Abstract:
1. A packaged microwaveable food product comprising a frozen block of food formed of raw protein and a liquid sauce, said frozen block sealed in a cooking pouch formed from a multilayer elongated sheet having a predetermined width defining free width edges, the width transverse to the sheet length, said sheet comprising an outer paper layer with a water-repellent coating thereon, a plastic coating inner layer and a partially-metallized layer between the paper outer layer and the plastic coating inner layer, wherein said partially-metallized layer comprises a completely metallized central section located substantially centrally in the sheet and having a width less than the dimension of the frozen block, a pair of partially metallized sections lying one on either side of the completely metallized central section, each partially metallized section having a width sufficient to extend around the edge of the food block and overly the top of the food block, each of said partially metallized sections having a substantially uniform metallized coverage pattern between 40% and 60% of the overall area of each partially metallized section, and a pair of completely unmetallized edges extending from the pair of partially metallized sections to the free width edges of the sheet, wherein said pouch is formed by placing the frozen block upon the completely metallized central section with the edges of the block overlying portions of the partially metallized section, folding the sheet around the block such that the partially metallized sections lie adjacent the edges of the block and overly the top of the block, sealing the unmetallized edges together to form a fin seal, cutting the wrapped sheet transversely to form opposite ends of the pouch and sealing the ends transversely to form opposite end seals.
