Sequential BOPA Nrog Ob Sab Corona kho
OA2 yog ob sab corona kho sequential BOPA nrog cov khoom zoo tag nrho.Nws feem ntau yog siv los ua cov txheej txheem nruab nrab thiab txheej txheem txheej txheem xws li txheej thiab metallization daim ntawv thov.
| Nta | Cov txiaj ntsig |
| ✦ Zoo flex crack kuj; ✦ Zoo lub zog thiab puncture / cuam tshuam tsis kam | ✦ Haum rau kev ntim khoom sib txawv; ✦ Muaj peev xwm ntim cov khoom hnyav, cov khoom ntse lossis cov khoom tsis nruj nrog kev ruaj ntseg ntim zoo |
| ✦ High gas barrier; ✦ Cov ntawv thov zoo heev ntawm qhov kub thiab txias; ✦ Ntau yam thickness; ✦ Zoo meej; ✦ Customization | ✦ 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; ✦ Ua tau raws li cov neeg siv khoom xav tau |
| 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.

OA2 tuaj yeem siv los tsim cov ntim ntim khoom yooj yim hauv 3 xim (xws li 3 xim), sealing dav≤1cm thiab tsis tas yuav tsum tau luam ntawv sau npe, xws li lub hnab khoob, lub hnab ntim khoom noj, lub hnab ntim dej, thiab lub hnab ntim khoom ntim.Cov ntawv thov tshwj xeeb raws li hauv qab no, lub hnab ntim rau cov txiv ntoo (walnuts, cov noob paj noob hlis, thiab lwm yam) thiab lub hnab ntim rau cov khoom noj nqaij (Texas grilled nqaij qaib, steak, thiab lwm yam), cov khoom siv hluav taws xob tiv thaiv, ntim kua, xws li cawv, dej haus, ntses , lub hnab ntim mis, dej cia hnab, ginseng nqaij qaib kua zaub, roj hnab, lub hnab ntim khoom noj, aerospace zaub mov, nyob ntses hnab, txias thiab tshiab nqaij, nqaij nruab deg, halogen xauv tshiab ntim, thiab lwm yam.
Xim Penetration
Nws yog qhov yooj yim tshwm sim hauv NY / PE (CPP) qauv.Cov xim ntawm lub nplhaib npau npau yog ntau xim liab thiab ntshav thaum lub sijhawm ua noj.Yog tias txheej txheej txheej hloov mus rau PET nplhaib BOPP, ces xim nkag tau yooj yim tshwm sim.
Ua rau:
Kub thiab av noo (dej) yog ob lub ntsiab lus tseem ceeb uas ua rau xim nkag mus.
● Nylon resin yog thermoplastic polymer los ntawm semi-crystalline mus rau amorphous.Thaum qhov kub thiab txias, qhov ntau dua qhov kev hloov ntawm kev sib hloov ntawm cov molecules, qhov ntau dua qhov ua tau ntawm pigment migration.
● Cov dej tsis kam ntawm nylon tsis zoo, nyob rau hauv cov txheej txheem ntawm boiling, dej molecules nyob rau hauv nylon nyob rau hauv thiab tawm, ntxuav lub pigment Cheebtsam nyob rau hauv printing number case.
● Ib co pigments yog dej soluble.
Cov lus qhia ntsig txog:
✔ Siv ob hom kua dej polyurethane number case.
✔ Ntxiv cov tshuaj tua kab mob ntxiv rau cov kua nplaum rov qab.
