  • Our take on the Self-Adhesive Insulation Fish Paper – 70mm x 5m Roll

    This is a 70mm-wide, 5-meter roll of fish paper with a peel-and-stick adhesive backing, used to insulate and protect lithium-ion battery packs and electronic assemblies. Fish paper is a dense, fibrous electrical-grade material known for high dielectric strength and heat resistance, and the adhesive backing removes the need for separate glue on flat and gently curved surfaces. It suits battery builders working with 18650, 21700 and LiFePO4 cells, plus DIY electronics and repair work. Against plain fish paper sheets, the roll format and adhesive save time, but the fixed 70mm width limits it where narrower strips or wider coverage are needed.

    Pros
    • Peel-and-stick backing applies fast without glue or tools
    • 70mm width covers common battery pack and holder spans
    • 5m length gives plenty of material for multiple packs
    • Flexible paper conforms to contours and tight spaces
    • Rated for dielectric strength, heat resistance and flame resistance
    Cons
    • Fixed 70mm width is too wide for narrow gaps and too narrow for large panels
    • Adhesive quality and long-term hold are not specified
    • Paper can tear or crease if handled roughly during wrapping
    • No thickness or dielectric strength figures given to compare grades

    About the Self-Adhesive Insulation Fish Paper – 70mm x 5m Roll

    This is a self-adhesive insulation fish paper roll for electrical insulation in lithium-ion battery packs and electronic assemblies. The industrial-grade paper has dielectric strength, thermal stability, and flame resistance.

    The roll is 70mm wide and 5 meters (16.4 feet) long. The adhesive backing peels and sticks in place, so no extra glue or tools are needed. The material is flexible and conforms to contours, corners, and tight spaces.

    It is used for protecting 18650, 21700, and LiFePO4 battery packs.

    Questions and answers

    What is fish paper used for?
    It is an electrical-grade insulating paper used to separate and protect battery cells, circuit boards and other components. It resists heat and voltage, which makes it common in lithium-ion pack assembly.
    Will it stick to battery cells and holders?
    The roll has a self-adhesive backing, so it presses onto clean, dry surfaces without extra glue. Smooth flat areas hold best; dusty or oily surfaces should be cleaned first.
    Does 70mm width fit 18650 and 21700 packs?
    70mm spans several 18650 cells side by side and covers 21700 cell holders well. For narrow strips between cells you will need to cut it down.
    How much does one roll cover?
    The roll is 70mm wide and 5 meters long, about 16.4 feet. That is enough for several small battery packs or one large pack, depending on how you cut it.
    Is it flame resistant?
    The material is described as flame resistant and heat resistant, which is why it is used inside battery packs. It is an insulator, not a substitute for a proper fuse or protection circuit.
