Laminated films yog tsim los ntawm ob lossis ntau txheej ntawm cov khoom sib txawv xws li PE, PP.PVC thiab PS thiab PET polymers nrog ntawv lossis hlau foils.Lawv yog cov mainlu siv nyob rau hauv lub packing.Hauv qab no peb tham txog laminated films ntau lawm khoom siv tes ua thiab cov yam ntxwv ntawm nws raws li zoo raws li lublaminated zaj duab xis recycling.
Feem ntau muaj peb hom khoom siv tes ua los ua ke.Ua ntej extruding composite txheej txheem yog yaj cov resin (polyethylene, polypropylene, EVA, ion resin, thiab lwm yam) raws li cov nplaum los yog thermal txheej, coated rau ntau yam ntawm cov yeeb yaj kiab los ua ke, thiab tom qab ntawd ua haujlwm los ntawm kev ua kom txias, kho. yog siv ob substrate, nws yog extrusion composite. Txwv tsis pub nws yog extrusion txheej.Thib ob, cov txheej txheem ntub dej sib xyaw siv cov kua nplaum dej-soluble.Nws tus yam ntxwv yog thawj sib xyaw, ces qhuav.Thaum ob lub substrates haum ua ke, tseem muaj ntau qhov hnyav ntawm cov nplaum nplaum.Cov txheej txheem ntub dej feem ntau yog siv rau hauv daim ntawv thiab lwm cov txheej txheem sib xyaw ua ke.Nws yog dav siv nyob rau hauv ntim luam yeeb, khoom qab zib ntawv / ob txheej ntawm txhuas composite khoom.Thirdly Solvent-based dry composite process and solvent-free dry composite process muaj cov ntsiab lus sib xws: thaum ob lub substrates haum ua ke, tsis muaj qhov hnyav lossis thinner hauv cov kua nplaum txheej txheej ntawm cov nplaum substrate.Cov txheej txheem ob yog sib sau ua ke raws li cov txheej txheem qhuav sib xyaw.Tab sis muaj qhov sib txawv ntawm lawv: cov qub siv cov kua nplaum los yog feem ntau hu ua kua nplaum muaj cov kuab tshuaj, tom kawg siv cov kua nplaum los yog cov kua nplaum tsis muaj cov kuab tshuaj.Yog li ntawd, ntawm cov kuab tshuaj dawb. qhuav composite tshuab, lub thawv kom qhuav yog ib qho tsim nyog.
Cov yam ntxwv ntawm cov yeeb yaj kiab composited:
1.Dej vapor barrier, tiv thaiv cov khoom ntub dej kom qhuav thiab siv rau cov ntaub ntub dej txias: tiv thaiv cov khoom qhuav los ntawm cov dej noo, xws li cov khoom ci, cov khoom siv hmoov.
2. Acid khoom barrier.Tiv thaiv oxidation, xws li rau cov rog thiab cov khoom tshiab.
3. Cov pa roj carbon dioxide barrier.Kev tiv thaiv CO 2 poob hauv MAP ntim thiab ua tiav cov ntim khoom ruaj khov nrog cov dej qab zib carbonated.
4. Fragrance barrier. Tiv thaiv cov ntxhiab tsw ntawm lub ntim thiab poob nyiaj xws li kas fes.
5. Smell barrier. Tiv thaiv kom tsis txhob muaj ntxhiab tsw sab nraud lossis tiv thaiv kom tsis txhob muaj ntxhiab tsw.
6. Lub teeb barrier.Kev tiv thaiv lub teeb oxidation xws li cov khoom siv mis nyuj.
7. Kaw nws kom ruaj khov.Rau qhov kev sib khi ntawm cov zaj duab xis sib xyaw, siv lub sealing kub.
Rau kev rov ua dua peb siv lubtsis siv neeg pelletizing recycling system.Nrog siv conveyer, cutter compactor thiab extruder, pelletizing thiab dewatering thiab cua kis tau tus mob thiab packing.Hauv qab no yog cov duab ntawm cov tshuab.
