Zaj duab xis OPP yog ib hom zaj duab xis polypropylene, uas hu ua co-extruded oriented polypropylene (OPP) zaj duab xis vim tias cov txheej txheem ntau lawm yog ntau txheej extrusion. Yog tias muaj cov txheej txheem ncab ob-directional hauv kev ua tiav, nws hu ua bi-directional oriented polypropylene zaj duab xis (BOPP). Qhov thib ob hu ua cast polypropylene zaj duab xis (CPP) piv rau cov txheej txheem co-extrusion. Peb zaj duab xis sib txawv hauv lawv cov khoom thiab kev siv.
I. Cov kev siv tseem ceeb ntawm OPP zaj duab xis
OPP: oriented polypropylene (zaj duab xis), oriented polypropylene, yog ib hom polypropylene.
Cov khoom tseem ceeb ua los ntawm OPP:
1, daim kab xev OPP: zaj duab xis polypropylene ua ib lub substrate, nrog lub zog tensile siab, lub teeb yuag, tsis muaj tshuaj lom, tsis muaj saj, tus phooj ywg ib puag ncig, ntau yam kev siv thiab lwm yam zoo
2, OPP daim ntawv lo:Rau kev ua lag luam yog cov khoom siv niaj hnub uas muaj ntau thiab sib xyaw ua ke, qhov tsos yog txhua yam, thawj qhov kev xav txiav txim siab tus cwj pwm yuav khoom ntawm tus neeg siv khoom. Tshuaj zawv plaub hau, tshuaj da dej, tshuaj ntxuav tes thiab lwm yam khoom siv hauv chav dej thiab chav ua noj sov thiab noo noo, qhov yuav tsum tau ua ntawm daim ntawv lo kom tiv taus cov dej noo thiab tsis poob, thiab nws qhov kev tiv thaiv rau extrusion yuav tsum tau phim nrog lub raj mis, thaum lub raj mis pob tshab rau qhov pob tshab ntawm cov nplaum thiab cov ntawv lo muab tso rau pem hauv ntej qhov yuav tsum tau ua hnyav.
Cov ntawv OPP piv rau cov ntawv lo, nrog rau kev pom tseeb, lub zog siab, noo noo, tsis yooj yim poob thiab lwm yam zoo, txawm hais tias tus nqi nce ntxiv, tab sis tuaj yeem tau txais kev tso saib thiab siv cov txiaj ntsig zoo heev. Tab sis tuaj yeem tau txais kev tso saib thiab siv cov txiaj ntsig zoo heev. Nrog rau kev txhim kho ntawm kev siv tshuab luam ntawv hauv tsev, kev siv tshuab txheej, kev tsim cov ntawv nplaum zaj duab xis thiab cov ntawv luam ntawv zaj duab xis tsis yog teeb meem lawm, nws tuaj yeem kwv yees tau tias kev siv cov ntawv OPP hauv tsev yuav txuas ntxiv mus ntxiv.
Vim tias daim ntawv lo nws tus kheej yog PP, tuaj yeem sib xyaw zoo nrog PP / PE lub thawv nto, kev xyaum tau ua pov thawj tias OPP zaj duab xis tam sim no yog cov khoom siv zoo tshaj plaws rau kev sau ntawv hauv pwm. Kev lag luam khoom noj khoom haus thiab tshuaj lom neeg txhua hnub hauv Tebchaws Europe tau muaj ntau daim ntawv thov, thiab maj mam kis mus rau hauv tsev, muaj ntau tus neeg siv pib them sai sai rau lossis siv cov txheej txheem sau ntawv hauv pwm.
Qhov thib ob, lub hom phiaj tseem ceeb ntawm BOPP zaj duab xis
BOPP: Zaj duab xis polypropylene biaxially oriented, kuj yog ib hom polypropylene.
Cov yeeb yaj kiab BOPP feem ntau siv muaj xws li:
● zaj duab xis polypropylene dav dav bi-oriented,
● zaj duab xis polypropylene bi-oriented uas kaw cua sov,
● zaj duab xis ntim luam yeeb,
● zaj duab xis polypropylene pearlescent bi-oriented,
● zaj duab xis polypropylene metallized bi-oriented,
● zaj duab xis matte thiab lwm yam.
Cov kev siv tseem ceeb ntawm ntau yam yeeb yaj kiab yog raws li nram no:
1, Zaj duab xis BOPP ib txwm muaj
Feem ntau siv rau kev luam ntawv, ua lub hnab, ua daim kab xev nplaum thiab sib xyaw nrog lwm cov substrates.
2, BOPP zaj duab xis kub kaw
Feem ntau yog siv rau kev luam ntawv, ua lub hnab thiab lwm yam.
3, BOPP luam yeeb ntim zaj duab xis
Siv: Siv rau kev ntim cov luam yeeb ceev ceev.
4, BOPP zaj duab xis pearlized
Siv rau cov khoom noj thiab cov khoom siv hauv tsev tom qab luam ntawv.
5, BOPP Metallized Zaj duab xis
Siv ua lub tshuab nqus tsev metallization, hluav taws xob, tiv thaiv kev cuav substrate, ntim khoom noj.
6, BOPP zaj duab xis matte
Siv rau xab npum, khoom noj, luam yeeb, tshuaj pleev ib ce, tshuaj thiab lwm yam thawv ntim khoom.
7, BOPP zaj duab xis tiv thaiv huab cua
Siv rau ntim cov zaub, txiv hmab txiv ntoo, sushi, paj thiab lwm yam.
BOPP zaj duab xis yog ib qho tseem ceeb heev rau cov ntaub ntawv ntim khoom yooj ywm, siv dav.
BOPP zaj duab xis tsis muaj xim, tsis muaj ntxhiab, tsis muaj saj, tsis muaj tshuaj lom, thiab muaj lub zog tensile siab, lub zog cuam tshuam, kev nruj, kev tawv thiab kev pom tseeb zoo.
Lub zog ntawm zaj duab xis BOPP yog tsawg, yog li ntawd, ua ntej kho corona, nws yuav tsum tau nplaum los yog luam ntawv. Txawm li cas los xij, zaj duab xis BOPP tom qab kho corona muaj kev hloov pauv zoo rau kev luam ntawv, thiab nws tuaj yeem luam xim thiab zoo nkauj, yog li ntawd feem ntau siv ua cov khoom siv rau saum npoo ntawm zaj duab xis sib xyaw.
Zaj duab xis BOPP kuj muaj qhov tsis zoo, xws li yooj yim rau kev sib sau ua ke hluav taws xob zoo li qub, tsis muaj kev sib khi cua sov thiab lwm yam. Hauv cov kab ntau lawm ceev ceev, zaj duab xis BOPP yooj yim raug hluav taws xob zoo li qub, xav tau kev teeb tsa cov cuab yeej tshem tawm hluav taws xob zoo li qub.
Yuav kom tau txais cov yeeb yaj kiab BOPP uas kaw tau kub, BOPP zaj duab xis corona kho tau tuaj yeem coated nrog cov nplaum kub-kaw resin, xws li PVDC latex, EVA latex, thiab lwm yam. Kuj tseem tuaj yeem coated nrog cov nplaum solvent, tab sis kuj tseem siv extrusion txheej lossis co-extrusion laminating txoj kev los tsim cov yeeb yaj kiab BOPP uas kaw tau kub. Cov yeeb yaj kiab no siv dav hauv cov khoom ntim mov ci, khaub ncaws, khau thiab thom khwm, nrog rau cov luam yeeb, phau ntawv npog ntim.
Tom qab ncab, lub zog tsim kua muag ntawm BOPP zaj duab xis pib nce ntxiv, tab sis lub zog tsim kua muag thib ob qis heev, yog li ntawd, zaj duab xis BOPP tsis tuaj yeem tso rau ob sab ntawm lub ntsej muag kawg ntawm qhov notch, txwv tsis pub zaj duab xis BOPP yooj yim rhuav thaum luam ntawv, laminating.
BOPP coated nrog daim kab xev nplaum uas tuaj yeem tsim los kaw lub thawv daim kab xev, yog BOPP koob tshuaj BOPP coated tus kheej nplaum tuaj yeem tsim daim kab xev sealing, yog BOPP siv hauv kev lag luam loj dua.
Cov yeeb yaj kiab BOPP tuaj yeem tsim los ntawm txoj kev ua yeeb yaj kiab raj lossis txoj kev ua yeeb yaj kiab tiaj tiaj. Cov yam ntxwv ntawm cov yeeb yaj kiab BOPP tau los ntawm ntau txoj kev ua tiav yog txawv. Cov yeeb yaj kiab BOPP tsim los ntawm txoj kev ua yeeb yaj kiab tiaj tiaj vim muaj qhov sib piv loj (txog li 8-10), yog li lub zog siab dua li txoj kev ua yeeb yaj kiab raj, qhov sib npaug ntawm cov yeeb yaj kiab kuj zoo dua.
Yuav kom tau txais kev ua tau zoo dua, feem ntau siv cov txheej txheem ntau txheej sib xyaw ua ke los tsim cov txheej txheem sib xyaw ua ke. BOPP tuaj yeem sib xyaw nrog ntau yam khoom sib txawv kom tau raws li qhov xav tau ntawm cov ntawv thov tshwj xeeb. Xws li BOPP tuaj yeem sib xyaw nrog LDPE (CPP), PE, PT, PO, PVA, thiab lwm yam kom tau txais qib siab ntawm cov pa roj, cov dej noo, pob tshab, tiv taus kub thiab txias, ua noj ua haus thiab tiv taus roj, cov yeeb yaj kiab sib xyaw ua ke sib txawv tuaj yeem siv rau cov khoom noj roj.
Qhov thib peb, lub hom phiaj tseem ceeb ntawm CPP zaj duab xis
CPP: pob tshab zoo, ci ntsa iab, tawv zoo, tiv thaiv dej noo zoo, tiv taus kub zoo, yooj yim rau cua sov sealing thiab lwm yam.
Zaj duab xis CPP tom qab luam ntawv, ua lub hnab, tsim nyog rau: khaub ncaws, khaub ncaws xaws thiab paj hnab; zaj duab xis cov ntaub ntawv thiab albums; ntim khoom noj; thiab rau kev ntim khoom thaiv thiab zaj duab xis kho kom zoo nkauj.
Tej zaum yuav siv tau xws li: qhwv khoom noj, qhwv khoom qab zib (zaj duab xis ntswj), ntim tshuaj (hnab tshuaj), hloov PVC hauv cov phau duab, cov ntawv tais ceev tseg thiab cov ntaub ntawv, ntawv tsim, daim kab xev nplaum, cov ntawv tuav daim npav ua lag luam, cov ntawv khi nplhaib thiab cov hnab sawv ntsug.
CPP muaj kev tiv taus cua sov zoo heev.
Vim tias qhov softening point ntawm PP yog li 140 ° C, hom zaj duab xis no tuaj yeem siv rau hauv cov chaw xws li kub-filling, steaming hnab thiab aseptic ntim.
Ua ke nrog kev tiv taus cov kua qaub, alkali thiab roj zoo heev, nws ua rau nws yog cov khoom siv xaiv hauv cov chaw xws li cov khoom ntim khoom noj lossis cov ntaub ntawv laminated.
Nws txoj kev nyab xeeb ntawm kev sib cuag nrog zaub mov, kev ua tau zoo heev, yuav tsis cuam tshuam rau qhov saj ntawm cov zaub mov sab hauv, thiab tuaj yeem xaiv ntau qib ntawm cov resin kom tau txais cov yam ntxwv xav tau.
