Double-Sided Bonding Films
-- Steady & Reliable Manufacturer --
Technical Overview
Double-sided bonding films are pressure-sensitive adhesive (PSA) products consisting of an adhesive layer coated onto both sides of a thin carrier (typically PET, PVC, or Non-Woven tissue), or an unsupported "transfer tape" film of adhesive only. The carrier provides dimensional stability and thickness control, critical for maintaining bond line integrity.
These products are designed for permanent or semi-permanent attachment, providing high shear strength, peel strength, and resistance to environmental factors like temperature, humidity, and plasticizers. Key technical specifications include the type of adhesive (e.g., modified acrylic, pure acrylic), total thickness (caliper), and the release liner material, which must be selected for reliable dispensing and consistent adhesive transfer.
Why Choose Us
Differentiating Attributes
- High Initial Tack and Ultimate Bond Strength: Modified acrylic and rubber-based adhesives are formulated to provide instant bonding and long-term structural integrity.
- Uniform Stress Distribution: Unlike spot welding or screws, the film distributes load across the entire bonded area, mitigating stress points and preventing material fatigue.
- Clean and Invisible Bond Line: Eliminates the need for visible mechanical fasteners, enhancing the aesthetic appeal and smooth finish of the final product.
- Resistance to Environmental Stress: High-performance acrylics offer reliable adhesion under exposure to temperature extremes, humidity, and common industrial solvents.
- Precision Thickness Control: Film carriers ensure a uniform, thin bond line, crucial for assemblies with strict dimensional tolerances (e.g., displays and thin electronics).
- Simplified Assembly Process: Requires minimal surface preparation and cures instantly (unlike liquid adhesives), significantly speeding up assembly line throughput.
Core Features
Applications
- Electronic Display and Bezel Attachment: Bonding touchscreens, lenses, and decorative trim to device housings, requiring thin bond lines and high shear strength.
- Gasket and Seal Mounting: Permanently attaching pre-cut foam or rubber gaskets to metal or plastic surfaces in appliance and automotive assemblies.
- Nameplate and Emblem Mounting: Permanent attachment of metal or plastic identification plates on machinery, vehicles, or consumer goods.
- Flex Circuit and Cable Fixing: Securing flexible electronic circuits (FPC) and internal ribbon cables within compact electronics.
- Splicing and Core Starting: Providing high-integrity splicing in roll processing of paper, film, and foil.
Technical Specifications
Introduction
Double-sided bonding films are precision-engineered joining solutions, replacing mechanical fasteners like screws, rivets, and liquid glues in many high-speed manufacturing environments. They provide stress distribution across the entire bond line, resulting in cleaner aesthetics and often higher strength-to-weight ratios.

Frequently Asked Questions
Frequently Asked Questions (FAQs)
- Q: What is the benefit of a PET carrier vs. a tissue carrier?
- A: PET film provides superior dimensional stability, tear resistance, and high temperature performance. Tissue carriers are more conformable and generally cheaper, often used for bonding flexible or irregular materials.
- Q: Can these tapes bond dissimilar materials, such as metal to plastic?
- A: Yes, this is a core application. The adhesive can bridge the gap between materials with different surface energies (e.g., LSE plastics to HSE metals), preventing galvanic corrosion that can occur with direct metal-to-metal contact.
- Q: Are transfer tapes stronger than carrier-based double-sided tapes?
- A: Not necessarily. Transfer tapes (adhesive only) are highly conformable and create an invisible bond but offer no dimensional stability. Carrier-based films offer greater shear strength and handling stability during assembly.
- Q: How do I ensure reliable bonding to low surface energy (LSE) plastics?
- A: For LSE materials (like PE or PP), a specialized high-tack acrylic adhesive with a specific formulation must be used. In some cases, light surface preparation (e.g., plasma or primer) may be required before application.
