<p>PROBLEM TO BE SOLVED: To provide a film having excellent flexibility, moisture permeability, water resistance and disintegration.SOLUTION: A film contains a biodegradable resin and a filler and meets conditions 1 to 3. Condition 1: the void ratio (W) is 30-70%, where the void ratio (W) represents the void ratio measured from the cross section when the film is cut in parallel with the longitudinal direction. Condition 2: the void ratio (W) is 15-40%, where the void ratio (W) represents the void ratio measured from the cross section when the film is cut in parallel with the width direction. Condition 3: the relationship W/Wof Wand Wis 1.3-3.0.</p> |
