Pom tau siab -kev ntim cov yeeb yaj kiab tsis yog "kev xaiv" nkaus xwb tab sis yog qhov tsim nyog. Nws ua haujlwm raws li cov txheej txheem thev naus laus zis uas ua rau cov khoom ntim tau yooj yim los hloov cov iav fwj thiab cov kaus poom hlau thaum ua kom cov khoom zoo thiab kev nyab xeeb. Qhov no yog lub hauv paus txiav txim siab los ntawm cov khoom siv tshuaj lom neeg ntawm cov ntaub ntawv lawv tus kheej thiab kev lag luam xav tau.
I. Cov Kev Xav Tau Tseem Ceeb tam sim no kom pom pom siab -Kev ntim khoom ntim
Cov ntawv thov tau nthuav dav los ntawm cov khoom noj thiab tshuaj ntim khoom mus rau qib siab -kawg kev lag luam xws li cov roj teeb fais fab, cov khoom siv hluav taws xob, thiab cov ntim tub rog. Tshiab ob -sab pob tshab insulating zaj duab xis tau nkag mus rau hauv cov saw hlau ntawm ATL thiab CATL; cov khoom los ntawm Lucky Huaguang tau txuas ntxiv mus rau cov khoom siv hluav taws xob hloov tau yooj yim thiab ntim tub rog.
Kev kho dua tshiab ntawm cov khoom: hloov mus rau ultra-thinness (tsawg dua lossis sib npaug li 15 μm), ntau- kev sib koom ua haujlwm (kev thaiv + tshuaj tua kab mob + biodegradable), thiab kho kom haum. Cov ntaub ntawv tau ua tiav kev ua tiav hauv kev ua haujlwm siab, tsis muaj nqi, thiab kev phooj ywg ib puag ncig.
Kev xav tau ob zaug hauv kev lag luam zaub mov kom ntev -lub sij hawm freshness preservation + pom kev pom (xws li, ncua lub txee lub neej ntawm cov nqaij txias los ntawm 5 hnub mus rau 21 hnub thaum tso cai rau cov khoom pom); cov kev cai rau pob tshab traceability + siab - thaiv kev tiv thaiv nyob rau hauv kws tshuaj; thiab xav tau kev hloov pauv tau yooj yim + kev tshuaj xyuas qhov muag hauv kev lag luam hluav taws xob.
Txoj cai tsav tsheb: Kev ua raws li GB/T 40266-2021 General Specification for Quality of Oxide Barrier Transparent Plastic Composite Films and Bags for Food Packaging has standardized quality requirements and promoted industrial upgrading.
Kev hloov pauv peev xwm: Kev hloov pauv ntawm cov hnab ntim khoom siv tshuaj txhuas hauv cov zaub mov thiab chaw muag tshuaj yog tsawg dua 15%, nrog kev kwv yees qhov chaw lag luam ntawm 12 billion RMB hauv 3-5 xyoo tom ntej.
II. Disadvantages of Traditional Aluminium Foil Bags
1. Kev ua haujlwm tsis zoo
① Opaque thiab tsis yog - pom: Cov neeg siv khoom tsis tuaj yeem saib xyuas cov khoom siv sab hauv (piv txwv li, kev lwj ntawm cov zaub mov tshiab, kev puas tsuaj rau cov tshuaj), thiab cov khoom lag luam tawm tsam kom nthuav tawm cov khoom zoo, cuam tshuam tsis zoo rau kev txiav txim siab yuav khoom.
② Cov khoom siv tsis zoo, ua rau tawg thiab tsis ua haujlwm: Aluminium ntawv ci yog nkig thiab nyuaj rau laminate. Cracking tus nqi siab tshaj 30% ntawm qhov kub thiab txias hauv qab -10 degree. Thaum lub sij hawm kev thauj mus los, extrusion thiab dabtsi yog khoov tau yooj yim rhuav tshem cov txheej txheem txhuas, ua rau muaj kev cuam tshuam kev ua haujlwm kom tawg (cov pa oxygen thiab dej vapor kis tau nce ntau dua 100 npaug tam sim ntawd).
③ Kev hloov pauv tsis txaus thiab kev txwv tsis pub siv: Cov cua sov me me- qhov rai qhov kub thiab txias (tsuas yog ± 5 degree), nrog rau cov kab jamming tus nqi txog li 15%, tsis ua raws li siab - ceev automated ntau lawm. Nws tsis sib haum nrog microwave cua sov thiab lub tshuab nqus tsev ntim cov tawv nqaij, txwv tsis pub siv cov tais diav npaj thiab npaj tau-- noj zaub mov.
2. Tus nqi thiab ib puag ncig tsis txaus
① Tus nqi siab tag nrho: Cov nqi hluav taws xob tsis zoo ntawm cov khoom siv raw khoom, cov txheej txheem ntau- cov txheej txheem lamination, thiab cov khoom seem ntawm 10%. Txawm hais tias chav tsev tus nqi qis dua siab tshaj -qhov kawg pom siab- lub hnab thaiv, tag nrho cov nqi yog 20% – 30% siab dua vim kev puas tsuaj loj heev (txhua xyoo poob hauv kev lag luam khoom noj los ntawm txhuas ntawv nyiaj lub hnab puas ntau tshaj 10 billion RMB).
② Kev rov ua dua tshiab nyuaj thiab muaj kev pheej hmoo ua raws li ib puag ncig: Aluminium- cov txheej txheem yas sib xyaw yog qhov nyuaj rau kev sib cais, nrog tus nqi rov qab qis dua 5%, tsis ua raws li EU REACH cov cai thiab Tuam Tshoj txoj cai "dual carbon". Hauv qhov sib piv, pom qhov siab - lub hnab thaiv lub hnab siv lub mono-polymer system uas yog 100% recyclable, zam kev nplua ib puag ncig.
③ Kev tsim khoom thiab kev txaus ntshai: Aluminium ntawv ci cia siab rau cov khoom siv raw thiab cuam tshuam los ntawm kev hloov pauv ntawm txhuas txhuas. Txij li xyoo 2025, ntau lub tuam txhab tau pom cov nqi tsim khoom nce 15% -20% vim yog aluminium nqi hikes. Cov ntaub ntawv nyoos rau pom siab - lub hnab thaiv (EVOH, PA, thiab lwm yam) muaj tus kheej hauv tsev - tus nqi txaus ntawm 85%, ua kom cov khoom ruaj khov.
3. Technological Iteration Deficiencies
① Kev txhim kho kev ua tau zoo txwv tsis pub muaj peev xwm: Kev cuam tshuam kev ua tau zoo ntawm cov hnab ntawv aluminium tau mus txog lub fwj thiab tsis tuaj yeem ua tau raws li qhov xav tau ntawm lub zog tshiab thiab hloov pauv hluav taws xob rau ultra-thinness (tsawg dua lossis sib npaug li 20 μm) + siab barrier (OTR Tsawg dua lossis sib npaug ntawm 10⁻³ cc/
.
② Lagging txheej txheem innovation: tsoos txhuas ntawv ci lamination emits volatile organic compounds (VOCs), inconsistent nrog ntsuab ntau lawm tiam sis. Pom tau siab -cov hnab ntim khoom siv eco- cov txheej txheem ua phooj ywg xws li co-extrusion thiab PECVD nrog xoom pa phem emissions.
III. Txheej txheem daws teeb meem rau New High -Barrier Films
Txhawm rau txhawm rau txhim kho qhov kev ua tau zoo ntawm cov pob tshab siab - cov yeeb yaj kiab thaiv (piv rau aluminium ntawv ci), ob qhov kev tso tawm - txheej txheej ua ke yog siv:
1. ALOxPET (Vacuum Aluminum-Coated PET Film) + PVA (Polyvinyl Alcohol) Deposition-Coating ProcessThis composite technology combines physical vapor deposition (PVD) aluminum layer + wet-coated PVA barrier layer to form a sandwich structure: PET substrate – nano-aluminum layer – PVA functional layer. Cov ntsiab lus tseem ceeb yog siv cov pa oxygen zoo ntawm cov txheej txheem txhuas (OTR Tsawg dua lossis sib npaug ntawm 0.1 cc /
thiab lub zog dej vapor barrier ntawm hloov PVA txheej (WVTR Tsawg dua los yog sib npaug rau 0.3 g /
rau synergistic nyhuv. PVA txheej sau micro- pores nyob rau hauv txhuas txheej, daws oxidation thiab kev ua tau zoo degradation ntawm ntshiab txhuas-coated films, ua tau zoo transparency + siab barrier + siab stability.
Barrier mechanism: ntau-txoj kev cuam tshuam. Gas molecules must penetrate the hydrogen-bond network of PVA, the dense aluminum layer, and the PET substrate in sequence, greatly extending diffusion paths. Barrier kev ua tau zoo yog 3-5 npaug siab dua ib qho txhuas los yog PVA txheej, nrog ob qhov kev thaiv qhov tseem ceeb hauv qab 0.05.

2. Nylon (Nqus Silicon Oxide Txheej) + PVA Deposition- Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej SiOₓ (silicon oxide) inorganic barrier txheej yog nqus tsev vacuum- tso rau hauv biaxially oriented nylon (BOPA) zaj duab xis, ua raws li hloov PVA organic siab {{4}. Lub tswv yim tseem ceeb: inorganic compactness (SiOₓ) + organic siab barrier + complementary dej kuj, zoo heev txhim kho oxygen / noo noo / aroma retention, dav siv nyob rau hauv cov zaub mov, tshuaj, thiab hluav taws xob siab -barrier ntim.
(1) Lub Hom Phiaj Txheej Txheem & Cov Ntsiab Lus Lub Hom Phiaj: daws cov teeb meem ntse ntawm cov nylon ntshiab hauv cov av noo siab, dej tsis zoo ntawm PVA ntshiab, thiab brittleness ntawm ntshiab SiOₓ, ua kom pom tseeb, siab barrier, dej tsis kam, flex resistance, thiab ib puag ncig compatibility.
(2) Mechanism of Action
SiOₓ layer: Nano-dense inorganic film providing basic oxygen/moisture barrier, heat and chemical resistance, compensating for PVA's weak moisture barrier. Compactness thiab adhesion nyob ntawm seb lub tshuab nqus tsev, oxygen txaus, tus nqi evaporation, thiab kub substrate.
PVA txheej: Cov qauv crystalline polyhydroxy siab heev xa cov pa oxygen zoo tshaj (zoo dua li EVOH / PVDC nyob rau hauv qhuav qhuav), thaum tiv thaiv thiab ua kom nruj SiOₓ txheej thiab kho qhov tsis xws luag. Dej tsis kam thiab oxygen barrier nyob ntawm seb cov ntsiab lus ntawm cov khoom, hla -linking degree, thiab ziab kub / ceev.
Synergistic nyhuv: SiOₓ muab dej tsis kam; PVA muab oxygen barrier, tsim ib lub cev pob txha tsis muaj zog + organic filling dual - txheej txheej. Kev ua kom zoo ntawm SiOₓ ua kom tsis muaj craters lossis delamination ntawm PVA txheej.
