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