OPP zaj duab xis yog ib hom polypropylene zaj duab xis, uas yog hu ua co-extruded oriented polypropylene (OPP) zaj duab xis vim cov txheej txheem ntau lawm yog ntau txheej extrusion. Yog tias muaj cov txheej txheem ob-directional stretching hauv kev ua, nws yog hu ua bi-directional oriented polypropylene zaj duab xis (BOPP). Lwm qhov yog hu ua cam khwb cia polypropylene zaj duab xis (CPP) as opposed to the co-extrusion process. Peb cov yeeb yaj kiab txawv ntawm lawv cov khoom thiab kev siv.
I. Kev siv tseem ceeb ntawm OPP zaj duab xis
OPP: taw qhia polypropylene (zaj duab xis), taw qhia polypropylene, yog ib hom polypropylene.
Cov khoom tseem ceeb ntawm OPP:
1, OPP daim kab xev: polypropylene zaj duab xis raws li lub substrate, nrog lub zog tensile siab, lub teeb yuag, tsis muaj tshuaj lom, tsis qab, ib puag ncig tus phooj ywg, ntau yam kev siv thiab lwm yam zoo
2, OPP daim ntawv lo:rau kev ua lag luam yog cov saturated thiab homogenized txhua hnub cov khoom, tsos yog txhua yam, thawj qhov kev xav txiav txim siab tus neeg siv khoom tus cwj pwm yuav khoom. tsuaj zawv plaub hau, da dej gel, detergents thiab lwm yam khoom yog siv nyob rau hauv sov thiab ntub chav da dej thiab chav ua noj, qhov yuav tsum tau ntawm daim ntawv lo kom tiv taus ya raws thiab tsis poob tawm, thiab nws tsis kam mus extrusion yuav tsum tau txuam nrog lub raj mis, thaum lub raj mis pob tshab rau. lub pob tshab ntawm cov nplaum thiab cov ntaub ntawv sau npe muab rau cov kev xav tau hnyav.
OPP cov ntawv txheeb ze rau daim ntawv lo, nrog pob tshab, lub zog siab, noo noo, tsis yooj yim rau poob thiab lwm yam zoo, txawm tias tus nqi nce, tab sis tuaj yeem tau txais daim ntawv lo zoo heev thiab siv tau. Tab sis tuaj yeem tau txais daim ntawv lo zoo heev thiab siv cov nyhuv. Nrog rau kev tsim cov tshuab luam ntawv hauv tsev, txheej thev naus laus zis, kev tsim cov ntawv nplaum rau tus kheej thiab cov ntawv luam yeeb yaj kiab tsis muaj teeb meem, nws tuaj yeem kwv yees tias kev siv cov ntawv OPP hauv tsev yuav nce ntxiv.
Raws li daim ntawv lo nws tus kheej yog PP, tuaj yeem ua ke zoo nrog PP / PE thawv ntim, kev xyaum tau ua pov thawj tias OPP zaj duab xis tam sim no yog cov khoom siv zoo tshaj plaws rau cov ntawv sau pwm, zaub mov thiab kev lag luam tshuaj txhua hnub hauv Tebchaws Europe tau siv ntau daim ntawv thov, thiab maj mam kis mus rau hauv tsev, muaj ntau thiab ntau cov neeg siv pib them sai sai rau los yog siv nyob rau hauv-pwm labeling txheej txheem.
Qhov thib ob, lub hom phiaj tseem ceeb ntawm BOPP zaj duab xis
BOPP: Biaxially oriented polypropylene zaj duab xis, kuj yog ib hom polypropylene.
Feem ntau siv BOPP zaj duab xis suav nrog:
● general bi-oriented polypropylene zaj duab xis,
● Thaum tshav kub kub-sealed bi-oriented polypropylene zaj duab xis,
● luam yeeb ntim zaj duab xis,
● bi-oriented polypropylene pearlescent zaj duab xis,
● bi-oriented polypropylene metallized zaj duab xis,
● matte zaj duab xis thiab lwm yam.
Cov kev siv tseem ceeb ntawm ntau yam yeeb yaj kiab yog raws li hauv qab no:
1, Ordinary BOPP zaj duab xis
Feem ntau yog siv rau kev luam ntawv, lub hnab ua, ua cov nplaum nplaum thiab sib xyaw nrog lwm cov substrates.
2 、 BOPP cua sov sealing zaj duab xis
Feem ntau yog siv rau kev luam ntawv, lub hnab ua thiab lwm yam.
3, BOPP luam yeeb ntim zaj duab xis
Siv: Siv rau kev ntim luam yeeb kub ceev.
4, BOPP pearlized zaj duab xis
Siv rau cov khoom noj thiab cov khoom siv hauv tsev tom qab luam ntawv.
5, BOPP Metallized Zaj duab xis
Siv raws li lub tshuab nqus tsev metallization, hluav taws xob, tiv thaiv kev ua txhaum cai substrate, ntim khoom noj.
6, BOPP matte zaj duab xis
Siv rau xab npum, zaub mov, luam yeeb, tshuaj pleev ib ce, tshuaj thiab lwm lub thawv ntim khoom.
7, BOPP anti-fog zaj duab xis
Siv rau ntim zaub, txiv hmab txiv ntoo, sushi, paj thiab lwm yam.
BOPP zaj duab xis yog ib qho tseem ceeb ntawm cov khoom ntim khoom siv, dav siv.
BOPP zaj duab xis tsis muaj xim, tsis muaj ntxhiab, tsis qab, tsis muaj tshuaj lom, thiab muaj lub zog tensile siab, cuam tshuam lub zog, rigidity, toughness thiab zoo transparency.
BOPP zaj duab xis nto zog yog tsawg, kua nplaum los yog luam ntawv ua ntej kho corona. Txawm li cas los xij, BOPP zaj duab xis tom qab kev kho mob corona, muaj kev hloov pauv tau zoo, tuaj yeem ua xim luam ntawv thiab tau txais qhov zoo nkauj zoo nkauj, thiab yog li feem ntau siv los ua cov khoom sib xyaw ua ke.
BOPP zaj duab xis kuj tseem muaj qhov tsis zoo, xws li yooj yim kom muaj hluav taws xob zoo li qub, tsis muaj cua sov sealing thiab lwm yam. Nyob rau hauv high-ceev ntau lawm kab, BOPP zaj duab xis yog nquag mus rau static hluav taws xob, yuav tsum tau rau nruab static hluav taws xob tshem tawm.
Txhawm rau kom tau txais BOPP zaj duab xis thaum tshav kub kub, BOPP zaj duab xis saum npoo corona kho tuaj yeem coated nrog cov khoom siv hluav taws xob uas muaj cov nplaum nplaum, xws li PVDC latex, EVA latex, thiab lwm yam, tuaj yeem coated nrog hnyav nplaum, tab sis kuj extrusion txheej lossis co. -extrusion laminating txoj kev yuav siv tau los tsim tshav kub-sealable BOPP zaj duab xis. Cov yeeb yaj kiab yog siv dav hauv cov khob cij, khaub ncaws, khau thiab thom khwm ntim, nrog rau cov luam yeeb, phau ntawv npog ntim.
BOPP zaj duab xis pib ntawm lub zog tsim kua muag tom qab ncab tau nce, tab sis qhov thib ob lub zog tsim kua muag tsawg heev, yog li BOPP zaj duab xis tsis tuaj yeem tso rau ntawm ob sab ntawm lub ntsej muag kawg ntawm qhov ntsuas, txwv tsis pub BOPP zaj duab xis yog yooj yim los tsim kua muag hauv luam ntawv. , lamination.
BOPP coated nrog nws tus kheej-nplaum daim kab xev tuaj yeem tsim los kaw lub thawv daim kab xev, yog BOPP ntau npaum BOPP coated self-adhesive tuaj yeem tsim daim kab xev sealing, yog BOPP siv ntawm lub khw loj.
BOPP zaj duab xis tuaj yeem tsim los ntawm txoj kev ua yeeb yaj kiab los yog txoj kev ua yeeb yaj kiab. Cov khoom ntawm BOPP cov yeeb yaj kiab tau los ntawm cov txheej txheem sib txawv yog txawv. BOPP zaj duab xis tsim los ntawm txoj kev tiaj tus zaj duab xis vim qhov loj tensile piv (txog li 8-10), yog li lub zog siab dua li cov yeeb yaj kiab yeeb yaj kiab, zaj duab xis thickness uniformity kuj zoo dua.
Txhawm rau kom tau txais kev ua tau zoo tag nrho, hauv kev siv cov txheej txheem feem ntau yog siv los tsim cov txheej txheem ntau txheej txheej.BOPP tuaj yeem sib xyaw nrog ntau yam khoom sib txawv kom tau raws li qhov xav tau ntawm kev siv 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 roj barrier, noo noo barrier, transparency, siab thiab kub tsis kam, ua noj ua haus thiab roj kuj, sib txawv composite cov yeeb yaj kiab tuaj yeem siv rau cov zaub mov oily.
Peb, lub hom phiaj tseem ceeb ntawm CPP zaj duab xis
CPP: zoo pob tshab, siab gloss, zoo txhav, zoo noo noo barrier, zoo heev tshav kub tsis kam, yooj yim rau cua sov sealing thiab hais txog.
CPP zaj duab xis tom qab luam ntawv, lub hnab ua, haum rau: khaub ncaws, knitwear thiab paj hnab; cov ntaub ntawv thiab albums zaj duab xis; ntim khoom noj; thiab rau kev ntim khoom thiab cov khoom siv zoo nkauj metallized zaj duab xis.
Muaj peev xwm siv tau kuj muaj xws li: zaub mov overwrap, confectionery overwrap (twisted zaj duab xis), tshuaj ntim (infusion hnab), hloov PVC nyob rau hauv cov duab albums, folders thiab cov ntaub ntawv, hluavtaws ntawv, nws tus kheej-nplaum tapes, lub lag luam daim ntawv tuav, lub nplhaib binders thiab sawv ntsug. hnab composites.
CPP muaj qhov ua kom sov zoo heev.
Txij li thaum lub softening point ntawm PP yog hais txog 140 ° C, hom zaj duab xis no yuav siv tau nyob rau hauv tej chaw xws li kub-filling, steaming hnab thiab aseptic ntim.
Coupled nrog zoo heev acid, alkali thiab roj kuj, nws ua rau nws cov khoom ntawm kev xaiv nyob rau hauv cov cheeb tsam xws li khob cij khoom ntim los yog laminated cov ntaub ntawv.
Nws cov zaub mov tiv thaiv kev nyab xeeb, kev nthuav qhia zoo heev, yuav tsis cuam tshuam qhov tsw ntawm cov zaub mov sab hauv, thiab tuaj yeem xaiv cov qib sib txawv ntawm cov resin kom tau txais cov yam ntxwv xav tau.
