Muaj ntau ntau hom PP zaj duab xis haum rau cov ntawv khob ntim tshuab, uas nws cov yam ntxwv zoo sib xws nrog cov khoom ntim ntawm cov ntawv khob:
1.Biaxially oriented polypropylene zaj duab xis
Nta
High transparency thiab glossiness: Tom qab biaxial stretching, molecular strands ntawm BOPP zaj duab xis yog teem nyob rau hauv orientation thiab nto yog du thiab txawm. Cov nyhuv luam ntawv yog vivid, tuaj yeem pom meej lub logo lossis qauv ntawm lub khob ntawv.
Cov khoom thaiv zoo heev: kev thaiv cov dej vapor, oxygen thiab lwm yam gases zoo dua li cov yeeb yaj kiab polypropylene zoo tib yam, tuaj yeem txuas lub neej txee ntawm daim ntawv khob (xws li mis nyuj tshuaj yej, kua txiv hmab txiv ntoo, thiab lwm yam).
Thaum tshav kub kub tsis kam: 164-170℃melting point, tuaj yeem tiv taus qhov kub thiab txias los yog lub sij hawm luv luv microwave cua sov, haum rau cov ntim dej kub.
Lub zog txhua yam: Lub zog tensile thiab kev cuam tshuam tsis zoo tuaj yeem txhim kho, txo qhov kev pheej hmoo ntawm deformation lossis kev puas tsuaj ntawm cov khob ntawv thaum thauj.
Daim ntawv thov scenarios
High- khob khob dej haus, xws li kas fes thiab tshuaj yej, yuav tsum muaj cov xwm txheej uas qhia txog lub hom phiaj pom thiab xav tau lub neej txee.
Qhwv rau hauv daim ntawv khob uas yuav tsum tau ntim cov kub los yog microwave cua sov (xws li npaj tau-- noj kua zaub thiab porridge).
2.Unstretched polypropylene zaj duab xis (CPP)
Nta
Kev ua haujlwm zoo thermal sealing: CPP zaj duab xis yog npaj los ntawm txoj kev casting nrog du nto thiab dav thermal sealing kub ntau yam (feem ntau yog 120-140 degree). Tight rau ntawm ntug ntawm daim ntawv khob, muaj zog sealing kev ua tau zoo.
Zoo elasticity: Piv rau BOPP, CPP zaj duab xis yog softer, haum rau sealing tsis xwm yeem zoo li lub khob khob (xws li conical thiab arc -zoo li tus khob lub qhov ncauj) thiab tsis yooj yim rau wrinkle los yog plam sealing.
4. Tus nqi qis: cov txheej txheem tsim khoom yooj yim, kev siv cov khoom siv raw, tus nqi qis dua BOPP, haum rau loj - nplai ntau lawm.
Daim ntawv thov scenarios
Tsawg- tus nqi sib khi yog yuav tsum tau rau cov dej haus txias haus cov khob ntawv (xws li cov dej haus carbonated thiab kas fes iced), tab sis cov khoom thaiv tsis tas yuav tsum muaj.
Cov khob ntawv pov tseg, hais txog kev sib khi ceev ceev thiab kev lag luam.
3. Co-extruded polypropylene zaj duab xis
Nta
Multi- txheej txheej: siv co-extrusion technology, PP txheej (xws li txheej txheej thaiv, txheej txheej thaum tshav kub kub sealing) nrog cov haujlwm sib txawv tuaj yeem ua ke kom tau raws li qhov yuav tsum tau muaj kev thaiv siab, siab zog thiab cua sov yooj yim- sealing.
Customized kev ua tau zoo: Piv txwv li, txheej txheej siv BOPP los muab cov ntawv luam tawm thiab cov khoom thaiv, cov txheej sab hauv siv CPP lossis PP cov ntaub ntawv tshwj xeeb los txhim kho cov cua sov sealability, thiab cov txheej nruab nrab ntxiv cov khoom thaiv (xws li EVOH) los txhim kho cov pa thiab cov tshuaj tsw qab.
Daim ntawv thov scenarios
Ntev -txheej- lub khob haus dej lub neej (xws li mis nyuj, kua txiv hmab txiv ntoo, thiab lwm yam) yuav tsum tau ua kom tau raws li qhov xav tau ntawm cov dej noo, antioxidant thiab yooj yim rau seal.
High -khoom plig ntawv khob yog qhov zoo tagnrho rau cov xwm txheej uas cov ntim xav tau ob qho tib si hauv qhov tsos thiab ua haujlwm.
4. Aluminium lossis metallized PP zaj duab xis
Nta
High barrier khoom: los ntawm lub tshuab nqus tsev aluminium plating txheej txheem nyob rau saum npoo ntawm polypropylene zaj duab xis tso ib txheej ntawm txhuas zaj duab xis, tuaj yeem txhim kho qhov tsis kam rau oxygen thiab dej vapor ob peb zaug, mus txog qib ntawm aluminium ntawv ci.
Hlau luster: zoo ib yam li tab sis softer tshaj ntawv ci, haum rau cov ntawv khob ntim uas yuav tsum tau siab - kawg visuals.
Thaum tshav kub kub-resistant: Thaum tshav kub kub sealing yuav ua tau nyob rau hauv daim ntawv khob los ntawm kev siv lub tshav kub resistant seals xws li PE los yog tshwj xeeb PP.
Daim ntawv thov scenarios
High-cov dej haus kawg lossis cov khob ntawv zaub mov (xws li cov kua txiv hmab txiv ntoo thiab cov khoom noj qab haus huv) uas yuav tsum tau khaws cia ntev thiab tseem ceeb rau qib ntim.
Lub khob ntim ntawv yuav tsum tau muab cia kom deb ntawm lub teeb (xws li qee lub zog haus).
5. Xaiv cov lus pom zoo
Rau cov dej txias tsis tu ncua haus cov khob ntawv: CPP zaj duab xis yog nyiam vim ob qho tib si tus nqi thiab kev sib khi ua kom sov.
Rau cov dej kub los yog cov khob ntawv uas yuav tsum tau siv cua sov microwave: Xaiv BOPP zaj duab xis los xyuas kom meej cov cua sov thiab cov neeg kho tshuab lub zog.
Ntev thav duab los yog qib siab khob ntawv: ua los ntawm co-extruded PP zaj duab xis los yog aluminium coated polypropylene zaj duab xis, ntsuas qhov teeb meem, qhov tsos thiab tus nqi.
Cov kev cai tshwj xeeb: kev hloov kho polypropylene zaj duab xis (xws li halo- kho BOPP) tuaj yeem siv yog tias yuav tsum muaj kev tiv thaiv antistatic lossis UV tiv thaiv.
Kev tiv thaiv
Thermal sealing parameter adjustment: Lub tshav kub sealing kub thiab siab ntawm cov polypropylene films sib txawv yuav tsum tau optimized raws li cov khoom siv (xws li tsis siv neeg khob sealing tshuab, semi- tsis siv neeg khob sealing tshuab) kom tsis txhob xoob sealing los yog zaj duab xis deformation.
Printing compatibility: BOPP cov yeeb yaj kiab cov yeeb yaj kiab luam tawm zoo tshaj yog tias koj xav tau luam tawm cov qauv ntawm lawv, thaum CPP cov yeeb yaj kiab yuav tsum tau kho ua ntej (xws li kev kho mob corona) txhawm rau txhim kho cov xim adhesion.
