I beg to differ with you on one point. Rubbing alcohol is not the
same as drinking alcohol. Drinking alcohol is ethanol. Rubbing
alcohol is isopropanol, which is quite bad for humans to ingest.
Almost-pure ethanol is available (Ever-Clear), and can be drunk, but
is not rubbing alcohol.

But, yes, plastic won't be affected by alcohol in a cake.
Polyethylene does not leach into food the same as other plastic wraps,
but it is mainly heat and fat that cause the leaching.
