When cooking milk in a meat oven (or kosher food in a treif one) I often find that when one wraps using aluminum foil, small holes appear (probably from the heat). I was wondering if anyone knows a better way to double-wrap food?

Have you tried the heavy duty aluminum foil? It is much thicker and may solve your problem. It may take a little longer for the food to heat up, however.
Also, check out this Q&A from Reynolds:
Why does aluminum foil sometimes melt and leave black specks on the food?
Occasionally when aluminum foil comes in contact with a different metal or a food that is highly salted or acidic, small pinholes are formed in the foil. This is a harmless reaction that does not affect the safety of the food. It is difficult to predict, but may occur under the following conditions:
When aluminum and a dissimilar metal are in contact in the presence of moisture, an electrolytic reaction may occur causing a breakdown of the aluminum. To avoid this use aluminum, glass, ceramic, plastic or paper containers. Do not cover sterling silver, silverplate, stainless steel or iron utensils with aluminum foil.
A similar reaction may occur when salt, vinegar, highly acidic foods or highly spiced foods come in contact with aluminum foil. The result of these reactions is a harmless aluminum salt. Some aluminum salts are used in medicines to treat stomach disorders. The food can be safely eaten; however, the aluminum salt particles can be removed from the food to improve the appearance of the food.
