Zikwalungele kakhulu iimveliso zetshizi kunye ne-deli ukugcina incasa kunye nobume ngokusika ukungena kweoksijini; ifilimu yazo eqinileyo inokupakisha nenyama ecutshungulwayo njengeepate. Iisosi ezingamanzi angangenwa zisenokusetyenziswa kwiingxowa ze-PA/PE ngenxa yeeleya eziqinileyo ezithintela ukuvuza ngelixa zigcina amavumba - zilungele ixesha elide lokugcina ixesha elibandayo! Ngamafutshane, iingxowa ze-PA/PE zilungele ukutya okunemiphetho engacwangciswanga okanye eqinileyo (amathambo/iitships zeetships zeenyama zeetships zeenyama), kufuneka ixesha elide lokufriji/lokukhenkceza - ligqibelele!

* Ezinye iindlela zokusetyenziswa: Iilamineti ze-PA/PE zinezinye iindlela ezininzi ngaphandle kokutya, ezifana nokupakisha kwezonyango kunye nezinto zoshishino. Ifilimu yazo enomngcipheko ophezulu ingacocwa kwaye ivalwe ukwenza izixhobo zonyango; ukupakisha nge-elektroniki kuyisebenzisela ukulawula umswakama ngelixa kongeza amandla oomatshini ngelixa iileya ezichasene nokuma okanye ezithintelayo zinokongezwa kwiibhodi zesekethe okanye ukupakisha ihardware. Ekugqibeleni, iingxowa ze-PA/PE zibonelela ngefilimu ethembekileyo yokusebenza enamandla aphezulu okuthintela kunye nokumelana nokubhoboza, okwenza ukuba ibe lolona khetho luphezulu kwiimfuno zokupakisha nge-vacuum ngokubanzi.

Iingxowa zokucoca umoya zePolyester/PE (PET/PE)

*Ulwakhiwo kunye neePropati: Iingxowa zePolyester/PE (ezidla ngokubizwa ngokuba ziingxowa zePET/PE okanye zePET-LDPE) zisebenzisa umaleko wePET wangaphandle onomaleko wangaphakathi wePE wokwakheka kwazo. I-PET inika imiqobo emihle yeekhemikhali, ubushushu kunye neoksijini kwaye amandla ayo aphezulu ngokuphindwe ka-5-10 kunamandla okutsalwa kwePE; ngaphezulu koko inokugcina iipropati zomzimba kumanqanaba obushushu abanzi, inika ezi ngxowa iingxowa ezibonakalayo ezinomthamo wokuthintela ophakathi (ezibonelela ngokucaca kunye nokumelana nokubhoboza okuphakathi; kodwa kwizinto ezinamachaphaza abukhali kakhulu kunokukhetha ukusebenzisa iileya zenylon).

* Izicelo: Iingxowa zokucoca i-PET/PE zilungele izinto ezifuna ukucaca kunye nokumelana neekhemikhali, ezifana nenyama ephekiweyo okanye etshayiweyo kunye nentlanzi efuna ukubonakala kwiingxaki zomgangatho wokupakisha. Ukuqina kwazo kwenza ukuba ubushushu buvalwe kwiimashini ezizenzekelayo; ngenxa yeempawu zokuqina kobushushu be-PET zisebenza kakuhle ngokulinganayo kwiindawo ezifrijini njengezo zikufutshane (umz. iimbotyi zekofu ezipakishwe nge-vacuum okanye iziqholo). Ngaphezu koko zihlala zisetyenziswa njengeefilimu eziphambili kwimigca yokupakisha i-vacuum ye-thermoforming (kusetyenziswa ii-webs zokwenza i-PA/EVOH/PE).

* Inqaku lobuchwephesha: Umqobo onamandla wePolyester kwiigesi unceda ukugcina ivumba elimnandi, kodwa iPET/PE ecocekileyo ayinayo umqobo onzulu weoksijini kunye nokuqina kokubhoboza kwePA/PE. Ngenxa yoko, iPET/PE inokuba yeyona ilungileyo kwiisuphu ezipakishwe nge-vacuum, iipowders, kunye nokutya okulula ngenxa yokwakhiwa kwayo okuthambileyo okanye okulula; i-carePac iqaphela ukuba iileya zepolyester okanye zenylon eziqinileyo zithintela ukubhoboza ngelixa zenza iPET/PE ifaneleke ukutywinwa nge-vacuum. Ngokwesiqhelo uninzi lweeprosesa zikhetha iPET/PE kwiimveliso ezihlala ixesha elide ezinee-textures ezifakwe i-embossed (ukuba zisebenzisa oomatshini bokufunxa) ukuze kuphuculwe amandla okutywina; ezi ngxowa zisebenza kakuhle kakhulu xa iiyunithi zegumbi (amanqanaba aphezulu e-vacuum anokwenzeka). Iingxowa zePET/PE ziyahambelana nazo zonke oomatshini bokupakisha nge-vacuum; iiyunithi zegumbi zibalasele ngakumbi ekuveliseni amanqanaba e-vacuum angaphezu kwezinye oomatshini bokupakisha nge-vacuum (amanqanaba aphezulu e-vacuum anokwenzeka).

Iifilimu Ezinemiqobo Emininzi (i-EVOH, i-PVDC njl.njl.)

Iifilimu ezinee-High-Barrier Multilayer (EVOH, PVDC njl.njl.) zibonelela ngokhuseleko olusebenzayo ekungeneni kwezinto ezingcolisayo eziyingozi kwindalo esingqongileyo.

*Iingxowa Ezisekelwe kwi-EVOH: Ukuze zihlale ixesha elide kwishelufu, ii-laminate ezinee-layer ezininzi ezibandakanya i-EVOH (ethylene-vinyl alcohol) barrier resin zibonelela ngexesha eliphezulu kwishelufu kunye nokuthintela ukulahleka kwemveliso. Izakhiwo eziqhelekileyo zezi laminate yi-PA/EVOH/PE okanye i-PE/EVOH/PE, apho i-EVOH core ibonelela ngesantya esiphantsi kakhulu sokuhambisa ioksijini ngelixa i-nylon okanye i-PET ibonelela ngamandla oomatshini kunye nokutywinwa - olu dibaniso luvelisa umqobo ophezulu wokugqibela: Iingxowa ze-EVOH zicothisa kakhulu ukufuduka kwe-oxidation kunye nokufuma ngelixa ngaxeshanye zongeza amandla oomatshini. Ngokweengxelo zeengcali, ezi laminate zinceda ukufikelela kwixesha elide kwishelufu efrijini okanye eqandisiweyo ngelixa ngaxeshanye zinciphisa ukulahleka kwemveliso xa kuthelekiswa nee-laminate ze-PA/PE.

*Iimpawu: Ifilimu ye-EVOH icacile kwaye iguquguquka, kodwa kwiingxowa ze-vacuum idla ngokufihlwa ziileya ezingabonakali kakuhle eziyisitha. Ezi ngxowa zigcina ukuthembeka kweseyi ngexesha lokuqandisa ngelixa i-PE ikhusela i-EVOH ekonakaleni komswakama; ukuqina kwayo kokubhoboza kwiileya ze-PA kudla ngokugqitha oko kwe-PA/PE elula ngaphandle kokubeka emngciphekweni amandla eseyi.

* Izicelo: Iingxowa zokucoca ezithintela kakhulu ze-EVOH ziyindlela efanelekileyo yokuthumela inyama entsha/eqandisiweyo kunye nokutya kwaselwandle okude kunye nokugcina ixesha elide. Iingxowa zokucoca ze-EVOH zikwayindlela entle yokukhusela ukutya okunexabiso eliphezulu okanye okunomoya-mpilo okufana netshizi, amandongomane, iziqhamo eziphelelwe ngamanzi okanye ukutya okulungisiweyo okuphezulu kunye neesosi ekulahlekelweni yioksijini okanye ekonakalisweni ngexesha lokuthuthwa okanye ukugcinwa. Ingxowa ye-EVOH kufuneka ihlale iqwalaselwa xa kufuneka kugcinwe umgangatho (umbala, incasa okanye ubunjani); ngamanye amazwi zisebenzise nanini na xa iimveliso ze-sous vide zifuna iimeko ezifanelekileyo zokuhamba okanye iimfuno zokugcina izinto zexesha elide!

*Eminye Imiqobo: Iifilimu ezigqunywe ngePVDC ezisetyenziswa kwiingxowa zetshizi okanye zenyama ezicociweyo zinika ukungenwa kwe-O2 ephantsi; nangona kunjalo, imiba yokulawula kunye nokucubungula iye yanciphisa ukusetyenziswa kwazo. Iifilimu ezenziwe ngesinyithi ze-vacuum (i-PET okanye i-PA egqunywe nge-aluminium) nazo ziyawuphucula umsebenzi wokuthintela (jonga icandelo elilandelayo).

Iingxowa zokucoca umoya ze-aluminium foil (zenziwe ngesinyithi)

Ukupakishwa kwekofu, iti okanye iziqholo nge-vacuum kudla ngokubandakanya iingxowa ezine-aluminium laminated ukuze kukhuselwe kakuhle. Iileya zefoyile ye-aluminium ngaphakathi kwingxowa zenza umqobo osebenzayo ekukhanyeni, kwi-oksijini nakwimfucuza - zilungele ukugcina ikofu itsha ixesha elide! Iingxowa zefoyile-vacuum eziqhelekileyo zineeleya ezintathu ezisebenza ukuvimba ukukhanya, ioksijini kunye nokufuma: I-PET/AL/PE okanye i-PA/AL/PE - ifilimu ye-PET yangaphandle inika ukumelana nokubhoboza ngelixa amandla okubhoboza ngelixa i-AL foil ivimba igesi kunye nokukhanya ngelixa i-PE iqinisekisa ukuvalwa kobushushu okucocekileyo - isiphumo kukuba akukho moya okanye ukufuma okunokudlula!

* Iimpawu: Iingxowa ze-aluminium-laminate zinokuba lukhuni kodwa zibe nokumila; zibonisa ubushushu nokukhanya, zikhusela kwimitha ye-UV kunye notshintsho lobushushu, ngelixa zihlala zingacacanga ukuze umxholo uhlale ufihliwe ngelixa iimveliso zihlala zomile kwaye zingangcoliswanga. Ngaphezu koko, iingxowa ze-aluminium laminate zisebenza kakuhle ngokulinganayo kwiindawo ezibandayo okanye kwiindawo ezishushu zokuzalisa (qaphela ukuba iingxowa zefoyile azinakukhuselwa kwi-oven ngaphandle konyango olukhethekileyo).

* Ukusetyenziswa: Iingxowa zefoyile zingasetyenziselwa ukukhusela izinto ezixabisa kakhulu okanye ezibola kakhulu ezifana nekofu kunye neti (ukugcina ivumba elimnandi kunye nokutsha), ukutya okomisiweyo ngomgubo okanye okuqandisiweyo, amandongomane, kunye nemifuno. Kwiindawo zokutya, iingxowa zesous vide/boil-in-bag zihlala zisebenzisa ifoyile; zilungele amayeza/iivithamini/izongezo/iivithamini njl. Ukongeza, amagqabi eti afakwe kwi-vacuum adla ngokugcina incasa yawo ixesha elide xa egcinwe kwi-foil laminate xa kuthelekiswa neplastiki (umzekelo) oboniswe apha ngumzekelo nje!

* Ukuhambelana koomatshini: Iingxowa zefoyile ye-aluminiyam zihlala zigudile kwaye ngamanye amaxesha zivalwa kusetyenziswa oomatshini abanzima, nto leyo eyenza oomatshini bokupakisha abangaphandle be-DJVAC bafaneleke ukuphatha ezi ngxowa ngaphandle kwengxaki.

Izicelo zeMizi-mveliso kunye nezoLondolozo lweeNkcukacha.

Iingxowa zokucoca umoya ezinemiqobo ephezulu zibonelela ngezinto ezininzi ngaphandle kokutya nje kuphela:
