Vim li cas Aluminium Foil Ntim Peforms txawv ntawm daim ntawv thov
Aluminium ntawv nyiaj tsis tshua muaj siv ib leeg hauv ntim. Nws yog txheej txheej thaiv sab hauv lub laminate uas nws qhov kev ua tau zoo yog txiav txim siab los ntawm yuav ua li cas lub hauv paus, kev ua haujlwm thiab cov cua sov- cov khaubncaws sab nraud povtseg tau sib xyaw ua ke thiab yuav ua li cas txhua txheej ua raws li cov khoom tiv thaiv. Kev nkag siab txog cov qauv piav qhia vim li cas tib lub hauv paus ntawv ci tuaj yeem muag rau hauv lub pob kas fes, lub hnab ntim rov qab thiab lub hlwv tshuaj uas muaj qhov sib txawv kiag li.
| Txheej | Yam khoom | Muaj nuj nqi hauv laminate |
|---|---|---|
| Base los yog txheej txheej | BOPET, BOPP, ntawv, board | Sau nto, mechanical tiv thaiv, ya raws thaiv thiab nruj |
| Functional los yog barrier txheej | Aluminium ntawv ci, metallized zaj duab xis, oxide-coated zaj duab xis | Oxygen, noo noo, lub teeb thiab aroma barrier; khoom compatibility |
| Kub- txheej txheej | LDPE, LLDPE, CPP, ionomer | Kev sib cuag cov khoom ncaj qha, sealability, foob lub zog thiab tev tus cwj pwm |
Composite thev naus laus zis, tsis yog cov ntawv ci ib leeg, teeb tsa qhov teeb meem tiag tiag ntawm pob. Lub laminate nrog 9 micrometer foil core thiab lub suab nplaum nplaum tuaj yeem ua tau zoo dua cov qauv uas hnyav dua, kev xaiv cov nplaum los yog cov khoom sib khi tau cuam tshuam rau txheej txheej txheej.
Barrier Performance thiab Foil Gauge Xaiv
Rolled aluminium foil khaws nws txoj haujlwm ua haujlwm vim tias nws tsis tuaj yeem ua rau cov pa roj thiab ya raws thaum nws txuas ntxiv. Cov ntawv ci ntawm li 20 micrometers thiab siab dua yog qhov zoo pinhole-dawb, thaum cov ntsuas nyias ntawm 6.5 mus rau 12 micrometers cia siab rau cov txheej puag ncig los txuas rau micro- tawg ua los ntawm flexing thiab converting. Cov ntawv ci kuj yog qhov tsis zoo, uas tiv thaiv lub teeb- cov khoom noj khoom haus, tshuaj thiab cov khoom lag luam, thiab nws tuav nws cov khoom thaiv kev hla ntau qhov kub thiab txias, suav nrog kev rov ua dua ntawm 121 degrees Celsius.
Zoo xoom dej vapor thiab oxygen kis tau tus mob thaum lub foil txheej nyob twj ywm unbreaked
Tag nrho lub teeb thaiv, tiv thaiv cov vitamins, rog thiab cov khoom xyaw nquag
Aroma thiab tsw retention uas ua rau cov tshuaj volatile hauv pob
Mechanical stability los ntawm kev sib sib zog nqus khov los ntawm retort sterilization
Sib tw Barrier Technologies
Metallized zaj duab xis tau nthuav tawm kev lag luam hauv kev lag luam ntim khoom hauv xyoo 1960 thiab nthuav dav sai hauv North America thiab Europe thaum xyoo 1980s ua ntej kis mus rau Tuam Tshoj hauv xyoo 1990. Nws nqa lub nqus tsev vacuum-txheej txhuas txheej tsuas yog ob peb puas angstroms tuab, uas muab cov khoom zoo nkauj zoo nkauj zoo nkauj thiab muaj txiaj ntsig zoo ntawm cov khoom siv qis dua. Nws tau hloov pauv cov ntawv ci hauv daim ntawv lo, cov ntaub qhwv sab nraud thiab qee lub luag haujlwm ntawm lub ntim hloov tau yooj yim, thiab ntau- txheej txheej lamination tshuab tau txuas ntxiv mus.
Ob lub thev naus laus zis ntxiv rau cov ntawv ci hauv cov niches tshwj xeeb. Oxide-coated films, tsim los ntawm kev tso ib txheej silicon oxide nyias rau ntawm cov yas substrate, ua ke nrog kev thaiv siab nrog pob tshab thiab microwave kam rau ua, uas haum rau siab - kub ua noj- nyob rau hauv thiab microwaveable zaub mov ntim, dej haus thiab roj noj; lawv cov kev txwv tseem yog tus nqi tsim khoom siab thiab loj - txheej txheej txheej txheej uas tseem tab tom loj hlob. Nanostructured barrier cov ntaub ntawv, dav piav raws li qhov zoo tshaj plaws ntim tshuab ntawm lub xyoo pua no, nyob twj ywm loj nyob rau theem kev loj hlob nrog ob peb daim ntawv thov kev lag luam.
| Daim ntawv thov | Hom ntawv ci gauge | Daim ntawv qauv |
|---|---|---|
| Tsev thiab catering foil | 10 mus rau 20 micrometers | Ib leeg ply, tsis muaj laminate |
| Khoom txom ncauj thiab confectionery qhwv | 6.5 txog 12 micrometers | Ntawv nyiaj sib txuas rau BOPP lossis ntawv |
| Kas fes, tshuaj yej thiab qhuav mix | 9 mus rau 12 micrometers | Ntawv nyiaj ntxiv sealant, siab noo noo barrier phiaj |
| Retort thiab sterilization pouches | 7 mus rau 12 micrometers | PET, ntawv ci thiab CPP qauv, cua sov- tiv taus foob |
| Aseptic cartons | 6.5 txog 9 micrometers | Cov ntawv nplaum txuas rau lub rooj tsavxwm, nruj flex- tswj kev tawg |
| Pharmaceutical hlwv | 20 mus rau 25 micrometers | Cov ntawv tawv tawv lossis txias - qauv tsim |
Cov khoom siv foil yog ib txwm muab rau ASTM B479, EN 546 lossis GB / T 3198, nrog cov ntawv ci txhais tau tias yog cov khoom siv aluminium dov ntawm 0.2 hli lossis tsawg dua hauv cov tuab. Specification yuav tsum tau kho pinhole suav, wettability, deg huv si thiab interlayer adhesion, vim hais tias cov variables txiav txim siab tiag pob kev ua tau zoo nyob deb tshaj nominal gauge ib leeg.
Sustainability thiab Recycling Pressure
Kev cai ntim khoom tsis tu ncua thawb cov hloov pauv mus rau cov qauv nyias nyias thiab yooj yim sib cais thaum kawg ntawm lub neej. Cov ntawv ci laminates tuaj yeem txo qis los ntawm kev txhim kho cov nplaum nplaum thiab sealant, thiab mono- cov ntaub ntawv los yog ntawv ci- ntxiv rau- cov qauv polyolefin yooj yim rau rov zoo dua li kev sib xyaw ua ke ntau -polymer tsim. Siv cov txhuas tseem hais kom cov nqi rov ua dua txuas nrog nws cov ntsiab lus hlau, thiab cov khoom siv txhuas siv tau tsuas yog ib feem me me ntawm lub zog uas xav tau rau kev tsim khoom, uas ntxiv dag zog rau cov ntaub ntawv khaws cov ntawv ci hauv cov qauv uas tuaj yeem sau thiab txheeb.
Kev txhim kho Outlook
Aluminium-raws li kev sib xyaw ua ke yuav tsum ua kom tshem tawm ib qho khoom siv xws li cov yas thiab cov ntawv vim tias lawv muab cov kev cuam tshuam nrog kev sib tw nqi. Kev ntim khoom yooj yim kuj tseem hloov cov ntim khoom nruj thiab ib nrab- cov thawv ntim khoom nruj thoob plaws cov khoom lag luam dav dav, los ntawm kev muab tshuaj, thaiv, granular thiab hmoov khoom rau cov kua, semi-kua thiab roj- muaj cov khoom, thiab los ntawm cov khoom siv rau kev tiv thaiv thiab chaw ua haujlwm. Tuam Tshoj twb tau txais ib tug loj heev saj zawg zog ntim converter puag nrog composite zaj duab xis muaj peev xwm zoo tshaj ib lab tonnes ib xyoo, thiab txuas ntxiv kev lag luam cov ntsiab lus rau lub teb chaws ua lub ntiaj teb no tus loj tshaj plaws ntim kev lag luam. Cov ntaub ntawv tswv yim tshiab yuav siv ib feem ntawm cov niches tshwj xeeb, tab sis rau lub sij hawm nruab nrab aluminium -raws li laminates khaws cov nqi meej thiab kev ua tau zoo.
Cov lus nug nquag
Q: Dab tsi yog qhov tsawg kawg nkaus foil thickness uas tseem thaiv cov pa oxygen thiab noo noo tag?
Ib txheej ntawv ci txuas ntxiv ntawm txog 20 micrometers lossis ntau dua tuaj yeem kho raws li tag nrho cov teeb meem. Gauges ntawm 6.5 mus rau 12 micrometers yog ib qho yooj yim laminates tab sis nyob ntawm lub hauv paus thiab sealant txheej los npog pinholes thiab flex tawg.
Q: Puas tuaj yeem ntim aluminium ntawv ci mus rau hauv lub microwave?
Tsis ncaj. Hlau qhia txog lub zog microwave, yog li cov zaub mov hauv pob ntawv tsis tuaj yeem ua tiav raws li nws sawv. Oxide-coated pob tshab zaj duab xis tau tsim tshwj xeeb rau microwave thiab siab - daim ntawv thov ua noj kub qhov twg cov ntawv ci tsis haum.
Q: Puas yuav metallized zaj duab xis hloov aluminium ntawv ci?
Nws yuav siv, thiab twb tau noj, ib feem ntawm daim ntawv lo thiab cov ntaub ntawv qhwv sab nrauv ntawm tus nqi. Nws tsis yog ib qho kev hloov pauv tag nrho uas yuav tsum muaj cov khoom siv roj tiag tiag, kev ua kom pom tseeb lossis kev tawm tsam, yog li ntawv ci khaws nws txoj hauj lwm nyob rau hauv siab - thaiv thiab ntev - txee- lub neej packs.
Q: Kuv yuav txiav txim siab li cas ntawm 7, 9 thiab 12 micrometer foil?
Pib los ntawm txee- lub hom phiaj lub neej thiab kev tsim txom lub pob yuav pom. Lub neej txee ntev dua, kev ua haujlwm rov qab thiab ua haujlwm hnyav txhua qhov thawb mus rau cov ntawv ci hnyav dua; luv-cov khoom qhuav hauv lub neej hauv lub qhov dej- txhawb laminate tuaj yeem khiav ntawm qhov sib dua.
Q: Puas yog laminate nplaum tseem ceeb npaum li cov ntawv ci?
Yog lawm. Adhesive xaiv tswj daim ntawv cog lus lub zog, kev laus tus cwj pwm thiab seb cov ntawv ci nyob twj ywm tsis tu ncua los ntawm kev hloov pauv thiab flexing. Cov adhesion tsis zoo los yog ib qho chaw tsis sib haum xeeb yuav ua rau lub qhov thaiv ntawm cov ntawv ci tsis txaus.
Q: Dab tsi cov qauv npog ntim ntawv?
Aluminium ntawv nyiaj rau cov khoom ntim tau yooj yim yog ib txwm teev rau ASTM B479, EN 546 lossis GB / T 3198, ntxiv los ntawm cov neeg siv khoom xav tau rau pinhole suav, wettability, thickness kam rau ua thiab kev huv huv.
