Amathreyi angu PET/PE Ifilimu Lokufaka uphawu lokupakisha ka- PET/PE

Iyini Ifilimu Yokuvala Enezivikelo Eziphakeme PET/EVOH/PE ?

Ifilimu yokuvala enezivikelo eziphezulu PET/EVOH/PE , eyaziwa nangokuthi ifilimu yokumboza i-EVOH, ifilimu ye-oxygen-barrier ithileyi noma ifilimu ye-top-seal MAP , iyinto yokupakisha eguquguqukayo enezingqimba eziningi eyenzelwe ukudla amathreyi okudinga ukudluliswa kwe-oxygen okuncishisiwe, ukuvalwa okuthembekile kanye nokugcinwa kwegesi okulawulwayo.

Isakhiwo esijwayelekile sihlanganisa ungqimba lwangaphandle PET noma BOPET , ungqimba lwe-EVOH-oxygen-barrier, izendlalelo ze-tie noma ze-adhesive kanye nesendlalelo sokuvala esisekelwe ku-PE-based food-contact.

Isendlalelo se- PET sinikeza ukucaca, amandla okuthamba, ukuqina, ukuzinza kobukhulu kanye nokuphrinta kalula. I-EVOH inikeza isithiyo esiyinhloko se-oxygen kanye nephunga, kuyilapho isendlalelo sangaphakathi esisekelwe ku-PE sivala ukushisa endaweni yokuvala ye-PE ehambisanayo.

Umkhiqizo ojwayelekile wamanje we-HSQY uyifilimu yokuvala enesivalo esiphezulu ehloselwe ikakhulukazi i PET/PE amathreyi ehambisanayo, PET/EVOH/PE amathreyi nezinye izitsha ezine-flange yokuvala eveza indawo efanelekile esekelwe ku-PE.

Isakhiwo sokugcina sefilimu, izinga lokudluliswa komoya-mpilo, izinga lokudluliswa komoya-mpilo phakathi kwamanzi nomhwamuko, amandla okuvala uphawu kanye nokusebenza kwesikhathi sokulinda kumele kuchazwe futhi kuhlolwe ngaphansi kwezimo zokusetshenziswa okuvunyelwene ngazo.

Indlela Isakhiwo se- PET/EVOH/PE Esisebenza Ngayo

Kungani Kufanele Usebenzise I-EVOH Kufilimu Yokumboza Ithreyi?

• Ukwehliswa kokudluliswa komoya-mpilo: I-EVOH inganciphisa kakhulu ukungena komoya-mpilo uma ivikelwe ngaphakathi kwesakhiwo esiklanywe kahle esinezingqimba eziningi.

• MAP ukugcinwa kwegesi: Isivalo esinomkhawulo ophezulu singasiza ekugcineni i-carbon dioxide, i-nitrogen noma amanye amagesi okupakisha akhethiwe.

• Ukuvikelwa kwephunga: I-EVOH isiza ukunciphisa ukulahleka kwephunga elifiselekayo kanye nokungena kwephunga langaphandle.

• Ukulawulwa kokukhishwa kwe-oksijini: Ukwehla kokuvezwa kwe-oksijini kunganciphisa ukushintsha kombala, ukusha, ukonakala kokunambitheka kanye nokukhishwa kwezakhamzimba ekudleni okufanele.

• Ukupakishwa okusobala: Izendlalelo ezicacile PET , EVOH kanye ne-PE zivumela ukubonakala komkhiqizo ngaphandle kokuthembela ku-aluminium foil.

• Ukuvikelwa kwemishini: PET noma BOPET kunikeza ukuqina, amandla okunamathela kanye nokuphathwa kwewebhu okuzinzile.

• Ukuphrinta ngokwezifiso: Indawo yangaphandle PET isekela ukumaka, imiyalelo kanye nokulandelela.

Isithiyo esiphakeme akusho ukuthi ifilimu eyodwa ingaqinisekisa ukuphepha kokudla noma isikhathi sokuphelelwa yisikhathi. I ithileyi , uphawu, ingxube yegesi, inhlanzeko kanye nochungechunge olubandayo nakho kumele kusebenze kahle.

Ukusebenza Kokuvinjelwa Kwe-EVOH Nomswakama

I-EVOH iyinto ephumelelayo yokuvimbela umoya-mpilo, kodwa ukusebenza kwayo kokuvimbela igesi kuyazwela umswakama kanye nomswakama ohlobene.

Ngenxa yalesi sizathu, i-EVOH ivame ukufakwa phakathi kwe-PE noma ezinye izendlalelo ezingamelani nomswakama esikhundleni sokusetshenziswa njengendawo yokuxhumana nokudla eveziwe noma indawo engaphandle.

Umphumela we-OTR olinganiswe ngaphansi kwezimo zelebhu eyomile akufanele wethulwe ngokuzenzakalelayo njengokusebenza okuqinisekisiwe kwephakheji yokudla okubandayo okumanzi.

Noma yiliphi izinga lokudluliswa komoya-mpilo elishiwo kufanele likhombe:

• Izinga lokuhlola

• Izinga lokushisa lokuhlola

• Umswakama ohlobene ohlangothini ngalunye lwefilimu

• Ubukhulu befilimu

• Ukuqondiswa kwefilimu

• Amayunithi okuhlola

• Kungakhathaliseki ukuthi inani lisebenza efilimini noma ephaketheni eliphelele

Imininingwane Yefilimu Ephakeme PET/EVOH/PE

Ithebula elilandelayo lifingqa umkhiqizo wamanje ojwayelekile we-HSQY onesivalo esikhulu sokukhiya. Amanani okugcina aqinisekisiwe kufanele avele kudatha yobuchwepheshe evunyiwe impahla yeshidi kanye nencazelo yokuthenga.

Umkhiqizo wamanje uyizinga lokuvala elikhiyiwe. Amazinga okuxebuka kalula, okuvimbela inkungu, okushisa okuphansi kanye nokushisa adinga izakhiwo ezihlukene futhi akufanele kuthathwe ngokwencazelo ejwayelekile.

Ukuqonda i-OTR, i-WVTR kanye ne-Whole-Pack Barrier

Umphumela we-OTR wefilimu kuphela awumeleli ukungena komoya-mpilo kwephakheji ephelele ithileyi .

Ifilimu Yokuvala I-High-Barrier Lock

Umkhiqizo wamanje we-HSQY PET/EVOH/PE usebenzisa isakhiwo se-lock-seal noma se-weld-seal.

Ifilimu yokuvala ikhiye ikhethwa lapho ukuphepha kwephakeji, ukugcinwa kwegesi, ukumelana nokuvuza kanye nokuqina kwezokuthutha kubaluleke kakhulu kunokuvuleka kwabathengi.

Iphakheji yokuvala ikhiye ingadinga ukunqunywa, ukubhobozwa noma ukudatshulwa ukuze kufinyelelwe ekudleni. Akufanele ithengiswe njengokuxebuka okulula ngaphandle kokuthi kuhlolwe i-sealant ehlutshuliwe ethuthukisiwe.

Buyekeza okuhlobene            ifilimu yokumboza enezivikelo eziphezulu PET/EVOH/PE    .

Ifilimu Enezithiyo Ezinkulu Ezenziwe Kalula

Ifilimu evimbela kakhulu ehlubuka kalula ihlanganisa ukuvikelwa komoya-mpilo nokuvulwa kwabathengi okulawulwayo.

Inguqulo ephumelelayo yokuhluza kalula kufanele ihlinzeke:
