Dab tsi yog Aluminium Foil Laminated Film?
Aluminium ntawv ci laminated zaj duab xis yog cov khoom ntim ntau txheej uas nyias nyias txheej txheej yog sib txuas ntawm cov yeeb yaj kiab polymer. Ib qho kev tsim kho muaj cov txheej txheem tiv thaiv sab nraud xws li PET lossis BOPP, qhov nruab nrab aluminium ntawv ci thaiv feem ntau yog 6 txog 30 microns tuab, thiab cov cua sov sab hauv- txheej sealable xws li LDPE lossis CPP. Adhesive txheej raws li polyurethane los yog acrylic chemistry khi cov ntaub ntawv ua ke. Qhov tshwm sim sib txuas ua ke lub zog txhua yam ntawm cov polymers nrog rau kev ua haujlwm ntawm cov hlau.
Yuav ua li cas cov txheej txheem lamination cuam tshuam rau Barrier Properties
Qhuav lamination nrog polyurethane adhesives yog dav siv vim nws tsim ib qho kev thaiv thiab txwv kev tsim pinhole. Cov txheej txheem yuav tsum tau tswj nruj nruj kom tsis txhob muaj cov kab nrib pleb hauv cov txheej txheem txhuas, thiab cov nplaum nplaum kom zoo, feem ntau 24 mus rau 48 teev, ua kom muaj zog tshaj plaws. Kev taw qhia ntawm cov txheej txheem polymer thaum lub sij hawm lamination cuam tshuam cov khoom siv ntawm zaj duab xis zaum kawg. Kev kho deg xws li ntshav lossis corona kho ua ntej lamination tuaj yeem txhim kho interlayer adhesion los ntawm qhov muaj txiaj ntsig zoo.
Kev ntsuam xyuas zoo rau Foil Laminates
Kev ntsuas kev sib kis ntawm cov pa ntsuas qhov cuam tshuam rau cov pa oxygen, nrog cov yeeb yaj kiab zoo tshaj plaws mus txog qhov tseem ceeb hauv qab 0.5 cubic centimeters ib square meter ib hnub twg. Kev ntsuas dej vapor kis tau tus nqi txheeb xyuas kev tiv thaiv noo noo, feem ntau qis dua 0.1 gram ib square meter ib hnub twg. Peel lub zog ntsuas ntsuas qhov sib txuas ntawm qhov sib txuas, nrog cov qauv kev lag luam feem ntau xav tau yam tsawg kawg 2 N ib 15 hli, thiab kev ntsuas kub ntawm lub zog foob kom paub meej tias ntim kev ntseeg siab nyob rau hauv thermal stress. Cov kev kuaj ntxiv muaj xws li kev tshawb pom tus pinhole los ntawm cov txheej txheem electrolytic thiab kev txheeb xyuas cov kuab tshuaj seem, feem ntau yuav tsum nyob qis dua 5 mg ib square meter.

Pharmaceutical blister ntim cia siab rau cov ntawv ci laminates rau ya raws - cov tshuaj rhiab heev. Cov khoom ntim aseptic xws li cov hnab ntim khoom siv rov qab siv rau cov txee- cov khoom ruaj khov uas yuav tsum muaj sia nyob siab -kub kom tsis muaj menyuam. High- cov khoom siv hluav taws xob kawg yog lub tshuab nqus tsev vacuum- kaw hauv cov yeeb yaj kiab no rau kev tiv thaiv cov dej noo, thiab cov khoom siv kho mob kom tsis muaj menyuam yuav tsum tau laminates sib xws nrog txoj kev xaiv kom tsis muaj menyuam. Cov kev siv tam sim no suav nrog lithium- ion roj teeb ntim thiab cov txheej txheej txheej rau lub hnub ci hloov tau.
Foil Laminates piv rau Metallized Film
Aluminium ntawv ci muab qhov zoo dua oxygen barrier dua li cov txheej txheem metallized films, nyob rau hauv thaj tsam ntawm 100 mus rau 1000 zaug nyob ntawm kev tsim kho, thiab nws thaiv lub teeb kom tiav. Cov ntawv ci laminates kuj tseem khaws lawv cov teeb meem tom qab flexing, thaum cov yeeb yaj kiab metallized tuaj yeem tsim cov microcracks uas tso pa tawm. Txawm li cas los xij, cov yeeb yaj kiab metallized yog kwv yees li 30 mus rau 50 feem pua sib dua thiab tus nqi ntau dua - siv tau rau cov ntawv thov tsawg dua, thiab tshem tawm siab - cov txheej txheem oxide txheej yog ib qho kev hloov tshiab rau kev siv tshwj xeeb.
Xaiv Cov Lus Cim
Xaiv cov zaj duab xis tsim raws li cov khoom rhiab heev rau oxygen thiab noo noo, sterilization los yog ua noj ua haus txheej txheem, thiab sealing yuav tsum tau ntawm lub ntim kab. Txheeb xyuas cov ntawv nplaum, hom nplaum thiab qhov ntsuas qhov ntsuas qhov cuam tshuam nrog tus neeg xa khoom, thiab thov cov ntaub ntawv xeem rau OTR, WVTR thiab tev lub zog thaum daim ntawv thov raug tswj, xws li tshuaj lossis khoom siv kho mob.
