Abstract:
A packaging film with a main film made of a stretchable polymer film material and having a multiplicity of holes. A first condition of the main film including that a ratio of aeration percentage over final weight is greater than or equal to 14 meters per gram. A second condition of the main film is that the width of the packaging film is reducible by less than 15% between a condition before any stretching of the packaging film and a condition when the packaging film is stretched at an elongation equal to the elongation at the NDR point. A third condition of the main film is that a ratio of an absolute value of the difference of a holding force of the packaging film minus a predetermined target holding force divided by the target holding force is less than or equal to 5%.
