    Iifilimu ze-PVDC High-Barrier Shrink

    Isisombululo soBuchule sokuPakisha inyama entsha

    Njengoko iimfuno zehlabathi zokhuseleko lokutya kunye nexesha elide lokugcinwa kokutya lisanda, ukusebenza kwezixhobo zokupakisha ezibandayo kuye kwaba yinto ephambili kubavelisi bokutya kunye nabathengisi. Phakathi kwezinto ezahlukeneyo, i-PVDC (i-polyvinylidene chloride) ivelele ngenxa yeempawu zayo ezibalaseleyo zokuthintela iigesi kunye nokufuma, okwenza ukuba ibe sisisombululo esifanelekileyo sokupakisha iimveliso ezibolayo ezifana nenyama entsha, iinkukhu kunye neentlanzi zaselwandle.

    iinkcukacha zemveliso

    Kutheni Ufanele Ukhethe iPVDC Kwimpahla Entsha Yokupakisha?

    Ukutya okutsha kufuna iimeko zokugcina ezichanekileyo kunye nokupakishwa okuphezulu ukugcina umgangatho kunye nokhuseleko. Nangona i-EVOH ikwaziwa ngokusebenza kwayo okuphezulu kokuthintelwa, iimpawu zayo zokuthintelwa komoya-mpilo ziyawohloka kakhulu kwiimeko ezinomswakama ophezulu, nto leyo eyenza i-PVDC ibe lukhetho oluzinzileyo ngakumbi lokupakishwa kwenyama efrijini. Iifilimu ze-PVDC zibonelela ngezi zibonelelo zilandelayo:
    • 01

      Isithintelo seOksijini esiBalaseleyo

      Ibambezela ngokufanelekileyo i-oxidation yamafutha kunye nokukhula kweentsholongwane, inciphisa umngcipheko wokonakala.

    • 02

      Umqobo oMkhulu wokufuma

      Ithintela ukulahleka okanye ukungena kwamanzi, igcina ubume bemveliso, umbala, kunye nobunzima bayo.

    • 03

      Ukuncipha okuphezulu

      Iqinisekisa ukuhambelana okuqinileyo nemigangatho yemveliso, iphucula ukuthembeka kokupakishwa kunye nomtsalane obonakalayo.

    • 04

      Ukuhambelana kweCold Chain

      Igcina ukusebenza kwayo rhoqo kwiindawo ezibandayo (0–4°C), nto leyo ibalulekileyo ekugcineni inyama entsha.

    Inkqubo yoLwakhiwo oluDibeneyo kunye nolweMveliso

    Iingxowa zethu zePVDC ezinciphayo ezinemiqobo ephezulu ziveliswa kusetyenziswa ubuchwepheshe obuphambili befilimu eqhumayo eneeleya ezintlanu kunye nolwakhiwo olulandelayo: PE / EVA / PVDC / EVA / PE

    Iimpawu eziphambili ziquka:

    • Uyilo lweLayer oluLungileyo

      Iileya ze-PE/EVA zangaphakathi nezangaphandle ziqinisekisa ukusebenza kakuhle kokutywina kunye nokuguquguquka; ileya ye-PVDC ephakathi inika ukusebenza okuqinileyo kokuthintela.

    • Ubukhulu obunokwenziwa ngokwezifiso

      Ifumaneka ngobubanzi obuqala kwi-165 mm ukuya kwi-500 mm, ubude bayo buhambelana neemfuno zabathengi.

    • Ukugxila kuZinzo

      Silinganisela ngononophelo umxholo we-PVDC ukuqinisekisa ukusebenza kakuhle kunye noxanduva lokusingqongileyo, sithobela imigangatho yemithetho yehlabathi.

    Ukubaluleka Kweemeko Ezifanelekileyo Zokugcina Izinto

    Ubushushu obuphakathi kwe-0–4°C buthathwa njengobushushu obufanelekileyo bokugcina inyama entsha. Ngaphakathi kolu luhlu:

    ● Ithintela ukwakheka kwe-Ice Crystal: Amaqondo obushushu angaphantsi kwe-0°C abangela iikristale zomkhenkce ezonakalisa udonga lweeseli kwaye zonakalise ubume benyama.
    ● Ithintela ukukhula kweebhaktheriya: Izinga lokukhula kwebhaktheriya licotha kakhulu kolu luhlu. Xa zidityaniswe nokukhuselwa kwemiqobo yeengxowa zePVDC ezinciphayo, oku kunceda ukwandisa ubomi beshelufu kakhulu.

    Ulindelo lobomi beshelufu usebenzisa iphakheji yefilimu yokunciphisa yePVDC: Inyama yehagu: Ukuya kuthi ga kwiintsuku ezingama-45 / Igusha: iintsuku ezingama-60–90 / Inyama yenkomo: iintsuku ezingama-90–120

    Ulawulo Lomgangatho: Ukusuka Kwipakethe ukuya Kwishelufu

    Ukuqinisekisa ukusebenza kakuhle kwenkqubo yokupakisha kunye nokhuseleko lokutya, sicebisa ezi ndlela zilandelayo zokulawula iintsholongwane:

    ● Uvavanyo lokuqala lweeMicrobial: Yenza uvavanyo lokubalwa kwe-colony iyonke kunye ne-E. coli ngaphambi kokuyipakisha ukuqinisekisa amanqanaba asisiseko amkelekileyo.
    ● Uvavanyo Lokuphela Kobomi: Vavanya kwakhona iiparameter ezifanayo ekupheleni kwexesha lokugcina (umz., usuku lwe-120) ukuqinisekisa uzinzo kunye nokhuseleko.

    Ukulawula umthwalo wokuqala weentsholongwane kubalulekile. Xa zidityaniswe neempawu zomqobo eziphezulu zePVDC, le ndlela ivumela ukugcinwa okuthembekileyo ixesha elide.

    Dibana no

    Njengomvelisi onolwazi olunzulu kwiifilimu zokupakisha ukutya ezinemiqobo emininzi, sizibophelele ekunikezeni izisombululo zokupakisha ezinokuthenjwa nezisebenza kakuhle kwiindlela zokubonelela ngokutya kwihlabathi liphela. Iifilimu zokunciphisa ukutya ezinemiqobo emininzi yePVDC zibonelela ngesisombululo esisebenzayo nesiqinisekisiweyo sokwandisa ixesha lokugcinwa kunye nokugcina umgangatho wemveliso kwiindawo zokupakisha inyama ezifrijini.
