A peripheral edge part of a surface on the sheet side of the air permeable nonwoven fabric 6, and a peripheral edge part of a surface on the easy peeling layer side of the sheet are heat-sealed, and a storage part 8 is formed therebetween. The easy peeling layer 4 contains an ethylene copolymer whose melting point is 72-95°C. The air permeable nonwoven fabric 6 is a nonwoven fabric formed of a high-density polyethylene fiber.SELECTED DRAWING: Figure 1
【課題】包装体を開封したときに、包装体が密封されていたかどうかを容易に確認することができる包装体を提供すること。【解決手段】基材層２及び基材層上に設けられた易剥離層４を有するシート２０と、シート２０の易剥離層上に設けられた通気性不織布６と、を備える包装体１０。通気性不織布６のシート側の面の周縁部と、シートの易剥離層側の面の周縁部とが熱融着されて、これらの面の間に収容部８が形成されている。易剥離層４が、融点が７２〜９５℃のエチレン共重合体を含有する。通気性不織布６が、高密度ポリエチレン繊維の不織布である。【選択図】図１ |
