This invention relates to a prestretched film (2). This invention relates in particular to a prestretched blown extrusion film (2) which is used in baling applications for packaging of, for example, silage, maize, sugar beet pulp, malt, straw, household refuse and other bales. The prestretched film is obtained by stretching a film in the longitudinal direction to at least 60% of its elongation percentage at break, so that in the longitudinal direction said film now only has a maximum elongation capability of 180% left, or has a 2% Secant Modulus of at least 55N/15mm or has a 10% secant Modulus of at least 35N/15mm. |
