As the smart card industry continues to raise requirements for card durability, interlayer bonding strength and appearance yield, conventional lamination films often suffer from hot-press delamination, poor flatness, cracking upon bending and pattern distortion. Our company has launched PET adhesive films specially developed for composite smart card processes, offering mainstream thickness options including 0.06mm and 0.08mm, suitable for lamination production of various composite smart cards such as bank cards, RFID cards, transit cards and identity cards.

Core Product Advantages:

1．Accurate multi-thickness options compatible with diverse card structures Standard thickness specifications including 0.06mm and 0.08mm are available. Ideal for frequently used financial cards and access identity cards to meet heavy-duty application scenarios. Strict thickness tolerance control ensures uniform thickness across the entire roll and consistent pressure distribution during hot pressing, greatly reducing the risk of finished card warpage.

2．Strong interlayer adhesion and outstanding lamination stability It forms a firm bond with card core substrates after hot pressing and maintains long-lasting adhesion, resisting peeling and delamination during prolonged use. The optimized adhesive formulation delivers moderate fluidity in hot pressing with minimal adhesive overflow, effectively reducing defects such as blisters and pinholes to improve finished card yield. It ensures stable structure in chip areas without compromising RF read-write performance.

3．Excellent mechanical properties and weather resistance of substrate The PET substrate features high tensile strength, good bending resistance and superior dimensional stability, resisting shrinkage and deformation under high and low temperature conditions. Finished cards offer abrasion resistance, chemical resistance and wide temperature tolerance. They withstand repeated daily bending and friction, resist yellowing during long-term storage and keep graphics and texts on the card surface clear to extend smart card service life.

4．Premium optical performance and great printing compatibility The film has high transparency and low haze. It will not obscure printed patterns and anti-counterfeiting information on card surfaces after lamination. Its highly flat surface supports mainstream card printing processes including offset printing, screen printing and laser marking. It delivers a clean visual effect after lamination and fits the manufacturing of high-grade ID cards and anti-counterfeit smart cards.

5．Good processing compatibility and stable, controllable mass production Compatible with standard smart card laminators in the industry with no production line modification required. The roll material has excellent cutting performance and can be slit into custom widths. Bulk supply maintains consistent quality. Low batch-to-batch variation facilitates stable production scheduling for card manufacturers and cuts production waste.

With stable substrate performance and controllable thermal adhesive formulation, this series of PET adhesive films addresses key pain points in smart card composite processing such as delamination, blisters and insufficient weather resistance. Widely applied to bank cards, composite smart cards, dual-interface cards, contactless RFID cards, access control cards and transit cards, it provides highly reliable composite substrate solutions for smart card manufacturers.
