Stretch film

Stretch film comprising a base consisting of a film material;

• a multitude of holes, said holes being formed in the base in several rows extending in parallel to each other and in a main direction;
• said stretch film further comprising:
• at least two layers of reinforcing strips consisting of a film material and extending in the main direction wherein said at least two layers of strips are attached to the base one above the other between the rows of holes, wherein said at least two layers of strips are only attached to the base and to each other at their major planar faces and wherein respective pairs of adjacent strips are disposed on both sides of a row of holes, said at least two layers of strips being devoid of said holes;
• wherein the width of at least a part of the separation between the respective adjacent pairs of strips extending in transverse direction in relation to the main direction, is dimensioned such that the strips each reach up to the rows of holes adjacent to said strips to define between said respective pairs of adjacent strips a fixed width for said holes extending in the transverse direction, for preventing the development of tears in the film material and for preventing the spreading of such tears;
• wherein the strips are generally even, but at least without wrinkles;
• and
• wherein each hole is surrounded by a bead having a thickness that exceeds a thickness of the base.
