PROBLEM TO BE SOLVED: To provide a technology that suppresses variations in degree of garden stuff deterioration caused by a change in preservation condition.SOLUTION: A packaging bag for preserving freshness of garden stuff is made of a perforated synthetic resin film. A hole 14 is provided in the synthetic resin film 2. When Tmax represents the maximum thickness of the perforated synthetic resin film in an area within a distance of 10 mm from an outer periphery of the hole 14 and Tmin represents the minimum thickness thereof, the ratio Tmax/Tmin between the maximum thickness and the minimum thickness is in the range of 1.05-8.00, on the outer surface of the packaging bag for preserving the freshness of the garden stuff.COPYRIGHT: (C)2015,JPO&INPIT【課題】保存条件の変化によって生じる青果物の劣化度合いのバラつきを抑制する技術を提供する。【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、合成樹脂フィルム2には孔14が設けられており、青果物鮮度保持包装袋の外表面において、孔2の外周から10mm以内の領域における有孔合成樹脂フィルムの最大厚みをTmax、最小厚みをTminとして、最大厚みと最小厚みの比Tmax/Tminが、1.05以上8.00以下である青果物鮮度保持包装袋。【選択図】図2
