Aluminium ntawv ci yog cov khoom siv hlau nkaus xwb hauv cov khoom ntim. Nws muaj qhov zoo ntawm tsis muaj tshuaj lom, tsis muaj ntxhiab thiab muaj zog lub teeb-shielding zog. Thaum ua rau hauv blister ntim, nws tuaj yeem raug crushed nrog me ntsis siab, ua kom yooj yim rau cov neeg mob noj tshuaj thiab nqa tau yooj yim. Kev siv tshuaj kho mob aluminium ntawv nyiaj yog qhov dav thiab paub tab. Nws yog tsuas yog siv rau blister ntim ntawm cov tshuaj ntsiav tshuaj, ntsiav tshuaj, thiab lwm yam, nrog rau lub hnab ntim cov hmoov granules thiab kua. Cov txheej txheem yog tsim rau cov tshuaj aluminium foil bonded rau polyvinyl chloride (PVC), polyvinylidene chloride (PVDC) thiab lwm yam ntaub ntawv nyuaj, thiab siv rau ntim khoom siv tshuaj ( ntsiav tshuaj, tshuaj ntsiav, thiab lwm yam). Cov khoom siv kuaj pom muaj xws li cov khoom thaiv, pinhole degree, thaum tshav kub kub sealing lub zog ntawm cov nplaum txheej, tiv thaiv tshav kub thiab tawg lub zog ntawm txheej tiv thaiv, thiab lwm yam.
Aluminium ntawv ci muaj cov qauv siv lead ua zoo heev. Hauv kev xav, aluminium ntawv ci tuaj yeem thaiv txhua yam roj, dej vapor thiab lub teeb. Tab sis qhov tseeb, vim yog cov txheej txheem dov siv nyob rau hauv aluminium ntawv ci ntau lawm, qhov zoo ntawm cov roj dov, qhov xwm txheej ntawm cov yob yob nto, cov txheej txheem kev lag luam thiab cov chaw tsim khoom, ntau yam tsis xws luag yuav tshwm sim nyob rau hauv aluminium ntawv ci, tshwj xeeb tshaj yog nyias. aluminium ntawv ci. Pinholes yog ib qho tseem ceeb tshaj plaws. Qhov loj thiab tus naj npawb ntawm pinholes nyob rau hauv aluminium ntawv ci muaj kev txiav txim siab ntawm cov dej tsis kam, roj barrier thiab lub teeb-shielding zog ntawm aluminium ntawv ci thiab nws cov ntaub ntawv sib xyaw.
Tam sim no, nws tau dhau los ua ntau dua rau cov zaub mov noj qab haus huv thiab cov tshuaj ntsiav tshuaj thiab tshuaj ntsiav yuav tsum tau ntim rau hauv daim ntawv blister ntim. Aluminium-plastic blister ntim kuj tseem hu ua blister ntim, los yog PTP (Xovxwm los ntawm ntim) luv luv. Cov ntawv ci txhuas siv hauv cov ntim ntim ntim yog cov khoom siv sib khi nruj nreem kaw rau ntawm daim ntawv nyuaj ntawm cov tshuaj yas polyvinyl chloride (PVC), yog li nws tseem hu ua cov khoom siv lub hau. Yuav luag tag nrho cov khoom nyob rau hauv niaj hnub ntim uas yuav tsum tau opaque los yog high-barrier composite cov ntaub ntawv siv txhuas ntawv ci raws li lub barrier txheej. Qhov no yog vim tias cov ntawv txhuas txhuas muaj cov hlau siv lead ua muaj zog heev uas tuaj yeem thaiv txhua yam roj, yog li nws tau siv dav.
