Double Sided Filament Tape(PET Film Liner)

Product Description:

D980 is a reinforced double sided filament tape designed for industrial bonding applications where ordinary double sided tape may stretch, split, or become difficult to handle during application. It combines bi-directional fiberglass filaments, a pressure-sensitive acrylic adhesive, and a PET film release liner to provide stable dimensional control and reliable bonding performance.

The PET film liner is a key feature of this tape. Compared with paper release liners, PET film offers better tear resistance, smoother release, and more stable handling during die-cutting, lamination, and manual or semi-automatic application. This makes D980 suitable for production environments where liner breakage, inaccurate placement, or stretching during application can cause waste or rework.

The acrylic adhesive provides reliable adhesion to foam rubber, wood, metal, ABS, PVC, PC, painted surfaces, and other common industrial substrates. For low surface energy materials such as PE, PP, silicone rubber, or textured surfaces, bonding should be tested before mass production.

Typical Applications:

· Foam rubber sealing strip bonding

· Automotive interior foam, trim, and light component attachment

· Furniture backing, upholstery support, and panel bonding

· Foam lamination and cushioning material assembly

· Plastic, metal, and wood component fixing

· Die-cut parts requiring stable liner release

· Industrial assembly where low stretch and split resistance are required

Why Choose PET Film Liner:

The PET release liner helps improve processing stability, especially when the tape is used for die-cutting, laminating, or precise manual placement. It reduces the risk of liner tearing during removal and provides cleaner, more controlled release than many paper liner options.

This is especially useful when bonding foam strips, pre-cut pads, interior parts, or components that need accurate positioning before final pressure is applied.

Key Features:

· Bi-directional fiberglass reinforcement for high tensile strength

· Low stretch construction for stable placement

· PET film release liner for tear-resistant handling

· Acrylic pressure-sensitive adhesive for industrial bonding

· Good split resistance during application

· Suitable for foam, plastic, metal, wood, and painted surfaces

· Works well for die-cutting, lamination, and assembly processes

· Available in roll or custom slit widths upon request

Technical Datasheet

Application Notes:

For best bonding results, apply the tape to clean, dry, and oil-free surfaces. Press firmly after application to ensure full adhesive contact with the substrate. Bond strength may continue to build after the tape is applied.

For foam rubber, painted parts, plastics, or textured surfaces, we recommend testing the tape under actual production conditions before bulk use. Surface energy, coating type, pressure, temperature, and dwell time can all affect final bonding performance.

This tape is intended for bonding, fixing, lamination, and assembly support. It should not be used as a replacement for structural fasteners or mechanical fixing in load-bearing applications unless validated by testing.

Testing and Quality Control:

D980 can be supplied with technical data based on standard tape testing items such as thickness, peel adhesion, tensile strength, and elongation. Test methods and inspection requirements can be confirmed according to customer application needs.

For projects requiring specific test standards, temperature resistance, liner release force, or long-term aging performance, please contact us before order confirmation.

For other reinforced tape options, review our filament strapping tape range.

Storage and Handling:

Store the tape in a clean, dry environment away from direct sunlight, high humidity, and heat sources. Recommended storage temperature is 15°C to 30°C. Keep the roll in its original packaging before use.

For best performance, use the tape within the recommended shelf life and allow it to reach room temperature before application if stored in a cold environment.

FAQ:

Q1: What is the main advantage of PET film liner?
A: PET film liner provides better tear resistance and smoother release than many paper liners, making the tape easier to handle during die-cutting, lamination, and precise placement.

Q2: Is this tape suitable for foam rubber bonding?
A: Yes. D980 is suitable for foam rubber sealing strips, foam lamination, and cushioning material assembly. Testing is recommended for textured or low surface energy foam materials.

Q3: Can it be used for automotive interior applications?
A: It can be used for light automotive interior bonding, trim fixing, foam attachment, and similar assembly tasks. Final suitability should be verified under actual temperature, surface, and vibration conditions.

Q4: Is the adhesive acrylic or synthetic rubber?
A: D980 uses a pressure-sensitive acrylic adhesive. Acrylic adhesive is commonly selected for stable industrial bonding and better aging resistance than many rubber-based systems.

Q5: Can this tape bond to plastic?
A: It can bond to many plastics such as ABS, PVC, PC, and painted plastic surfaces. PE, PP, silicone, and other low surface energy materials require application testing.

Q6: Can you supply custom roll widths or die-cut parts?
A: Yes. Custom widths, roll lengths, and die-cut shapes can be discussed based on the application, liner requirements, and order quantity.
