You can always take a sacrificial tape and bake it (a
little hotter
than you'd expect you'd need on a data tape) to see how well it fares.
Something about baking. Beware of raidiative heat.
An oven heating up can possibly generate *large* temperatures in objects
absorbing the energy in a direct light path from the coils. If you want a
certain low temperature, heat the oven up first, then turn it off and leave
it off while the item is in it. Possible you can avoid direct radiation
burns by putting the item in a container, something not tried by me at
least.
May sound bizarre, but bottomline this as:
"Warning, an oven set for 180 deg. can melt plastic when turned on."
