Document Type and Number:
Japanese Patent JP2015113131
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a packaging bag capable of effectively suppressing the blowing-out of a content due to heating even in a state of being placed horizontally in a microwave oven.SOLUTION: A packaging bag 1 is made by heat-sealing stacked laminate films 10 and includes a storage space 2 in which a content is stored and a pressure accumulation chamber 3 in which a content is not stored. The packaging bag 1 includes a marginal seal part 40 formed by heat-sealing a marginal part 12 of the layered laminate films 10, and a point seal part 50 for surrounding the pressure accumulation chamber 3 and isolating it from the storage space 2. A cut line 60 is formed in a portion surrounded by the point seal part 50 of each of the laminate films 10 that constitute the pressure accumulation chamber 3. The extension direction of the cut line 60 intersects with an extension direction of a part of the marginal seal part 40 to which the cut line 60 is closest.
