High-Speed Marking for Flexible Film Packaging: Key Technologies for Efficiency and Reliability
In today’s rapidly evolving packaging industry, flexible film packaging is highly favored for its lightweight, durability, and versatility. However, as vertical form-fill-seal (VFFS) and horizontal form-fill-seal (HFFS) production lines continue to increase their speeds, achieving precise, durable, and low-maintenance variable data marking at high speeds has become a critical challenge. This article explores high-speed marking technologies for flexible film packaging, including Thermal Transfer Overprinters (TTO), Continuous Inkjet (CIJ), Thermal Inkjet (TIJ), and Laser Marking, to help businesses make informed choices based on their production needs.
Thermal Transfer Overprinters (TTO) remain the preferred solution for marking on flexible packaging films. Using a ribbon-based direct thermal transfer technology, TTO achieves high-resolution text, batch numbers, barcodes, and expiration dates without liquid ink. It offers consistent and reliable printing speeds exceeding 300 packs per minute and maintains clear contrast on OPP, PET, PE, and composite structures—making it ideal for food, pharmaceutical, and consumer goods packaging.
When extremely high speeds, non-contact printing, and continuous operation are required, Continuous Inkjet (CIJ) technology is the ideal choice. CIJ generates micro-droplets to mark moving films, supporting date coding, batch numbers, and traceability on various substrates. Syscode CIJ systems are known for quick start-up, stable ink adhesion, and low total cost of ownership, making them reliable partners for high-demand production lines.
Thermal Inkjet (TIJ) printers—including industrial-grade units and portable handheld models—deliver clear, high-resolution barcodes with minimal maintenance. They are suitable for medium-speed packaging, small-batch production, and flexible film pouches. The Syscode TIJ series supports quick cartridge replacement, high-adhesion inks, and optional white ink for dark films, ensuring marks remain visible and legible.
Laser coding (including CO₂ and fiber laser markers) achieves permanent, consumable-free marks through controlled ablation or color change. CO₂ lasers are suitable for coated films, while fiber lasers work well on metallized layers. Syscode’s compact desktop and flying lasers can be easily integrated into automated packaging lines, offering efficient and flexible marking solutions.
Selecting the right marking technology depends on film structure, production speed, code durability, and integration requirements. Whether using TTO, CIJ, TIJ, or laser marking, reliable systems enable high-contrast printing on flexible films for production dates, expiration dates, serial numbers, and compliance information.
With proven engineering, consistent performance, and a complete product lineup—from handheld inkjet solutions to high-speed industrial printers—these marking systems deliver efficiency, durability, and exceptional value for modern flexible film applications, helping businesses enhance productivity and market competitiveness.
