Lifilimi tse kopantsoeng tsa High Barrier

Lifilimi tse kopantsoeng tsa High Barrier ke eng?

Lifilimi tse kopantsoeng tse nang le mekoallo e meholo ke lifilimi tse nang le mela e mengata tse etselitsoeng ho sireletsa dikahare tse pakiloeng ho tloha oksijeneng, mongobong, monkong, khanyeng le linthong tse ling tse kantle.
Lifilimi tsena hangata li kopanya thepa e kang PET, Nylon, EVOH, Aluminium foil, le PE/CPP ho fihlela ts'ebetso e ikhethang ea mekoallo.
Li sebelisoa haholo lijong, meriana le liphuthelong tsa indasteri tse hlokang nako e telele ea ho boloka le botšepehi ba sehlahisoa.

Ke thepa efe e atisang ho sebelisoa lifiliming tse nang le lithibelo tse phahameng?

Meaho e tloaelehileng ea thepa e kenyelletsa:
• PET/AL/PE (Filimi e kopantsoeng ea foil ea Aluminium)
• PET/NY/PE
• BOPP/EVOH/CPP
• Nylon/PE e nang le lera la mantlha la EVOH
• Filimi e kopantsoeng ea PET kapa BOPP e entsoeng ka tšepe.
Metsoako ena ea mekhahlelo e mengata e netefatsa ho hanyetsa oksijene le mongobo hantle ha e ntse e boloka ho tenyetseha le ho tiea.

Melemo ea bohlokoa ea ho sebelisa lifilimi tse kopantsoeng tse nang le lithibelo tse phahameng ke efe?

Lifilimi tse nang le lithibelo tse phahameng li fana ka melemo e latelang:
• Litšobotsi tse ikhethang tsa lithibelo tsa oksijene le mongobo
• Nako e telele ea ho boloka sehlahisoa le ho se be le botjha
• Monko o motle, tatso le tšireletso ea UV
• E loketse ho paka ka vacuum le ho paka sepakapaka se fetotsoeng (MAP)
• Libaka tse ka hatisoang bakeng sa ho ngola le ho ngola mabitso
• Matla a matla a mechini le ho hanyetsa ho phunyeha

Ke lits'ebetso life tse hlokang lifilimi tse nang le lithibelo tse phahameng?

Lifilimi tse kopantsoeng tse nang le mokoallo o moholo li sebelisoa haholo ho:
• Nama e pakiloeng ka vacuum, lisoseje le lijo tsa leoatleng
• Kofi, tee, le liphutheloana tsa lijo tse bobebe
• Meriana le lisebelisoa tsa bongaka
• Liphutheloana tsa chisi, lebese le phofo
• Lijo tsa liphoofolo tse ruuoang lapeng le limatlafatsi
• Lisebelisoa tsa elektroniki le tsa indasteri tse amohelang mongobo.

Lifilimi tse nang le lithibelo tse phahameng li bapisoa joang le lifilimi tse tloaelehileng?

Lifilimi tse tloaelehileng tse kopantsoeng li ka fana ka tšireletso ea motheo empa ha lia lokela lihlahisoa tse hlokang ho bolokoa nako e telele.
Lifilimi tse nang le lithibelo tse phahameng li kenyelletsa mekhahlelo e khethehileng joalo ka foil ea aluminium, EVOH, kapa PET e entsoeng ka tšepe ho fokotsa haholo sekhahla sa phetiso ea khase le mongobo (OTR le MVTR).
Li netefatsa tšireletso e betere ea sehlahisoa, haholo-holo maemong a thata a polokelo kapa a lipalangoang.

Na lifilimi tse nang le lithibelo tse phahameng li loketse ho paka ka vacuum le MAP?

E, lifilimi tse nang le mokoallo o moholo li atisa ho sebelisoa ka har'a mekotla ea vacuum le liphutheloana tse fetotsoeng tsa sepakapaka (MAP).
Ho kenella ha tsona ka tlase ho thusa ho tlosa oksijene le ho boloka naetrojene kapa CO₂, ho atolosa bocha le ho thibela kholo ea likokoana-hloko.
Li sebelisoa haholo ts'ebetsong ea nama, liphutheloaneng tsa chisi, le lits'ebetsong tsa lijo tse seng li loketse ho jeoa.

Na lifilimi tse nang le litšitiso tse phahameng li ka koaloa, tsa hatisoa, kapa tsa fetoloa hore li be tsa hau?

Ehlile. Lifilimi tsena li ka koaloa ka mocheso kapa ka serame, ho latela lera la ho koala (PE, CPP, EVA, jj.).
Li lumellana le gravure, flexo, le khatiso ea dijithale.
Likarolo tse ikhethileng li kenyelletsa li-notches tse tabohang habonolo, li-zipper tse ka koaloang hape, sekoahelo se thibelang moholi, le ho beha lintlha ka laser.
Botenya, maemo a thibelo, le kalafo ea bokaholimo kaofela li ka etsoa ho latela litlhoko tse itseng tsa ho paka.

Na lifilimi tsena li bolokehile lijong 'me li latela melaoana?

E, lifilimi tse kopantsoeng tse nang le lithibelo tse phahameng tsa boleng ba lijo li etsoa ho latela maemo a FDA, EU, le GB.
Li bolokehile bakeng sa ho kopana ka kotloloho le lijo le lino, ho kenyeletsoa le lits'ebetso tse hoamisitsoeng, tse sehatsetsing le tse ka khutlisoang.
Litifikeiti tsa tlhahlobo (COA), litlaleho tsa liteko tsa bofalli, le maqephe a data a thepa li ka fanoa ha ho kopuoa.

Ke botenya bofe bo fumanehang bakeng sa lifilimi tse nang le lithibelo tse phahameng?

Botenya hangata bo tloha ho di-micron tse 50 ho isa ho tse 180 ho latela sebopeho le ts'ebeliso.
Lifilimi tsa mokotla oa vacuum hangata ke di-micron tse 70-150, ha li-laminate tsa lijo tse bobebe li ka ba tšesaane (di-micron tse 20-60).
Meaho e ikhethileng e ka etsoa ho latela kutloisiso ea sehlahisoa le litlhoko tsa ts'ebetso ea mechini.

Na lifilimi tse nang le lithibelo tse phahameng li ka sebelisoa hape kapa li ka sireletsa tikoloho?

Lifilimi tsa setso tsa lithibelo tse nang le thepa e ngata li thata ho sebelisoa hape.
Leha ho le joalo, lifilimi tsa lithibelo tse ka sebelisoang hape tse nang le thepa e le 'ngoe (mohlala, all-PE kapa all-PP) li ntse li fumaneha ka bongata, li fana ka litharollo tsa ho paka tse tsitsitseng.
Bahlahisi ba bang ba boetse ba fana ka lifilimi tsa lithibelo tse thehiloeng linthong tsa tlhaho tse sebelisang thepa e ka manyolo joalo ka PLA kapa cellulose.
Ho bohlokoa ho bapisa litlhoko tsa ts'ebetso le lipheo tsa botsitso nakong ea khetho ea filimi.
