What Is The Typical Construction Of Tape ?

Typical construction for Pressure Sensitive Adhesive (PSA) Tapes include the following:

  • Single Coated (PSA) Tapes: An adhesive coated on one side of material (facestock). The Adhesive is protected by a silicone coated release liner
    • Typical uses of single coated tapes include label stock, wound care products, duct and insulation tapes.
    •  The construction of single coated tapes include:
      1. A Facestock
      2. An Adhesive
      3. A Silicone
      4. The Release Liner
  • Double Coated PSA Tapes or Double Sided (PSA) Tapes: A carrier is coated on both sides with pressure sensitive adhesive (PSA). The carrier can be a wide variety of materials including plastic films, tissue, non-covens, cloth, etc.  The adhesive is protected by the release liner coated with silicone on both sides.
    • Typical benefits of using double coated tapes include:
      • Carrier offers ease of handling and slitting.
      • Can serve to reduce over laminating on porous materials.
      • Carrier offers the ability to use different adhesives on each side (differential adhesive), enhancing application flexibility.
    •  The construction of double coated tapes include:
      1. An Adhesive
      2. The Carrier
      3. An Adhesive
      4. A Silicone
      5. The Release Liner
      6. A Silicone
  • Transfer (PSA) Tapes: An unsupported adhesive film coated on a release liner which is silicone coated on both sides. Transfer tapes offer superior conformability with irregular surfaces (e.g. textured, curved).
    • Typical uses of transfer tape include nameplate application, bonding, foam bonding graphic displays, splicing etc.
    • The construction of transfer tapes include (version 1):
      1. The Adhesive
      2. A Silicone
      3. The Release Liner
      4. A Silicone
    • The construction of transfer tapes include (version 2):
      1. The Adhesive
      2. The Silicone Coated Release Liner
  • Double Liner Transfer (PSA) Tapes: An unsupported adhesive film protected by a release liner on both sides. Each liner is silicone coated on the side facing the adhesive. Generally used where the adhesive needs to be die cut prior to hand installation of adhesive to a finished part.
    • Typical uses of double liner transfer tapes are commonly used in membrane switch industry and decorative overlays.
    • The construction of double liner transfer tapes include:
      1. The Release Liner
      2. A Silicone
      3. An Adhesive
      4. A Silicone
      5. The Release Liner
  • Self Wound (PSA) Tapes: A carrier which is coated on one side with pressure sensitive adhesive (PSA) and on the other with a silicone release coating. Note: there is no release liner.
    • Typical uses for self wound tapes include packaging tapes, electrical tapes, masking tapes, and duct tapes.
    • The construction of self wound tapes include:
      1. An Adhesive
      2. The Facestock
      3. A Silicone
