Product Introduction
Efficient packaging for automated flow wrapping and high-volume production.
Back fin seal flat pouches feature a center back seal and two end seals, making them a practical packaging format for automatic flow wrapping lines. This structure is widely used when speed, consistency, and cost control are important.
Unlike many premade pouch formats, fin seal packaging is commonly produced directly from printed rollstock film on automatic packaging machines. This allows manufacturers to improve packing speed, reduce labor requirements, and maintain a consistent package appearance across large production runs.
High-Speed Packaging
Designed for automatic flow wrapping and large-scale manufacturing environments.
Cost-Efficient Structure
The streamlined package structure helps reduce material usage while maintaining product protection and shelf presentation.
Machine-Friendly Performance
Suitable for many horizontal and vertical flow wrapping systems, depending on product shape, film structure, and sealing requirements.
