Abstract
A microwave heating material and method of forming thereof is presented. In accordance with the present invention, a pre-selected metallized pattern is disposed on at least a portion of a dielectric material using a transfer process, preferably a hot stamping transfer process in conjunction with very thin metal, preferably aluminum roll leaf. The roll leaf can be easily hot-stamped in any variety of patterns such as dots, spirals, circles or any other desired pattern onto disposable or reuseable trays, flexible wraps, rigid substrates or any other suitable dielectric material. Such a transfer process is relatively inexpensive both in terms of labor and other costs.
Claims23
A method of making microwave heating material for heating an object comprising the steps of:
- obtaining a dielectric substrate material which permits microwave energy to pass threrethrough and into an object to be heated;
- forming a pre-selected metallized pattern on at least a portion of said dielectric substrate material by a transfer process whereby said metallized pattern converts microwave energy to short wave heat energy during microwave heating of said dielectric substrate material and whereby said short wave heat energy is transferred to the object to be heated;
- providing a non-metallic protective layer on said metallized pattern whereby direct contact between said metallized pattern and the object to be heated is precluded.
