Output (English): In the present invention there is disclosed a low energy fuse, comprising a plastic tube with a channel, whereby the channel contains a reactive material able upon ignition to sustain a shock wave within the channel, and whereby the tube further comprises at least two layers of plastic materials, a first plastic layer being situated closer to the channel and a second plastic layer being situated outside the first layer, whereby at least the second layer contains a major amount of draw orientable polymer resin. The polymer in the second layer is axially oriented to an orientation degree (as defined) of more than 20 percent and less than 90 percent and that the polymer of the first layer has an axial orientation degree not exceeding 10 percent orientation degree units more than that of the second layer. The tube can be manufactured by the following steps: a) forming, by extrusion of the first layer plastic, the first layer in the form of a tube, b) introducing the reactive material in the tube channel, c) limiting stretching of the first layer to give a low degree of orientation, not exceeding 10 percent (as defined), d) forming, by extrusion of the second layer plastic, the second layer around the first tube, while the first layer has said low degree of orientation, and e) cold-stretching the first and second layers together.
