ABSTRACT:
A sealed bag for microwave heating composed of a film having a fusing layer inside, said bag being sealed by fusing both sides of said film longitudinally with each other and both ends thereof laterally, wherein both sides of the film are turned outside to form two rows or turned-up faces, a turned-up line formed by said two rows of turned-up faces is covered with an easily openable fusing tape having an easily openable film inside and reinforced with a base material outside, said tape being fused with the turned-up faces of the film, and at least one end of the fusing tape not fused by a length which can be taken with fingers is left as a pick-up flap in the laterally fused area. When cooked food for a few people is hermetically packaged in this sealed bag and heated with a microwave oven, the bag is not broken until the internal temperature thereof approaches 100.degree. C. and is slightly opened when the inside thereof is sufficiently filled with water vapor, thereby discharging water vapor, and the separation of the tape after the completion of heating permits the contents to be easily taken out.
