PACKAGING BAG FOR RETAINING FRESHNESS OF VEGETABLE AND FRUIT, PACKAGE CONTAINING VEGETABLE AND FRUIT USING THE SAME, AND METHOD FOR RETAINING FRESHNESS OF VEGETABLE AND FRUIT
PROBLEM TO BE SOLVED: To suppress stably deterioration or decay of vegetables and fruits.SOLUTION: In a packaging bag for retaining freshness of vegetables and fruits constituted of a perforated synthetic resin film, a value of a rate of change of an aperture calculated from area ratio R1(%) of the aperture at 40°C of the perforated synthetic resin film and area ratio R2(%) of the aperture at 5°C of the perforated synthetic resin film according to the following formula (1) is 5 or higher and 50 or lower. Formula: the rate of change of aperture={(R1-R2)/R2}×100 (1).SELECTED DRAWING: None【課題】青果物の劣化または腐敗を安定的に抑制する。【解決手段】有孔合成樹脂フィルムから構成された青果物鮮度保持包装袋であって、前記有孔合成樹脂フィルムの４０℃における開孔面積比率Ｒ１（％）と、前記有孔合成樹脂フィルムの５℃における開孔面積比率Ｒ２（％）と、から下記式（１）で算出される開孔変化率の値が、５以上５０以下である、青果物鮮度保持包装袋。 式：開孔変化率＝｛（Ｒ１－Ｒ２）／Ｒ２｝×１００ （１）【選択図】なし
