The EP180 Back Sealing Strip Packaging Machine is a compact, stainless-steel automatic pouch forming, filling, and sealing solution designed for consistent small-format pouch production. Engineered around stable horizontal sealing and reliable back-seal bag making, it processes composite packaging films with accurate registration, clean cutting, and repeatable running speed. With PLC control and customizable machine sizing, the EP180 is well-suited for manufacturers who require tidy seals, controlled bag length, and dependable output in daily operations—especially where packaging quality and hygiene standards matter.
Product Introduction
EP180 is a back-seal strip packaging machine built for efficient, continuous packaging of liquids, powders, and granules into neat pouches. Its structure focuses on maintaining steady film tracking, stable bag pulling, and uniform sealing performance, helping operators achieve consistent pack appearance from the first bag to the last. The machine adopts stainless-steel construction for durability and easy cleaning, while its sealing and cutting modules are optimized for reliable separation and professional retail-ready edges. For printed films, the integrated JULONG dual-color photoelectric eye improves mark detection accuracy, supporting precise cut position and improved overall presentation.
Product Features
Clean Horizontal Sealing With Pattern Options
The EP180 provides an 8–10mm horizontal sealing width to produce firm, visually consistent seals. Users can select either a diagonal mesh pattern with 1mm spacing or a straight pattern with 2mm spacing, enabling a seal style that matches product positioning and film characteristics. For liquid packaging, a dedicated 1mm leak-proof sealing line can be applied to reduce seepage risk and enhance package integrity during handling, stacking, and transportation.
Accurate Film Registration for Printed Packaging
To maintain consistent bag length and cut placement, the machine uses a JULONG dual-color photoelectric eye to track color marks on printed films. This improves registration stability during continuous production, reduces cut deviation, and supports a cleaner, more uniform pouch appearance—particularly important for branded, high-visibility retail packaging.
Flexible Cutting for Different Presentation Styles
The EP180 supports flat cutting or serrated cutting via an independent cutter design. A 3mm spacing between cutters helps deliver cleaner separation and more consistent edge finish, supporting applications where pouches need to look tidy for display, kitting, or secondary packaging processes.
Stable Bag Pulling With VFD Motor Crank Structure
Equipped with a variable frequency drive motor crank structure and heat-sealed bag pulling method, the EP180 delivers controlled pulling motion with smooth speed adjustment. This design helps reduce pulling fluctuation, supports steady forming and sealing, and contributes to consistent pouch geometry within the rated output range.
Stainless-Steel Build for Hygiene and Long-Term Reliability
Constructed from stainless steel, the machine is designed for packaging environments that prioritize corrosion resistance and convenient cleaning. The robust frame and practical layout help maintain long-term stability under routine workloads, making it a dependable choice for workshops and production lines that package multiple SKUs or run frequent batches.

Application Fields
Liquid Packaging
Designed to meet the sealing requirements of flowable products where leakage prevention is a priority. The optional 1mm leak-proof sealing line (liquid-only) supports stable pouch integrity for applications such as sauces, condiments, syrup-style products, beverages, and other liquids packaged in small pouches.
Powder Packaging
Suitable for powders that require smooth film pulling, consistent bag length, and clean cutting to maintain pouch appearance and improve throughput. Typical applications include food powders, beverage mixes, seasoning blends, nutritional powders, and similar dry, free-flowing materials compatible with composite films.
Granule and Particle Packaging
Ideal for granules and particulate products that benefit from neat bag forming and reliable separation. Common uses include small food granules and other particle-based products that can be packaged in composite film pouches with stable sealing and consistent cut position.
