Braided jackets with low thickness

A method for producing a cord having a core-sheath structure, the method comprising:

• shaping at least one filament bundle comprising a plurality of filaments to form at least one shaped strand of filaments, wherein the shaping comprises squeezing the at least one filament bundle between two surfaces;
• and
• braiding a plurality of strands, including the at least one shaped strand of filaments, over a core to form the core-sheath structure comprising a braided sheath of the strands surrounding the core,
• wherein:
• the shaped strand of filaments is an untwisted strand having a twist level of less than 1 turn per meter;
• a cross-sectional aspect ratio of the shaped strand of filaments is at least 3:1, as measured in the braided sheath;
• a thickness of at least a portion of the braided sheath ranges from about 10 to about 200 μm;
• and
• the braided sheath comprises a synthetic fiber having a tensile strength of greater than 12 cN/dtex.
