What is the hot pocket sleeve for?

Online Answer
Here's why it works: The sleeve on the outside of a Hot Pocket is called a susceptor. It's made with a material that turns a microwave's electromagnetic energy into radiant heat. Instead of just steaming the food, the microwave acts like a broiler and will crisp bread instead of steaming it dry.
