In recent years, polycarbonate (PC) overlay films have witnessed a significant increase in application of identity documents (such as ID cards and passports) due to the high strength, weather resistance and excellent processing performance. They have become one of the core materials for upgrading the security and functionality of the industry. The following is an analysis of the latest progress and trends in this field.
1. Technological upgrades drive breakthroughs in anti-counterfeiting performance.
Polycarbonate films are mainly used in ID cards for manufacturing data pages and transparent windows. The core advantage lies in the integration of multiple layers of anti-counterfeiting technologies. For instance, the Makrofol® ID series polycarbonate films developed by Covestro achieve dynamic color-changing effects through optical variable material (O.V.M) technology, supporting 1-3 levels of anti-counterfeiting features. They can also enhance the convenience of verification through laser-engraved tactile characters. Moreover, the launch of no-fluorescence polycarbonate films further reduces the risk of counterfeiting while being compatible with existing production processes, without the need for additional equipment adjustments.
2. Market Demand and Capacity Growth
The global market size of polycarbonate films reached 12.468 billion RMB in 2023, with an expected compound annual growth rate of 6.7% and is projected to exceed 18.512 billion RMB by 2029. China, as an important market, had a scale of 4.464 billion RMB in 2023, and the process of domestic substitution is accelerating. Through technological upgrades, we are gradually entering the high-end market, while international giants such as Covestro and Mitsubishi Chemical still hold the dominant position.
3. Expansion of Application Scenarios and Innovative Design
Polycarbonate film's applications have expanded beyond ordinary ID cards to include smart passports and electronic tags. Superlaser technology produces high-contrast pictures via numerous laser response layers, and PC laserable film simplifies production procedures while boosting anti-counterfeiting effects. Furthermore, there has been a surge in demand for velvet polycarbonate films in office and home ID cards, which has led to market sector diversification.
The innovative application of polycarbonate overlay film in the field of ID cards not only enhances the security and durability of the documents but also promotes the progress of materials science.
