The invention relates to a tubular biaxially extended, optionally multilayered plastic gut containing at least one layer of polyamide and optionally, polyolefins. The invention is characterised in that said layer contains 0.1 - 4 wt.- % of dispersed nano particles whose smallest particles form a rigid unit in the dispersion of nano particles, in respect to the weighted average of all particles, having an extension of no more than 100 nm in at least one variably selectable direction. |
