Canning Homebrew

umm, I don't think so

Brewing Science and Practice:

The two-piece can is manufactured from a coil of plate, which is unwound, lubricated
and fed into a blanking press (Scruggs, 1997), which forms the sheet into shallow cups.
These cups proceed to an ironing press to form the side wall of the can. More metal is
retained at the top and bottom of the can for strength but in the side wall the thickness
will be only 0.09 mm. The subsequent strength of the filled can relies on the internal
pressure of the beer in the can. Trimming follows ironing to ensure uniform height.
During these processes the can is covered with lubricant that is removed with sprays.
External decoration on the can is applied by a rotary machine using inks and/or varnishes,
which are stabilized by baking. Internal coatings are applied by an airless stationary
spray-gun and the cans are then baked again to cure the coating and remove solvent.

I'm pretty sure all cans are plastic lined, be it coke or VB.

umm, I don't think so

Yes they are champ - I'm glad you mentioned coke and VB also - those are both featured in the photo.

"The can form is washed several times to remove dust and lubricant before printing and lacquering on the outside, and coating the inner walls with a resistant polymer."
