Pib nrog Function, Tsis Kho kom zoo nkauj
Aluminium foil ntim hnab tsim yuav tsum pib nrog txoj haujlwm lub pob yuav tsum ua. Ib lub hnab uas tiv thaiv cov dej noo-rhiab hauv hluav taws xob sib dhos thiab ib lub hnab uas ua kom ci kas fes tshiab tuaj yeem sib koom ua ke ntawm cov laminate architecture, tab sis lub hom phiaj tseem ceeb rau kev xa dej vapor, kev xa oxygen, lub zog foob thiab kev sib tsoo yog sib txawv kiag li. Muaj nuj nqi thawj, tsos thib ob.
Cov khoom tiv thaiv: ya raws, oxygen, lub teeb, roj, aroma poob thiab static paug
Cov neeg siv kev paub: qhib quab yuam, tsim kua muag kev taw qhia, resealability, tuav thiab stacking
Kev ua raws cai: zaub mov-thov kev pom zoo rau cov khoom noj khoom haus, kev tswj hluav taws xob hluav taws xob rau hluav taws xob
Ntau lawm: filling kab ceev, foob qhov rai, yob dav thiab luam ntawv sau npe
Tsim nyob ib ncig ntawm plaub pawg no tiv thaiv qhov tsis ua haujlwm feem ntau hauv cov phiaj xwm ntim khoom, uas yog qhov zoo - lub hnab saib uas tsis tuaj yeem khiav ntawm tus neeg siv khoom cov kab ntim khoom lossis qhov ua tsis tiav qhov kev sim ntsuas tom qab peb lub lis piam hauv lub tsev khaws khoom ntub.
Laminate Structure thiab xaiv cov khoom siv
Lub hnab ntawv ua haujlwm yog ib lub laminate, tsis yog ib zaj duab xis. Txhua txheej txhawb nqa ib qho cuab yeej, thiab cov nplaum nplaum tuav cov kev sib dhos ua ke los ntawm kev sib khi thiab kev pabcuam kub.
| Txheej | Yam khoom | Muaj nuj nqi |
|---|---|---|
| Outer, luam tau | PET, BOPP los yog coated ntawv | Sau nto, scuff kuj, nruj, tshuab kev taw qhia stability |
| Barrier tub ntxhais | Aluminium ntawv ci 6 mus rau 12 micrometers | Tsis muaj lub teeb thaiv, tsis tshua muaj dej noo thiab oxygen xa mus, aroma tuav |
| Adhesive | Solvent-raws li, hnyav-dawb lossis extrusion lamination resin | Interlayer bonding thiab tsis kam rau retort los yog lub freezer tej yam kev mob |
| Sealing txheej sab hauv | LDPE, LLDPE lossis CPP | Thaum tshav kub kub sealing rau nws tus kheej, foob lub zog, zaub mov-kev sib cuag |
Ntawv nyiaj thickness yog tus nqi tseem ceeb lever. Hauv qab no kwv yees li cuaj micrometers, pinhole tsim thaum lub sij hawm luam ntawv, lamination thiab tuav tau nce sai, yog li siab - thaiv kev kho mob thiab ntev - txee- lub neej cov khoom noj feem ntau nyob ntawm los yog siab tshaj cuaj micrometers. Tshaj kaum ob micrometers, ntxiv thickness yuav me ntsis ntxiv barrier rau feem ntau cov khoom qhuav thiab feem ntau ntxiv hnyav thiab nqi.
Barrier Performance thiab Test Methods
Barrier thov yuav tsum tau khi rau qhov ntsuas qhov tseem ceeb. Cov dej vapor kis tau tus nqi feem ntau ntsuas nrog cov txheej txheem infrared sensor tau piav qhia hauv ASTM F1249, thiab cov pa oxygen xa mus nrog txoj kev coulometric tau piav qhia hauv ASTM D3985. Cov laminates tiav thiab cov hnab ntim tau raug tshuaj xyuas los ntawm GB / T 10004 rau laminated films thiab hnab ntim khoom. Qhov twg lub hnab kov cov zaub mov, cov txheej yas yuav tsum ua raws li cov khoom noj uas muaj feem xyuam -cov ntaub ntawv xav tau, suav nrog GB 4806.7 rau cov ntaub ntawv yas thiab cov khoom sib cuag nrog cov khoom noj.
Ib qho kev qhia tshwj xeeb qhia txog kev txwv kev sib kis ntawm qhov ntsuas kub thiab qhov txheeb ze ntawm cov av noo, vim tias qhov cuam tshuam qhov tseem ceeb hloov pauv nrog cov kev sim ntsuas. Kev hais tus lej yam tsis muaj xwm txheej ua rau qhov tshwj xeeb tsis raug cai.
Tsim rau sealing, qhib thiab tuav
Foob dav: tsib mus rau kaum millimeters rau peb -sab- foob thiab sawv ntsug- li hnab, dav rau hnyav hnyav
Foob geometry: tiaj tus foob, gusseted hauv qab, doypack puag, fin foob lossis lap foob nyob ntawm cov khoom ntim
Qhib: tsim kua muag ntswj raws li lub tshuab kev taw qhia, laser qhab nia rau kev tswj kua muag tsis muaj thaib
Kaw: nias-rau-kaw zipper, slider zipper lossis degassing valve rau cov khoom tso tawm roj
Kev tuav: kaum lub vojvoog, stacking nruj thiab lub tshuab nqus tsev lossis roj-flush tus cwj pwm ntawm cov kab tsis siv neeg
Static control: dissipative lossis antistatic puab txheej rau cov laug cam, modules thiab cov khoom
Foob qhov rais yog qhov tsim parameter feem ntau underestimated. Lub qhov rooj dav dav tso cai rau cov kab ntim kom tiv taus qhov kub thiab txias; lub qhov rais nqaim tsim cov leakers uas tshwm sim tsuas yog tom qab thauj kev co.
Common Design yuam kev
Chasing cov ntaub ntawv tshiab lossis cov duab thaum tsis quav ntsej txog kev nyab xeeb, kev ntseeg tau thiab yooj yim
Tshaj -txhais cov ntawv tuab yam tsis tau lees paub tias qhov ntsuas qhov ntsuas tau zoo dua
Xaiv ib daim ntawv thov retort lossis lub freezer daim ntawv nplaum uas poob lub zog ntawm kev pabcuam kub
Muab cov kua muag tso rau qhov twg lub kua muag ntws mus rau hauv lub foob thiab yuam tus neeg siv txiav lub hnab qhib
Tsis quav ntsej sau - kab kev muaj tiag: sau qhov hnyav, poob qhov siab thiab foob- puab tsaig geometry
Hla kev thauj khoom simulation, yog li pinholes tsuas yog tshwm sim tom qab cov khoom xa tuaj txog
Cov lus nug nquag
Q: Cov kev lag luam twg siv txhuas ntawv ci ntim hnab?
Khoom noj khoom haus thiab dej haus, tshuaj, khoom siv hluav taws xob rau kev tiv thaiv zoo li qub thiab dej noo- cov hnab pov thawj, tshuaj, thiab khoom siv kho mob. Txhua txoj haujlwm siv qhov sib txawv, kev ua raws cai thiab kev huv huv.
Q: Vim li cas aluminium foil siv los hloov cov yeeb yaj kiab metallized?
Cov ntawv ci txheej txheej thaiv lub teeb kom tag nrho thiab ua kom cov dej noo thiab cov pa xa tawm qis dua li lub tshuab nqus tsev- cov txheej txheem metallized, uas tseem ceeb rau lub neej ntev thiab rau cov dej noo- cov khoom siv tau yooj yim.
Q: Yuav ua li cas tuab aluminium foil txheej?
Rau lub micrometers yog qhov ua tau yam tsawg kawg nkaus rau lub luag haujlwm lub teeb, cuaj micrometers rau qhov dav dav dav, thiab kaum ob micrometers rau kev thov lossis ntxhib- tuav daim ntawv thov. Cov khaubncaws sab nraud povtseg ntxiv tus nqi nrog cov txiaj ntsig tsawg.
Q: Dab tsi ua rau lub hnab haum rau cov khoom siv hluav taws xob?
Ib txheej txheej sab hauv los yog antistatic, tag nrho cov ntawv ci thaiv qhov thaiv, thiab kev tsim kho uas tsis txhob muaj cov khoom siv hluav taws xob thaum lub sij hawm qhib thiab qhib.
Q: Yuav ua li cas sealing zoo xyuas?
Peel lub zog kuaj ntawm cov qauv tsim, zas xim nkag los yog kuaj lub tshuab nqus tsev vacuum ntawm lub hnab, thiab kev sim tawg rau hnyav hnyav, tag nrho ntawm qhov kawg ntawm lub qhov rais sealing.
Q: Cov hnab ntawv puas tuaj yeem siv dua?
Ntau- cov ntaub ntawv laminates nyuaj rau kev sib cais, yog li kev rov ua dua yog nyob ntawm cov khoom siv hauv zos. Txo tag nrho cov txheej suav thiab siv mono-cov ntaub ntawv ntim cov txheej txheem txhim kho kev rov ua dua tshiab yam tsis muaj kev cuam tshuam kev ua haujlwm.
