Wasn't it a think that "stuff" dies on exposed metal?
replyI think it's the high-heat manufacturing process which kills all microbes. Spores would be unaffected by aluminium foil, so it's defo something else like heat is my thoughts - basically being sterilised during manufacturing.
replyany tips on how to reliably get that "thicker gauge" one? I've been craving it since maybe 20y ago when I got a roll from my old stint in a restaurant. I've tried buying some rolls by "heavy duty" labels and these days it's just as likely to be one of those thin "look at it funny and it tears".
replyCostco sell two different types of foil, one is shorter and has blue packaging and the other is longer and has red packaging... It's the red one which is much thicker.
replyI had no idea about that!
