What is filament tape used for and How strong is filament tape?

Filament tape is an industrial tape made of fiberglass material, which has the characteristics of high temperature resistance, high tensile strength, and chemical corrosion resistance.

Fiber tape is made by embedding high-strength glass fiber or polyester fiber into a pressure-sensitive adhesive layer, which combines high tensile strength and strong adhesion. Common uses include:

Heavy duty packaging

Reinforce cardboard boxes (especially for fragile or overweight items) to replace traditional packing straps.

Secure palletized goods to prevent looseness during transportation.

Industry and Architecture

Bind pipes, cable bundles, or metal components.

Temporary fixing of building materials (such as insulation layer, waterproofing membrane).

Home and Maintenance

Repair tool handles, sports equipment, or furniture.

Emergency fixed broken items (such as plastic parts, wooden products).

Special Scene

Good temperature resistance (some models can withstand -30 ° C to 80 ° C), suitable for environments with temperature differences.

Tensile strength

Typical range: The tensile strength of fiber tape is typically between 200-600 pounds per inch (lbs/inch), depending on the brand and model.

Example: Jerrytape Filament Tape  is 500 lbs/inch, while some economical products may have a tensile strength of 200-300 lbs/inch.

Unit conversion: 500 lbs/inch ≈ 87.5 N/mm (Newton/millimeter).

Bundled weight estimation

Theoretical load-bearing capacity=tensile strength (lbs/inch) x tape width (inch) x safety factor

Safety factor: It is recommended to take 30% -50% (depending on the adhesive surface, binding method, and environmental factors).

Example calculation:

Tape parameters: Tensile strength 500 lbs/inch, width 2 inches.

Theoretical limit: 500 × 2=1000 lbs (approximately 454 kg).

Safe load: Calculated at 50% → 500 lbs (approximately 227 kg)

matters needing attention:

The actual load-bearing capacity is significantly affected by the performance of the adhesive, surface cleanliness, and winding method (such as whether it is cross tied).

Extreme temperatures or humid environments may reduce viscosity, so it is necessary to choose the corresponding model (such as low temperature resistant or high viscosity).

Check the tensile strength and width indicated on the product label, and prioritize selecting well-known brands such as  Jerrytape

Choose waterproof type for humid environments and cold resistant adhesive type for low-temperature environments.

When bundling heavy objects, use "multiple winding+cross fixation" to enhance stability.
