To provide a technique capable of effectively holding freshness of garden stuff.SOLUTION: A freshness holding bag 100 comprises: a bag main body 10 which is formed in a cylindrical shape by sticking both ends of a synthetic resin film, then closing one end, and stores garden stuff; and a back lining part 20. The back lining part 20 comprises a communication region 30 for communicating the outside and inside of the bag main body 10, and satisfies the following condition a. (Condition a) When a dyeing solution including an organic solvent and mineral oil is brought into contact with an external part end part of the bag main body 10 of the communication region 30, and when measuring a period (t seconds) required for the dyeing solution to reach an inside part end part of the bag main body 10 of the communication region 30 from the outside part end part of the bag main body 10 of the communication region 30 by capillarity, t is 0.6 to 3.SELECTED DRAWING: Figure 1 【課題】青果物の鮮度を効果的に保持できる技術を提供する。【解決手段】本発明の鮮度保持袋１００は、合成樹脂フィルムの両端を貼り合わせて筒状にし、一方を閉じることで得られた青果物を収容する袋本体１０と、背貼り部２０と、を備え、背貼り部２０は、袋本体１０の外部と内部とを連通する連通領域３０を有し、以下の条件ａを満たす。（条件ａ）有機溶剤および鉱油を含む染色液を連通領域３０の袋本体１０の外部側の端部に接触させ、当該染色液が、毛細管現象により、連通領域３０の袋本体１０の外部側の端部から、連通領域３０の袋本体１０の内部側の端部に到達するまでに要する時間（ｔ秒）を測定したとき、ｔが０．６～３となる。【選択図】図１
