that is really interesting…. is Reynolds Wrap an aluminium foil or what?? We don’t have Reynolds in Australia…

How much % of aluminum is in Reynolds Wrap and how much is paper and other products?

Have you heard of eco-friendly magnets? As far as I know they are made from alloys, which are of course mined, but some factories say they pass an environmental protection standard and/or have recycled magnets. Has anyone heard of this?

So you’re saying that they use raw bauxite so they can precisely control the alloy composition for optimal ductility for food wrap? (I am assuming Reynolds can control gauge with their process.)

Why can’t they do that with recycled Al? What non-separable impurities interfere with the desired ductility?

The purity required for various forms/grades of aluminum relates to the chemical properties of the metal (and its intended end use). The % of aluminum content does not relate in any way to ‘food save’ purity level. In other words, most aluminum foil (because of its ductility, gauge and performance requirements) requires high purity aluminum. Can stock has different properties and is more readily recycled. Both Stuart and Lisa came from the aluminum industry and have worked with many food industry firms. We did not speak to anybody for this article. LAR

Hmm, so the recycled aluminum we have been using for decades in soda cans is not ‘food-safe’ purity level?

Have you talked to any other aluminum users in the food industry besides Reynolds?
