Abstract
The present invention relates to a prestretched polyethylene film having a longitudinal stretch ratio of from about 1:2 to about 1:4 and having a longitudinal elongation capability of at least 170%, said elongation capability comprising an elastic component. The invention also relates to a method for producing said film and to a method of wrapping compressed bulk material such as a round bale using said film, the method comprising further stretching the prestretched film and applying the film around the compressed bulk material in direct contact therewith. The film according to the invention may be used as a net replacement film and allows increasing the efficiency and the economics in the baling process by allowing faster baling, use of a lesser amount of wrapping film and/or improved protection of the product.
