Ifilimu yokutywina yePET/PE enomqobo ophezulu (esekwe kwi-EVOH)

Yintoni iHigh-Barrier PET/EVOH/PE Sealing Film?

Ifilimu yokutywina yePET/EVOH/PE enemiqobo ephezulu , eyaziwa ngokuba yifilimu yokugquma yeEVOH, ifilimu yetreyi ye-oxygen-barrier okanye ifilimu ye-MAP top-seal, sisixhobo sokupakisha esiguquguqukayo esineengqimba ezininzi esenzelwe iitreyi zokutya ezifuna ukuhanjiswa kweoksijini okuncitshisiweyo, ukutywinwa okuthembekileyo kunye nokugcinwa kwegesi okulawulwayo.

Ulwakhiwo oluqhelekileyo ludibanisa umaleko wangaphandle wePET okanye weBOPET, umaleko we-EVOH oxygen-barrier, umaleko we-tie okanye we-adhesive kunye nomaleko we-PE-based food-contact sealing.

Umaleko we-PET ubonelela ngokucaca, amandla okutsalwa, ukuqina, uzinzo olulinganayo kunye nokuprintwa. I-EVOH ibonelela ngomqobo oyintloko weoksijini kunye nevumba, ngelixa umaleko wangaphakathi osekelwe kwi-PE uvala ubushushu kumphezulu wokuvala we-PE ohambelanayo.

Imveliso eqhelekileyo yeHSQY yifilimu etywiniweyo enemiqobo ephezulu eyenzelwe ngokukodwa iitreyi zePET/PE ezihambelanayo, iitreyi zePET/EVOH/PE kunye nezinye izikhongozeli ezineflange yokutywina ebonakalisa umphezulu ofanelekileyo osekelwe kwiPE.

Ulwakhiwo lokugqibela lwefilimu, izinga lokudluliselwa kweoksijini, izinga lokudluliselwa komphunga wamanzi, amandla okutywina kunye nokusebenza kwexesha elide kufuneka kuchazwe kwaye kuvavanywe phantsi kweemeko zokusetyenziswa ezivunyiweyo.

Indlela Esebenza Ngayo Ulwakhiwo lwePET/EVOH/PE

Kutheni Usebenzisa i-EVOH kwiFilimu yokugquma iTray?

• Ukuncipha kokudluliselwa kweoksijini: I-EVOH inokunciphisa kakhulu ukungena kweoksijini xa ikhuselwe kwisakhiwo esenziwe ngokuchanekileyo esineengqimba ezininzi.

• Ukugcinwa kwegesi yeMAP: Isiciko esinomqobo ophezulu sinokunceda ukugcina i-carbon dioxide, i-nitrogen okanye ezinye iigesi zokupakisha ezikhethiweyo.

• Ukukhusela ivumba: I-EVOH inceda ekunciphiseni ukulahleka kwevumba elifunekayo kunye nokungena kwevumba langaphandle.

• Ulawulo lwe-oxidation: Ukuncipha kokuvezwa kwe-oksijini kunokucothisa ukutshintsha kombala, ukurhawuzelela, ukonakala kwencasa kunye nokuxinana kwezondlo zokutya ezifanelekileyo.

• Ukupakisha okucacileyo: Iileya zePET, EVOH kunye nePE ezicacileyo zivumela ukubonakala kwemveliso ngaphandle kokuxhomekeka kwifoyile yealuminiyam.

• Ukhuseleko loomatshini: I-PET okanye i-BOPET inika ukuqina, amandla okutsalwa kunye nokuphathwa kwewebhu okuzinzileyo.

• Ukuprinta ngokwezifiso: Umphezulu we-PET ongaphandle uxhasa uphawu, imiyalelo kunye nokulandeleka.

Umqobo ophezulu awuthethi ukuba ifilimu enye inokuqinisekisa ngokuzimeleyo ukhuseleko lokutya okanye ixesha lokuhlala eshelufini. Itreyi, isitywini, umxube wegesi, ucoceko kunye nekhonkco elibandayo nazo kufuneka zisebenze ngokuchanekileyo.
