Microwave oven window having a microwave-blocking screen, an interior plastic film and a pressure-sensitive adhesive layer bonding the plastic film to the screen over the full area of the screen but substantially not penetrating into the openings of the screen.

Microwave oven window

Microwave oven window comprising two transparent panels, an intermediate microwave-blocking screen and a transparent thermoplastic adhesive filling the space between the panels. The interior panel is very thin and the thickness of the thermoplastic adhesive panel barely exceeds that of the screen. The thinness of the interior panel plus adjacent adhesive minimizes the leakage of microwaves.
