Double Sided Filament Tape(PET Film Liner)

Product Description

A high-strength, bi-directional double-sided filament tape reinforced with fiberglass filaments and equipped with a PET release film liner for superior dimensional stability during application. Both sides are coated with a pressure-sensitive adhesive system designed to deliver reliable shear strength and controlled bond build-up.

Compared with paper liner versions, the PET film liner provides improved tear resistance, consistent release force, and smoother handling during automated or high-speed lamination processes. This construction is particularly suitable for industrial foam bonding, interior automotive assembly, and applications requiring precise placement and liner integrity.

Datasheet

Features

• PET film release liner — high tear resistance and stable release for manual or automated application

• Fiberglass filament reinforcement — enhanced tensile strength and shear resistance

• Bi-directional reinforcement structure — reduces stretch and creep under load

• Pressure-sensitive adhesive system — balanced initial tack and holding power

• Cleaner liner removal — ideal for precision assembly and production-line use

Applications

• Bonding foam rubber sealing strips in doors, windows, and enclosures

• Automotive interior assembly and vibration-exposed components

• Foam lamination, cushioning fixation, and trim installation

• Furniture backing and industrial upholstery bonding

• Industrial assembly where liner integrity and placement accuracy are critical

Testing & Compliance

Typical performance values are based on laboratory testing conducted under controlled conditions according to relevant ASTM / GB-T methods. Results are provided for reference only. End users should perform application-specific testing prior to production use. Certificates of Analysis (COA) and supporting test reports are available upon request.

Storage & Handling

Store at 4–26°C (39–79°F) and 40–50% RH. Keep away from direct sunlight, solvents, and excessive humidity. Allow tape and substrates to equilibrate to room temperature before application. Apply firm, even pressure to achieve optimal adhesive contact.

FAQs

Q1: What is the advantage of a PET liner compared to glassine paper liner?

A: PET film liners offer higher tear resistance, dimensional stability, and consistent release force. They are preferred for automated application, precision placement, and environments where paper liners may deform or tear.

Q2: What substrates does this double-sided filament tape bond to?

A: It bonds well to foam rubber, painted metal, plastics (ABS, PVC, PC), wood panels, and coated surfaces. Proper surface cleaning is essential for optimal adhesion.

Q3: What temperature range can this tape withstand?

A: Typical operating range is -5°C to +70°C, depending on load and dwell time. It is suitable for appliance, automotive interior, and general industrial assembly, but not for high-temperature curing ovens.

Q4: Is this tape intended for structural bonding?

A: No. This tape is designed for non-structural industrial bonding, reinforcement, and fixation. It is not a replacement for mechanical fasteners in load-bearing structural joints.

Q5: What roll sizes and customization options are available?

A: Standard widths range from 12mm to 100mm, with common lengths of 50m or 100m. Custom sizes, core options, and packaging formats are available for OEM customers. Samples can be provided for evaluation.
