Microwaveable package for food products
A susceptor includes a flexible substrate and a metallic material provided on at least one surface of the substrate. A first plurality of ventilation apertures are formed in the substrate and the metallic material, and the first plurality of ventilation apertures are configured to permit a fluid to pass through the substrate and the metallic material.
1. A susceptor comprising:
a flexible substrate; and
a metallic material provided on at least one surface of the substrate;
wherein a first plurality of ventilation apertures are formed in the substrate and the metallic material, and the first plurality of ventilation apertures are configured to permit a fluid to pass through the substrate and the metallic material;
wherein the first plurality of ventilation apertures are provided in substantially rectangular-shaped groups of generally parallel slits, the orientation of the parallel slits varying by about 90 degrees between adjacent groups of parallel slits.
2. The susceptor of claim 1 wherein the substrate defines an interior portion, and the ventilation apertures are configured to permit steam to escape from the interior portion.
3. The susceptor of claim 1 wherein the ventilation apertures comprise a plurality of substantially parallel slits.
4. A susceptor comprising:
a flexible substrate; and
a metallic material provided on at least one surface of the substrate;
wherein a first plurality of ventilation apertures are formed in the substrate and the metallic material, and the first plurality of ventilation apertures are configured to permit a fluid to pass through the substrate and the metallic material; and
a support layer coupled to the substrate, the support layer comprising a second plurality of substantially parallel apertures oriented at approximately 90 degrees relative to the first plurality of ventilation apertures.
5. The susceptor of claim 1 wherein the metallic material comprises a conductive ink.
6. The susceptor of claim 4 wherein the conductive ink comprises graphite.
7. The susceptor of claim 1 wherein the metallic material is provided on a first surface and a second surface of the substrate.
8. The susceptor of claim 1 wherein the substrate comprises a thermoplastic material.
9. The susceptor of claim 7 wherein the thermoplastic material is one of polyethylene terephthalate (PET), polyetheretherketones (PEEK), and polytetrafluoroethylene (PTFE).
10. The susceptor of claim 7 further comprising:
a second metallic material provided on a surface of the thermoplastic substrate opposite the first metallic material;
a polymer outer layer coupled to the first metallic material opposite the substrate, and
a polymer inner layer coupled to the second metallic material opposite the substrate;
wherein the first metallic material, the second metallic material, the outer layer, and the inner layer provide an integrated, double-layer susceptor.
