Bake out of the box. You need air circulation around the tape
for optimum dehydration and uniform temperature exposure.
I use a Yamato oven with a small computer fan to stir the air.
I separate the tapes with a 1/4-inch spacer to get good
circulation around the tapes. I run batches of 10-12 on
average. Your project is 6-8x bigger than my typical project,
so you probably need a capacity of 60-90 tapes per batch.
This is not to say that baking in the box is not possible.
But my concern is that if there is moisture in the box itself
you might be "steaming" the tape rather than dehydrating the
If baking in the box requires prolonged baking times - say an
extra 1-2 hours - that extra 1-2 hours spent baking might be
better used boxing/unboxing tapes rather than exposing the
tape to longer heating cycles than absolutely necessary.

Subject: [ARSCLIST] baking tape
Has anyone tried to bake tapes in the boxes? I usually bake them outside
the boxes but now I have about 15,000 tapes to bake and taking them out
of the boxes and putting them back in will be time consuming and could
make for a switch between boxes and tapes. What do you think?
