ABSTRACT:
A microwave oven door structure has a rectangular panel with many holes therethrough formed all over its surface. Two transparent films cover it through adhesive layers from both sides. One of the films covers the panel completely but the other film covers only partially the holes near one or more peripheral regions and the adhesive layer on the same side surrounds each hole discontinuously such that air in the holes, when heated and expanding, can freely move out of the structure.
