Cov yam ntxwv ua haujlwm ntawm cov ntaub ntawv ntim khoom ua rau muaj kev txhim kho kev ua haujlwm ntawm cov ntaub ntawv ntim khoom sib xyaw ua ke. Cov hauv qab no yog kev qhia luv luv txog cov yam ntxwv ua haujlwm ntawm ntau cov ntaub ntawv ntim khoom siv feem ntau.
1. Cov ntaub ntawv ntim khoom siv feem ntau: PE zaj duab xis
Cov ntaub ntawv PE uas kaw tau cua sov tau hloov zuj zus los ntawm cov yeeb yaj kiab ib txheej mus rau ntau txheej co-extruded zaj duab xis, yog li cov qauv ntawm cov txheej sab hauv, nruab nrab thiab sab nraud tuaj yeem tsim sib txawv. Kev tsim cov mis sib xyaw ntawm ntau hom polyethylene resins tuaj yeem tsim cov kub sib txawv, cov kub sib txawv ntawm cov cua sov-sealing, cov khoom sib txawv tiv thaiv kev sib kis,htsis muaj zog nplaum, cov teebmeem tiv thaiv zoo li qub, thiab lwm yam, kom ua tau raws li cov kev xav tau tshwj xeeb ntawm cov khoom ntim khoom thiab cov ntaub ntawv PE zaj duab xis nrog cov yam ntxwv ua haujlwm sib txawv.
Nyob rau hauv xyoo tas los no, cov yeeb yaj kiab biaxially oriented polyethylene (BOPE) kuj tau tsim, uas txhim kho lub zog tensile ntawm cov yeeb yaj kiab polyethylene thiab muaj lub zog kub-sealing siab dua.
2. Cov Khoom Siv Zaj Duab Xis CPP
Cov ntaub ntawv CPP feem ntau siv rau hauv BOPP / CPP cov qauv ntim khoom uas tsis muaj dej noo, tab sis cov qauv sib txawv ntawm CPP resin kuj tuaj yeem ua rau cov khoom siv sib txawv ntawm zaj duab xis, xws li kev tiv taus kub tsawg dua, kev ua noj kub siab, qhov kub qis dua, lub zog siab, kev tiv taus corrosion, thiab lwm yam khoom siv ntawm cov ntaub ntawv kub-sealing.
RXyoo tas los no, kev lag luam kuj tau tsim cov yeeb yaj kiab CPP matte, ua rau pom kev zoo ntawm cov hnab yas CPP ib txheej.
3. Cov ntaub ntawv BOPP zaj duab xis
Cov yeeb yaj kiab sib xyaw ua ke feem ntau yog siv rau cov yeeb yaj kiab BOPP ib txwm thiab cov yeeb yaj kiab matte, kuj tseem muaj cov yeeb yaj kiab kub BOPP (ib sab lossis ob sab kub), BOPP zaj duab xis hlaws.
BOPP yog tus cwj pwm los ntawm lub zog tensile siab (haum rau ntau xim overprinting), zoo heev dej vapor barrier zog, dav siv rau hauv cov dej noo-resistant lub teeb ntim ntawm lub ntsej muag ntawm cov ntaub ntawv luam tawm.
BOPP zaj duab xis matte nrog cov nyhuv kho kom zoo nkauj zoo ib yam li daim ntawv. BOPP zaj duab xis kaw cua sov siv tau ua cov khoom ntim ib txheej, xws li siv rau kev qhwv cov khoom qab zib sab hauv. BOPP zaj duab xis hlaws feem ntau siv rau kev ntim khoom qab zib khov kho cua sov, tuaj yeem txuag tau cov ntawv luam tawm dawb, nws qhov ceev tsawg, 2 txog 3N / 15mm lub zog kaw kom lub hnab yooj yim qhib thiab tshem tawm cov ntsiab lus.
Tsis tas li ntawd xwb, xws li BOPP anti-fog film, holographic OPP laser film, PP synthetic paper, biodegradable BOPP film thiab lwm yam BOPP series ntawm cov yeeb yaj kiab ua haujlwm kuj tau nrov thiab siv rau hauv ib qho tshwj xeeb.
4. Cov ntaub ntawv ntim khoom siv feem ntau: Cov khoom siv zaj duab xis PET
Cov yeeb yaj kiab PET 12MICRONS feem ntau siv dav hauv cov khoom ntim khoom sib xyaw ua ke, lub zog kho tshuab ntawm nws cov khoom ntim laminated siab dua li cov khoom sib xyaw BOPP ob txheej (qis dua li cov khoom sib xyaw BOPA ob txheej), thiab lub peev xwm thaiv pa oxygen ntawm cov yeeb yaj kiab sib xyaw BOPP / PE (CPP) kom txo tau 20 txog 30 zaug.
Qhov tiv taus cua sov ntawm cov ntaub ntawv PET zoo heev, thiab tuaj yeem ua rau lub hnab zoo tiaj tus. Cov yeeb yaj kiab PET kub-shrinkable, matte PET PET 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
Cov yeeb yaj kiab nylon biaxially oriented yog siv dav hauv lub hnab nqus tsev, lub hnab ua kom npau thiab lub hnab steaming rau nws lub zog siab, tiv taus qhov tho qhov siab, tiv taus kub thiab tiv taus oxygen zoo dua.
Feem ntau cov hnab yas uas muaj peev xwm loj dua 1.7kg kuj siv cov qauv BOPA//PE rau kev tiv thaiv kev poob zoo.
Zaj duab xis nylon cam khwb cia, siv dav hauv Nyiv Pooj rau kev ntim khoom noj khov, uas muaj kev tiv taus kub qis zoo, txo qhov tawg ntawm lub hnab thaum lub sijhawm khaws cia thiab thauj mus los ntawm qhov kub qis.
6. Cov Khoom Siv Ntim Khoom Siv: Aluminium txheej Metalized Film
Cov txheej txheem aluminizing hauv zaj duab xis (xws li PET, BOPP, CPP, PE, PVC, thiab lwm yam) yog ua los ntawm cov khoom siv aluminium tuab, uas ua rau cov dej ua pa, oxygen, thiab lub teeb ci ntsa iab ntau dua, thiab feem ntau siv VMPET, VMCPP cov ntaub ntawv hauv cov khoom sib xyaw ua ke.
VMPET rau peb txheej laminating, VMCPP rau ob txheej laminating.
Cov qauv OPP // VMPET // PE tam sim no tau siv rau hauv kev nias zaub, cov khoom cog qoob loo hauv lub hnab ntim khoom nqus tsev. Cov qauv PE tam sim no tau siv rau kev nias zaub, cov khoom cog qoob loo hauv lub hnab ntim khoom nqus tsev, txhawm rau kov yeej qhov tsis zoo ntawm cov khoom siv aluminium ib txwm muaj, txheej txhuas yooj yim rau kev tsiv teb tsaws chaw, tsis tiv taus qhov tsis zoo ntawm kev npau, kev tsim cov khoom VMPET nrog hom txheej hauv qab, ua ntej thiab tom qab npau ntawm lub zog tev tawv ntau dua 1.5N / 15mm, thiab txheej txhuas zoo li tsis tsiv teb tsaws chaw, txhim kho kev ua haujlwm thaiv tag nrho ntawm lub hnab.
7. Cov ntaub ntawv ntim khoom siv: Cov ntawv txhuas
Cov ntawv ci txhuas rau kev ntim khoom yooj ywm feem ntau yog 6.5μm los yog 9μm 12microns tuab, cov ntawv ci txhuas yog theoretically ib qho khoom siv thaiv siab, dej permeability, oxygen permeability, lub teeb permeability yog "0", tab sis qhov tseeb muaj pinholes hauv cov ntawv ci txhuas thiab folding tsis zoo pinhole tsis kam, muaj ntau qhov tseeb barrier ntim nyhuv tsis zoo tagnrho. Qhov tseem ceeb rau kev siv cov ntawv ci txhuas yog kom tsis txhob muaj pinholes thaum lub sijhawm ua, ntim khoom thiab thauj mus los, yog li txo qhov tseeb barrier peev xwm. Nyob rau hauv xyoo tas los no, muaj ib qho kev nyiam rau cov ntaub ntawv txhuas ntawv ci hloov los ntawm cov ntaub ntawv ntim khoom pheej yig dua hauv lawv cov chaw siv ib txwm muaj.
8. Cov ntaub ntawv ntim khoom siv feem ntau: cov yeeb yaj kiab uas muaj cov khoom thaiv siab
Feem ntau yog PVDC coated zaj duab xis (K txheej zaj duab xis), PVA coated zaj duab xis (A txheej zaj duab xis).
PVDC muaj cov pa oxygen zoo heev thiab cov dej noo tsis kam, thiab muaj cov pob tshab zoo heev, cov zaj duab xis PVDC uas siv rau hauv cov zaj duab xis puag feem ntau yog BOPP, BOPET, BOPA, CPP, thiab lwm yam, tab sis kuj tuaj yeem yog PE, PVC, cellophane thiab lwm yam zaj duab xis, hauv cov ntim khoom sib xyaw ua ke feem ntau yog siv KOPP, KPET, KPA zaj duab xis.
9. Cov Khoom Siv Ntim Khoom Siv: Cov Yeeb Yaj Kiab Uas Muaj Kev Tiv Thaiv Siab
Co-extrusion yog ob lossis ntau hom yas sib txawv, los ntawm ob lossis ntau dua ob lub tshuab extruder, feem, kom ntau yam yas yaj thiab yas rau ib khub lub taub hau tuag, thiab ua cov zaj duab xis sib xyaw ua ke raws li txoj kev molding. Cov zaj duab xis sib xyaw ua ke feem ntau yog ua los ntawm kev sib xyaw ua ke ntawm cov yas sib xyaw, polyolefin yas thiab cov nplaum resins ntawm peb hom ntaub ntawv tseem ceeb, cov resins feem ntau yog PA, EVOH, PVDC, thiab lwm yam.
Qhov saum toj no tsuas yog cov ntaub ntawv ntim khoom siv xwb, qhov tseeb, tsawg kawg yog siv cov txheej oxide vapor, PVC, PS, PEN, ntawv, thiab lwm yam, thiab tib cov resin raws li cov txheej txheem ua tiav sib txawv, cov qauv sib txawv tuaj yeem tsim los ntawm kev hloov kho cov khoom siv sib txawv ntawm cov khoom siv zaj duab xis. Lamination ntawm cov yeeb yaj kiab sib txawv, los ntawm kev lamination qhuav, lamination tsis muaj kuab paug, extrusion lamination thiab lwm yam thev naus laus zis sib xyaw los tsim cov khoom siv sib xyaw ua ke yooj ywm kom tau raws li qhov xav tau ntawm ntau yam.cov khoomntim khoom.
