Aluminium ntawv ci yog dav siv los kaw cov thawv yogurt (xws li khob yas) thiab vim yog acidic xwm ntawm yogurt thiab qhov yuav tsum tau ntawm tshav kub sealing, aluminium ntawv ci feem ntau coated nrog ib txheej ntawm yas. Yog tias siv lub khob yas preformed, aluminium ntawv ci hau feem ntau yog precut thiab nyob ib ncig ntawm 2500-3000 lub hau tau ntim rau hauv cov ntawv xov xwm tshwj xeeb kom txo qis kev puas tsuaj. Txoj kab uas hla ntawm cov hau no yog<100 mm, and they usually have a pull-tab for easy opening.
Qhov ntsuas ntawm cov ntawv ci yog nyob ib ncig ntawm 40 μm, thiab txhua lub hau yog nquag embossed. Cov qauv embossing tuaj yeem sib txawv raws li cov neeg siv khoom xav tau thiab qhov kev xav tau tuaj yeem ncav cuag 100 μm hauv qhov tob. Lub embossing yog qhov tseem ceeb los pab txhawb nqa yooj yim ntawm ib lub hau los ntawm cov ntawv xov xwm sib dhos ua ntej muab tso rau hauv lub khob ntim thiab kub sealing.
