I. Core Zoo ntawm Aluminium Ntawv Nyiaj Hnab
Aluminium foil hnab feem ntau txais yuav peb - txheej txheej txheej txheem ntawm PET / AL (ntshiab aluminium ntawv ci) / PE, thiab tuaj yeem ntxiv txheej PA nylon los txhim kho lub zog. Lawv qhov kev ua tau zoo nyob hauv nruab nrab ntawm 7-12 μm ntshiab aluminium foil txheej, uas ua rau muaj kev cuam tshuam zoo heev.
Kev siv kev lag luam- tus qauv PET/AL/PE test values:
Oxygen Transmission Rate (OTR): Tsawg dua lossis sib npaug li 0.5 cm³ / (m²·24h·0.1MPa) (23℃/ 50%RH)
Dej Vapor Transmission Rate (WVTR): Tsawg dua lossis sib npaug ntawm 0.1 g / (m²·24h) (38℃/ 90% RH)
Rau kev sib piv: cov pa oxygen barrier ntawm metallized hnab (VMPET) yog kwv yees li 1/10 mus rau 1/50 ntawm cov ntshiab txhuas ntawv ci hnab, thiab cov noo noo barrier yog hais txog 1/5 mus rau 1/20.
Hauv cov ntsiab lus yooj yim, txheej aluminium ntawv ci thaiv lub teeb, huab cua, thiab noo noo ib txhij. Cov txiv ntseej tsis tshua muaj rancidity, kas fes hmoov tsis tshua tuaj yeem khaws tawm - flavors, thiab ice crystal sublimation nyob rau hauv khov cw yog txo. Ua ke nrog −18℃khov cia, txee lub neej yog qhov tseem ceeb txuas ntxiv rau cov hnab pob tshab (lub sijhawm ntev nyob ntawm cov ntsiab lus lawv tus kheej, tsis yog ntawm lub ntim nkaus xwb).
Qhov thib ob kom zoo dua yog txo qhov hnyav thiab txo nqi shipping. Sawv ntsug-up aluminium foil pouches tuaj yeem sawv ntawm lawv tus kheej thaum lub gusset hauv qab tau nthuav dav, ua rau lub tsev khaws khoom stacking thiab khw muag khoom txee zoo dua li cov hnab tiaj tus. Tag nrho qhov hnyav yog tshaj 70% qis dua iav rhawv zeb, thiab thaum hla - ciam teb freight raug soj ntsuam los ntawm qhov hnyav (feem ntau rau huab cua / nthuav qhia) lossis los ntawm ntim ( hiav txwv), tus nqi sib txawv yog qhov loj.
Qhov thib peb zoo dua yog ua raws li kev cai thoob ntiaj teb. Cov zaub mov muaj ntawv pov thawj-qib txhuas ntawv ci hnab ua tau raws li FDA, EU 10/2011, thiab GB 4806.9 cov qauv, ua rau kev xa tawm mus rau European, Asmeskas, thiab cov lag luam sab hnub tuaj Asia; whereas uncertified metallized bag is nquag intercepted in random inspections at destination ports.
II. Common Aluminium Foil Bag Hom thiab cov ntsiab lus siv tau
Thaum yuav khoom, ua ntej xaiv lub hnab hom raws li cov ntsiab lus, tom qab ntawd paub meej tias cov khoom siv. Xaiv lub hnab tsis raug cai txwv txawm tias cov khoom siv zoo tshaj plaws.
1. Sawv ntsug-up aluminium foil hnab (nrog zipper)
Haum rau: txiv ntseej, kas fes hmoov, khov- cov khoom noj qhuav, khov dumplings / ua ntej- cov zaub mov noj (cov tub yees tshiab- kaw hom, tsis yog-sterilized), tshuaj yej
Nta: Gusseted hauv qab stands upright, zoo tagnrho rau cov khw muag khoom zaub; zipper qhib thiab kaw ntau zaus; nylon-cov qauv siv zog muaj kev tiv thaiv ntawm −18℃.
Faj seeb: Cov qauv PET / AL / PE yog ntsuas −18℃rau chav tsev kub thiab yuav tsum tsis txhob muab rhaub los yog muab tso rau hauv lub tshuab ua kom tsis muaj menyuam. Rau cov khoom noj uas tsis muaj menyuam tsis taus, siab -kub retort hnab, thiab lwm yam, xaiv tus qauv nrog RCPP sab hauv txheej (sib cais qauv - nug rau cov lus hais).
2. Aluminium foil spout hnab
Haum rau: pob khoom me me ntawm cov roj noj, cov kua ntses, cov kua txiv hmab txiv ntoo, cov txiv hmab txiv ntoo purees
Nta: Tom qab sau, nruj lub hau thiab lub hnab sawv ntsug; lighter dua lub raj mis thiab yooj yim rau ncuav tshaj lub hnab tiaj tus.
Nco tseg: Tsis tas li tsis haum rau siab -kub kom tsis muaj menyuam (tsis yog-retort); tsis txhob boil los yog microwave tom qab sau.
3. Aluminium foil nqus tsev vacuum ca hnab (tsis muaj zipper; peb - sab foob / chaw foob)
Haum rau: ntim khoom siv hluav taws xob, cov khoom siv raw repacking, ntev -cov nqaij khov (−18℃nylon-reinforced version)
Nta: Qhov ntim tsawg tshaj plaws tom qab lub tshuab nqus tsev sealing; hiav txwv qis tshaj - tus nqi thauj khoom.
Tshaj li lub hnab ntim khoom, muaj ob txoj kev xaiv tsim nyog: peb txheej txheem - txheej PET / AL / PE haum rau cov khoom qhuav thiab cov khoom khov; reinforced plaub- txheej PET / AL / PA / PE haum rau cov khoom khov khov nrog cov pob txha, cov npoo ntse, lossis cov tuav tuav, qhov twg PA nylon txheej muab kev tiv thaiv kev sib tsoo.
III. Kev siv thiab kev yuav khoom ceev faj
· Cov lus pom zoo siv
Txias cov zaub mov ua ntej kaw. Cov zaub mov kub tso ncaj qha rau sab hauv ua rau muaj qhov sib xyaw ua kom puas rau cov cua sov sab hauv- sealing ntug thiab yuav ua rau lub foob tsis ua hauj lwm thaum lub sij hawm ntev - khaws cia.
Tsis txhob tso rau hauv qhov cub, microwaves, lossis steamers. Cov khoom no muaj PE sab hauv txheej thiab tsis haum rau siab -kub kom tsis muaj menyuam (tsis yog-retort); Nws pib soften saum 100℃thiab cov txheej txheem sib xyaw yuav sib cais saum 180 degree. Rau kev ntim khoom kom tsis muaj menyuam, xaiv RCPP sab hauv- txheej qauv (cov qauv sib cais).
Tsis txhob ntim cov pob txha ncaj qha lossis cov khoom ntse ntse. Aluminium foil txheej yog yooj yim punctured; rau cov pob txha-nyob rau hauv cov khoom khov, ua qhov tseem ceeb PA- cov qauv ntxiv.
Rau cov ntsiab lus acidic (kua txiv hmab txiv ntoo, ketchup, thiab lwm yam) xav tau ntev - lub sij hawm cia, siv raws li cov ntshiab ntshiab- txhuas hnab ua ke nrog cov zaub mov - qib PE sab hauv txheej; zam lub hnab metallized tsis muaj cim, raws li qhov chaw acidic nce hlau- kev pheej hmoo ntawm kev tsiv teb tsaws.
· Cov lus pom zoo rau kev yuav khoom
Ua ntej kev txiav txim, xav kom lub Hoobkas muab peb cov ntaub ntawv: zaub mov- tiv tauj- cov ntaub ntawv xeem cov ntaub ntawv (cov khoom tsiv teb tsaws), daim ntawv pov thawj ISO22000 lossis HACCP, thiab daim ntawv tshaj tawm EU ua raws (yuav tsum xa tawm mus rau Tebchaws Europe).
Paub meej tias aluminium foil thickness ntawm 7 μm, 9 μm, lossis 12 μm. Cov thickness ntau dua muab kev tiv thaiv zoo dua tab sis tus nqi siab dua; xaiv raws li txee- lub neej xav tau es tsis mus nrhiav thickness blindly.
Kev luam ntawv yuav tsum siv benzene-dawb, ketone- cov inks dawb, uas yog ib qho tseem ceeb rau kev xa tawm mus rau European thiab Asmeskas kev lag luam.
Aluminium foil hnab tsis yog siab - thev naus laus zis, tab sis lawv nyob rau ntawm ob peb tus nqi- kev hloov kho tau zoo hauv cov khoom noj khoom haus hloov pauv tau ntau xyoo dhau los, muab cov nqi qis me me thiab kev ua haujlwm tau zoo.
