Aluminium kan de ɔlsay — frɔm yu fav soda to ɛnaji drink ɛn tin kol brij. Bɔt yu no se ɛni wan pan dɛn aluminiɔm drink tin dɛn ya kin ayd sɔntin we pɔsin nɔ go si insay? Nɔto jɔs mɛtal de ol yu drink. Wan tin layt de pan plastic — ɛn i de ple wan big pat pas aw bɔku pipul dɛn kin no.
Dis atikul de tɔk bɔt wetin mek dɛn layn aluminiɔm kan dɛn wit plastic, us matirial dɛn de yuz, if i sef, ɛn wetin dis min fɔ risaykul ɛn yu wɛlbɔdi.
Pan ɔl we aluminiɔm kin luk klin ɛn i tan lɛk mɛtal na do, insay bɔku pan di tin dɛn we dɛn kin put insay tin dɛn, dɛn kin put klia ɔ smɔl tin we dɛn kɔl epoxy coating. dis ultra-tin film — we tik jכs 1 to 10 maykron — dεn de spεray am insay di tin fכ fכm wan prכtektiv barεri bitwin di mεtal εn di drink.
Insay di kan industri, dɛn kin kɔl dis 'lak', ɛn dɛn kin mek am wit tin dɛn we dɛn mek wit plastic lɛk ɛpoksi rɛsin, vaynil, ɔ akrilik. Pan ɔl we dɛn nɔ kin si am ɛn bɔku tɛm dɛn nɔ kin pe atɛnshɔn to am, dis kɔtin na wan pan di pat dɛn we dɛn mek wit injinia pas ɔl na wan standad tin.
Fɔs, aluminiɔm kin tan lɛk wan strɔng, nɔ-riaktiv mɛtal — pafɛkt fɔ pak it ɛn drink. Bɔt fɔ tru, aluminiɔm gɛt kemikal dɛn we rili de wok, mɔ we i kam nia sɔm asid dɛn, sɔl dɛn, ɛn tin dɛn we dɛn kin yuz fɔ mek tin nɔ pwɛl we dɛn kin si na di drink dɛn we dɛn de drink tide ɛn it dɛn we dɛn dɔn prosɛs.

Fɔ mek ɔl dis nɔ apin, di wan dɛn we de mek am kin put wan tin we dɛn kɔl plastic kɔtin, we dɛn kin kɔl bak lak, pan di insay wɔl dɛn na aluminiɔm tin dɛn we dɛn kin yuz fɔ mek tin dɛn . Dis layt de ple plɛnti impɔtant rol dɛn — nɔto jɔs wan. Lɛ wi brok dɛn dɔŋ:

Bifo dat, di industri de abop pan ay-pafɔmɛnshɔn kɔtin dɛn, we de gi fayn protɛkshɔn pan smɔl pat pan di matirial ɛn kɔst. Dɛn kɔtin ya de mek am pɔsibul fɔ yuz ɔlta-layt, tin-wɔl aluminiɔm, we de kɔntinyu fɔ de fɔ lɔng tɛm nɔmɔ bikɔs ɔf di layna we de insay.

Ɔl dis de ɔndaskayn di tru tin se di intɛriɔ kɔtin nɔto trivial ad-ɔn, bɔt na wan kɔr kɔmpɔnɛnt fɔ di mɔdan aluminiɔm drink kan dɛn — we impɔtant fɔ dɛn wok, sef, ɛn kɔmɛshɔnal viability.
