Nkag mus rau lub xyoo pua 21st, qhov kev sib tw ntawm kev lag luam kev sib tw thiab cov khoom sib xws tau txhawb nqa txoj kev loj hlob sai ntawm cov khoom ntim. Xyoo 2002, qhov loj ntawm lub lag luam ntim thoob ntiaj teb tau tshaj US $ 500 billion. Txoj kev loj hlob ntawm aluminium foil ntim yog qhov tseem ceeb hauv kev sib txuas nrog kev txhim kho ntawm tag nrho cov kev lag luam.
Hauv kev ua lag luam hauv Suav teb, aluminium foil ntim tau tsim sai dua. Muaj ob lub laj thawj tseem ceeb: Ua ntej, kev txhim kho ntawm Tuam Tshoj txoj kev lag luam ntim khoom lag luam hloov pauv txawv txawv ntawm cov teb chaws tsim. Qhov kev faib ua feem ntawm cov ntim tau yooj yim rau cov khoom siv niaj hnub thiab khoom noj me me.
cov teb chaws tsim tau suav txog ntau dua 65%, thiab qee qhov tau tshaj 70%, thaum Tuam Tshoj suav txog li 15%, thiab qhov kev faib ua feem tau nce sai hauv ob xyoos dhau los; Thib ob, cov khoom siv hluav taws xob hauv tsev aluminium-yas composite thiab aluminium-paper composite technologies txuas ntxiv kom paub tab, thiab cov nqi tsim khoom raug txo.
Txhawb nqa qhov nrov thiab siv cov khoom siv aluminium-raws li cov khoom siv hauv Suav teb ntim khoom lag luam.
