Aluminium foil (kana aruminiyamu foil kuNorth America; kazhinji zvisina kurongwa inonzi tin foil) ndeye aruminiyamu yakagadzirwa neganda resimbi mashizha ane ukobvu zvisingasviki zero.2 mm (7.9 mils);mageji matete anodzika kusvika matanhatu micrometres (0.24 mils) zvakare anowanzo shandiswa.MuUS, mapepa anowanzo kuyerwa muzviuru zve inch kana mils.Foil yemumba yakajairika inowanzonzi zero.016 mm (0.63 mils) gobvu, uye rinorema rebasa remumba foil rinowanzoita zero.024 mm (zero.94 mils).Iyo foil inobatika, uye inogona kupetwa zviri nyore kana kuputirwa nezvinhu.Mapepa matete haana kusimba uye anombopota achinamirwa nezvimwe zvinhu zvinosanganisira mapurasitiki kana bepa kuti azvitungamirire kune zvine simba uye zvakanyanya kubatsira.
Aluminium foil yakatsiva tin foil mukati mepakati pezana ramakore rechimakumi maviri.MuUnited Kingdom neUnited States mamaira anowanzozivikanwa zvisina kurongwa se “tin foil”, semagaba esimbi anogara achinzi “magaba”).Mafirimu ane simbi anombokanganisa kune aruminiyamu foil, zvisinei iwo mafirimu epolymer akafukidzwa neganda rakatsetseka realuminium.MuAustralia, aluminium foil inozivikanwa zvakanyanya sealfoil.
Foil yakagadzirwa kubva pashizha rakatetepa rerata inove inowanikwa mukutengesa kare kupfuura imwe yayo aruminiyamu.Tin foil yakashambadzirwa zvekutengesa kubva panguva yakapfuura 19 kusvika kutanga kwezana ramakore rechi20.Izwi rekuti "tin foil" rinosara mukati memutauro weChirungu senguva yenguva pfupi yapfuura yealuminium foil.Tin foil hainyanyi kuumbika pane aruminiyamu foil uye inowanzopa kupfava kwetin kuravira kuchikafu chakaputirwa mairi.Tin foil yakatsiviwa kuburikidza nealuminium uye zvimwe zvinhu zvekuputira chikafu.

Aluminium foil ine inopenya chimiro uye matte side.Iyo inopenya facet inogadzirwa uku iyo aluminium inokungurutswa kwenguva yekusvetuka kwekupedzisira.Zvakaoma kugadzira rollers ine yekuvhura yekutanga-yero yakakwana kuti igone kubata nefoil geji, saka, pakupfuura kwekupedzisira, mapepa anopetwa panguva yakafanana, achipeta kaviri ukuru hwegeji pakuwana ma rollers.Apo mapepa anozoparadzaniswa gare gare, uriri hwemukati hauna kujeka, uye kunze kwemasuo pasi kunopenya.Musiyano uyu mukati mekupedzisira wakonzera pfungwa yekuti kurerekera divi kune zvakunoita paunenge uchibika.Nepo vazhinji vachibvumirana ne (zvisizvo) kuti dzimba dzakasarudzika dzinochengetedza kupisa kunze kana dzakaputirwa neyakagwinya kupedzisa kubata kunze, uye kuchengetedza kudziya mukati nekupenya kupedzisa kunobata nemukati, musiyano chaiwo hauonekwe pasina chiridzwa.Kuwedzera reflectivity kunoderedza kunyura kwega kwega uye kubuda kwemwaranzi.Foil inogona zvakare kunge iine isina-tsvimbo yekunamira pane yakapfava rimwe divi.The reflectivity of brilliant aluminium foil is 88% ukuwo dull embossed foil yakagadzirira 80%.
