1. Cov yam ntxwv zoo
Functional co-extruded zaj duab xis yog ib zaj duab xis sib xyaw nrog ntau txheej txheej thiab co-squeezing tshuab los ua ke ntau lub substrate substrates nrog cov khoom sib txawv. Nws yog tsim nyob rau hauv ib lub sij hawm. Cov kev xav tau sib txawv ntawm cov ntim mos. Cov qauv ntawm kev ua haujlwm co-squeezing membranes yog: PE / TIE / PA / TIE / PE (PA), uas yog nruab nrab thiab nruab nrab ntawm lub zog; PE / TIE / EVOH / TIE / PE, siab blockability, nruab nrab lub zog; PA / EVOH; PA / EVOH; PA / EVOH; PA / EVOH; / PA / TIE / EVA, siab blockability thiab siab zog.
2. Muaj txiaj ntsig zoo
121 ° C), kub tsis kam ({1}} degree C), roj tsis kam; tsis muaj tshuaj lom thiab tsis muaj ntxhiab, ua tau raws li cov qauv huv ntawm cov khoom noj thiab tshuaj ntim khoom; zoo thermal sealing, zoo yooj, zoo pob tshab, thiab lwm yam.
Los ntawm qhov kev xav ntawm kev siv tshuab thiab cov nqi, qhov zoo ntawm kev ua haujlwm co-squeezing films feem ntau suav nrog: tsis txwv los ntawm cov khoom tshwj xeeb, uas tuaj yeem ua tau raws li qhov xav tau ntawm cov ntim sib txawv; ntau theem, qhov hloov tau yooj yim ntawm cov qauv tsim, tus nqi qis dua, xws li nws yuav, raws li tus nqi, raws li tus nqi, tus nqi, raws li tus nqi, raws li tus nqi, tus nqi qis, raws li tus nqi. , tus nqi qis, tus nqi qis, tus nqi qis, tus nqi qis, tus nqi qis, tus nqi qis, tus nqi qis, tus nqi qis, tus nqi qis, tus nqi qis, tus nqi qis dua. , raws li tus nqi, tus nqi qis, tus nqi qis, tus nqi qis, raws li tus nqi qis, tus nqi qis, tus nqi qis, tus nqi qis, tus nqi qis, raws li tus nqi qis, tus nqi qis, raws li tus nqi qis, tus nqi qis, tus nqi qis, tus nqi qis, raws li tus nqi qis, tus nqi qis, tus nqi qis dua. Cov khoom xyaw resin yuav tsum tau txo kom tsawg kawg nkaus thickness, thiab thinnest thickness ntawm ib txheej tuaj yeem ncav cuag 2 mus rau 3 μm, uas tuaj yeem txo cov nqi siv nyiaj kim heev; tsuas yog siv cov txheej txheem tshuab tuaj yeem txo cov nqi tsim khoom zoo.
