Abstract
A sandwich pouch is formed from a unitary blank of Kraft paper or other easily biodegradable, flexible sheet material. The blank is of generally rectangular form and includes a plurality of generally rectangular panels, joined side by side and foldably secured together by generally transversely extending fold lines. The ends of a pair of middle panels are each provided with a generally rectangular end seal flap. The blank is also provided with a pair of longitudinally extending tear lines which permit the pouch formed from the blank to be torn open at either or both ends to gain access to its contents. The pouch is opened by bending back an upper front closure panel for insertion of a food product such as a hamburger.
