txheej txheej txheej txheej txheej txheej zaj duab xis yog tsim cov qauv duab los ntawm ntau hom polymers sib txawv hauv tib txoj kev. Txhua lub polymer tuaj yeem siv tshuaj lom neeg thiab lub cev Qhov zoo ntawm kev ua tau zoo los ntawm ib qho, uas daws cov kev xav tau tshwj xeeb ntawm cov khoom ntim hauv cov khoom noj, tshuaj thiab lwm yam lag luam, tshwj xeeb tshaj yog cov khoom siv yeeb yaj kiab barrier rau kev kawm PA.EVOH.
Barrier stretch film ntim siv lub cev txoj kev thiab txais kev lees paub thoob ntiaj teb cov ntaub ntawv tiv thaiv ib puag ncig rau tus kheej tapping. Nws txawv ntawm feem ntau ntawm cov khoom ntim tam sim no. Nws tsis siv cov nplaum nplaum, tsis muaj cov hlau hnyav, thiab tsis muaj teeb meem residual solvent. Nws yog ib puag ncig phooj ywg thiab khoom noj khoom haus nyab xeeb. Pob.
