A water retaining and dissipating bedding for a utility line consists of an elongate trench formed in the earth. One or more subsequent game outcomes can be generated including the retained symbols. The highly oriented polyolefin fiber according to the invention has improved properties in applications such as, in particular, anti-ballistic shaped articles since the fiber contains 0. An important weight reduction of the structure is thus obtained, which allows different applications in the aeolian generation field. The application also describes how such a film may be manufactured.
