nkt Posted September 22, 2005 Report Share Posted September 22, 2005 Hi all. Something I've been idly pondering the last five minutes: Some drinks cans are steel, but most are aluminium. And all food cans are steel. (Most (All?) are lined with something as a barrier material, too) Why is this? Obviously steel is cheaper than Aluminium, but harder to form. However, by now you would think that one type would have won completely. Thoughts? Turtle 1 Quote Link to comment Share on other sites More sharing options...
goku Posted September 22, 2005 Report Share Posted September 22, 2005 i'm not sure, but i think steel cans are used when the contents need to be heated prior to sealing Quote Link to comment Share on other sites More sharing options...
nkt Posted September 22, 2005 Author Report Share Posted September 22, 2005 I know they use steel food cans like that, but I doubt they boil coke or pepsi (aluminium cans) or tango (steel cans) as they are carbonated, and heating a stamped thin steel container you can tear apart with one finger seems risky.

I don't know if this is really the case though as I've seen little aluminium cans of sausages & soup.___Maybe an E-Mail to Kraft or some other food manufacturer? It's a good question. :rolleyes: :) :hihi: Quote Link to comment Share on other sites More sharing options...
