Makanema Okhala ndi Zopinga Zambiri

Kodi Mafilimu Opangidwa ndi High Barrier Composite ndi Chiyani?

Makanema okhala ndi zotchinga zazikulu ndi makanema okhala ndi laminated okhala ndi zigawo zambiri omwe amapangidwa kuti ateteze zomwe zili m'matumba ku mpweya, chinyezi, fungo, kuwala, ndi zinthu zina zakunja.
Makanema awa nthawi zambiri amaphatikiza zinthu monga PET , Nayiloni, EVOH, zojambulazo za Aluminium, ndi PE/CPP kuti akwaniritse bwino kwambiri zotchinga.
Amagwiritsidwa ntchito kwambiri popanga chakudya, mankhwala, ndi mafakitale zomwe zimafuna nthawi yayitali yosungiramo zinthu komanso kukhulupirika kwa zinthuzo.

Ndi zipangizo ziti zomwe nthawi zambiri zimagwiritsidwa ntchito m'mafilimu oteteza kwambiri?

Kapangidwe ka zinthu zomwe zimagwiritsidwa ntchito ndi izi:
• PET /AL/PE (Filimu yopangidwa ndi foil ya Aluminium)
• PET /NY/PE
• BOPP/EVOH/CPP
• Nayiloni/PE yokhala ndi gawo lapakati la EVOH
• Filimu yopangidwa ndi zitsulo PET kapena BOPP.
Kuphatikiza kwamitundu yambiri kumeneku kumatsimikizira kukana kwabwino kwa mpweya ndi chinyezi pamene kumasunga kusinthasintha ndi kutsekeka.

Kodi ubwino waukulu wogwiritsa ntchito mafilimu opangidwa ndi zinthu zoteteza kwambiri ndi uti?

Makanema okhala ndi zotchinga zazikulu amapereka zabwino izi:
• Makhalidwe abwino kwambiri otchinga mpweya ndi chinyezi
• Kukhalitsa nthawi yayitali mu shelufu ya chinthucho komanso kusunga zatsopano
• Fungo labwino kwambiri, kukoma, ndi chitetezo cha UV
• Yoyenera kupakidwa mu vacuum ndi kupakidwa mumlengalenga wosinthidwa ( MAP )
• Malo osindikizidwa kuti asindikizidwe ndi kulembedwa
• Mphamvu yamphamvu yamakina komanso kukana kubowoka

Ndi mapulogalamu ati omwe amafunikira mafilimu oteteza kwambiri?

Makanema opangidwa ndi zitsulo zotchinga kwambiri amagwiritsidwa ntchito kwambiri mu:
• Nyama, masoseji, ndi nsomba zophikidwa mu vacuum
• Khofi, tiyi, ndi ma CD a chakudya chopepuka
• Mankhwala ndi zipangizo zachipatala
• Tchizi, mkaka, ndi ma CD a chakudya cha ufa
• Chakudya cha ziweto ndi zowonjezera zakudya
• Zipangizo zamagetsi ndi mafakitale zomwe zimakhudzidwa ndi chinyezi.

Kodi mafilimu okhala ndi mipanda yolimba amafanana bwanji ndi mafilimu wamba?

Makanema opangidwa ndi zinthu zokhazikika angapereke chitetezo choyambira koma sayenera kugwiritsidwa ntchito pazinthu zomwe zimafunika kusungidwa kwa nthawi yayitali.
Makanema okhala ndi zotchinga zazikulu amakhala ndi zigawo zapadera monga zojambula za aluminiyamu, EVOH, kapena zitsulo PET kuti achepetse kwambiri kuchuluka kwa mpweya ndi chinyezi (OTR ndi MVTR).
Amateteza bwino zinthu, makamaka m'malo osungira kapena oyendera kwambiri.

Kodi mafilimu okhala ndi zotchinga zazikulu ndi oyenera kupakidwa vacuum ndi MAP ?

Inde, mafilimu okhala ndi mipanda yolimba amagwiritsidwa ntchito kwambiri m'matumba a vacuum ndi m'mabokosi osinthidwa amlengalenga ( MAP ).
Kuchepa kwawo kwa mpweya kumathandiza kuchotsa mpweya ndikusunga nayitrogeni kapena CO₂, kukulitsa kutsitsimuka ndikuletsa kukula kwa tizilombo toyambitsa matenda.
Amagwiritsidwa ntchito kwambiri pokonza nyama, kuyika tchizi, komanso kugwiritsa ntchito chakudya chokonzeka kudyedwa.

Kodi mafilimu okhala ndi mipanda yolimba kwambiri akhoza kutsekedwa, kusindikizidwa, kapena kusinthidwa kukhala zinthu zina?

Inde. Mafilimu awa akhoza kukhala otsekedwa ndi kutentha kapena ozizira, kutengera gawo lotsekedwa (PE, CPP, EVA, ndi zina zotero).
Amagwirizana ndi gravure, flexo, ndi kusindikiza kwa digito.
Zinthu zina zomwe mungasankhe ndi monga ma notches osavuta kung'amba, zipper zotsekedwanso, anti-fog coating, ndi laser scoring.
Kukhuthala, milingo yotchinga, ndi mankhwala a pamwamba onse akhoza kusinthidwa kuti agwirizane ndi zosowa zinazake zolongedza.

Kodi mafilimu awa ndi otetezeka pa chakudya ndipo akutsatira malamulo?

Inde, mafilimu opangidwa ndi zinthu zoteteza chakudya amapangidwa motsatira miyezo ya FDA, EU, ndi GB.
Ndi otetezeka kuti agwirizane mwachindunji ndi chakudya ndi zakumwa, kuphatikizapo kugwiritsa ntchito mufiriji, mufiriji, komanso mu njira zobwezerezedwanso.
Zikalata zowunikira (COA), malipoti oyesa kusamuka, ndi zambiri pepala zakuthupi zitha kuperekedwa mukapempha.

Kodi ndi makulidwe otani omwe alipo pa mafilimu okhala ndi zotchinga zambiri?

Kukhuthala kwake nthawi zambiri kumakhala pakati pa ma microns 50 mpaka ma microns 180 kutengera kapangidwe kake ndi momwe amagwiritsidwira ntchito.
Mafilimu opangidwa ndi vacuum nthawi zambiri amakhala ma microns 70–150, pomwe ma laminates a chakudya chopepuka amatha kukhala opyapyala (ma microns 20–60).
Kapangidwe kake kakhoza kupangidwa kutengera kukhudzidwa kwa zinthu ndi zofunikira pakugwira ntchito ndi makina.

Kodi mafilimu okhala ndi mipanda yolimba amatha kubwezeretsedwanso kapena ndi abwino kwa chilengedwe?

Makanema otchinga zinthu zambiri achikhalidwe ndi ovuta kuwabwezeretsanso.
Komabe, makanema otchinga zinthu zobwezerezedwanso (monga, onse-PE kapena onse-PP) akupezeka kwambiri, omwe amapereka njira zosungira zinthu zokhazikika.
Opanga ena amaperekanso makanema otchinga zinthu pogwiritsa ntchito zinthu zosungunuka monga PLA kapena cellulose.
Ndikofunikira kufananiza zosowa za magwiridwe antchito ndi zolinga zokhazikika pakusankha filimu.
