Lifilimi tse Chesang le tse Batang tse Kopantsoeng ke Eng?

Lifilimi tse kopantsoeng tse chesang le tse batang ke lifilimi tsa polasetiki tse nang le mekhahlelo e mengata tse etselitsoeng ho sebetsa tlas'a lits'ebetso tsa ho kopanya mocheso le khatello ea tikoloho.
Hangata li entsoe ka thepa e kang PET, BOPP, PE, CPP, kapa Nylon e kopantsoeng hammoho ho sebelisoa likhomaretsi kapa co-extrusion.
Lifilimi tsena li sebelisoa haholo ho paketeng, khatisong, lamination le lits'ebetsong tsa ho kenya mocheso ka lebaka la ho tenyetseha ha tsona mochesong le botšepehing ba sebopeho.

Phapang e ka sehloohong pakeng tsa lifilimi tse chesang tse kopantsoeng le lifilimi tse batang tse kopantsoeng ke efe?

Lifilimi tse kopanyang tse chesang li hloka mocheso le khatello bakeng sa ho kopanya—tse sebelisoang hangata ho lamination ea mocheso kapa lits'ebetsong tsa ho tiisa mocheso.
Ka lehlakoreng le leng, lifilimi tse kopanyang tse batang li ka sebelisoa ho sebelisoa likhomaretsi tse utloang khatello ntle le mocheso, e leng se etsang hore li lokele ho lamination e batang kapa lits'ebetso tsa mocheso o tlase.
Lifilimi tse ling tse kopanyang li entsoe ho tšehetsa ho kopanya ho chesang le ho batang, li fana ka mekhoa e mengata ea ts'ebeliso.

Ke thepa efe e sebelisoang hangata lifiliming tse chesang le tse batang tse kopantsoeng?

Meaho e tloaelehileng ea thepa e kenyelletsa:
• PET/PE
• BOPP/CPP
• Nylon/PE
• BOPP/PE e nang le likhomaretsi tse thehiloeng ho EVA kapa tse qhibilihang.
Metswako ena e fana ka thepa e lakatsehang joalo ka tšireletso ea lithibelo, ho hanyetsa mocheso, ponaletso le ho tiea.

Litšebeliso tse tloaelehileng tsa lifilimi tse kopaneng tse chesang le tse batang ke life?

Lifilimi tse kopantsoeng li sebelisoa liindastering tse fapaneng, ho kenyeletsoa:
• Sephutheloana sa lijo se tenyetsehang (mekotla ea lijo tse bobebe, lijo tse hatselitsoeng, mekotla ea lebese)
• Ho betla pampiri ka mocheso, likarete, kapa sephutheloana se tenyetsehang
• Ho tiisa mekotla ea meriana le ea bongaka
• Ho kenya mocheso kapa ho phuthela ka tšireletso
• Li-label, thepa ea papatso, le mecha ea khatiso e nang le laminated
Ho ikamahanya ha tsona le mocheso ho etsa hore li be ntle bakeng sa lits'ebetso tse iketsang kapa tsa letsoho.

Na lifilimi tsena tse kopantsoeng li loketse ho paka lijo?

E, lifilimi tse ngata tse kopaneng tse chesang le tse batang li hlahisoa ka li-resin le likhomaretsi tse sireletsehileng lijong.
Li fihlela melao ea FDA, EU, le GB ea ho kopana le lijo 'me li fana ka litšobotsi tse ntle tsa thibelo mongobong, oksijene le monko.
Li sebelisoa hangata ka har'a mekotla ea vacuum, mekotlaneng ea retort le liphuthelong tsa lijo tse bobebe.

Melemo ea ho sebelisa lifilimi tse kopantsoeng tse chesang le tse batang ke efe?

• Matla a phahameng a mechini le ho hanyetsa ho phunya
• Ho printa ho babatsehang le boreledi ba bokaholimo
• Ho tlamahana ho matla le pampiri, boto, kapa lifilimi tse ling
• Ho hanyetsa oli, mafura le lik'hemik'hale
• Ho lumellana le lits'ebetso tsa ho koala mocheso le tsa ho thiba serame
• Tshebetso ea thibelo e ka fetoloang ka ho sebelisa tšepe kapa ho koahela lera

Ke botenya bofe bo fumanehang bakeng sa lifilimi tse kopaneng tse chesang le tse batang?

Botenya bo fapana ho latela sebopeho le ts'ebeliso ea filimi, hangata bo tloha ho li-micron tse 20 ho isa ho li-micron tse 150.
Lifilimi tse tšesaane (mohlala, li-micron tse 25-40) li sebelisoa bakeng sa ho lamination kapa likarolo tse ka hare, ha lifilimi tse teteaneng (tse fetang li-micron tse 80) li fana ka matla a betere le ho koala bakeng sa sephutheloana sa kantle.
Lifilimi tse nang le mekhahlelo e mengata li ka kopanya litekanyo tse fapaneng bakeng sa ntlafatso ea ts'ebetso.

Na lifilimi tsena li ka hatisoa kapa tsa etsoa ka tšepe?

E, boholo ba lifilimi tse kopantsoeng li ka hatisoa ka mekhoa ea gravure, flexographic, kapa dijithale.
Mefuta e entsoeng ka tšepe (joalo ka PET kapa BOPP e entsoeng ka tšepe) e fana ka thepa e ntlafalitsoeng ea thibelo le litlamorao tsa pono bakeng sa liphutheloana tsa boleng bo holimo.
Kalafo ea Corona kapa ea lik'hemik'hale e netefatsa ho khomarela enke e matla le ho hlahisa 'mala o khanyang.

Na lifilimi tse kopantsoeng tse chesang le tse batang li ka sebelisoa hape?

Ho itshetlehile ka sebopeho sa thepa.
Dibopeho tsa thepa e le nngwe tse kang di-laminate tsa PE/PE kapa PP/PP di ka sebediswa hape.
Difilimi tse kopaneng tsa thepa e ngata (mohlala, PET/PE kapa BOPP/Nylon) di thata ho di sebedisa hape empa di ka etswa hore di be mosa tikolohong haholoanyane ka ho sebedisa dikhomaretsi tse se nang solvent kapa dikarolo tse bolang.
Bahlahisi ba ntse ba fana ka difilimi tse kopaneng tse ka sebediswang hape kapa tse nang le thepa e le nngwe bakeng sa ditharollo tse tsitsitseng tsa ho paka.

Keletso ea hore na nako ea ho boloka lintho e tla ba efe le hore na li tla bolokoa nako e kae ke efe?

Tlas'a maemo a loketseng a polokelo—a pholileng, a omileng, le a hole le letsatsi le tobileng—lifilimi tse kopantsoeng hangata li na le nako ea ho boloka ea likhoeli tse 12 ho isa ho tse 18.
Ho khothalletsoa ho boloka tikolohong e laoloang ke mocheso (15–25°C) ho thibela ho kobeha, tahlehelo ea ho khomarela, kapa ho senyeha ha khatiso.
