High-performance pressure-sensitive adhesive is applied on both sides of double-sided PET tape, a unique tape composed of polyester film (PET) as the basis material. The PET base material is renowned for its superior temperature resistance, dimensional stability, and mechanical strength. This tape is indispensable for both everyday use and industrial production when paired with a correctly designed adhesive system.
Important Features of Double-Sided PET Tape
Superior Adhesion: Acrylic or rubber-based adhesives are used in premium double-sided PET tape to provide dependable, long-lasting adhesion for a range of surface materials.
Superior Temperature Resistance: While special models may tolerate brief high temperatures as high as 200°C, standard goods can tolerate temperatures between -20°C and 120°C.
Outstanding Chemical Resistance: It is resistant to most chemicals, oils, and solvents.
Ultra-Thin Design: With a thickness of between 0.03 and 0.25 mm, concealed bonding is possible without compromising the product's look.
Electrical Insulation Performance: The PET base material is appropriate for electrical and electronic applications due to its high dielectric strength.
Principal Uses of Double-Sided PET Tape in the Electronics Sector
PET tape with two sides is widely used in contemporary electronics:
Fixing mobile phone and tablet components (such as screens, batteries, and camera modules)
Component shielding and insulation on PCB boards
Touch screen assembly
Flexible circuit board (FPC) fixing
Automotive Manufacturing
Interior trim installation (decorative strips, logos, panels)
Wire harness fixing
Thermal and sound insulation material bonding
Sensor and electronic module installation
Industrial Manufacturing and Assembly
Nameplate, label, and marking application
Bonding of plastics, metals, and composite materials
Temporary or permanent fixing of precision components
Special applications in packaging and sealing
How to Choose the Right Double-Sided PET Tape?
1. Determine the Base Material Thickness
Depending on the application's strength needs and available area, select the proper PET base material thickness. Precision electronics can employ ultra-thin kinds (0.03-0.05mm), most industrial applications can use ordinary types (0.08-0.13mm), and uneven surfaces or applications requiring more cushioning can use thicker types (0.15-0.25mm).
2. Matching Adhesive Type
Acrylic adhesive system: Provides excellent overall performance, good weather resistance, and strong long-term durability.
Rubber-based adhesive system: High initial tack, suitable for irregular surfaces, but relatively poor temperature resistance and aging resistance.
3. Considering the Application Environment
Indoor or outdoor use
Extreme temperature conditions
Potential for chemical contact
UV exposure
4. Surface Compatibility
Different surfaces have varying requirements for adhesives:
Low surface energy plastics (such as PP, PE) require specialized adhesive formulations.
Rough or porous surfaces require a thicker adhesive layer or specific adhesives.
High surface energy materials (such as glass and metal) have better compatibility.
Application Advice for Double-Sided PET Tape
Surface pretreatment: Make sure the bonding surface is dry, clean, and devoid of dust and oil.
Apply uniform pressure, usually between 10 and 15 psi, for 10 to 30 seconds.
Curing time: To get the highest bonding strength, the majority of acrylic adhesives need to cure for 24 to 72 hours.
Temperature influence: Apply more pressure or prolong the pressing duration when the temperature is low.
Storage conditions: 15–25°C and 40–60% humidity in the original packing.
Expert Guidance and Safety Measures
It is advised to thoroughly discuss application requirements with a qualified manufacturer when choosing double-sided PET tape, and to test samples if needed. In addition to ensuring bonding efficacy, proper tape selection maximizes production efficiency, lowers costs, and increases the final product's dependability.
To assess the tape's performance in specific application scenarios, we, as professional tape makers, recommend that consumers conduct small-scale testing before making bulk purchases. To ensure the material performs optimally when in use, monitor the tape's shelf life and storage conditions.
