Aluminum Foil Tape

Aluminum foil tape is a functional industrial tape made from high-purity aluminum foil (≥99.95%) as a backing material and coated with a pressure-sensitive adhesive.

Production Process Flow

From raw materials to finished product, every step is rigorously controlled to ensure consistent and reliable performance.

A high-performance pressure-sensitive adhesive is uniformly applied to a large jumbo roll of aluminum foil backing using a precision coating machine.

The coated foil then passes through a long drying oven. The heat evaporates the solvent from the adhesive, leaving a smooth, stable, and tacky layer.

For tapes that require a release liner, a silicone-coated paper or film is laminated onto the adhesive surface at this stage.

The large jumbo roll is then precisely cut into smaller rolls of specific widths and lengths according to customer requirements using a slitting machine.

Finally, the finished rolls are individually wrapped, labeled, and packed into cartons for shipment.

Technology Showdown: Aluminum Foil Tape vs. Duct Tape

While both are staple utility tapes, their core materials lead to vastly different performance characteristics. The choice between them is critical for applications involving temperature, moisture, and long-term durability.

Aluminum Foil Tape

  • Excellent Thermal Resistance: Performs reliably in extreme cold and high heat, making it ideal for HVAC, ductwork, and thermal insulation.

  • Weather & UV Resistant: The metallic backing is impervious to UV degradation and moisture, ensuring long-term outdoor durability.
  • Chemical Resistant: Resists exposure to many common chemicals, oils, and greases.

  • Conductive Properties: Can be used for thermal conductivity or electrical shielding applications.

  • Low Tear Resistance: The thin foil backing can be punctured or torn more easily than fabric-reinforced tapes.

Duct Tape

  • High Tensile Strength: The fabric mesh reinforcement provides excellent strength and resistance to tearing and abrasion.

  • Flexible & Conformable: Easily conforms to irregular shapes and surfaces for general repairs and bundling.

  • Strong Initial Adhesion: The aggressive rubber-based adhesive sticks well to a wide variety of surfaces.

  • Poor Temperature Resistance: The adhesive can fail in high heat, and the backing can become brittle in extreme cold.
  • Not UV Resistant: The polyethylene coating degrades quickly under sun exposure, leading to failure in outdoor applications.
  • Leaves Heavy Residue: The adhesive often breaks down over time, leaving a difficult-to-clean sticky residue.

Functions, Uses, and Applications

Aluminum foil tape is a versatile material used in a wide range of demanding environments. Its core function is to provide a durable, reflective, and conductive barrier for sealing, shielding, and repairing.

Thermal Shielding & Sealing

Reflects heat and light. Seals joints and seams in HVAC ductwork to prevent air leaks and improve energy efficiency.

Moisture & Vapor Barrier

Creates a waterproof and vapor-proof seal on insulation materials, protecting them from moisture and environmental damage.

Electrical & EMI Shielding

Provides a conductive surface for grounding, draining static charge, and shielding sensitive electronic components from electromagnetic interference (EMI).

Primary Application Fields

Our product is widely used for sealing, shielding, and repair in numerous industrial and commercial sectors:

  • HVAC & Refrigeration (duct sealing, insulation wrapping)
