<P>PROBLEM TO BE SOLVED: To provide a sealed bag to be heat-cooked in a microwave oven with which steam is discharged without a base material film broken as a V-shaped heat-sealed part interlaminarly delaminates to the end or it cohesively fails and delaminates. <P>SOLUTION: A means for discharging the steam before the bag swells and gets broken is provided on a steam level position heat-sealed part. The steam discharging means consists of the V-shaped heat-sealed part and a steam vent for connecting the inside and the outside of the bag before delamination of the V-shaped heat-sealed part reaches an inner rim of a heat seal. The steam level position heat-sealed part has heat seals overlapped or heat-sealed at a high temperature. In addition, the V-shaped heat-sealed part is heat-sealed with a smaller number of times or at a lower temperature than the steam level position heat-sealed part, and has an ink layer formed on an adhesive surface of a sealant film of a laminate film on at least one of sides corresponding to at least the V-shaped heat-sealed part. <P>COPYRIGHT: (C)2007,JPO&INPIT |
