Aluminium ntawv nyiaj (los yog txhuas ntawv nyiaj nyob rau hauv North America; nquag hu ua tin foil) yog txhuas npaj nyob rau hauv tawv nqaij hlau nplooj nrog ib tug tuab npaum li cas tsawg tshaj li xoom.2 hli (7.9 mils);thinner gauges mus rau 6 micrometers (0.24 mils) kuj tau siv ib txwm.Hauv Teb Chaws Asmeskas, foils feem ntau ntsuas hauv txhiab ntawm ib nti lossis mils.Cov ntawv ci hauv tsev feem ntau yog xoom.016 hli (0.63 mils) tuab, thiab lub luag haujlwm hnyav hauv tsev ntawv ci feem ntau yog xoom.024 hli (zero.94 mils).Cov ntawv ci yog pliable, thiab tej zaum yuav yooj yim khoov los yog qhwv ib ncig ntawm cov khoom.Cov ntawv nyias nyias nyias nyias nyias thiab qee zaus laminated nrog lwm cov ntaub ntawv uas suav nrog cov yas lossis ntawv ua rau lawv muaj zog thiab muaj txiaj ntsig ntxiv.
Aluminium foil supplanted tin foil nyob rau hauv nruab nrab xyoo pua nees nkaum.Hauv tebchaws United Kingdom thiab United States nws yog mais feem ntau hu ua "tin foil", ib yam li cov kaus poom hlau tsis tu ncua tseem hu ua "tin poom").Metallised films yog ib zaug nyob rau hauv ib lub sij hawm flawed rau txhuas ntawv ci, tab sis muaj tseeb polymer films npog nrog ib tug tawv nqaij txheej ntawm txhuas.Nyob rau hauv teb chaws Australia, aluminium foil yog feem ntau hu ua alfoil.
Ntawv nyiaj crafted los ntawm ib daim tawv nqaij tawv ntawm tin ua lag luam muaj ua ntej tshaj nws cov txhuas counterpart.Tin foil tau tshaj tawm kev lag luam los ntawm lub sijhawm dhau 19th mus rau thaum ntxov xyoo pua 20th.Lo lus "tin foil" muaj sia nyob hauv lus Askiv raws li lub sijhawm rau cov ntawv txhuas tsis ntev los no.Tin foil yog me ntsis malleable dua li txhuas ntawv ci thiab nyiam muab cov tin saj me me rau cov zaub mov qhwv hauv nws.Tin foil tau hloov los ntawm txhuas thiab lwm yam ntaub ntawv rau qhwv cov zaub mov.
Txoj hauv kev tsis nres casting yog qhov tsis txaus ntseeg ntau lub zog hauv qhov tob thiab tau los ua cov txheej txheem nyiam.Rau cov thicknesses hauv qab xoom.0.5 hli (1 mil), cov khaubncaws sab nraud povtseg feem ntau muab tso ua ke rau qhov kawg hla thiab tom qab ntawd sib cais uas tsim cov ntawv ci nrog ib sab ci iab thiab ib sab matte.Cov yam hauv kev sib cuag nrog txhua qhov sib txawv yog matte thiab sab nraum zoov qhov kawg ua kom muaj zog;qhov no yog ua tiav los txo tearing, boom manufacturing quotes, tswj thickness, thiab tau hla qhov xav tau rau ib tug me me txoj kab uas hla curler.

Aluminium ntawv ci muaj qhov ci ntsa iab thiab ib sab matte.Lub ci ntsa iab facet yog tsim thaum lub txhuas yog dov rau lub sij hawm ntawm qhov kawg hla.Nws yog ib qho nyuaj rau tsim rollers nrog qhov qhib thawj-tus nqi txaus los tiv nrog cov ntawv ci ntsuas, yog li ntawd, rau qhov kawg dhau, cov nplooj ntawv yog dov nyob rau lub sijhawm zoo tib yam, ob npaug ntawm cov thickness ntawm qhov ntsuas ntawm kev nkag mus rau cov menyuam.Thaum cov nplooj ntawv sib cais tom qab, hauv pem teb sab hauv yog npub, thiab tawm ntawm qhov rooj hauv pem teb yog ci.Qhov sib txawv hauv qhov kawg no tau ua rau muaj kev xav tias kev nyiam ib sab muaj qhov cuam tshuam thaum ua noj.Txawm hais tias muaj coob tus pom zoo nrog (tsis ncaj ncees lawm) tias cov tsev tshwj xeeb khaws cia cov cua sov tawm thaum qhwv nrog lub vibrant tiav kev sib tham nrog tawm, thiab khaws cia sov so nrog cov ci ntsa iab ua tiav nrog rau sab hauv, qhov sib txawv tiag tiag yog qhov tsis pom zoo yam tsis muaj kev ntsuas.Ua kom pom tseeb txo qis txhua qhov nqus thiab emission ntawm hluav taws xob.Cov ntawv ci kuj tseem muaj cov txheej uas tsis yog lo rau ntawm ib sab uas yooj yim tshaj plaws.Lub reflectivity ntawm ci ntsa iab aluminium ntawv ci yog 88% thaum npub embossed ntawv ci yog npaj 80%.
