Biodegradable microwave susceptor

A construct for heating a food item in a microwave oven, comprising:

• a plurality of panels arranged to define a space for the food item, wherein at least one panel of the plurality of panels has a surface exposed at least partially to the space, wherein the surface includes a microwave susceptor;
• and
• a fold area between a first panel and a second panel of the plurality of panels;
• and
• wherein the microwave susceptor comprises:
• a biodegradable substrate comprised of a biodegradable thin film;
• and
• a susceptor layer attached to the biodegradable substrate, wherein the susceptor layer comprises at least one area of microwave interactive material and at least one area devoid of microwave interactive material, and wherein the at least one area devoid of microwave interactive material corresponds to the fold area.

A construct for heating a food item in a microwave oven, comprising:

• a bottom panel having a first longitudinal edge, a second longitudinal edge opposite of the first longitudinal edge, an inner surface and an outer surface, wherein the inner surface is comprised of a first portion that is adapted to be in contact with the food item;
• a first side panel extending upwardly from the first longitudinal edge of the bottom panel, the first side panel having an inner surface and an outer surface;
• and
• a second side panel extending upwardly from the second longitudinal edge of the bottom panel, the second side panel having an inner surface and an outer surface;
• wherein the bottom panel, the first side panel and the second side panel form a U-shaped structure defining an interior space for receiving the food item;
• a biodegradable substrate comprised of a biodegradable thin film;
• and
• a susceptor layer positioned between the inner surface of the bottom panel and the biodegradable substrate, wherein the susceptor layer has a pattern;
• wherein the pattern of the susceptor layer comprises a plurality of microwave interactive areas isolated from each other by a plurality of microwave inactive areas, wherein the plurality of microwave interactive areas are each comprised of a microwave interactive material, and wherein each of the plurality of microwave inactive areas are devoid of microwave interactive material;
• wherein the pattern of the susceptor layer is selected to prevent scorching and burning of the biodegradable substrate;
• and
• wherein a fold area exists between the bottom panel and the first side panel and wherein an area of the susceptor layer corresponding to the fold area is devoid of microwave interactive material.

A blank for forming a microwave heating construct, the blank comprising:

• a plurality of adjoined panels, wherein the plurality of adjoined panels comprise a first panel, a second panel joined to the first panel along a first fold area and a third panel joined to the second panel along a second fold area;
• and
• a microwave susceptor attached to an inner surface of the first panel comprising:
• a biodegradable substrate comprised of a biodegradable thin film;
• and
• a susceptor layer attached to the biodegradable substrate, wherein the susceptor layer comprises at least one area of microwave interactive material, a first area devoid of microwave interactive material, and a second area devoid of microwave interactive material, wherein the first area devoid of microwave interactive material corresponds to the first fold area and wherein the second area devoid of microwave interactive material corresponds to the second fold area.
