Abstract
A microwave susceptor material packaging article or ovenware comprises at least two distinct areas of susceptor materials with an inner susceptor material area and an outer susceptor material area with the inner surface having an ability to convert more microwave energy to heat (on a basis of equal inner and outer surface areas and equal amount of striking microwave energy).
Claims31
In an article suitable for heating a food by microwave energy comprising a substrate supporting susceptor material for converting microwave energy to heat wherein the improvement comprises susceptor materials present in two distinct areas:
- a first area and
- a second area,
- wherein a line of demarcation exists between the first area and the second area with the first area at least substantially surrounded by the second area, with the requirement that the first and second areas are completely covered with susceptor material and
- wherein on the basis of equal surface areas and an equal amount of microwave energy striking the surfaces the first area converts more microwave energy to heat in comparison to the second area.
A method of heating a food product comprising subjecting the food product to microwave energy wherein the food is supported by susceptor materials present in two distinct areas,
- a first area and
- a second area,
- wherein a line of demarcation exists between the first area and the second area with the first area at least substantially surrounded by the second area with the requirement that the first and second areas are completely covered with susceptor material and
- wherein on a basis of equal surface areas and an equal amount of microwave energy striking the surfaces the first area converts more microwave energy to heat in comparison to the first area.
A food packaging article comprising:
- (a) a substrate
- (b) a susceptor material positioned on the substrate with the susceptor present in two distinct areas,
- a first area and
- a second area,
- wherein a line of demarcation exists between the first area and the second area with the first area at least substantially surrounded by the second area, and wherein on the basis of equal surface areas and an equal amount of microwave energy striking the surfaces the first area converts more microwave energy to heat in comparison to the second area with the requirement that the first and second areas are completely covered with susceptor material,
- (c) a food positioned on the susceptor material and optionally
- (d) a covering surrounding a surface of the food.
A method of making a food support packaging article comprising the steps of:
- (a) applying to a substrate a susceptor material present in two distinct areas,
- a first area and
- a second area,
- wherein a line of demarcation exists between the first area and the second area with the first area at least substantially surrounded by the second area with the requirement that the first and second areas are completely covered with susceptor material and wherein on a basis of equal surface areas and an equal amount of microwave energy striking the surfaces the first area converts more microwave energy to heat in comparison to the first area,
- (b) positioning a food product on the susceptor material
- (c) applying a wrapping on the food.
A method of preparing a food packaging article comprising:
- (a) applying to a substrate a layer of susceptor material with a susceptor material present in two distinct areas,
- a first area and
- a second area,
- wherein a line of demarcation exists between the first area and the second area with the first area at least substantially surrounded by the second area with the requirement that the first and second areas are completely covered with susceptor material, and wherein on the basis of equal surface areas and an equal amount of microwave energy striking the surfaces the first area converts more microwave energy to heat in comparison to the second area,
- (b) positioning a food product on the susceptor material
- (c) applying a covering to surround the food product on a surface which does not face the susceptor material.
