Abstract
A flexible paper popcorn package in the form of an easily expandable bag (18) is disclosed including a bottom wall (20), a top wall (22), first and second, pleated, side walls (26), a first non-opening end (24), and a second, peelable end (28). The ends (24, 28) are sealed by constant width adhesive strips (46, 48) located on the inside surfaces of the sheet (42) forming the tubular stock for the bag (18) and which adhere the inside surfaces of the pleats (26a-d) to the top and bottom walls (20, 22) and adhere the top and bottom walls (20, 22) together intermediate the inner edges of the pleats (26a-d). The outside surfaces of the pleats (26a-d) are bonded together by constant width tuck strips (50) extending from the inner edges of the pleats (26a-d) towards but substantially spaced from the outer edges of the pleats (26a-d) connected to the top and bottom walls (20, 22) and overlain by the adhesive strip (46) of the first end (24) for ensuring that the first end (24) does not vent by releasing the adhesive strip (46) while the popcorn kernels are popping in the microwave oven.
