Summary:To provide packaged food exhibiting an excellent opening property together with fall resistance, that comprises a lid body exhibiting excellent gas barrier such as water vapor or the like, the body comprising a paper substrate.SOLUTION: According to a lid body 10 comprising a container body 12 whose opening is provided, that is formed with a flange, a functional layer 6 exhibiting a water-resisting property, a printing layer 5, a paper substrate 4, a support layer 2, and a heat seal layer 1 in this order; packaged food 40 according to an embodiment of the present invention comprises: a food packaging container 20 comprising a lid body heat-sealed by the flange via the heat seal layer, that covers the opening; and food 30 stored in the food packaging container. Mass of the paper substrate is larger than mass of any other layer included in the lid body. Fracture strength of the support layer is larger than peeling strength between the lid body and the container body. A heat seal portion between the lid body and the container body has a width of 2 to 12 mm. The peeling strength between the lid body and the container body is 4 to 32 N/15 mm.SELECTED DRAWING: Figure 1 【課題】紙基材を含み、水蒸気等のガスバリア性に優れた蓋体を備え、開封性及び耐落下性に優れた包装食品を提供する。【解決手段】本発明の実施形態に係る包装食品４０は、フランジが形成され、開口が設けられている容器本体１２と、耐水性を有する機能層６と、印刷層５と、紙基材４と、支持層２と、ヒートシール層１とをこの順序で含んだ蓋体１０であって、前記紙基材の質量は前記蓋体に含まれる他の何れの層の質量よりも大きく、前記開口を覆い、前記ヒートシール層を介して前記フランジにヒートシールされている蓋体とを備えた食品用包装容器２０と、前記食品用包装容器に収容された食品３０とを備え、前記支持層の破断強度は、前記蓋体と前記容器本体との間の剥離強さより大きく、前記蓋体と前記容器本体とのヒートシール部分の幅は２乃至１２ｍｍの範囲内にあり、前記蓋体と前記容器本体との剥離強さは４乃至３２Ｎ／１５ｍｍの範囲内にある。【選択図】 図１
