Manufacturing and processing Technologies


  • USC Nylon (Pat. 4673598)

    Ultimate Silicone Compounded Combination of ultra-high molecular weight microsilicone and high strength nylon for quantum improvement in abrasion resistance. Better surface smoothness and slickness too.

  • High Molecular Weight Nylon

    Newly developed nylon with even higher molecular weight than our conventional ultra-strength nylon. High levels of straight and knot strength. High performance nylon line that's exceptionally durable, very manageable, with low memory.

  • UV-Resistant process

    Maximum protection against UV damage for vulnerable nylon lines.

Processing technologies

  • Plasma Rise

    Through the joint development with Plasma Concept Tokyo, the world's first realization of continuous atmospheric pressure plasma treatment of fibrous materials, which has been regarded as difficult, has been realized.
    This makes it possible to apply plasma treatment to fishing lines, and to provide various performances. It is an innovative technology with unlimited possibilities that can meet the stoic requirements of anglers.

  • Plasma Ion Technology

    Jointly developed by Sunline and Plasma Concept Tokyo (a Tokyo Institute of Technology venture).Technology to modify the line surface at will to produce the perfect fishing line for any target or situation.

  • Different Part Processing

    A process that partially changes the quality and condition while utilizing the characteristics of the material.

  • Low Stretch processing

    High-performance processing designed to suppress initial elongation and achieve high elongation at break of 3%. Considering the balance of strength, elongation, and impact resistance, this high-sensitivity line clearly conveys the bottom and fish on even in deeper places.

  • Smooth Surface processing

    Special processing technology that finishes the surface of the PE line more smoothly. The surface is smooth and the fiber fuzz is suppressed, and it is finished in a structure close to a perfect circle.

  • Super Dynamic Processing

    Uncompromising design with a focus on tenacity, the index of strength and stretch. This new manufacturing technique imparts the line with the energy to endure to the limit. An exquisite balance of strength and stretch to deliver the toughness needed in real life angling situations.

  • Vivid Dyeing process

    Sunline's unique dyeing technology – vividness, visibility, and softness in one.

  • Quartet Resin Processing

    The next evolution in resin processing: Quad layer resin processing "Quartet Resin Processing" is the next step in the evolution of our proven Triple Resin Processing Technology. A wide variety of resin processes can deliver the ultimate in line quality.

  • Triple Resin Processing

    Retains its strength and suppleness even when knotted "Triple Resin Processing" is a unique process that fills in the spaces between the molecules with resin. As a result, the line is moisture proof, very slick, and resistant to shock and wear.

  • Stretch Memory Processing (special process for high shape recovery)

    Exclusive two-step process that strictly controls line stretch. While retaining enough stretch for tenacity, the process gives the line a high shape recovery for quickly returning to its original length.

  • Multifunctional Resin Processing

    A combination of multifunctional patterns, this processing method adds concept-appropriate function and enhances actual performance.

  • Double Resin Processing

    Enhanced performance with double layer processing In "Double Resin Processing," a double coat of various high-performance resins results in a highly competent line.

  • Single Resin Processing

    Advanced performance and reliability A single coat of multi-purpose resin to enhance the quality of the original line.

  • ARS Processing

    Imparts both abrasion resistance and slickness. Especially effective in achieving amazingly high abrasion resistance.

  • Special Straight Processing

    Processing that sticks to ease of handling and finishes cut-form products straight.

  • Deep Resin Technology

    New and special manufacturing technology from Sunline, which input sound resin to inner part of the line.


  • Parallel spooling

    A spooling system which minimizes curling and surface indentation. Feel the difference as the line comes off the spool nice and straight and very smooth.

  • Non-stress spooling

    Tension-free spooling maximizes the qualities of the line. Because no stress is placed on the line as it is spooled, the line comes off ready to deliver superior stretch performance.
