The choice of cord depends heavily on the application. For Macramé and Crafting, a 3-strand or 4-strand twisted cord provides better structure, while single-strand cord offers a softer, brushed fringe effect. For Industrial or Packaging use, focus on tensile strength (breaking load) and linear density (grams per meter). If the cord is for Food Packaging (e.g., meat trussing), it must be unbleached, food-safe, and FDA-compliant. Always confirm the diameter consistency (e.g., ±0.5mm tolerance) to avoid issues in automated machinery or aesthetic defects in handicrafts.
