Mafirimu Ane Zvipingamupinyi Zvakakura

Chii chinonzi High Barrier Composite Films?

Mafirimu ane mipendero mikuru akagadzirwa nemachira akawanda akagadzirirwa kuchengetedza zviri mukati kubva kumhepo, hunyoro, hwema, chiedza, nezvimwe zvinhu zvekunze.
Mafirimu aya anowanzo sanganisa zvinhu zvakaita sePET, Nylon, EVOH, Aluminum foil, uye PE/CPP kuti aite basa rakanaka remipendero.
Anoshandiswa zvakanyanya mukugadzira chikafu, mishonga, uye maindasitiri izvo zvinoda kugara kwenguva refu uye kuvimbika kwechigadzirwa.

Ndezvipi zvinhu zvinowanzo shandiswa mumafirimu ane mipendero yakakwira?

Zvivakwa zvakajairika zvinosanganisira:
• PET/AL/PE (Aluminum foil composite film)
• PET/NY/PE
• BOPP/EVOH/CPP
• Nayiloni/PE ine EVOH core layer
• Metallized PET kana BOPP composite film
Iyi misanganiswa ine zvidimbu zvakawanda inoita kuti oxygen nemwando zvirambe zvakanaka uku ichichengetedza kuchinjika uye kuvharika.

Ndezvipi zvakanakira kushandisa mafirimu ane mipendero yakawanda?

Mafirimu ane zvipingamupinyi zvakakura anopa zvakanakira zvinotevera:
• Hunhu hwakanaka hwezvipingamupinyi zveokisijeni nehunyoro
• Nguva refu yekushanda kwechigadzirwa uye kuchengetedza kutsva
• Kunhuhwirira kwakanaka, kunaka, uye dziviriro yeUV
• Yakakodzera kurongedza vacuum uye kurongedza mhepo yakagadziriswa (MAP)
• Nzvimbo dzinodhindwa dzekunyora nekunyora mazita
• Simba rakasimba remuchina uye kuramba kubhoorwa

Ndezvipi zvinoshandiswa zvinoda mafirimu ane mipendero yakakura?

Mafirimu ane mitsetse mikuru anoshandiswa zvakanyanya mu:
• Nyama, masoseji, uye hove dzakaputirwa ne vacuum
• Kofi, tii, uye chikafu chekudya chemazuva ano
• Mishonga nezvishandiso zvekurapa
• Cheese, mukaka, uye chikafu cheupfu
• Chikafu chemhuka nezvinovaka muviri
• Zvigadzirwa zvemagetsi uye zveindasitiri zvinonzwa hunyoro

Mafirimu ane mipendero yepamusoro anoenzaniswa sei nemafirimu akajairwa?

Mafirimu akajairika anogona kupa dziviriro huru asi haana kukodzera zvigadzirwa zvinoda kuchengetedzwa kwenguva refu.
Mafirimu ane zvipingamupinyi zvakakura anosanganisira machira akasarudzika senge aruminiyamu foil, EVOH, kana PET yakagadzirwa nesimbi kuti aderedze zvakanyanya huwandu hwemhepo nehunyoro (OTR neMVTR).
Anovimbisa dziviriro iri nani yechigadzirwa, kunyanya mumamiriro ekuchengetedza akaomarara kana ekutakurwa.

Mafirimu ane mipendero yakareba akakodzera here kurongedza vacuum uye MAP?

Ehe, mafirimu ane mipendero yakawanda anowanzo shandiswa mumapochi evacuum uye mumodified atmosphere packaging (MAP).
Kupinda kwawo kwakaderera kunobatsira kubvisa okisijeni uye kuchengetedza nitrogen kana CO₂, zvichiita kuti hutachiona huwedzere kutsva uye kudzivirira kukura kwehutachiona.
Anoshandiswa zvakanyanya mukugadzira nyama, kurongedza chizi, uye kushandiswa kwekudya kwakagadzirira kudyiwa.

Mafirimu ane mipendero yakareba anogona kuvharwa, kudhindwa, kana kugadziriswa here?

Zvechokwadi. Mafirimu aya anogona kuvharwa nekupisa kana kuvharwa nechando, zvichienderana nechikamu chekuvharwa (PE, CPP, EVA, nezvimwewo).
Anoenderana negravure, flexo, uye digital printing.
Zvimwe zvinhu zvinosanganisira ma notches anotsemuka nyore nyore, zippers dzinovharwazve, anti-fog coating, uye laser scoring.
Ukobvu, mazinga ekudzivirira, uye kurapwa kwepamusoro zvinogona kugadziriswa zvichienderana nezvinodiwa pakurongedza.

Mafirimu aya akachengeteka here pakudya uye anotevedzera mitemo?

Ehe, mafirimu emhando yepamusoro emhando yepamusoro akagadzirwa zvichienderana nezvinodiwa neFDA, EU, uye GB.
Akachengeteka kuti asanganiswe zvakananga nechikafu nezvinwiwa, kusanganisira maapplication akaomeswa nechando, mufiriji, uye anogona kudzoserwa.
Zvitupa zvekuongorora (COA), mishumo yekuongorora kutama, uye mapepa edata rezvinhu zvinogona kupihwa kana zvakumbirwa.

Ndezvipi ukobvu huripo pamafirimu ane mipendero yakareba?

Ukobvu hunowanzova pakati pema microns makumi mashanu kusvika ku180 microns zvichienderana nechimiro uye mashandisirwo.
Mafirimu evacuum pouch anowanzova 70–150 microns, nepo ma laminates ezvekudya zvekudya zvemazuva ano anogona kunge akatetepa (20–60 microns).
Zvivakwa zvakagadzirwa nemaoko zvinogona kugadzirwa zvichienderana nekunzwa kwechigadzirwa uye zvinodiwa pakubata michina.

Mafirimu ane mipendero yakakura anogona kushandiswazve here kana kuti anogona kuchengetedza nharaunda?

Mafirimu ekare ekudzivirira zvinhu zvakawanda anonetsa kuadzokorodza.
Zvisinei, mafirimu ekudzivirira zvinhu zvinogona kudzokorodzwa zvemono-material (semuenzaniso, all-PE kana all-PP) ari kuwanikwa zvakanyanya, zvichipa mhinduro dzekuchengetedza dzinogara kwenguva refu.
Vamwe vagadziri vanopawo mafirimu ekudzivirira zvinhu zvakagadzirwa nebio-based vachishandisa zvinhu zvinogadziriswa compost sePLA kana cellulose.
Zvakakosha kuenzanisa zvinodiwa pakushanda nezvinangwa zvekuchengetedza panguva yekusarudza firimu.
