Abstract
A microwave packaging made of a flexible, heat-sealable laminate has a grid structure made of electrically non-conductive cells that do not absorb microwaves, and an electrically conductive metal grid that separates the cells from one another. The metal grid has a layer thickness of at least 1 μm, and the cells each have a size between 100 mmand 1200 mm. The proportion of the non-conductive area formed by the cells amounts to at least 50% of the total area. A liquid-tight outer film follows a first side of the metal grid directly or by way of at least one connecting layer, and a moisture-absorbent layer follows a second side of the metal grid directly or by way of at least one intermediate layer, and has a polymer base substance and extends essentially over the entire area of the laminate. The microwave packaging is formed from the laminate by heat-sealing.
