Vim tias txhuas yog ib qho yooj yim rau yob thiab xuas nrig ntaus tawm, nws tuaj yeem ua rau hauv cov thawv ntawm ntau cov duab. Nws yog dav siv nyob rau hauv txhuas raj, aluminium-yas blister ntim, thiab ob chav aluminium ntawv ci ntim. Nws yog cov khoom siv dav siv tshaj plaws. Aluminium ntawv ci tuaj yeem ua rau hauv ntim ntawm ntau yam duab vim nws yooj yim dov thiab xuas nrig ntaus cov yam ntxwv, thiab yog dav siv nyob rau hauv txhuas raj, aluminium-yas hlwv ntim, ob chav aluminium ntawv ci ntim thiab lwm yam teb. Raws li cov khoom siv, aluminium ntawv ci muaj ntau yam kev siv hauv kev ntim khoom.
Aluminium ntawv ci muaj cov khoom zoo noo noo-pov thawj thiab tiv thaiv oxidation, uas tuaj yeem tiv thaiv cov khoom ntim tau zoo, ua kom ntev lawv lub txee lub neej thiab tswj lawv cov tshiab. Tsis tas li ntawd, aluminium ntawv ci kuj muaj cov khoom luam ntawv zoo heev, thiab ntau yam qauv zoo nkauj thiab cov ntawv tuaj yeem luam tawm ntawm nws qhov chaw kom tau raws li qhov xav tau ntawm kev ntim khoom.
Daim ntawv thov technologies xws li txhuas raj, txhuas-yas blister ntim thiab ob chav aluminium foil ntim kuj muaj lawv tus kheej yam ntxwv thiab zoo. Piv txwv li, txhuas raj tuaj yeem muab kev ua haujlwm zoo dua thiab kev sib khi, thiab tsim nyog rau qee lub sijhawm ntim khoom uas yuav tsum tau tiv taus siab dua; aluminium-yas hlwv ntim ntim muaj kev tiv thaiv zoo dua thiab zoo nkauj, thiab haum rau qee qhov ntim uas yuav tsum tau muab tso tawm. Muab ob npaug rau aluminium foil ntim tuaj yeem muab cov ntaub ntawv pov thawj zoo dua noo noo, oxygen-pov thawj thiab txuag hluav taws xob, thiab tsim nyog rau qee yam khoom uas yuav tsum tau khaws cia thiab thauj mus ntev.
