<p>PROBLEM TO BE SOLVED: To usually sufficiently satisfy various properties such as excellent heat resistance, gas barrier property, and seal strength which are required by a food packaging bag, and excellently and safely exhaust steam to be generated at the time of heating and cooking when the food housed in the bag is to be heated and cooked by a microwave oven together with the packaging bag. SOLUTION: A bag body 1 is formed by using a heat adhesive synthetic resin film 1a having tear cut property in a fixed direction. A band-like nonwoven fabric 2 is arranged along the tear cut direction of the film 1a in the bag body 1. Both end parts of the fabric are pinched by the film 1a at a heat seal section of the peripheral edge of the bag body 1 so as to integrally seal with heat, so that the nonwoven fabric 2 is fixed. Further, the film 1a and the peripheral edge of the nonwoven fabric 2 are sealed with heat and a tab 5 is formed at a position corresponding to the end part of the nonwoven fabric 2.</p> |
