Muaj ntau ntau hom kev ntim dej haus, feem ntau yog iav fwj, cov kaus poom hlau, thawv, PET fwj, thiab lwm yam. Raws li lub thawv rau ntau yam dej haus tshiab, nws qhov zoo thiab qhov tsis zoo yog qhov zoo ib yam. Cov kev ua tau zoo ntawm lub thawv muaj xws li: kev rov tsim dua tshiab, kev siv tau zoo ntawm qhov chaw, qhov hnyav, thiab lwm yam. Tsis tas li ntawd, lub thawv kuj muaj cov yam ntxwv, uas yog, cov txheej txheem txheej ntawm lub thawv Kev Tshawb Fawb tau ua kom yooj yim rau kev ua tiav ntau yam khoom thaiv xws li light-shielding thiab oxygen barrier zog.
1. Carton qauv uas ua tau raws li qhov yuav tsum tau ua
Ntxiv rau qhov pom tseeb, lub thawv tuaj yeem ua tiav nws cov kev xav tau los ntawm nws cov qauv thiab cov khoom sib xyaw ua ke. Raws li cov duab, cov neeg sawv cev cartons suav nrog lub ru tsev lub thawv qauv cartons, square cartons thiab cartons ntawm lwm cov qauv.
2. Regenerative
Raws li tus neeg sawv cev cartons, muaj cov thawv ntim mis nrog lub ru tsev lub thawv qauv thiab cov thawv dej qab zib. Cov duab los qhia siv rau cov ntim mis no yog tsim los ntawm extruding polyethylene rau pem hauv ntej thiab sab nraum qab ntawm daim duab los qhia siv extruder. Txij li daim ntawv thiab polyethylene yog ib qho yooj yim rau tev los yog sib cais hauv cov tshuaj alkaline, cov txheej txheem ntawm daim ntawv yog ib qho yooj yim kom ua tiav. Kev rov ua dua tshiab ntawm cov ntim mis nyuj tau pom. Ntxiv nrog rau cov ntsiab lus hais saum toj no uas ua rau cov ntaub ntawv yooj yim rau rov tsim dua tshiab, muaj lwm qhov laj thawj uas tsuas yog cov ntaub so ntswg tiag tiag siv los tsim cov duab los qhia rau cov thawv.
3. Ntau yam khoom thaiv
Oxygen, dej vapor thiab lub teeb yog qhov ua rau cov khoom tsis zoo ntawm lub pob. Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws, nws yog ib qho tsim nyog yuav tau ua kom cov khoom thaiv ntawm lub thawv ntawv, ib qho ntawm txoj kev yog ua kom nws nrog aluminium ntawv ci. Raws li txoj kev no, lub thawv tuaj yeem nruab nrog kev ua haujlwm ntawm kev thaiv cov pa oxygen, dej vapor thiab lub teeb. Siv aluminium foil composite carton, cov ntsiab lus tuaj yeem khaws cia rau lub sijhawm ntev.
4. Daim ntawv ntug tiv thaiv qauv
Siv txoj kev luam ntawv uas haum rau cov kev xav tau ntawm cov neeg siv khoom, kev luam ntawv yog ua rau saum npoo ntawm daim duab los qhia lub thawv ua los ntawm extrusion xovxwm lamination txheej txheem. Cov txheej txheem luam ntawv tseem ceeb suav nrog gravure printing thiab offset printing. Gravure printing yog siv rau cov khoom loj, thiab offset printing yog siv rau cov khoom me me. Txawm li cas los xij, qee zaum txoj kev luam ntawv raug xaiv raws li qhov xav tau ntawm tus tsim. Cov ntawv luam tawm yog molded rau hauv qhov xav tau unfolded zoo, thiab tom qab ntawd los ntawm cov khoom siv hluav taws xob sib khi, cov nplaim roj siv los yaj cov polyethylene ntawm cov npoo ntawm sab xub ntiag thiab sab nraub qaum ntawm cov duab los qhia, thiab cov npoo ntawm sab xub ntiag thiab sab nraub qaum. ntawm cardboard yog melted. Kaw ib leeg los ua ib lub thawv.
5. Kev tiv thaiv ib puag ncig
Txawm hais tias kev siv cov ntawv txhuas txhuas muab qhov ua tau rau lub sijhawm ntev ntawm cov thawv ntim dej, nws yuav ua rau nyuaj rau kev rov ua dua cov ntawv qub, thiab tseem tuaj yeem ua rau muaj xwm txheej uas cov ntawv txhuas txhuas puas tsuaj rau lub incinerator thaum lub thawv ntawv yog incinerated. Los ntawm kev siv cov ntaub ntawv thaiv uas hloov cov ntawv txhuas, tag nrho cov kev xav tau ntawm kev tiv thaiv ib puag ncig thiab kev cia ntev ntev tuaj yeem ua tiav. Cov khoom siv lwm yam thaiv xws li EVO (Ethylene Vinyl Acetate Copolymer) thiab silicon nqus txheej.
6. Kev thaiv
Vim tias cov kua txiv hmab txiv ntoo yog ib qho yooj yim kom poob nws cov saj tshwj xeeb, lub luag haujlwm tseem ceeb rau cov thawv ntawv yog tswj cov saj tshiab ntawm cov khoom. Kua kua txiv yuav nqus cov ntxhiab nyob ib ncig ntawm nws, ua rau nws saj hloov. Rau cov ntsiab lus zoo li no, lub thawv yuav tsum muaj kev ua haujlwm ntawm kev thaiv cov ntxhiab tsw sab nraud. Yog tias cov khoom siv thaiv cov lus hais saum toj no tau siv, nws tuaj yeem ua tiav qhov thaiv sab nraud ntawm sab nraud.
