Summary:To provide a package for microwave oven which is excellent in both heating property and opening property, while using a paper material container.SOLUTION: A package for microwave oven which is for storing a content in a sealed state includes: a film-like lid part; and a container sealed by the lid part. The container is constituted by a paper material layer and a resin layer bonded to the paper material layer being laminated. The container includes: a container body formed in a concave-like shape, and capable of storing a content; and an annular flange part provided so as to extend outward from an upper end of the container body. At the flange part, a heat-seal part is provided in which the flange part and the lid part are heat-sealed. The heat-seal part is provided across the whole circumference of the flange part. The heat-seal part includes a steam discharge part for discharging steam generated by heating the contend in a microwave oven. The steam discharge part is constituted by curving part of the heat-seal part in an inner edge direction of the flange part. Peel strength between the lid part and the container at the steam discharge part is 100-320 kgf.SELECTED DRAWING: Figure 1 【課題】紙素材製容器を用いつつ、加熱性と開封性の両方に優れた、電子レンジ用包装体を提供する。【解決手段】本発明によれば、内容物を密封状態で保存するための電子レンジ用包装体であって、フィルム状の蓋部と、前記蓋部によって密封された容器を備え、前記容器は、紙素材層と、前記紙素材層に接着された樹脂層が積層されて構成され、前記容器は、凹状に形成され内容物を収容可能な容器本体と、前記容器本体の上端から外方に延出するように設けられた環状のフランジ部を有し、前記フランジ部には、前記フランジ部と前記蓋部が熱溶着された熱溶着部が設けられ、前記熱融着部は、前記フランジ部の全周に渡って設けられ、前記熱融着部は、前記内容物を電子レンジで加熱することによって発生する蒸気を排出するための蒸気排出部を備え、前記蒸気排出部は、前記熱溶着部の一部を前記フランジ部の内縁方向に湾曲させて構成され、前記蒸気排出部での前記蓋部と前記容器の間の剥離強度が１００～３２０ｋｇｆである、包装体が提供される。【選択図】図１
