Sequential BOPA Nrog Ib Sab Corona kho
OA1 yog ib sab corona kho raws li BOPA nrog cov khoom zoo tag nrho uas tsim nyog rau cov ntawv ntim khoom.
| Nta | Cov txiaj ntsig |
| ✦ Zoo flex crack kuj; ✦ Lub zog zoo thiab puncture / cuam tshuam tsis kam; ✦ High gas barrier; ✦ Cov ntawv thov zoo heev ntawm qhov kub thiab txias; ✦ Ntau yam thickness; ✦ Zoo meej | ✦ Haum rau kev ntim khoom sib txawv; ✦ Muaj peev xwm ntim cov khoom hnyav, ntse lossis nruj nrog kev ruaj ntseg ntim zoo; ✦ Ntev lub neej txee; ✦ haum rau cov khoom noj khov thiab pasteurization / boiling daim ntawv thov; ✦ Thickness tailored rau txawv zog yuav tsum tau - nqi npaum; ✦ Zoo dua sensory zoo |
| Thickness / hli | Dav / hli | Kev kho mob | Retortability | Kev luam tawm |
| 10-30 | 300-2100 Nws | ib sab corona | ≤100 ℃ | ≤6 xim (pom zoo) |
Daim ntawv ceeb toom: retortability thiab printability yog nyob ntawm cov neeg muas zaub 'lamination thiab printing ua mob.

OA1 tuaj yeem siv rau kev ntim khoom ntim hauv 6 xim (xws li 6 xim) thiab ntim khoom zoo tib yam nrog ntug dav ≤ 3cm thiab tsis muaj qhov yuav tsum tau ua.Nws tuaj yeem khaws cov qib me me ntawm warping thiab curling tom qab boiling thiab haum rau ntim cov ntsiab lus hnyav nrog cov pob txha, cov txha nraub qaum uas yuav tsum tau muaj kev tiv thaiv siab rau kev sib tsoo thiab kev cuam tshuam, xws li cov pob khoom siv rau cov txiv hmab txiv ntoo (pickled mustard, xyoob tua, pickled zaub, thiab lwm yam. ), nqaij nruab deg, txiv ntseej, ntxuav hmoov, udong noodles, duck ntshav, txiv hmab txiv ntoo mos mos, pastry, hli ncuav mog qab zib, tsoos suav mov-pudding, dumplings, cov khoom xyaw kub lauj kaub, zaub mov khov, thiab lwm yam.
Cov txheej txheem ntawm Lamination txog Flexible Ntim
Cov txheej txheem ua tiav ntawm kev ntim khoom yooj yim feem ntau suav nrog cov khoom sib xyaw qhuav, ntub dej sib xyaw, extrusion puas, co-extrusion puas thiab lwm yam.
● Qhuav hom composite
Nyob rau hauv ntau yam kev siv thev naus laus zis ntawm cov yeeb yaj kiab sib xyaw, cov khoom sib xyaw qhuav yog cov tsoos tshaj plaws thiab cov cuab yeej siv dav siv hauv Suav teb, uas yog siv dav hauv ntim khoom noj, tshuaj, tshuaj pleev ib ce, khoom siv txhua hnub, cov khoom lag luam teeb, tshuaj, khoom siv hluav taws xob, thiab lwm yam. .
● Cov dej sib xyaw ntub dej
Kev sib xyaw ntub dej yog txhawm rau txheej txheej ntawm cov nplaum rau saum npoo ntawm cov khoom sib xyaw (yas zaj duab xis, aluminium ntawv ci).Thaum cov nplaum tsis qhuav, nws laminates nrog lwm cov ntaub ntawv (daim ntawv, cellophane) los ntawm lub siab cov menyuam, thiab tom qab ntawd qhuav rau hauv cov yeeb yaj kiab sib xyaw los ntawm qhov kub kom qhuav.
● Composite extrusion
Extrusion compound yog yaj polyethylene thiab lwm yam thermoplastic cov ntaub ntawv nyob rau hauv lub extruder tom qab extrusion mus rau hauv lub tiaj tuag lub qhov ncauj, ua daim ntawv zaj duab xis tawm tam sim ntawd thiab lwm los yog ob hom ntawm cov yeeb yaj duab los ntawm lub txias yob thiab composite xovxwm yob laminate ua ke.
● Extrude coated zaj duab xis
Extrusion txheej yog ib txoj hauv kev ua ib zaj duab xis sib xyaw los ntawm melting lub thermoplastic, xws li polyethylene tawm ntawm lub taub hau tiaj tus thiab nias nws tawm tsam lwm lub substrate ntawm ob lub rollers nyob ze.
● Extruded composite zaj duab xis
Extrusion compound yog extruded resin sandwiched nyob rau hauv nruab nrab ntawm ob lub substrates, nws yuav ua si ob lub substrates ua ke ua ke nplaum, tab sis kuj yog ib txheej txheej.
