Overview
ALS Tape supplies foil adhesive tapes for sealing, shielding, and thermal management across HVAC, electronics, automotive, aerospace, and construction. Three core constructions cover the main application directions: aluminum foil tape for heat reflection, thermal insulation, and duct sealing; copper foil tape (conductive and non-conductive variants) for EMI/RFI shielding, electrical grounding, and sensitive component protection; and reinforced and composite foil tape laminated with PET film or glass fiber for heavy-duty applications requiring extra tensile strength, tear resistance, and puncture protection. Adhesive systems include acrylic, silicone, and synthetic rubber, available in custom slit widths, variable adhesive thicknesses, and tailored release liners for production compatibility. Foil tapes are slit to width or die-cut into grounding tabs, shielding frames, strips and kiss-cut parts on liner.

FAQ
Which foil tape is best for EMI shielding?
Copper foil tape with a conductive adhesive, such as 3M 1181, has the lowest resistance and can be soldered, so it is the usual choice for grounding tabs and seams. Aluminum foil tape with conductive adhesive, such as 3M 1170, is lighter and lower in cost. If the tape must connect through its adhesive face, choose a conductive adhesive.
What is the difference between conductive and non-conductive adhesive foil tape?
A conductive adhesive contains particles that carry current from the foil to the surface below, so the tape grounds through its whole bonded area. A non-conductive adhesive insulates the foil from the surface; it suits heat reflection, moisture barriers and shielding where contact is made by soldering or by the foil face.
Which aluminum foil tape handles high temperature?
3M 363, an aluminum foil laminated to glass cloth with silicone adhesive, is rated by 3M for continuous use from −54 to 316 °C. 3M 425 with acrylic adhesive is rated from −54 to 149 °C and carries UL 723 Class L low-flammability classification.
Can foil tape be die-cut into custom shapes?
Yes. Foil tapes are slit to custom widths or die-cut into tabs, frames, strips and shapes, either as loose parts or kiss-cut on a liner for automatic placement. Die-cut parts start from 100 pcs and custom samples take 3–9 days.
Do you supply other foil tape grades?
Yes. The table lists common 3M grades. Other aluminum, copper, tin-plated copper and reinforced foil tapes can be sourced on request; send the grade or the data sheet you are working from and we confirm availability, width and price.
