Why are the aluminum foil sheets used at deli counters patterned (with dimples, crosshatches, diamonds, &c.)? Is patterned foil available in roll form?

I suspect the dimpling creates insulating air pockets that keep food warmer longer.

to look pretty?
if it's not just embossed, but actually a variation in thickness, then it may make the foil tougher, like the thicker threads in rip-stop nylon.
pmbuko - i couldn't find any foil on that link.

It's pretty. The foil is possibly less likely to stick to one another. It may reduce the amount of material required; the stamping makes it thinner. It's pretty. And it prevents re-use as technology against alien mind rays, lest employees start selling it on the black market.

This would make a very good Straight Dope question.

hmm. maybe, since delis and grocery stores buy in bulk, the holes = less aluminium = less cost? maybe?

I went out to lunch after seeing this question and at the taqueria I went to noticed that they had a whole industrial roll of foil in a white box with the label "patterned foil." So, yes, it does come in rolls although that doesnt answer the why.

Also, this site seems to imply that they are merely decorative.
