Amathreyi/Ishidi le-EVOH Barrier

I-EVOH, PA barrier multilayer ifilimu yabalingisi ehlanganisiwe

I-EVOH, ifilimu ye-PA barrier multilayer co-extruded cast

Nge-EVOH, i-PA njengento ewumongo ye-multi-layer coextrusion cast ifilimu yokuvimbela (EBF)

Izakhiwo ezinhle kakhulu zokuvimbela umoya-mpilo, umgoqo we-oxygen ukungena;

Isithiyo esihle kakhulu sephunga, ukuvuza kwesithiyo kugcina ukunambitheka komkhiqizo koqobo;

Excellent stretch forming uniforms, esebenza kahle futhi ngempumelelo amanzi Ukuvinjwa ukugcina umswakama ikhiyiwe inyama ezipakishiwe;

Ukumelana nokubhoboza okuhle nokusebenza okuthembekile kokuvalwa, qinisekisa ukuthi ukupakishwa kwe-vacuum noma isimo sokuvuvukala;

Ukucaca okuphezulu, ukubukeka kwefilimu ecwebezelayo, kuthuthukisa ukugqama kokupakishwa komkhiqizo kanye nokugcwala;

Ifanele i-high-temperature pasteurization noma inzalo (isakhiwo esibunjiwe se-PP).

Isicelo

Ngokusebenzisa izinto ezinhle kakhulu zokuvimbela izingqimba ze-EVOH ne-PA, zingavimbela ngempumelelo izinto zokupakisha ezintweni eziguquguqukayo nephunga kanye nesithiyo somswakama ngaphandle kokungcoliswa kokupakisha, futhi ekugcineni zisebenzele ukuqinisekisa ikhwalithi yomkhiqizo nokwandisa ishalofu elibunjwe ngokuqondile izidingo zokupakisha eziphakeme, ezifanele inyama, izinkukhu, izilwane zasolwandle, ushizi nokunye ukupakisha ukudla.

Imikhiqizo esebenzayo

Imikhiqizo yenyama eshisa kakhulu futhi ephansi, imikhiqizo yobisi, imishini yezokwelapha kanye nokupakishwa.

Isakhiwo esiyisisekelo kanye nezimo zohlelo lokusebenza

I-PA / EVOH / PA / PE ifilimu ye-thermoformed lid ngezansi ngezansi .110 ° C / 30 imizuzu ukuvala inzalo

I-PA / EVOH / PA / PP isivalo se-thermoformed ngemva kokuphela kwefilimu .121 ° C / 30 imizuzu yokuvala inzalo

I-PA / EVOH / PA / PE inhlanganisela yendawo yonke, isikhwama, i-substrate yokuphrinta

I-PA / EVOH / PA / EVA impahla enohlobo oludabula kalula, emboza ifilimu yesisekelo sefilimu. Isetshenziswa ekudleni okuhlukahlukene

I-PA / EVOH / PA / PE izinto ezikhethekile zokupakisha isikhumba, inyama eluhlaza, ukupakishwa kukashizi 

Isetshenziswa ekugcineni kwefilimu yokupakisha okuzenzakalelayo kwe-"FFS", ifilimu ekhavayo, inqubo yokupakisha yesikhwama esinenyama ephansi ngokuqondile, kuzo zonke izinhlobo zemikhiqizo ebucayi yokudla njengenyama, ikhofi nokunye ukupakisha kwe-vacuum

Okwe-PP, PE, PS kanye nelinye ifilimu lekhava yethreyi yokupakisha (elingadalula kalula)
