Lifilimi tse Kopanetsoeng tse Phahameng tsa Barrier

Lifilimi tsa High Barrier Composite ke life?

Lifilimi tse nang le litšitiso tse phahameng ke lifilimi tsa laminated tse ngata tse etselitsoeng ho sireletsa litaba tse pakiloeng ho tsoa ho oksijene, mongobo, monko, leseli le lintho tse ling tse kantle.
Hangata lifilimi tsena li kopanya lisebelisoa tse kang PET, Nylon, EVOH, Aluminium foil, le PE / CPP ho finyella ts'ebetso e tsotehang ea litšitiso.
Li sebelisoa haholo lijong, meriana le liphutheloana tsa indasteri tse hlokang nako e telele ea nako ea polokelo le botšepehi ba lihlahisoa.

Ke lisebelisoa life tse atisang ho sebelisoa lifiliming tse phahameng tsa lithibelo?

Mehaho ea lisebelisoa tse tloaelehileng li kenyelletsa:
• PET / AL / PE (Aluminium foil composite film)
• PET / NY / PE
• BOPP / EVOH / CPP
• Nylon / PE e nang le EVOH core layer
• Metallized PET kapa BOPP e entsoeng ka filimi
Metsoako ena e mengata e tiisang ho hanyetsa oksijene le mongobo ha e ntse e boloka ho feto-fetoha ha maemo le ho tiisa.

Melemo ea bohlokoa ea ho sebelisa lifilimi tse kopantsoeng tse phahameng ke life?

Lifilimi tse phahameng tse thibelang likokoana-hloko li fana ka melemo e latelang: • Mehato e
e thibelang oksijene le mongobo
Nako e atolositsoeng ea shelofo
•
ikhethang
ea sehlahisoa
le ho boloka bohloeki.

Ke likopo life tse hlokang lifilimi tse phahameng tsa lithibelo?

Lifilimi tse kopantsoeng ka mokhoa o phahameng oa lithibelo li sebelisoa haholo ho:
• Lijo tse pakiloeng ka vacuum, lisoseje le lijo tsa leoatleng
• Kofi, tee le lijo tse bobebe
• Meriana le lisebelisoa tsa bongaka
• Liphutheloana tsa chisi, lebese le phofshoana ea lijo
• Lijo tsa liphoofolo tse ruuoang lapeng le limatlafatsi
• Lisebelisoa tsa elektroniki le tsa indasteri tse thibelang mongobo.

Lifilimi tse phahameng tsa thibelo li bapisoa joang le lifilimi tse tloaelehileng?

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

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

Ee, lifilimi tse nang le litšitiso tse ngata li sebelisoa hangata ka har'a mekotla ea vacuum le liphutheloana tse fetotsoeng tsa moea (MAP).
Ho kenella ha bona ka tlase ho thusa ho tlosa oksijene le ho boloka naetrojene kapa CO₂, ho eketsa bocha le ho thibela kholo ea likokoana-hloko.
Li sebelisoa haholo ho lokisa nama, ho paka chisi, le likopong tsa lijo tse seng li loketse ho jeoa.

Na lifilimi tse thibelang litšitiso tse phahameng li ka koaloa, tsa hatisoa kapa tsa etsoa ka mokhoa o ikhethileng?

Ruri. Lifilimi tsena li ka koaheloa ka mocheso kapa ho bata, ho itšetlehile ka lera la ho tiisa (PE, CPP, EVA, joalo-joalo).
Li lumellana le khatiso ea gravure, flexo le digital.
Likarolo tseo u ka li khethang li kenyelletsa li-notch tse tabohang habonolo, lizipi tse ka lokisoang hape, tse thibelang moholi, le lintlha tsa laser.
Botenya, maemo a lithibelo, le kalafo ea bokaholimo kaofela li ka hlophisoa ho latela litlhoko tse ikhethileng tsa sephutheloana.

Na lifilimi tsee li bolokehile lijong ebile li latela melao?

Ee, lifilimi tse kopantseng litšitiso tse phahameng tsa lijo li etsoa ho latela litekanyetso tsa FDA, EU, le GB.
Li bolokehile bakeng sa ho kopana ka kotloloho le lijo le lino, ho kenyeletsoa lihatsetsi, sehatsetsing, le lits'ebetso tse ka khutlisetsoang.
Setifikeiti sa tlhahlobo (COA), litlaleho tsa liteko tsa ho falla, le maqephe a lintlha tsa thepa li ka fanoa ka kopo.

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

Botenya hangata bo tloha ho li-microns tse 50 ho isa ho tse 180 ho latela sebopeho le ts'ebeliso.
Lifilimi tsa 'vacuum pouch' hangata li na le li-microns tse 70-150, athe li-laminate tsa lijo tse bobebe li ka ba tšesaane (20-60 microns).
Mehaho e tloaelehileng e ka etsoa ho ipapisitsoe le kutlo ea sehlahisoa le litlhoko tsa ho sebetsana le mochini.

Na lifilimi tse nang le lithibelo tse phahameng li ka sebelisoa hape kapa li na le botsoalle?

Lifilimi tsa setso tse thibelang lintho tse ngata li thata ho li sebelisa hape.
Leha ho le joalo, lifilimi tsa 'mono-material recyclable' (mohlala, all-PE kapa all-PP) li ntse li eketseha, li fana ka litharollo tse tšoarellang tsa ho paka.
Baetsi ba bang ba boetse ba fana ka lifilimi tse thibelang likokoana-hloko tse sebelisang lisebelisoa tse nang le manyolo a kang PLA kapa selulose.
Ho bohlokoa ho bapisa litlhoko tsa ts'ebetso le lipakane tsa ts'ebetso nakong ea khetho ea lifilimi.
