Tom qab ze li ib puas xyoo ntawm txoj kev loj hlob, aluminium ntawv ci tau dhau los ua cov khoom ntim loj. Nws txoj kev loj hlob ntawm kev lag luam yog paub tab nyob rau hauv cov teb chaws Europe thiab Amelikas, tab sis nyob rau hauv Suav lag luam, aluminium foil ntim tseem muaj kev cia siab dav. Cov hauv qab no yog kev tsom xam ntawm cov lag luam tseem ceeb rau aluminium ntawv ci hauv cov ntim khoom yooj yim.
Hauv xyoo 2002, tus nqi tsim tawm ntawm kev lag luam ntim tshuaj thoob ntiaj teb yog ze li ntawm US $ 11 nphom, nrog qhov kev loj hlob nruab nrab ntawm 4%. Tus nqi tsim tawm ntawm Tuam Tshoj cov tshuaj ntim khoom lag luam yog kwv yees li US $ 1.8 billion, nrog qhov nruab nrab txhua xyoo kev loj hlob ntawm ntau dua 10%. Aluminium foil feem ntau yog siv rau kev ntim tshuaj blister hauv kev ntim tshuaj.
Blister ntim yog tsim los ntawm polyvinyl chloride nplooj (PVC) thiab 0.02mm tuab aluminium ntawv ci. Blister ntim tau dhau los ua txoj kev ntim khoom tseem ceeb tshaj plaws rau Western tshuaj ntsiav tshuaj thiab tshuaj ntsiav. Lub ntim ntawm cov tshuaj suav tshuaj suav tshuaj, hmoov, tshuaj ntsiav, thiab tshuaj hauv kuv lub teb chaws yog maj mam hloov los ntawm cov hnab ntawv, hnab yas yooj yim, thiab cov iav fwj mus rau cov ntim ntim yas yas. Blister ntim muaj qhov zoo ntawm kev ua kom tsis muaj dej noo, yooj yim nqa, nyab xeeb thiab huv. Nrog rau txoj kev loj hlob ntawm cov tshuaj tiv thaiv-tso technology, kev ua lag luam yuav ua kom dav. Tam sim no, qhov kev thov txhua xyoo rau cov ntawv txhuas txhuas hauv cov thawv ntim khoom yog ntau dua 7,000 tons, thiab nws xav tias yuav tshaj 10,{8}} tons hauv xyoo 2005.
