With an adhesive that is evenly distributed on both sides, double-sided PET tape is created from PET film. Due to its excellent performance and broad application, double-sided PET tape has become a necessity in the electronics, automotive, and packaging industries.
Leveraging its combined advantages of high-strength bonding and the stability of the PET substrate, double-sided PET tape has achieved deep penetration in multiple industries:
Electronics and 3C Industries
It is a core component in devices such as smartphones and laptops.
Screen Module Bonding: Using 0.05 mm ultra-thin, transparent double-sided PET tape, seamlessly bonds the touchscreen and LCD module, ensuring no bubbles or optical distortion.
Battery Fixing: In new energy battery packs, a high-temperature-resistant tape is used to secure the battery cell to the casing, withstanding temperature fluctuations (-20°C to 60°C) during charging and discharging.
FPC (Flexible Printed Circuit) Reinforcement: Using high-tensile-strength tape to enhance the mechanical strength of the FPC's bends, extending its service life by more than three times. Automotive Manufacturing and Rail Transit
Replacing traditional mechanical fasteners such as screws and clips:
Interior Assembly: Use acrylic tape to bond instrument panels and door panel trims, eliminating vibration-induced noise while reducing vehicle weight by 5%-8%;
Wiring Harness Fixing: Use oil- and heat-resistant double-sided PET tape to secure wiring harnesses within the engine compartment, resistant to corrosion from engine oil and coolant.
Window Sealing: Apply tape to the edges of high-speed rail windows, achieving both bonding and waterproofing performance, meeting the IP67 protection rating.
Packaging and Printing Industry
Solving the need for high-precision, high-stability bonding:
Gift Box Binding: Use low-odor tape to bond gift box linings and exteriors, preventing glue spillage and affecting aesthetics;
Label Lamination: Used on the back of anti-counterfeiting labels on food packaging, ensuring they remain attached even in refrigerated environments (0°C-5°C);
Printed Product Mounting: Replaces traditional starch adhesive, enabling rapid bonding between paper and PET film, increasing production efficiency by 40%. New Energy and Photovoltaic Fields
Adapting to the reliability requirements of harsh environments:
Photovoltaic Modules: Weather-resistant tape applied between the solar panel frame and the glass, resisting UV rays and rain damage, ensuring a 25-year service life;
Energy Storage Devices: Used for sealing and securing energy storage battery casings, withstanding extreme temperature cycles from -40°C to 85°C.
Double-Sided PET Tape Industry Development Trends
High-Performance
Ultra-High-Temperature-Resistant Types: Developing silicone-based tapes capable of withstanding temperatures of 300°C, suitable for extreme applications such as new energy vehicle motors and aerospace equipment;
Ultra-Thinness: Developing ultra-thin tapes below 0.02 mm to meet the "seamless bonding" requirements of precision tools like foldable phones. Sustainability and Environmental Protection
Bio-based PET substrate: Using plant-derived PET raw materials lessens dependence on petroleum resources, and the finished product is partially degradable in the environment.
Removing traditional solvent-based adhesives from the production process, reducing VOC emissions by over 90%, and adhering to environmental regulations like EU REACH and US EPA.
The development of double-sided PET tape has always been closely tied to modern upgrades in downstream industries. With the continued growth of 5G, new power, and high-end production, performance requirements may further boost, driving the industry towards breakthroughs in "more accurate, more environmentally friendly, and smarter" technologies. When choosing, you need to consider parameters such as heat, humidity, and the pressure setting of the specific situation to increase its value.
