Product Introduction
The Pack Mate EP180 Back Sealing Strip Packaging Machine is a compact, automatic VFFS solution engineered for high-efficiency small-pouch production. It integrates bag forming, dosing/filling, and sealing into one continuous workflow, delivering consistent pouch shape and a clean, professional back-seal finish. Driven by a PLC control system and equipped with a JULONG dual-color photoelectric (optoelectronic) eye, the EP180 maintains stable film registration and precise bag positioning—helping reduce misalignment, improve sealing consistency, and keep package appearance uniform across long production runs. Designed for composite packaging films, it supports multiple product types including liquids, powders, and granules, making it a practical choice for daily manufacturing where reliability and repeatability are essential. With an output of 20–40 bags per minute, the EP180 provides a balanced combination of speed, control accuracy, and pouch quality for small-format packaging applications.
Product Features
All-in-one automatic operation for efficient pouch production
The EP180 combines film forming, product filling, and sealing in a single automated sequence. By consolidating key steps into one machine cycle, it minimizes manual handling, supports stable throughput, and helps streamline production scheduling for small-bag packaging tasks.
Accurate film tracking with dual-color optoelectronic sensing
Stable tracking is achieved through the JULONG dual-color photoelectric eye, which improves mark detection and registration accuracy on printed films. This helps ensure consistent cutting position, neat bag edges, and uniform sealing placement, especially during continuous high-frequency operation.
Clean back-seal structure with dependable sealing performance
The back sealing strip design delivers tidy sealing lines with a standard sealing width of 5–10 mm (no pattern), creating an orderly pouch appearance suited for retail-ready packaging. For liquid applications, an optional 1 mm horizontal sealing leak-proof line is available to enhance seal security and reduce leakage risk (applicable to liquids only).
Selectable cutting styles to match product and user experience
To adapt to different packaging requirements, the EP180 supports both flat cut and serrated cut via an independent cutter configuration. The 3 mm spacing between cutters contributes to stable separation performance while helping optimize bag opening convenience and visual presentation.
Stable bag pulling for consistent length and output quality
A variable-frequency motor crank structure with heat-sealed bag pulling provides smooth traction and reliable control of bag length. This stability supports uniform pouch dimensions, improves repeatability, and helps maintain consistent output at rated production speeds.
Composite film compatibility for diverse packaging formats
The machine is designed specifically for composite packaging materials commonly used in sachets and small pouches. This film compatibility, combined with stable registration control, supports reliable sealing and a clean finish across a broad range of routine production scenarios.
Multi-product adaptability for liquids, powders, and granules
With application coverage across liquid, powder, and particle products, the EP180 can be deployed in varied packaging lines. It is suited for plants seeking a flexible platform capable of handling different product forms while maintaining consistent bag quality and stable sealing performance.

Application Fields
Liquid sachet packaging
Designed for liquid filling and sealing where stable sealing integrity is critical. The optional 1 mm horizontal sealing leak-proof line (liquid-only) enhances sealing security and supports safer transportation and storage for leak-sensitive products.
Powder sachet packaging
Suitable for packaging powder products in small bags using composite films. Accurate registration and consistent sealing help maintain a clean look and dependable closure for routine factory production.
Granule and particle pouch packaging
Ideal for granules and particulate products that benefit from stable bag pulling and consistent cutting. The EP180 helps keep pouch length uniform, edges neat, and separation performance reliable.
General small-pouch manufacturing for multi-industry lines
A practical choice for manufacturers needing an automatic, PLC-controlled back-seal pouch solution with flexible cutting options and stable optoelectronic tracking. Suitable for production lines that require consistent pouch appearance, efficient output, and reliable daily operation across multiple product categories.
