Raws li peb txhua tus paub, cov hnab ntim khoom tuaj yeem pom txhua qhov chaw hauv peb lub neej txhua hnub, txawm yog cov khw muag khoom, chaw ua haujlwm e-ua lag luam. Ntau yam tsim qauv zoo nkauj, kev siv tau zoo, thiab ntim khoom noj yooj yim tuaj yeem pom txhua qhov chaw. Nws ua raws li kev tiv thaiv lossis teeb meem txheej rau cov khoom noj, zoo li "tiv thaiv" rau cov zaub mov.
Tsis tsuas yog nws tuaj yeem zam kom tsis txhob muaj kev tiv thaiv cov hluav taws xob sab nraud, nws kuj tuaj yeem ua lub luag haujlwm zoo rau cov chaw tsim khoom noj, tua cov noog ntau nrog ib lub pob zeb. Cov. Yog li ntawd, rau ib lub hnab loj, ntim hnab tau dhau los ua ib feem tseem ceeb ntawm ntau yam khoom noj.
Qhov no kuj tseem muaj kev txhawb nqa kev ua lag luam rau lub hnab ntim khoom. Txhawm rau nyob qhov chaw nyob hauv lub hnab ntim khoom noj khoom haus, cov tuam ntxhab txuas ntxiv txhim kho cov ntaub ntawv ntim tau zoo thiab ua kom muaj ntau lub hnab ntim khoom noj. Qhov no tseem tau coj cov kev xaiv rau cov chaw tsim khoom noj kom loj.
Txawm li cas los xij, cov zaub mov sib txawv muaj cov yam ntxwv sib txawv, yog li cov khoom noj sib txawv muaj cov kev tsim muaj sib txawv rau ntim. Piv txwv li, cov tshuaj yej nplooj yog siv rau oxidation, noo noo thiab pwm thiab siv cov tshuab ntim cov pa roj av thiab zoo hygroscopicity. Yog tias cov khoom siv tau raug xaiv tsis tau raws cov yam ntxwv, qhov zoo ntawm cov tshuaj yej nplooj tsis tuaj yeem lav.
Yog li ntawd, ntim khoom yuav tsum tau xaiv cov kev tshawb fawb raws li cov khoom sib txawv ntawm cov zaub mov nws tus kheej. Niaj hnub no, pob mic (Shanghai XiangweI ntim khoom Co., Ltd) sib dhos cov qauv khoom siv ntim khoom noj. Cov khoom noj ntim khoom ntim rau hauv kev ua lag luam tsuas yog suav nrog cov hauv qab no. Nyob rau tib lub sijhawm, cov ntaub ntawv sib txawv yog compounded raws li cov yam ntxwv ntawm cov zaub mov.
Khoom Noj Khoom Haus Ntim Khoom Sau

vAL:
Al yog aluminium ntawv ci cov khoom uas yog silvery dawb, muaj cov khoom siv kub, thiab kub tiv thaiv, roj kuj, thiab cov tshuaj tsw qab ntxeem tau.
vCPP:
CPP zaj duab xis yog cam khwb cia polypropylene zaj duab xis, tseem hu ua ncab polypropylene zaj duab xis. Nws muaj cov yam ntxwv ntawm cov kub ua tsis kam, muaj kev ntsuas kub zoo, cov teeb meem zoo, tsis muaj tshuaj lom thiab paug thiab tsis muaj tseeb.
vPVDC:
PVDC, tseem hu ua polyvinylidene chloride, yog qhov siab tiv thaiv qhov kub xws li nplaim taws tsis kam, corrosion kuj, thiab huab cua zoo.
vVMPET:
VMPET yog polyester aluminium-coated zaj duab xis, uas yog ib qho khoom siv nrog cov khoom muaj zog thiab muaj cov pa hluav taws xob zoo tawm tsam oxygen thiab tsw.
vBOPP:
Bopp (Biaxial Oriented polypropylene) yog lub zog ntim tsis muaj zog thiab tsis muaj ntxhiab, cuam tshuam lub zog, tawv thiab qhov zoo transparency.
vKPET:
KPET yog cov khoom siv nrog cov khoom siv hluav taws xob zoo. PVDC yog coated ntawm tus tsiaj substrate los txhim kho nws cov teeb meem kev tawm tsam tiv thaiv ntau yam roj av, yog li ntsib cov khoom noj muaj txiaj ntsig zoo ntawm cov zaub mov ntim.
Cov khoom noj sib txawv ntim khoom
Retort Hnab
Siv rau ntim cov nqaij, nqaij qaib, thiab lwm yam yuav tsum muaj cov khoom siv tsis muaj zog, thiab tuaj yeem ua kom tsis muaj ntsej muag, tawg, thiab tsis muaj ntxhiab tsw. Feem ntau, cov qauv khoom yuav tsum tau xaiv raws li cov khoom tshwj xeeb. Piv txwv, cov hnab pob tshab tuaj yeem siv rau ua noj, thiab txhuas ntawv ci hnab yog qhov tsim nyog rau kev ua kub kub. Cov qauv khoom siv tshwj xeeb ua ke:
Dawb vogLaminated qauv:
BOPA / CPP, PET / CP / CP / BOPA / CPP, BOPA / CPP, PET / PVDC / CPP, GL-Tsiaj / BOPA / CPP
Txhuas Ntawv Nyiajlaminated khoom siv qauv:
PET / AL / CPP, PA / AL / CPP, PET / PA / PA / CPP, PUA / PA / CPP
Puffed Khoom Noj Khoom Haus Khoom Noj Khoom Noj Khoom Noj Ntim Hnab
Feem ntau, cov khoom noj uas tsis muaj puffed tsuas yog ua tau raws cov yam ntxwv ntawm cov pa oxygen, cov tshuaj tsw qab, cov tshuaj tsw qab, muaj cov xim kaj, ci, thiab tus nqi qis. Kev siv cov qauv khoom siv BOPP / VMCPP cov qauv ua ke tuaj yeem ua tau raws li cov kev xav tau ntim ntawm cov khoom noj txom ncauj khoom txom ncauj.
Biscuit ntim hnab
Yog tias nws yog siv rau ntim cov khoom noj xws li biscuits, lub teeb zoo-thaiv, siab lub zog, tsis muaj qab hau. Yog li ntawd, peb xaiv cov qauv khoom ua ke xws li BOPP / Expe / VMPET / Expe / S-CPP.
Mis Lim Ntim Hnab
Nws yog siv rau cov mis lim. Lub hnab ntim khoom yuav tsum tau ua kom tau raws li qhov xav tau ntawm lub neej ntev ntev, tshuaj tsw qab, tiv taus oxidation thiab tsis zoo rau noo noo, thiab kev tawm tsam rau noo noo noo thiab agglomeration. Rau cov mis hmoov ntim, bopp / VMPET / S-PE Cov qauv khoom siv tau raug xaiv.
Rau cov hnab ntim tshuaj yej ntim, txhawm rau kom ntseeg tau tias cov tshuaj yej nplooj tsis pom, xaiv Bopp / al / PE, PE, KPET / PE
Cov qauv khoom siv tau zoo dua tiv thaiv cov protein zoo dua los tiv thaiv cov protein, chlorophyll, catechin, thiab vitamin C muaj nyob hauv cov tshuaj yej ntsuab los ntawm kev ua oxidized.
Qhov saum toj no yog qee cov khoom noj ntim khoom noj uas ntim cov khoom ntim uas ntim tau ua tiav rau koj thiab yuav ua li cas los sib xyaw cov khoom sib txawv. Kuv vam tias nws yuav pab tau koj :)
