As a high-performance barrier packaging material, cold stamping forming aluminum composite film possesses excellent moisture-proof, oxygen-barrier, and light-shielding properties. Its superior barrier characteristics can effectively resist the erosion of drug ingredients by gases, light, and external media, making it suitable for pharmaceutical packaging scenarios with strict barrier requirements in different climatic environments worldwide.
In the cold stamping aluminum pharmaceutical packaging system, the PVC film layer plays a critical role:
1. Cold Stamping Forming Compatibility: With excellent ductility and plasticity at room temperature, the PVC film can undergo significant plastic deformation during cold stamping to precisely form blister structures. Its room-temperature forming characteristics simplify the production process and effectively reduce energy consumption and equipment requirements.
2. Stable Shape Retention: The material maintains good formability after plastic deformation, ensuring that drugs are stably fixed within the blisters and meeting the safety requirements for drug transportation and storage.
3. Mechanical Performance Support System: The toughness and tear resistance provided by the PVC film layer form a protective barrier during cold stamping production, effectively preventing the internal brittle aluminum foil layer from being punctured or torn.
Aiming at the problems of blister rupture and false rejection by detection equipment that easily occur in traditional PVC pharmaceutical films during cold stamping processes, Yongrun provides professional solutions through continuous technological innovation:
• Blister Rupture Rate Optimization Technology: Upgrading the formulation system based on customer feedback has significantly improved the material's elongation at break, achieving a revolutionary breakthrough in reducing blister rupture rates during production. Test data shows that Yongrun's PVC pharmaceutical film experienced only 0-1 blister ruptures in 108 stamping tests, reducing the rupture rate from 2%-3% in traditional materials to below 1%, significantly improving production yield.
• Intelligent Detection Adaptation Technology: To address the challenge of false rejection, the R&D team has successfully launched a new generation of PVC-B pharmaceutical film products. By optimizing the surface microstructure and regulating optical properties, it effectively reduces interference from defect signals, fundamentally solving the problem of false alarms in detection equipment and providing core support for customers to reduce costs and improve efficiency.
Since 1998, Yongrun's R&D team has always been market-demand-oriented and established a closed-loop innovation system of "customer suggestions - technical R&D - product iteration." Facing the fierce market competition in 2025, the company adheres to the core value of "quality first" and has won wide industry recognition with stable product performance and a full-process service system. In the future, Yongrun will continue to deepen industry-university-research cooperation, join hands with customers to build safe and efficient pharmaceutical packaging solutions, and embark on a new journey of industrial development together.
