Cov khoom siv ua haujlwm ntawm cov ntaub ntawv ntim cov yeeb yaj kiab ncaj qha ua rau kev txhim kho kev ua haujlwm ntawm cov khoom ntim khoom sib xyaw ua ke. Cov hauv qab no yog cov lus qhia luv luv rau kev ua haujlwm ntawm ntau yam khoom siv ntim khoom.
1. Cov khoom ntim khoom siv feem ntau: PE zaj duab xis
Thaum tshav kub kub-sealable PE cov ntaub ntawv tau hloov zuj zus los ntawm ib txheej tshuab cua tshuab mus rau ntau txheej co-extruded films, thiaj li hais tias cov qauv ntawm sab hauv, nruab nrab thiab txheej txheej yuav tsim txawv. Kev sib xyaw cov qauv tsim ntawm ntau hom polyethylene resins tuaj yeem tsim qhov sib txawv ntawm qhov sib txawv, qhov sib txawv ntawm qhov sib txawv ntawm qhov kub thiab txias, qhov sib txawv los tiv thaiv kev sib tsoo,hot nplaum muaj zog, los tiv thaiv zoo li qub, thiab lwm yam, kom ua tau raws li cov khoom ntim tshwj xeeb thiab cov ntaub ntawv PE zaj duab xis nrog cov khoom siv sib txawv.
Nyob rau hauv xyoo tas los no, biaxially oriented polyethylene (BOPE) films kuj tau tsim, uas txhim kho tensile lub zog ntawm polyethylene films thiab muaj zog dua kub-sealing.
2. CPP zaj duab xis khoom
CPP cov ntaub ntawv feem ntau yog siv rau hauv BOPP / CPP cov khoom ntim dej noo-pov thawj lub teeb, tab sis cov txheej txheem CPP sib txawv tuaj yeem ua los ntawm cov khoom siv sib txawv ntawm cov yeeb yaj kiab, xws li kev txhim kho qhov kub thiab txias, tsis kam ua kom kub kub, qis dua. sealing kub, siab puncture zog, corrosion kuj, thiab lwm yam kev ua haujlwm ntawm cov ntaub ntawv kub-sealing.
RIb xyoo dhau los, kev lag luam kuj tau tsim CPP matte zaj duab xis, ua kom pom cov nyhuv ntawm ib txheej CPP zaj duab xis hnab.
3. BOPP zaj duab xis cov ntaub ntawv
Lub teeb ntim cov yeeb yaj kiab feem ntau yog siv los ua cov yeeb yaj kiab BOPP zoo tib yam thiab BOPP matte zaj duab xis, kuj tseem muaj BOPP thaum tshav kub kub sealing zaj duab xis (ib sab los yog ob sab cua sov sealing), BOPP pearl zaj duab xis.
BOPP yog tus cwj pwm los ntawm lub zog tensile siab (tsim rau ntau xim overprinting), zoo heev dej vapor barrier zog, dav siv nyob rau hauv noo noo-resistant lub teeb ntim ntawm lub ntsej muag ntawm cov ntaub ntawv luam tawm.
BOPP matte zaj duab xis nrog matte hniav zoo ib yam li daim ntawv. BOPP tshav kub sealing zaj duab xis tuaj yeem siv los ua ib txheej ntim cov ntaub ntawv, xws li rau qhwv lub ntim ntim khoom qab zib nrog. Bopp Pearl zaj duab xis feem ntau yog siv rau cov dej khov Ntim Ntim Cov Ntawv, 2 txog 3N / 15mm Sealing lub zog kom lub hnab yooj yim qhib kom qhib cov ntsiab lus.
Tsis tas li ntawd, xws li BOPP anti-fog zaj duab xis, holographic OPP laser zaj duab xis, PP hluavtaws ntawv, biodegradable BOPP zaj duab xis thiab lwm yam BOPP series ntawm functional films kuj tau nrov thiab siv nyob rau hauv ib tug tshwj xeeb ntau yam.
4. Cov ntaub ntawv ntim khoom siv feem ntau: PET cov khoom siv zaj duab xis
Ordinary 12MICRONS PET lub teeb zaj duab xis yog dav siv hauv cov khoom ntim sib xyaw ua ke, lub zog ntawm nws cov khoom ntim khoom laminated ntau dua li BOPP ob txheej txheej khoom sib xyaw (me ntsis qis dua li BOPA ob txheej txheej khoom), thiab lub peev xwm oxygen barrier. ntawm BOPP / PE (CPP) zaj duab xis sib xyaw kom txo tau 20 mus rau 30 zaug.
Lub tshav kub tsis kam ntawm cov ntaub ntawv PET yog qhov zoo heev, thiab tuaj yeem ua rau lub tiaj tiaj ntawm lub hnab zoo. PET tshav kub-shrinkable zaj duab xis, matte PET PET tshav kub-shrinkable zaj duab xis, matte PET zaj duab xis, high-barrier polyester zaj duab xis, PET twist zaj duab xis, linear tear PET zaj duab xis thiab lwm yam khoom siv kuj siv.
5. Cov khoom ntim khoom siv: nylon zaj duab xis
Biaxially oriented nylon zaj duab xis yog dav siv nyob rau hauv lub tshuab nqus tsev, boiling thiab steaming hnab rau nws lub zog siab, siab puncture kuj, siab kub kuj thiab zoo dua oxygen barrier.
Feem ntau lub peev xwm loj laminated hnab tshaj 1.7kg kuj siv BOPA // PE qauv rau kev poob zoo.
Cam khwb cia nylon zaj duab xis, dav siv nyob rau hauv Nyiv rau cov khoom noj khov ntim, uas muaj qhov kub thiab txias tsis kam, txo lub hnab tawg tus nqi thaum tsis tshua muaj kub cia thiab kev thauj mus los.
6. Cov Khoom Siv Ntim: Txhuas txheej Metalized Film
Lub tshuab nqus tsev aluminizing yog nyob rau hauv zaj duab xis (xws li tus tsiaj, BOPP, CPP, PE, PVC, thiab lwm yam) nto ntawm qhov tsim ntawm ib txheej ntawm tuab aluminium txheej, yog li ua kom cov yeeb yaj kiab ntawm cov dej vapor, oxygen, lub teeb barrier muaj peev xwm. , feem ntau dav siv nyob rau hauv cov khoom sib xyaw hloov tau VMPET, VMCPP cov ntaub ntawv.
VMPET rau peb-txheej laminating, VMCPP rau ob-txheej laminating.
OPP // VMPET // PE qauv tau tam sim no tau siv rau hauv cov xovxwm zaub, sprouts khoom nyob rau hauv lub tshuab nqus tsev boiling ntim. PE qauv tam sim no tau paub tab siv los nyem zaub, sprouts khoom nyob rau hauv lub tshuab nqus tsev boiling ntim, thiaj li yuav kov yeej cov shortcomings ntawm zoo tib yam aluminized khoom, txhuas txheej yooj yim rau migrate, tsis txhob tiv cov shortcomings ntawm boiling, txoj kev loj hlob ntawm VMPET cov khoom nrog hom txheej hauv qab, ua ntej thiab tom qab boiling ntawm tev lub zog ntawm ntau tshaj 1.5N / 15mm, thiab txhuas txheej tsis tshwm sim tsiv teb tsaws, txhim khu lub zuag qhia tag nrho barrier kev ua tau zoo ntawm lub hnab.
7. Cov khoom ntim khoom siv: Aluminium ntawv ci
Aluminium ntawv nyiaj rau kev ntim khoom yooj yim yog feem ntau 6.5μm sau 9μm 12microns thickness, aluminium ntawv ci yog theoretically yog ib qho khoom thaiv siab, dej permeability, oxygen permeability, lub teeb permeability yog "0", tab sis qhov tseeb muaj pinholes nyob rau hauv lub txhuas ntawv ci thiab folding tsis zoo pinhole kuj, muaj ib tug xov tooj ntawm tiag barrier ntim. cov nyhuv tsis zoo tagnrho. Tus yuam sij rau daim ntawv thov ntawm txhuas ntawv nyiaj yog kom tsis txhob pinholes thaum lub sij hawm ua, ntim thiab kev thauj mus los, yog li txo qhov muaj peev xwm barrier. Nyob rau hauv xyoo tas los no, muaj kev nyiam rau cov ntaub ntawv aluminium foil los hloov los ntawm cov khoom ntim khoom lag luam ntau dua hauv lawv cov ntawv thov ib txwm muaj.
8. Feem ntau siv cov khoom ntim: coated high-barrier films
Feem ntau PVDC coated zaj duab xis (K txheej zaj duab xis), PVA coated zaj duab xis (Ib zaj duab xis txheej).
PVDC muaj cov pa tiv thaiv zoo heev thiab cov dej noo tsis kam, thiab muaj qhov pom tseeb zoo, coated PVDC zaj duab xis siv hauv cov yeeb yaj kiab feem ntau yog BOPP, BOPET, BOPA, CPP, thiab lwm yam, tab sis kuj tuaj yeem ua PE, PVC, cellophane thiab lwm yam yeeb yaj kiab, Composite saj zawg zog ntim nyob rau hauv feem ntau siv KOPP, KPET, KPA zaj duab xis.
9. Cov Khoom Siv Ntim: Co-extruded High Barrier Films
Co-extrusion yog ob los yog ntau yam yas sib txawv, los ntawm ob los yog ntau tshaj ob extruders, raws li, kom muaj ntau yam plastics melting thiab plasticizing rau ib tug khub ntawm lub taub hau tuag, kev npaj ntawm composite films ntawm ib txoj kev molding. Co-extruded barrier composite films feem ntau yog tsim los ntawm kev sib xyaw ntawm cov khoom siv yas, polyolefin plastics thiab cov nplaum nplaum ntawm peb hom ntaub ntawv loj, cov khoom siv barrier feem ntau yog PA, EVOH, PVDC, thiab lwm yam.
Cov saum toj no tsuas yog cov khoom ntim khoom nkaus xwb, qhov tseeb, tsawg kawg yog kev siv cov oxide vapor txheej, PVC, PS, PEN, ntawv, thiab lwm yam, thiab cov khoom siv tib yam raws li cov txheej txheem sib txawv, cov qauv sib txawv tuaj yeem tsim los ntawm kev hloov kho ntawm qhov sib txawv. kev ua haujlwm ntawm cov khoom siv zaj duab xis. Lamination ntawm cov yeeb yaj kiab sib txawv, los ntawm lamination qhuav, tsis muaj kuab tshuaj lamination, extrusion lamination thiab lwm yam cuab yeej siv los tsim cov khoom siv sib xyaw ua ke kom tau raws li cov kev xav tau sib txawv.cov khoomntim.
