Stan asks,

We have a customer who wants to bake a cake in our corrugated box. We use recycled paper from XXXXXXXXXX Mill in XXXXXXX. We also have a letter of ‘No Objection’ from Health Canada. Do you foresee any problem or restriction on this method of cake preparation?

Assuming you have some type of suitable and accepted barrier coating the only other concern would be heat. I assume that they are planning to bake in a conventional or convection oven. Since cakes typically bake at 350 degrees F you shouldn’t have to worry about the 451 degree combustion point of the paper.

If a microwave oven is to be used then there may be a few concerns about the paper and what comes into direct contact with it. A mass resting against paper in a microwave can cause temperatures to reach a point significant enough to cause scorching and even combustion of the paper. (I’ve ruined enough bags of pop corn to prove this point)

I’m not sure how the AIB may play into this if the products are to ship into the United States.

Let’s toss this one out to the readers and see what knowledge they have to share.
