High-Performance Packaging Rollstock
Precision rollstock film solutions engineered for automated production lines. With accurate COF control and excellent sealing performance, Sengelin Packaging helps your packaging line achieve stable, efficient, and zero-failure operation.
Technical Core for Higher Production Efficiency
Rollstock film stability determines packaging line speed, sealing consistency, registration accuracy, and material waste. Sengelin Packaging engineers rollstock films for smooth feeding, fast sealing, and precise forming on automated production lines.
Stable Operation for High-Speed Packaging Lines
Optimized for packaging machines from brands such as Bosch, Hayssen, and Ishida. By precisely controlling the coefficient of friction, the film runs smoothly during pulling and forming without drifting, slipping, or stretching deformation.
Fast Sealing with a Wide Heat-Sealing Window
Special inner sealant materials help achieve ideal seal strength within extremely short sealing time, effectively solving the sealing challenges caused by high-speed automatic packaging lines.
Precise Eye-Mark Alignment & Clean Slitting
Full automatic tension control and precision slitting help ensure accurate printed pattern registration, clean roll edges, and reduced material waste caused by inaccurate alignment.
