Frequently Asked Questions

Does the container retain its shape and strength after cooking?
Yes, the container is rather heavy duty given the 3-ply nature of the product. It definitely retains shape before, during, and after cooking.

How can the container be cool to touch when it comes out of the oven?
It is cool to the touch because of its 3-ply nature. The center ply is a corrugated paper. This creates an air pocket between the inner baking layer and the outer layer that you would touch when removing from the oven. It is like a corrugated cup or a java jacket you would get with a cup of coffee. This is what creates the cool to the touch component. Also, paper does not retain very much heat.

Is the container suitable for the oven, microwave, and the freezer?
Yes, it is suitable for all three. The packaging is suitable for shipping and cooking frozen foods in either a microwave or an oven, as well as non-frozen foods.
