Patent number: 8435622Abstract: 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%.Type: GrantFiled: January 13, 2006Date of Patent: May 7, 2013Assignee: Megaplast S.A.

Publication number: 20090047468Abstract: A packaging film comprising a main film made of a stretchable polymer film material and having a multiplicity of holes on the main film includes is four conditions. A first condition means that a ratio of aeration percentage over final weight is greater than or equal to 14 meters per gram. The aeration percentage is calculated for a predetermined length of the packaging film as the total area covered by the holes over the total area of the packaging film including the area of the holes, when the packaging film is stretched to an elongation equal to the elongation at the Natural Draw Ratio point (NDR point). The final weight is the weight of the packaging film per film meter measured in grams per meter, when the packaging film is stretched at an elongation equal to the elongation at the NDR point.Type: ApplicationFiled: January 13, 2006Publication date: February 19, 2009Applicant: Megaplast S.A.
