Product Introduction
The EP180 High-Accuracy Poly Bag Packing Machine is a PLC-controlled, automatic back-seal strip packaging system developed for stable, hygienic, and repeatable pouch forming, dosing, and sealing. Designed to run composite packaging films up to 180 mm in width, it integrates reliable mechanical transmission with dual-color photoelectric tracking to keep printed marks aligned and bag length consistent over continuous operation. The EP180 is engineered to support everyday production needs for liquids, powders, and granules, delivering clean package appearance, dependable seal strength, and practical operational flexibility for different product behaviors and film structures. For liquid applications in particular, a 1 mm horizontal leak-proof sealing line is built into the sealing process to enhance seal integrity, reduce seepage risk, and improve transportation safety. With standardized configuration including one set of bag-forming specifications, the machine provides a balanced solution for manufacturers seeking consistent output, controlled material usage, and repeatable quality across a wide range of small-format pouch types.
Product Features
Accurate Film Registration with Dual-Color Photoelectric Tracking
The EP180 uses a dual-color photoelectric eye in coordination with PLC logic to maintain precise tracking of printed films. This helps keep graphics centered, minimizes misalignment, and reduces scrap caused by incorrect registration. Stable tracking also supports reliable bag length control, improving overall packaging consistency and shelf presentation.
PLC-Based Control for Repeatable Bag Length and Cutting Consistency
A PLC control architecture enables dependable synchronization between film feeding, sealing, and cutting. This improves repeatability from bag to bag, supports long production runs with stable performance, and simplifies parameter management for different products and pouch sizes within the standard bag-making setup.
Practical Throughput for Medium-to-High Daily Output
With an operating speed of 20–40 bags per minute (depending on film type, product flowability, and dosing characteristics), the EP180 delivers efficient production while maintaining control over sealing and cutting. This speed range fits common requirements for routine manufacturing where consistent quality is as important as output.
Clean Separation with Flexible Cutting Options
To meet different retail and consumer-opening preferences, the machine supports both flat cutting and serrated cutting through an independent cutter design. A 3 mm spacing between cutters helps ensure neat edges and consistent separation, contributing to a more professional pack finish and improved user experience.
Stable Film Pulling and Reliable Sealing Performance
A variable-frequency motor crank structure combined with heat-sealed bag pulling promotes smooth film movement and stable tension control. The twisted edge adhesive sealing structure provides a neat back seal and good adaptability to commonly used composite films, supporting uniform seals that hold up well during handling and distribution.
Multi-Product Compatibility with Practical Filling Accuracy
The EP180 is suitable for liquid, powder, and particulate products, making it a versatile choice for facilities handling multiple SKUs. Measurement accuracy is rated at ±1–10% depending on packaging material, product characteristics, and target fill quantity—an effective range for many consumer and industrial packing tasks where consistent dosing and reliable repeatability are required.
Durable Stainless-Steel Construction for Hygiene and Long Service Life
Built with stainless-steel machine material, the EP180 is designed for demanding production environments where cleanliness, corrosion resistance, and durability matter. The structure supports easier cleaning and stable operation, helping reduce downtime and supporting higher equipment availability over extended use.
