Abstract

基材層だけでなくヒートシール層も生分解性樹脂により形成することにより、自然環境において優れた生分解性を有し、且つ、ヒートシール部のヒートシール強度と、基材層とヒートシール層間のラミネート強度にも優れた包装用フィルム及び、該フィルムを用いて作製した袋体を提供する。ポリ乳酸を含む生分解性樹脂からなる基材層（Ｉ）の少なくとも一面側に、脂肪族ポリエステルを含む生分解性樹脂からなるヒートシール層（ＩＩ）が積層されてなる生分解性フィルムにおいて、上記基材層（Ｉ）の融点Ｔｍ（Ａ）と上記ヒートシール層（ＩＩ）の融点Ｔｍ（Ｂ）との差（Ｔｍ（Ａ）－Ｔｍ（Ｂ））が、５５°C以上であることを特徴とする生分解性フィルム。
