  • Patent number: 8435622
    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%.

  • Patent number: 8053055
    Abstract: A stretch film comprising a base film made of a stretchable plastic film material, a multiplicity of holes in the base film arranged in several columns along a main direction, at least one reinforcement strip made of a stretchable plastic film material. The reinforcement strip is arranged and fixed on the base film in an area between two adjacent columns of holes. The thickness of the base film is greater than or equal to the thickness of the reinforcement strip and the width (w) of the reinforcement strip is as great as possible, but is such that the reinforcement strip does not contact or overlap the holes in the adjacent columns of holes. The reinforcement strip may be fixed to the base film so as to be inseparable and indistinguishable from the base film.

  • Patent number: 7682683
    Abstract: A stretch film with a base (1) consisting of a film material and with a multitude of holes (2) that are formed in the base (1) in several rows (3) of holes extending, in essence, in parallel to each other and in a main direction (X) comprises at least one layer of strips (4) consisting of a film material and extending in the main direction (X), said layer being arranged on the base (1) between the rows (3) of holes. Owing to the applied strips (4), a high stretchability of the stretch film can be achieved.

  • Publication number: 20090047468
    Abstract: 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.
