Cov yam ntxwv thiab kev ua haujlwm ntawm lub siab barrier aluminium ntawv ci

1. High barrier aluminium foil yog mos thiab tsis yooj yim rau tawg
High barrier aluminium foil yuav tsum tsis txhob tawg yooj yim thaum folded thiab yuav tsum muaj kev ua haujlwm zoo. Cov ntawv txhuas yuav tsum tau khaws cia rau hauv lub xeev qhuav, thiab lub sijhawm cia yuav tsum tsis txhob ntev dhau. Nws yuav tsum tau siv sai li sai tau los tiv thaiv nws los ntawm absorbing noo noo thiab oxidation.
High barrier aluminium foil yog hlau. Cov hnab ntim khoom noj siv cov ntawv txhuas mos nrog lub thickness ntawm 9 μm (tseem 7 μm). Nws muaj cov dej noo zoo heev, roj barrier thiab lub teeb barrier zog. Muab tsis muaj kev puas tsuaj thiab pinholes, nws yog kiag li impermeable rau ya raws, huab cua thiab lub teeb thiab tsis tshua muaj kub thiab roj resistant. Yog li ntawd, lub hnab ntim khoom sib xyaw uas muaj cov ntawv txhuas muaj lub luag haujlwm ntawm kev ua tiav sealing, siab aroma preservation, siab roj kuj thiab kub tsis kam.
2. Tus naj npawb ntawm pinholes nyob rau hauv siab barrier aluminium ntawv yuav tsum tsawg
Nws yuav tsum yog cov khoom thaiv zoo, tab sis yog tias muaj cov pinholes, nws txoj kev ua haujlwm tsis zoo yuav raug txo kom tsawg, roj thiab lub teeb yuav nkag mus ncaj qha, thiab nws cov ntsiab lus tseem yuav hloov sai sai. Feem ntau, qhov tuab ntawm cov ntawv ci, qhov qis ntawm cov pinholes. Piv txwv li, lub thickness ntawm 7μm txhuas ntawv yuav tsum tsawg tshaj li 200 qhov ib square meter: rau 9μm txhuas ntawv ci, tus pinholes yuav tsum tsawg tshaj li 100 qhov/square meter. Txawm hais tias cov ntawv txhuas tuab npaum li cas, txoj kab uas hla ntawm lub pinhole yuav tsum tsis txhob loj dua 20μm.
3. Qhov kev huv huv ntawm cov ntaub thaiv npog aluminium ntawv yuav tsum siab
Tsis muaj roj thiab hmoov av ntawm qhov chaw, thiab qhov nro ntawm qhov chaw yuav tsum siab, uas yuav tsum siab tshaj 72mN / m. Ib txoj hauv kev yooj yim los ua qhov no yog xyuas cov dej distilled, uas yuav tsum tau ntub tag nrho ntawm cov ntawv ci txhuas. Yog hais tias cov roj nyob rau saum npoo ntawm cov ntawv ci txhuas yog qhov hnyav, nws yuav cuam tshuam rau cov xim sib xyaw kom nrawm ntawm cov ntawv ci txhuas thiab lwm yam ntaub ntawv, tshwj xeeb tshaj yog tom qab lub hnab ua noj kub kub, delamination yuav tshwm sim.
