Abstract

The invention relates to a tape, comprising at least one layer comprising a. endless fiber in an total amount of at least 40 volume % as compared to the total volume of the layer and b. a thermoplastic matrix comprising one or more polyamides containing one or more aliphatic monomeric units, c. and optionally heat stabilizer, flame retardant, colorant, lubricant, mold release agent, UV stabilizer, impact modifier, laser absorbing additive as well as combinations thereof; wherein the one or more polyamides have a CH2-ratio of at least 5.5 and less than 10, calculated by—identifying the number of different aliphatic monomeric units in the one or more polyamides; —determining the number of CH2 groups per aliphatic monomeric unit for each of these different aliphatic monomeric units; —calculating the sum of the so determined numbers of CH2 groups; —dividing said sum by the number of different aliphatic monomeric units in the one or more polyamides; taking into account only the aliphatic monomeric units present in the one or more polyamides in an amount of at least 10 wt % with respect to the total weight of the one or more polyamides. The invention also relates to a vessel prepared by employing these tapes.
