ABSTRACT:
A pattern of tear perforations is provided in the substrate that forms a microwave reheating support. The pattern of tear perforations enables the substrate to be separated into portions so that the substrate can be adjusted in size and/or shape to correspond to the size and/or shape of the food product being heated. For example, a round substrate can include a circular pattern of tear perforations spaced radially inward from an outer circumference of the round substrate. This enables the outer peripheral portion of the round substrate to be removed to reduce the size (diameter) of the substrate for use with smaller-sized food products. The pattern of tear perforations can include one or more lines of tear perforations that extend across a substrate. For example, the lines of tear perforations can divide the circular substrate into a plurality of wedges that can be used, for example, to heat a slice of pizza instead of the entire pizza. Additionally, the line(s) of tear perforations can divide a box or sleeve, which may contain multiple food products (spring-rolls, for example) into individual supports (boxes or sleeves), each containing a single food product.
