Abstract

シート製造後も経時変化が小さく安定的な柔軟性を備え、微生物などによる分解も可能で、使用後、廃棄処分がしやすい環境適合性に優れた生分解性のシート、フィルムを提供する。生分解性（３ＨＡ）共重合体からなるシートであって、式（１）：｛（製造から１日間経過後の引張り伸び率（％）－製造から３０日間経過後の引張り伸び率（％））／（製造から３０日間経過後の結晶化度（％）－製造から１日間経過後の結晶化度（％））｝で示される、シート製造から１日間経過後と３０日間経過後の結晶化度の変化に対する引張り伸び率の変化率が２０以下であり、且つ、シート製造から６０日間経過後の引張り伸び率が１００（％）以上である生分解性樹脂シート。
