Sequential BOPA Nemativi Maviri Corona Yakarapwa
OA2 ndiwo ese ari maviri mativi corona akabatwa sequential BOPA ine yakanakisa yakazara zvivakwa.Iyo inowanzo shandiswa seyepakati layer uye pamusoro pekuita senge coating uye metallization application.
| Features | Benefits |
| ✦ Zvakanaka flex crack resistance; ✦ Simba rakanaka uye puncture / kukanganisa kuramba | ✦ Inokodzera zvakasiyana-siyana zvekurongedza; ✦ Inokwanisa kurongedza zvinorema, zvakapinza kana zvakaomarara zvigadzirwa zvine yakanakisa kurongedza kuchengetedza |
| ✦ High gas barrier; ✦ Yakanakisa kunyorera pakupisa uye kwakadzika tembiricha; ✦ Ukobvu hwakasiyana; ✦ Kujeka kwakanaka; ✦ Kugadzirisa | ✦ Wedzera hupenyu hwesherufu; ✦ Inokodzera chikafu chakaomeswa nechando uye pasteurization / kubikira application; ✦ Hukobvu hwakarongedzerwa kune akasiyana simba zvinodiwa-mutengo unoshanda; ✦ Zvirinani zvekunzwa kunaka; ✦ Zvirinani kusangana nevatengi zvinodiwa |
| Hukobvu/μm | Upamhi/mm | Kurapa | Retortability | Kudhinda |
| 10 - 30 | 300-2100 | Single side corona | ≤100℃ | ≤6 mavara (anokurudzirwa) |
Cherechedza: retortability uye printability zvinoenderana nevatengi 'lamination uye kudhinda kugadzirisa mamiriro.

OA2 inogona kushandiswa kugadzira inochinjika yekurongedza kudhinda mukati memavara matatu (kusanganisira 3 mavara), kuvhara upamhi.≤1cm uye pasina chinodiwa pakunyoresa kudhinda, senge bhegi risina chinhu, vacuum freeze bag, bhegi remvura chigadzirwa, uye vacuum compression bag.Iwo chaiwo mashandisirwo senge pazasi, bhegi remukati renzungu (walnuts, mhodzi dzesunflower, nezvimwewo) uye bhegi remukati rezvigadzirwa zvenyama (Texas grilled huku, steak, nezvimwewo), zvemagetsi shielding kurongedza, kurongedza kwemvura, sewaini, chinwiwa, muto. , bhegi rekuchengetera mukaka waamai, bhegi rekuchengetera mvura, ginseng muto wehuku, bhegi remafuta, bhegi rebhokisi, chikafu chemuchadenga, bhegi rehove mhenyu, kutonhora uye nyama nyowani, hove dzegungwa, halogen kukiya kutsva kurongedza, nezvimwe.
Kupinza Kwemavara
Zviri nyore kuitika muNY/PE(CPP) chimiro.Muvara wemhete yekubikira yakanyanya kutsvuka uye yepepuru panguva yekubika.Kana iyo yekunze layer ikashandurwa kuita PET mhete BOPP, ipapo kupinda kwemavara kuri nyore kuitika.
Zvinokonzera:
Tembiricha uye humidity (mvura) zvinhu zviviri zvakakosha zvinokonzeresa kupinda kwemavara.
● Nylon resin inonzi thermoplastic polymer kubva ku semi-crystalline kusvika kune amorphous.Kana tembiricha ichiwedzera, kuchinja kukuru kwegadziriro pakati pemamorekuru, ndiko kukura kunoita kuti pigment ifambe.
● Kudzivirira kwemvura kwenylon kwakashata, mukati mekubika, mamorekuru emvura ari munylon mukati nekunze, achisuka zvikamu zvepigment mukudhinda inki.
● Mimwe pigment inonyungudika mumvura.
Mazano anoenderana:
✔ Shandisa ingi mbiri dzemvura yepolyurethane.
✔ Wedzera imwe inorapa iyo inki inopindika zvakare.
