Alternative source for ribbon Foil.

HI ALL

I've been searching for thin alum foil for my ribbon project.
To date the thinnest i've found locally has been some cheap and nasty kitchen foil. it feels thinner than some of the more expensive brands..
However my eye was caught tho the day by some foil that appeared thinner.

The source : A Lindt chocolate block....the wrapper withing seemed very interesting.

I wonder if anybody out there has a micrometer than they can measure this stuff with...

It also has the advantage of being pre embossed- but with the Lindt logo.

Nothing to lose here in trying, if its no good for ribbon speakers the product is pretty good.

The type i refer to is from the range that has Chili chocolate.
The size of the ribbon one could construct would be limited to about 200mm,

Currently I'm eyeing off one of the mega-size boxes of Toblerone for R & D

Cheers

Today at the supermarket i thought it about again and had to get some Lindt Edelbitter Mousse Hot Granataple Chili.(2.70 Euro 150 gr.)
With my el Cheapo Digital Caliper i got 0.48 to 0.56mm for a 32 times fold. So, my foil seams to be 0.015 to 0.0175 mm in thickness.
I had to buy mine in Germany - the Foil may be different in other regions.

Capacitor Materials, Specializing in Metallized Films, Aluminum Foil and Tin Foil

chances are you could find a cheap aluminum foil capacitor and un-roll it.

Thanks Fonebones
Iterestingly the Lindt foil appears to be some 4 times the thickness of that claimed to be used by the likes of LCY etc.

Hi All
I've got my hands on a measuring gizmo
and measuring the cheapest kitche foil I could find have come up with 0.008mm thickness-
compared to about 0.004 to 0.006mm for some of the LCY's ( I think)

not to far off the mark i thinks.. and available in long lengths

BTW the brand of the foil here in Australia is "Black and Gold"

Hope this helps

btw thickness was 0.086 inches for 256 thicknesses of foil,
please feel free to check my calcs..

Hi,
.008mm comes out to about .3mil which sounds about right for some of the thinnest that I have been able to find over here in the states as far as kitchen foil goes.

Commonly it is around .5mil for the regular stuff and between .75mil to 1mil for the heavy duty brands.
