Cov yam ntxwv ntawm ntau txheej ntim zaj duab xis yob
High barrier kev ua tau zoo
Kev siv ntau txheej polymers hloov ntawm ib txheej txheej polymerization tuaj yeem txhim kho qhov kev ua tau zoo ntawm cov yeeb yaj kiab nyias, ua kom muaj kev cuam tshuam loj ntawm cov pa oxygen, dej, carbon dioxide, tsw, thiab lwm yam khoom. Tshwj xeeb tshaj yog thaum siv EVOH thiab PVDC ua cov khoom thaiv, lawv cov pa permeability thiab dej vapor permeability yog qhov tsawg heev.
Muaj zog ua haujlwm
Vim qhov kev xaiv dav ntawm ntau txheejzaub mov ntim cov yeeb yaj kiabnyob rau hauv cov ntaub ntawv siv, ntau yam resins tuaj yeem xaiv raws li daim ntawv thov ntawm cov ntaub ntawv siv, ua kom pom tseeb ntawm cov haujlwm sib txawv, txhim kho kev ua haujlwm ntawm co extruded films, xws li roj tsis kam, noo noo tsis kam, siab kub ua hauj, thiab qis. -kub freezing kuj. Yuav siv tau rau lub tshuab nqus tsev ntim, ntim khoom tsis muaj menyuam, thiab ntim khoom ntim.
Tus nqi qis
Piv nrog rau cov iav ntim, aluminium foil ntim, thiab lwm yam ntim yas,yas zaj duab xis yobmuaj tus nqi tseem ceeb hauv kev ua tiav qhov cuam tshuam tib yam. Piv txwv li, kom ua tiav tib yam kev cuam tshuam, xya txheej co extruded zaj duab xis muaj tus nqi ntau dua li tsib txheej.ntim zaj duab xis yob. Vim nws txoj kev ua haujlwm yooj yim, tus nqi ntawm cov khoom ua yeeb yaj kiab tuaj yeem raug txo los ntawm 10-20% piv rau cov yeeb yaj kiab qhuav thiab lwm cov yeeb yaj kiab sib xyaw.
Kev tsim qauv yooj yim
