Dab tsi yog thawj cov ntawv thov ntawm kev lag luam aluminium ntawv ci hauv cov khoom noj ntim khoom noj?
Industrial txhuas ntawv ci yog dav siv rau kev hloov cov khoom lwj uas muaj cov khoom noj qab zib, nqaij, thiab npaj-noj mov vim lawv cov teeb meem zoo heev. Lawv pab raws li sab hauv cov ntaub pua chaw rau cov khoom ntim ntim, muab cov pa (oxygen (<0.5 cm³/m²/day) and moisture barrier (<0.1 g/m²/day) protection. Common applications include aseptic liquid cartons, retort pouches for sterilized foods, and twist wraps for chocolates. The rolls can be customized in widths from 200mm to 1600mm to fit different packaging machines. Recent innovations include pre-printed foil rolls for direct branding on packaged foods.
Ua li cas cov khoom noj-qib Aluminium Ntawv ci txawv ntawm cov qauv muaj ntawv ci?
Cov Khoom Noj Khoom Noj Yuav Tsum Ua Raws Cai FDA \/ EC1935 Cov Qauv Hais Txog Cov Hlau Mival Mightration (txhuas<0.01mg/kg). It undergoes additional annealing processes to achieve higher purity (99.7%+ aluminum) and smoother surfaces (Ra <0.5μm). Special lubricants are used during rolling that are NSF-certified as food-safe. Unlike standard foil, food-grade versions often feature anti-corrosion treatments using food-compatible passivation agents. The material requires certification for direct food contact applications including high-temperature uses like ovenable trays.
Dab tsi tuab ntau yog muaj rau cov khoom noj ntim ntawv kub?
Cov qauv tuab ntawm ultra-nyias 6μm ntawv ci rau chocolate wraps rau hnyav-zog 50μm ntawv rau cov thawv rigid. Siv lub tshuab ntim khoom siv tau yooj yim tshaj plaws {4}} μm Thicker 30-50 μm rolls yog siv rau cov tais tais ua ntej thiab cov hau ntim khoom noj. Txhua lub thickness yog precision-tswj (± 3% kam rau) los ntawm laser gauging tshuab thaum lub sijhawm tsim khoom. Qhov kev xaiv yog nyob ntawm cov khoom lag luam uas yuav tsum tau, muaj zog siv, thiab tus nqi txiav txim siab ib qho xwm txheej.
Dab tsi kho cov kev kho mob txhim kho cov zaub mov ntim cov khoom noj?
Cov kev kho mob ib txwm muaj xws li corona paug ({{0}}} dynes \/ cms} dynes \/ cms} dynes \/ cmination rau lamination. Qee cov ntawv ci tau txais Silicone Txheej (0. {{{2} g \/ m²) rau cov ntawv thov yooj yim. Antimicrobial Txheej txheej muaj cov nyiaj ions yog tawm rau cov khoom noj khoom noj tshiab. Ua ntej-lacquered ntawv ci nrog cov txheej txheej kub-featerable (pp-based) piv txwv cov dej ntws. Rau cov ntawv thov luam tawm, Primer txheej txheej kom ntseeg tau rau hauv cov kua nplaum thaum tswj hwm FDA ua raws li. Cov kev kho no yuav tsum tiv thaiv kom tsis muaj menyuam yaus ua kom zoo li 121 degree \/ 15min retort tej yam kev mob.
Yuav ua li cas ua aluminium ntawv ci pab txhawb kom cov zaub mov muaj khoom ntim khoom?
Txawm hais tias lub zog-intensive los tsim, ntawv ci kua Ultra-nyias gauges (qis rau 6μm) txo cov kev siv ib pob. Nws cov teeb meem zoo heev nthuav tawm cov zaub mov txee lub neej los ntawm 3-5 x, txo cov khib nyiab pov tseg. Niaj hnub nimno ub ntws tau tuaj yeem muab rov qab cov ntawv ci los ntawm kev sib xyaw ntim los ntawm pyrolysis sib cais. Qee cov tuam ntxhab tam sim no muab cov ntawv ci nrog 30% rov ua cov ntsiab lus tsis muaj kev cuam tshuam teeb meem. Kev siv lub zog nkaus rau cov ntawv ci feem ntau muaj cov ntawv qhia me me dua cov khoom siv pov tseg thaum xaiv cov zaub mov pov tseg. Mono-cov qauv qauv sib txuas cov ntawv nyiaj nrog cov polymers rov siv dua tshiab yog hauv qab kev loj hlob.
