MESIM BOPA Nrog Ntsuas Lub Cev Muaj Zog Thiab Hloov Hloov
SHA yog Biaxial Oriented Polyamide 6 zaj duab xis uas tsim los ntawm kev siv tshuab ib txhij ncab.
| Nta | Cov txiaj ntsig |
| ● Zoo oxygen / aroma barrier ● Zoo tshaj isotropy kev ua tau zoo hauv kev luam ntawv thiab retort | ● Lub neej txee ntev dua thiab zoo dua tshiab ● Kev hloov pauv tau zoo heev thiab kev sau npe raug |
| ● Lub zog tensile zoo heev, tiv thaiv kev sib tsoo thiab tiv thaiv kev cuam tshuam ● High flex-crack tsis kam ● Dav kub ntau yam hauv daim ntawv thov ● Zoo heev pob tshab thiab gloss | ● Muaj peev xwm nrog kev ruaj ntseg ntim zoo heev los siv rau cov khoom ntim hnyav, ntse thiab nruj. ● Tsawg distortion tom qab retort |
SHA tuaj yeem siv los tsim cov ntim qib siab hauv 12 xim, sealing dav ≤10cm thiab xav tau kev sau npe luam ntawv.Nws tsis yooj yim rau warp thiab curl tom qab 125 ℃ retorting.Nws raug pom zoo kom siv rau cov khoom ntim tsis hnyav nrog ib lub hnab ntim tsawg dua 2kg, piv txwv li, retort hnab thiab lub khob hau nrog cov qauv me me.
| Thickness / hli | Dav / hli | Kev kho mob | Retortability | Kev luam tawm |
| 15 | 300-2100 Nws | ib leeg/ob sab corona | ≤121 ℃ | ≤12 xim |
Daim ntawv ceeb toom: retortability thiab printability yog nyob ntawm cov neeg muas zaub 'lamination thiab printing ua mob.

Lub Me Dot/Shallow Net Poob
Cov ntawv luam tawm ploj lawm lossis tsis pom nyob rau hauv qhov ntiav ntiav ntawm cov qauv luam tawm (feem ntau tsawg dua 30% ntawm cov dot, loj hauv 50% ntawm cov dot tseem yuav tshwm sim).
Ua rau:
Ink fineness tsis txaus, ua rau qee qhov loj ntawm tus number case tsis tuaj yeem sau rau hauv lub network ntawm qhov ntiav;
● Ink concentration yog tuab heev, ua rau cov luam ntawv tsis zoo, tsim cov dot hollowing;
● Scraper siab loj heev uas ua rau me me ntawm number case, ink supply tsis sib npaug, ua rau poob ntawm cov dots me me;
● Kev siv cov kuab tshuaj kom qhuav sai heev, ua rau cov number case qhuav hauv qhov net thiab tsis tuaj yeem txuas rau zaj duab xis thaum lub sijhawm hloov cov txheej txheem ntawm qhov ntiav ntiav;
● Kev luam ntawv nrawm dhau qeeb, hauv cov number case kom qhuav hauv lub qhov net thaum lub sijhawm hloov pauv;
● Zaj duab xis nto yog ntxhib heev;tus cwj mem hauv qab yog tsis du.
Cov lus qhia ntsig txog:
✔ Xaiv fineness ≤15μm number case;
✔ Tsim nyog dilute number case viscosity;
✔ Tus kws kho mob yuav tsum tau hloov kho kom tsuas yog txhuam tus cwj mem, tsis txhob tso siab ntau dhau;
✔ Siv cov kuab tshuaj kom qhuav sai dua los kho qhov ziab kom ceev ntawm tus number case rau ntawm cov menyuam phaj;
✔ Sim kom ntseeg tau tias qhov ceev ntawm ntau tshaj 160m / min luam ntawv.
